Head to Head: .308 Winchester vs. 7mm-08 Remington – Latest

Here, we’ll look at two different cartridges whose ballistics performance is otherwise pretty close to the same.

The 7mm-08 came out in the 1980s, so the 7mm-08 vs. 308 debate isn’t as old as some other cartridge debates that have been going on for over a century.

Both are good for hunting and shooting competitions, and we’ll be the first to tell you that if the conditions are right, either one could become your go-to cartridge in the field.

We won’t say that one cartridge is better than another. Instead, we’ll look at the facts about how their functions differ.

We can now say with more certainty that each of these cartridges is best used in a certain type of shooting.

A Brief History

7mm-08 Remington

Remington made the 7mm-08 in the 1980s to give shooters a modern caliber and cartridge that worked as well as the older 757 Mauser.

The 7mm-08 was made by making the muzzle of the.308 Win shorter. It can shoot bullets that are 7mm smaller in diameter than the original.

Before it was even made, the 7mm bullet’s popularity went through the roof because it shot better and had less recoil than bigger hunting cartridges.

.308 Winchester vs. 7mm-08 Remington

The 7mm-08 is a great choice of cartridge for hunting medium-sized to large animals. The goal of the design was to lessen the felt recoil while keeping a bullet weight and speed good for killing animals at long range.

Even though there are people who like the 7mm-08, it is not as popular as other hunting cartridges. Even though most bullets weigh between 120 and 150 grains, there are some bigger rounds that are similar to the standard hunting rounds for the.308.

.308 Winchester

When Winchester came out with the.308 Winchester in 1952, it quickly became a standard in the American hunting community. After a short time, the military adopted it because of how well it worked, and it was used a lot in Vietnam.

Even though the NATO version of this round didn’t last long, serious shooters and hunters will always be fans of it. Because this bullet is bigger, it has a longer range, goes deeper, and kills faster.

If the conditions are right, this cartridge can be used to hunt any kind of big game anywhere in the world.

The performance of the.308 is good enough that it is used by police and military sharpshooting units in addition to hunters.

Even though the cartridge isn’t as popular in this subculture as it used to be, the fact that it is still used by some tactical forces is a good sign for it.

This cartridge is popular because it works well. Because of this, shooters and hunters can choose from a wide range of bullet weights and calibers to find the right one for every situation.

Before we compare two cartridges, we like to quickly look at their case and bullet specs. When we look at the different ballistic and other performance characteristics of these two cartridges, we can get an idea of how they might act and why they are similar or different.

The.308 Win is the ancestor of the 7mm-08 cartridge, which has a smaller neck diameter than the.308 Win because it was made to fire 7mm bullets.

Because the 7mm-08 has a bigger case and a longer bullet that sits lower in the chamber, it can hold less powder than a.308 round.

Even though the total length of both cartridges is the same, the.308 Win. The base diameter of the cartridge is just a little bit bigger.

Despite the changes, the case size and maximum pressure of both cartridges are the same. When it comes to how they shoot, the 7mm-08 and the.308 are very similar, except for a few key differences.

We chose five rounds from each cartridge, each with a different bullet design and weight, to show how these two are different. We know that there are a lot of options, and that the round you like might not be listed here.

It’s not because we don’t value the other rounds as much; we just needed an arbitrary cutoff, and ten seemed like a good, round number that still gave us enough options without making the graphs too crowded to draw any meaningful conclusions.

.308 Winchester vs. 7mm-08 Remington

Even though we’re only going to plot ten rounds, we have a lot more information. At the end of each section, we’ll show you the average of twenty rounds for each cartridge.

This will show you that our sample size is a better reflection of how these cartridges work overall. You’ll get a full rundown of all rounds at the end of the piece.

These are also factory loads. Hand-loaded cartridges are often filled at a higher pressure, so we didn’t include them.

Even though handloading and how much a cartridge can hold are interesting topics, they are not what this paper is about. Since most people use factory loads, we will focus on the most common types of ammunition sold in stores.

Before we start making comparisons, it’s important to know where the data will come from. Most of it comes straight from the manufacturer, and the rest is completely new research made possible by reliable ballistics calculators that our team made.

There’s a chance that these numbers will be different from what chronographs and other physical methods on other people’s weapons platforms show.

Computer-made statistics are a great way to compare two cartridges because each gun might give slightly different numbers.

