All of my big game loads have Partitions loaded. purchase helps support my work in bringing you more awesome gun and gear articles. All of these rounds maintain supersonic speeds out to 500 rounds and probably will for another several hundred yards. The .243 Winchester was developed by wildcatters who immediately grasped the accuracy potential of the .308 parent case and then necked down the case to accept .243 caliber (6mm) bullets. There are several factors that influence the recoil energy. From the muzzle, we are looking at nearly a 1,000ft.lbs difference in the averages of the two cartridges. There are some key differences between the two modern cases. Using the data above let’s plug the numbers in the Beartooth Bullets Recoil Calculator. The Spiny Water Flea Could Wreak Havoc on the Most Pristine Waters in the Upper Midwest. Randy Bauman was lead instructor for seven years at the Boy Scouts of America National Camping School-Shooting Sports Section, and he has a lifetime interest in teaching others about firearms. The .308 seems to be at its best with 168-grain projectiles. The differences in bullet energy between these two rounds is obvious. There is no debate on this category when comparing the .243 and .308 cartridges. Our .308 will recoil with 20-foot-pounds of energy and a recoil velocity of 13 fps. We see that all of the .308 Win rounds leave the muzzle with over 60lbs/ft.s of momentum, several closer to 70, while the .243 rounds, besides the 55 and 58gr rounds, hover near the 40lbs/ft.s mark. While we agree that energy is important, we also think shot placement is as important if not more. A lot of factors go into the actual “felt recoil” that we can’t put numbers on for comparison. Copyright © 2021 Pew Pew Media, Inc. All rights reserved. Regardless of the difference, every round shows less than 5 inches of bullet drop at the 200-yard mark. As you can probably guess just by looking at the chart, the two rounds with the lowest bullet momentum are the 55 and 58gr rounds. While the .308 does have a history in tactical applications as well, it is not often enough for us to focus on that area either, especially with our second cartridge being the .243 Win. They also are a great platform for building long-range competition rifles as well as special purpose rifles for military and law enforcement use. This is Mil-Spec 7.62 NATO ammo that will run in all your semi-auto rifles as well as your bolt gun. Overall, we see a similar trend as we did with the short range trajectory.

Again, regarding the actual cartridges along with their case and bullet design, the differences in accuracy are non-existent. Also, keep in mind that some of these rounds might have less or more powder when used in reality, so the recoil energy may vary a little. It’s a great medium to large game rifle and can be used for just about any large game animal in the world, barring a few. While the .243 Win rounds have an average that is only about 3 one hundredths behind the .308 Win rounds, this is quite a bit for sectional density. The .308 is a 30 caliber bullet and lends itself very well to both big game hunting and precision shooting. This site is protected by reCAPTCHA and the Google Hornady Custom Match Rifle Ammunition 168 Grain .308. It does shine when it comes to trajectory. There are several choices here, but the 168 grain Sierra MatchKing bullet is great for long-range shooting and considered by many to be the best long-range bullet available. On the other hand, the .243 rounds come in between 8 and 12ft.lbs of energy. On the other hand, a .308 stoked with Hornady’s 168-grain ELD Match ammo has a BC of .523. The .243 comes in a wide range of bullet sizes and makes it a pretty versatile gun in the hunting world for the type of game it can effectively be used against. The cartridges both enjoy a wide range of bullet weights and styles that can be used for everything from varmint hunting, to big game hunting, to long-range shooting and competition. At the muzzle, the .308 rounds have bullet energies above 2,500ft.lbs, and all remain between 1,000 and 1,400ft.lbs at the 500-yard mark. Let’s take a look at the larger sample set and see if we can get a more definitive look at how these two cartridges compare in their bullet velocities. This round has a great BC for .308 rounds (.45), and when paired with the velocity and long-range trajectory, you have an excellent round for precision shooting. As the bullets lose velocity and as outside influences act on the bullet, it loses altitude. There are .308 rounds with lower BCs that look more like the .243 rounds, but there are also rounds with close to double the BCs of some .243 rounds. Three of the most revered deer-hunting rounds in a head-to-head-to-head comparison. What’s your take on the SMK loaded Gold Medal Match?

And if we take them out, the average only increased to 963 yards. (20.9 at 700 yards and 28.6 at 1000 yards). . Compared to the ranges that we used with the smaller sample, the difference between the two rounds is not large but still apparent. Initially designed as a target/varmint round, it may be used for animals such as coyotes, blacktail deer, whitetail deer, mule deer, pronghorns, and wild hogs.Rounds of at least 90 grains are better suited for hunting the larger of those while rounds less than 90 grains are more suitable for varmints. Meanwhile the poor little 243 Winchester, which is the 308 Winchester case necked down to accept 243-caliber bullets, is suspect. So while the bullet drop might be more pronounced, the BC and heavier weight of the .308 might help it resist other environmental factors such as wind, when taking long range shots compared to the .243. The Hornady Custom Match Rifle ammo is a solid choice for the long-range shooter. So when we increase the amount of samples that we have, we are still seeing the same disparity between the two cartridges.

There just is not enough mass to ensure consistent penetration no matter how good the bullets we are shooting are constructed. Even when we take out those rounds, the average BC for the .243 Win only increases to 0.35 which is still enough difference between the .308 average to warrant discussion later.
