Because of this, these numbers might fluctuate a bit in reality, given your rifle and the actual powder charge used by the manufacturer. This is another comparison that matches an established short action cartridge (the.243 Winchester) against a more specialized new short action cartridge (the 6mm Creedmoor) of similar performance. If you’re looking to choose between one of these cartridges, it’s going to be a wash when it comes to recoil.

Accuracy is always a tough topic to broach when trying to compare two different cartridges. As most of us know, Winchester unleashed its 243 Win. The theory behind sectional density and penetration is that the heavier the bullet, the more mass that is behind it when it hits the target. Regardless of what the shooting situation is, recoil is going to run through your mind at some point when deciding on a cartridge. Deeper penetration is not always an indicator of a better round or cartridge. The 6mm Creedmoor was introduced specifically for these shooting applications. 6.5 creedmoor vs .243 win Discussion in 'Firearms Chat' started by kwaynem, Jun 22, 2019. From 500 to 700 yards, we do start to see the 6mm Creedmoor rounds separate themselves from the rest of the pack regarding flatness. Another trend that we see in this graph is the rate that the bullets from each cartridge bleed velocity. From this comparison, it out performs the .243 in a lot of areas when it comes to target shooting. The sectional density of bullet B is going to be slightly higher than bullet A. It might not be a competition round, but it is fun to mess around with while on the range with friends. Precision, wrote the piece on his necked down 6.5 Creedmoor, and moved on. My buddy John Snow—now editor of Outdoor Life—was writing an article about the pleasures and pitfalls of developing his own cartridge. The 6mm Creedmoor has two rounds at .512 and .536 while the .243 Win rounds do not crack the .4 mark. We will also bring these tables back at the end of the article when we discuss the applications of both these cartridges. You might be wondering how it is tough, just shoot and compare. vs. .458 Lott• 7mm Rem. The old 243 Winchester can beat that by about 300 fps. Ballistically, it is also high grade. The trajectories of these cartridges are also more than suitable for hunting. The 58 and 55gr .243 rounds are extremely flat with only 6 and 7 inches of bullet drop while the remaining rounds fall to the 10 and 11-inch range. The zero range was set at 100 yards and the data points carried out to 300 yards (Graph 5). At this point, the average difference at the 500, 600, and 700 ranges are 7.8, 16, and 28 inches respectively. Without much momentum, you might only get a shallow wound which might drop the animal, but it could mean a long day of tracking. While both bullets have the same mass, bullet B is concentrating all of that mass in a smaller area, which in theory, should drive the bullet deeper. There are good reasons why the .243 remains at the top of the heap; it is nothing more and nothing less than the .308 Winchester necked down to hold .243-inch diameter bullets. If the area this mass is concentrated is smaller (smaller caliber) than the bullet will penetrate deeper because it is encountering less surface area of resistance.

A lot of different variables go into calculating a bullets BC but it, along with velocity, are big factors in the how the bullets trajectory and wind drift behave. With the long-range trajectory, we see the same trends as with the short range, especially at the 300 and 400-yard range. What exactly are we looking at when comparing the 6mm Creedmoor and .243 Win cartridges? She shot two deer this year with a borrowed 243. They are slightly different in weight and in their BC, but it was the closest two we could get. And it is useful, but we think so much of accuracy relies on pairing the right rifle with the right round and have both of them in experienced and practiced hands. While there are flatter and steeper rounds for the .243 Win, just looking between cartridges we do not see a significant difference in bullet drop within 300 yards of these two cartridges. This cartridge is new to the shooting world, but it has been winning target competitions and bringing down animals at a high rate since its inception. A basic review of the rifle you see featured in the majority of my videos. Not only for other ballistic properties but also in terminal performance on impact of the target. If you have two cartridges with similar specs, such as the 6mm Creedmoor vs the .243 Win, you can expect to see pretty similar sectional densities. Looking for previous installments of our "Head to Head" series? We do recommend digging into the BC and how it is derived. And look, you take a guy who has been shooting a .243 Win for thirty years and he is going to prove a lot of new guys touting their 6mm Creedmoor wrong. Especially given how it’s trajectory looked, it could be a unique hunting cartridge.