Because of this, the exact numbers might be different depending on where you look and what kind of gun is used, but the general trends should stay the same.

Now that that’s out of the way, we can compare and contrast the 7mm-08 and.308 cartridges.

Recoil

A lot of shooters choose their ammunition based on how much the gun recoils.

It could be because they’re afraid of the kick, but it’s more likely because it’s hard to hit your target with several bullets at once. Every cartridge has a certain amount of “recoil” or “kick” that needs to be dealt with.

In this section, we’ll compare the real ft.lb. how much force these two cartridges put out when they are fired.

Because of the effect of other, harder-to-measure factors, what we’re measuring doesn’t really translate to “felt recoil.” It’s safe to say that more kick means more recoil energy from one round to the next.

These numbers were made by putting the muzzle speed, bullet weight, gun weight, and powder charge into a ballistic calculator.

We used Nosler load data to figure out the average amount of powder in each cartridge, and then we used that same amount of powder every time that cartridge was fired.

In general,.308 ammunition has a few more foot-pounds of power than its 7mm-08 counterpart. Even though the recoil from different cartridges can be very different, it is safe to say that it is enough to make even the steadiest hands shake and maybe miss the target.

Each.308 bullet has between 20 and 23.5 foot-pounds of recoil energy, while each.7mm-08 bullet has between 17 and 18 foot-pounds.

There are only about 6 lbs. not much difference between them, so any of them will work. Some customers may be swayed by this alone, but the ballistics and other performance metrics are more likely to sway the majority.

The recoil from these two cartridges is about the same as what you’d expect from a handgun, but it could be different depending on things like the weight of the gun, the length of the barrel, and the amount of powder in the cartridge.

Most of the difference in the numbers, which can be off by a few foot-pounds, comes from the powder charge used by the manufacturer (not available).

We looked at a large number of standard factory loads for each of these cartridges to find out how much they recoil.

The results are in the table below. Let’s see if the same things happen when we figure out the recoil energy. These numbers were also made with the same variables that were used before.

Average Recoil (ft.lb)

.308 Winchester7mm-08 Remington
22.1517.18

There isn’t much difference between the two cartridges. The.308 Win makes about five more foot-pounds of force than the 7mm-08.

This is the same as what happened before. We’ve already said that the.308 has a more noticeable increase in recoil energy, but we can’t say if that will be enough to make you choose one gun over the other.

How well the rest of the performance is optimized will determine if a few more foot-pounds of energy make a difference or not.

Ballistics

Here, we’ll look at a few groups of ballistics so that we can compare cartridges on a level playing field.

If you know how each cartridge works in different shooting situations, you can choose the ones that will work best for hunting or other shooting needs.

We’ll figure out speeds, ballistic coefficients, and paths at both close and far distances.

.308 Winchester vs. 7mm-08 Remington

Even though we’re looking at each group separately, we think it’s important to point out that this is only a small part of the picture.

Even subfields that have nothing to do with ballistics affect and are affected by the others. When we talk about how to use what we’ve learned, we’ll try to put everything together.

Velocity

Bullet speed should be one of the most important things you think about when packing for a hunting trip. When a bullet is moving faster, things like wind and gravity have less of an effect on its path.

If bullets can keep moving faster than 1,125 feet per second, then these forces don’t matter at all. When these things are kept to a minimum, it’s easier to get a good shot.

For the best terminal ballistics, hunters need a certain muzzle velocity (i.e., bullet expansion and penetration). Most of the time, the maker will tell you what speed you need.

Then, let’s look at our 10 rounds and compare the speeds of these two cartridges. The manufacturer gave us all the information we need to figure out the bullet’s speed (in feet per second) from the muzzle to 500 yards (Graph 2).

Both cartridges fire at about the same speed. The 7mm-08 has a slightly faster muzzle velocity and a slightly longer effective range (500 meters vs. 400 meters), but several.308 rounds are competitive. Also, the average muzzle speed of the 7mm-08 at all range markers is less than 100 feet per second.

There is no way to tell which round came from which cartridge. Instead, they are all mixed up together. Based on these numbers, the speed of a given round varies a lot from cartridge to cartridge.

It’s not clear whether the.308 or the 7mm-08 maintains a higher speed throughout its flight, but this graph shows that both cartridges do a good job of keeping their speed.

Even at 500 yards, all of these bullets are still moving faster than the speed of sound. This is an amazing feat.

Let’s find out what the average speed is for each cartridge when we get more factory loads. Also, we’ll show you how fast each cartridge can usually go over the speed of sound.

Average Velocity (ft/s)

Yards.308 Win7mm-08

1002521.52617.9
20023202410.9
30021822198.7
4001946.52021.2
50017751833.2

The average speeds of these shots follow the same general patterns as those we’ve already talked about. The 7mm-08 is about 100 feet per second faster than the.308 from the muzzle to 200 yards.

Even though the gap between the two guns has shrunk, the 7mm-08 is still better from 300 to 500 yards. Again, many of the bullets in each cartridge move at the same speed, so statistically speaking, the differences between the averages don’t mean much.

If you’re wondering why it matters when a bullet slows down to subsonic speeds, it’s because the bullet becomes less stable when the sound wave it made behind it catches up to it. From then on, it’s less clear where the bullet will end up.

Average Supersonic Limit (Yards)

.308 Winchester7mm-08 Remington
1023.71035.5

When we look at how quickly the two cartridges lose speed, we find that they are very similar. So, these averages show that they both slow down to speeds below supersonic at about the same distance.

Both are slowing down to subsonic speeds, which is about a kilometer on average. These numbers were calculated using standard conditions at sea level. The actual values may be different depending on where you live and what time of year it is.

Ballistic Coefficient (BC)

The ballistic coefficient can be used to estimate how aerodynamically efficient a bullet is.

The equations being solved show that a bullet with a higher BC has less air drag, is more stable in crosswinds, and is less likely to drift in the wind than one with a lower BC.

This means to keep your speed up and be accurate at the same time.

There is no noticeable difference between the ballistic coefficients of these two cartridges. However, if we took the average of all five rounds from each cartridge, the 7mm-08 would be the winner (.44 vs .434).

We can’t say for sure that this pattern would be the same for any set of five rounds for either player. Based on what we saw with the speeds of these two types of cartridges, it seems like it depends more on the round than on the cartridge itself.

.308 Winchester vs. 7mm-08 Remington

In the next section, we’ll use a bigger sample size to compare the ballistic coefficients of these two cartridges.

Both of these cartridges have high enough ballistic coefficients for everyday shooting, but neither is as good as cartridges used in long-range shooting competitions where bullets are shot from 500 yards or further.

Average Ballistic Coefficient

.308 Winchester7mm-08 Remington
0.4340.418

We think that the size of our sample was too small to be able to say anything for sure about the two cartridges. When more data is added, it turns out that the.308 Winchester has a better average ballistic coefficient than the.223.

Some purists might say that the difference of 2/100s between the two is important, but those of us who only use factory loads wouldn’t know the difference if it hit us in the face.

It’s also important to remember that if we played for another twenty rounds, the difference might go away or even switch places.

The main point is that both of these cartridges have high-BC options in the range of 0.4 to 0.5 if you need them.

Trajectory

The trajectory of a bullet is very important for competitive shooting or hunting. In an ideal world, the bullet should go a long way without losing too much height, which we’ll call “bullet drop” (inches).

When you drop a bullet, it makes it harder to shoot accurately and takes more work to get the same results every time.

The rifle will be set up for a certain number of yards, and we’ll compare how well the two cartridges work at close and far ranges.

Before we do that, however, we’d like to show you how horizontal the paths of these two cartridges are. We chose two rounds from the same company that were the same size, weight, and ballistic coefficient (Graph 4).

When you look at the flatness of the 7mm-08 and the.308, there isn’t much of a difference between the two.

We’ve said this before, and we probably will say it again before this article is over: these two cartridges are almost exactly the same.

This chart shows that the difference in how far a bullet falls at 500 yards is rarely more than two inches. Let’s look more closely at specific range increments with different types of ammo for each cartridge to see if there are any differences.

Short Range Trajectory

These two rounds are great choices for close-range hunting of medium-sized to large animals. When we look at these two cartridges’ 100-yard-targeted rounds, we can see how they compare.

The manufacturer’s information on bullet weight, muzzle velocity, and ballistic coefficient was used in a ballistics calculator to get the results (Graph 5).

Every bullet hits the 200-yard target within three inches, and the 7mm-08 and.308 are about half an inch apart on average. We don’t see any link between the two cartridges either. At 300 yards, the differences between how the.308 and the 7mm-08 drop their bullets become more obvious.

Even if we look more closely, we can see that each bullet lands about 4.5 inches away from the other. On average, the bullet drop of the 7mm-08 is about an inch less than that of the other calibers.

The most important difference between the two rounds is still less than a foot. Even though a difference of six inches in aiming might seem like a lot when you have the deer of a lifetime in your sights, these cartridges work the same at close range.

After more shots are counted, let’s see what the average short-range trajectory is for these two cartridges.

Average Bullet Drop (Inches) at Short Range

Yards.308 Win7mm-08
50-0.125-0.165
10000
200-4-3.57
300-14.5-13.2
400-32.8-30

Based on these numbers, we can see that the 7mm-08 Remington has a small edge. Its bullet drops about half an inch at 200 yards and 2.8 inches at 400 yards, which is less than the.308 Winchester.

We’ve said several times in this post that you don’t shoot averages in the field, but if that’s all you have, the 7mm-08 Rem has a slightly flatter trajectory than the other options.

Yet, as we could see from the graphs of the smaller samples, both cartridges can be used to shoot flat.

Long Range Trajectory

Let’s take a step back and look at how the 7mm-08 and the.308 caliber behave at long range.

It’s important to know how these cartridges work at distances of 300 yards or more, since it’s common to take shots from this far away when hunting medium-sized to large animals.

Also, target shooters who do competitions or just like to practice their skills may find these ranges more appealing.

Like the short range trajectory, the bullet drop for these 10 rounds is measured in inches. At 200 yards, the weapons were set to zero, and measurements were taken every 100 yards from 100 yards to 700 yards. Similar methods were used to gather data on the short-range trajectory (Graph 6).

Even from 500 yards away, you can’t tell the difference between the two cartridges. Between 300 and 500 yards, the cartridges work well, but the 7mm-08 tends to be a little flatter than the others. The most a bullet can fall with these two cartridges is three inches.

The 7mm-08 rounds drop an average of 80.6 inches at 600 yards and 120 inches at 700 yards, while the.308 bullets drop an average of 91.5 inches at 600 yards and 133.7 inches at 700 yards (700 yards).

But there are some.308 rounds that fly straighter and hit harder than some.7mm.08 rounds. Again, the bullets are more important than the cartridges themselves.

Average Bullet Drop (Inches) at Long Range

Yards.308 Win7mm-08

500-50.3-46.7
700-137.6-125.9
1000-401.6-373.3

When it comes to the average, having more rounds has the same effect as having more rounds did before. At 500 yards, the difference is less than four inches. Given how close the averages were, there was a lot of overlap on the graph.

At 700 yards, there is only about 12 inches between them. Even though there are factory loads made for that, this is not usually how these cartridges are fired at the factory.

It can make a difference, but not often. From ranges within 500 yards, the average difference is less than 4 inches at 500 yards and gets smaller as you get closer to zero.

Stopping Power

Most hunters choose a hunting cartridge based on how hard it hits. To make sure the animal you shoot at dies quickly and painlessly, the bullet you use must have enough force, or you’ll have to follow it for another thousand yards after you shoot.

Whether or not a bullet kills a game depends on many things, such as its energy, how deep it goes, how it breaks up, and what kind of wound it makes.

This topic could be the subject of its own article, but for the purpose of comparing two cartridges, we will focus on their energy, their ability to penetrate, and their momentum.

The main reason for sticking with these three is that the resulting numbers are better for comparing pairs of cartridges than single rounds. This is when tools like ballistic gels come in handy.

Also, we’ll say right away that we don’t think any of the three things we’ll look at is a perfect way to predict how well any of these rounds will kill game. Even if we think about all three, there are still things we don’t know.

.308 Winchester vs. 7mm-08 Remington

It’s very important that your shots are accurate. Still, by comparing the three things that affect stopping power, we can learn a lot about how these two popular hunting cartridges are different and how they are the same.

Energy

When the powder is ignited, it combines with the bullet’s mass to make kinetic energy, which is what moves the projectiles downrange. When this energy hits the target, it does a lot of damage to tissues and organs.

Most of the time, the cartridges are used to kill big animals like deer, bears, elk, and moose, which all need more than 1,000 ft.lb. of strength.

We agree that it’s important to know and understand the bullet’s energy level when using these rounds for hunting, but we also know that these recommendations are not set in stone. At least as important as the force of the bullet is how well you aim.

We will measure how much force or energy each of the two cartridges has from the barrel to 500 yards. The information used here came from the producer (Graph 7).

When fired, the heavier.308 rounds have more energy than any of the 7mm-08 rounds we chose, and they tend to keep that lead out to 500 yards, but the 7mm-08 rounds are not that far behind in terms of force.

For distances over 300 yards, the average bullet energy of these two cartridges is within 100 foot-pounds of each other. Yes,.308 rounds are the most powerful, but some 7mm-08 bullets, like the Hornady SST, are more powerful than multiple.308 rounds.

All of these bullets have more than 1,500 foot-pounds of force. at 200 yards, and several of them still have that much power at 300 yards.

All of them have at least 1,000 ft. lb. of energy, except for the 7mm-08 Federal Power Shok 150gr bullet. up to 500 yards away. The problem is that it’s hard to aim accurately from so far away.

From what we’ve seen, there doesn’t seem to be a big difference between the two cartridges, at least not with the rounds we chose.

There may be more powerful rounds available for both the.308 and the 7mm-08 calibers than the ones we chose for this comparison, so there is no clear winner.

Even if one has a slight advantage in firepower, it is never enough to kill game reliably, especially if both shots hit the target in the vitals.

Even though these sample rounds may not show a big difference between these two cartridges, we can see if there is a trend by looking at the averages.

Average Bullet Kinetic Energy (ft.lbs)

Yards.308 Win7mm-08
027232464.9
1002319.92094.6
2001966.51777.5
3001657.91490.1
4001389.71252.1
5001109.51034.8

When we look at a much larger set of data, we see the same patterns as before. For example,.308 Win bullets have more kinetic energy from the muzzle to 500 yards than.7mm-08.

When we look at our lower sample set, we can see that the average KE for the.308 Win rounds has gone up a little bit. Even though these are just averages, the.308 Win.

If you want a round with the most kinetic energy, you will have more options at the higher end of the energy scale. As we saw in the graphs above, there is, of course, a lot of overlap between these cycles.

Penetration

The bullet’s ability to go through the target is one of the most important parts of its stopping power. In some situations, a shallower wound channel may be better.

However, on larger game with thicker skin and bones, a deeper wound channel is sometimes needed to reach and hurt key organs.

In order to figure out how well different cartridges work, it is common to compare their penetration by measuring the sectional density of the bullets. Taking into account how heavy a bullet is and how wide it is, this number was found.

The bullet will be able to go farther if the cross section is more dense. For the sake of clarity, let’s ignore the fact that the bullet expands and breaks apart.

The 10 rounds we chose to look at for this analysis are shown in a chart below (Graph 8).

Concerning the sectional densities of these two rounds, there are many interesting things to talk about. First, there’s no doubt that the sectional densities of these two cartridges are almost exactly the same.

The standard deviation (SD) of the 7mm-08 rounds is 0.251, while the SD of the.308 rounds is 0.26. It’s interesting that the 7mm-08 uses bullets with less energy at the muzzle. A 165-grain.308 bullet has the same sectional density as a 140-grain 7mm-08 bullet.

Because the 7mm-08 has a smaller diameter, more force can be put on a smaller area. This makes it easier to penetrate. The 7mm-08 sells well because it has a better trajectory and the same stopping power and penetration.

And the energy comparison proved it. When it comes to penetration, there isn’t enough difference between the two to choose one over the other. Since they can both go deep, the design of the bullet is what makes the difference.

.308 Winchester vs. 7mm-08 Remington

Now, when we look at our bigger sample size in the table below, we see that these conclusions may not hold up when we add a lot more rounds to the equation.

Average Sectional Density

.308 Winchester7mm-08 Remington
0.2480.258

Still, we can see that the averages for the two cartridges are pretty close to each other. This means that both cartridges will have rounds with higher sectional densities.

Since 150gr bullets were used in both calibers, the average for the 7mm-08 Remington went up to.258 and the average for the.308 Win went down to 0.248. Again, the difference is not big enough to say that cartridge is better in general.

Momentum

When we talk about bullets and momentum, we mostly talk about how well they can get around obstacles. To put it simply, an object’s momentum is its ability to keep moving in the same direction. This is for a wide range of people, from tactical shooters to hunters.

It depends on the situation, but you don’t always need more speed. As a sign of whether or not the projectile will go through an obstacle or a suit of armor, tactical marksmen may want the projectile to have more momentum.

The same rules of thumb apply to hunters, who may need a round that can still go through thick hide and bones. In other situations, a bullet with less speed might be enough. And the shape of the bullet still needs to be thought about.

This graph shows that rounds tend to group together by cartridge type, but there is some overlap between the two at further markers.

The.308 Win. produces a much faster muzzle speed than the 7mm-08, but the difference between the two is only a few pounds per foot. at 500 yards.

Once each cartridge has had fifteen more rounds added to it, the information about momentum will be looked at.

Average Bullet Momentum (lb/ft.s)

Yards.308 Win7mm-08
Muzzle64.155.8
10059.151.45
20054.447.4
30049.943.4
40045.739.48
50041.736.36

Based on these calculations, it looks like.308 Winchester bullets have between 9 and 5 lb.-ft. 7mm-08 Remington bullets have more speed.

When compared to lighter 7mm-08 Remington rounds, these have a lot more momentum, which is what the momentum equation says should happen.

Even though some 7mm-08 cartridges have similar momentum numbers, the.308 Win cartridge almost always gives the bullet more momentum, as we’ll explain in the “Applications” section.

Accuracy

It is hard to compare the accuracy of different cartridges. We think that accuracy is also affected by things other than the cartridge itself. Most important is the shooter. The type of gun you use and the type of bullets you use are both important.

The only real way to figure out how accurate a gun is is to shoot a lot of rounds at a range and count how many hit their target. Even then, there are a lot of things that you can’t control that could make the results change from day to day.

But we can use the evidence we’ve already looked at to figure out how true our assumptions are.

The speeds of the two cartridges are pretty close to each other. The 7mm-08 might have slightly faster average speeds and higher ballistic coefficients, which would help keep the bullets on the right path in the field.

You should probably take this with a grain of salt because there are.308 rounds that perform as well as or better than this.

We found that the trajectories of the two cartridges were the same and depended on the type of bullet used.

Even though the sample size for this comparison is small, the 7mm-08 bullets had a much flatter path than the.308 bullets, especially at long distances. Up to 150–200 yards, both of these cartridges work the same.

Recoil is another thing that affects accuracy. The recoil of a gun can make a beginner shooter flinch, which is one of the most common reasons why shots are missed in the field.

We can see that the.308 had a little more kickback than the 7mm-08. But the recoil from either of these cartridges could make it harder to shoot accurately, especially if you shoot a lot of shots quickly.

After taking everything into account, we can’t say for sure which one is right.

Many people get very heated when they talk about how accurate the 7mm-08 is compared to the.308, but the truth is that they have just trained more with one of the two weapons. When used by a good marksman, these cartridges give the gun a lot of accuracy.

Price and Availability

Many of us agree that price shouldn’t be the only thing we think about when choosing between different kinds of ammunition, but it is still an important factor.

This post includes the price of 20 rounds of the ammo we choose to use so that you can compare prices.

When you compare the prices of these two cartridges, you won’t find much difference, just like when you compare the other ballistic parameters we’ve looked at. The prices are, of course, subject to change based on what the market says.

Even though the.308 rounds might be a little cheaper than the 7mm-08, each of these guns will have both very cheap and very expensive types of ammunition.

Even though both the.308 and the 7mm-08 are commonly used, the 7mm-08 is much easier to find because of how popular its parent caliber is.

Larger places that sell ammunition are more likely to have it in stock, but there are fewer choices of bullet designs and weights than with the.308.

Applications

As we go through these parts, we’ve put all the average tables we’ve used below so they’re easy to find.

There aren’t many times when a.308 would be better than a 7mm-08. You’d have to shoot a lot of different rounds and look for differences between them to see if there are any real differences in how they work.

Both of these cartridges work very well at close ranges on medium-sized to large animals. Up to 300 yards away, the stopping power stays the same.

However, the changes in trajectory make it harder, but not impossible, for the user to hit their target. You can get a flatter trajectory with the 7mm-08, but you can also use.308 rounds.

Any of these cartridges will be able to kill any North American game animal at close range, and at longer ranges, they will be able to kill medium-sized animals.

Even though these light loads have low muzzle energy, they work well on medium to large animals because, with the right bullet design, they can penetrate as well as heavier.308 rounds. Many different things can be done with the cartridge.

We also noticed that the momentum numbers for each of these cartridges are pretty close. On average, the.308 Win has a little more momentum than the 7mm-08 Remington rounds. Does this give you enough information to choose between the two cartridges?

We’re still not sure about that. When hunting bigger game and need something to go through the animal cleanly, the extra speed may give you peace of mind. We’re also sure that some of you have used a 7mm-08 rifle to kill big animals.

The.308 Win may look like the better choice based on the numbers, but it’s not even close to being the clear winner.

Think about the sectional density as well. The 7mm-08 rounds had a little bit of a bevel, which might make them more likely to penetrate and make up for the fact that they didn’t move very fast.

From a tactical point of view, this change in speed could be an advantage for the.308 Win. In this case, however, the lack of tactical 7mm-08 ammunition is a major factor.

The military and police have used and still use the.308 Win because it is reliable and because the cartridge has a lot of momentum, which helps it break through heavy armor and other barriers.

If you tend to jump, the 7mm-08 might be a better choice than the.308 because it has less recoil. But both could be hard for a beginner hunter or shooter to learn at first.

If you’re mostly interested in long-range shooting or do most of your shooting at a range, the 7mm-08 may be a better choice because it has less recoil and a slightly better trajectory. When comparing BC, the.308 offered better options, but trajectory must also be considered.

Even though this may not be an exact comparison, rifles with a 7mm-08 chamber tend to be lighter than those with a.308 chamber. Both have quick triggers, which makes them great for moving heavy loads through dense forests.

We think that how many of these rounds are available will be the deciding factor. As well as having a wider range of weapons, it will be easier to find.308 ammunition if you need something specific than 7mm-08 ammunition.

The Best Rounds

At the end of our cartridge comparisons, we like to look at the ten rounds we’ve been using throughout the article and choose a couple rounds from each cartridge that we think might work for certain shooting situations.

We don’t think that our choices are the only good ones, and we also think that a lot of other rounds could do very well in the same conditions. You should use any method that makes you feel comfortable.

Top Hunting Round

The Nosler Ballistic Tip 165gr is a good choice for the.308 Win. This works well as an alternative for medium-sized to large game. The bullet has 1,300 foot-pounds of force at 500 yards. It has a lot of power, so it can kill animals as big as elk.

If the shot is placed correctly, this bullet can still do terminal ballistics and kill cleanly. As long as you stay within that range, everything will be fine.

The.308 has one of the best long-range trajectories, making it easy for skilled shooters to hit targets up to 400 yards away. Outside of that range, however, the ballistic coefficient of the round may be affected by the environment.

We were impressed by the 140gr Nosler Trophy Grade AccuBond round for the 7mm-08. This is a great round for hunting medium to large game because the AccuBond bullet penetrates very well.

At 500 yards, it has more than 1,000ft.lb of energy, so you don’t have to worry about not having enough power to drop game.

It has a great bullet drop at 300 yards (12 inches when set at 100 yards) and a ballistic coefficient (BC) of.421, which makes it a great hunting cartridge.

Top Range Round

We think the best.308 Win range round is the Hornady BTHP Match 168gr. When you plan to shoot a lot of rounds at the range, this type of ammunition’s low price is a big plus.

When you take into account this round’s speed, long-range trajectory, and good ballistic coefficient for.308 rounds (.45), you get a round that is perfect for accurate shooting.

Even though most competitive shooting uses hand-loaded ammunition, our team recommends the 139gr Hornady Superformance SST cartridge out of the five factory loads we looked at.

The 7mm-08 round has a high ballistic coefficient (BC) of.486 and an amazing velocity for its price. At 500 yards, the bullet only falls 39 inches, and at 700 yards, it falls 105 inches, which is very low for a factory load. With a gun that has 18ft.lb. of recoil, you can spend all day at the range shooting rounds.

Conclusion

As we’ve seen, it’s not always normal for cartridges to have big differences in how well they work. Differences between the 7mm-08 and the.308 in how they shoot are hard to spot unless you look closely.

But the two cartridges are different enough from each other that they can serve different but related markets.

We hope that this essay has helped you understand these small differences and how they affect your performance on the field.
