243 vs 6mm creedmoor barrel life

As a general rule, you want at a minimum of 1,000 ft.lb force when trying to take down game around the whitetail size range, and more around the 1,500 to 2,000ft,lb range when talking about bear, elk, and moose, but you don’t usually go after that size game with these cartridges. The parent case of the .243 is the other cartridge of discussion in this article, the .308. The Hornady 6mm ARC takes the 24-caliber into record territory — the slowest muzzle velocity of any commercial cartridge propelling .243” bullets. Shot placement is equally if not more important than the amount of energy that the bullet is carrying. The Rem has a slightly higher velocity typically. So, we have generated the recoil energies from these two cartridges using an online ballistics calculator (Graph 1). that people are getting 2500-3000 rounds from 6mm Creedmoor barrels, while 800-1500 or so seems to be the expected life of a 243 AI barrel. It began life several years ago as a wildcat and quickly began to rival its parent in popularity among log-distance competitors. With that, we will try to bring all of this information together when we get to the application section. All bullets, once fired, carry kinetic energy that is generated by the force of the gunpowder being ignited and the weight of the bullet. Hornady 6mm ARC Losing Ground. vs. .300 WSM• .223 Remington vs. .22-250 Remington, E-mail your comments/questions about this site to: EmediaHunter@nrahq.org, For questions/comments about American Hunter magazine, please e-mail:Publications@nrahq.org, You can contact the NRA via phone at: NRA Member Programs1-800-672-3888, To advertise on American Hunter, visit nramediakit.com for more information. The 22 Creedmoor is a wildcat caliber you get by necking down a 6.5mm Creedmoor to .22 cal. The velocity as well as the design of the bullet factor in as well. Since we are discussing two rounds that are popular for target shooting and one of them being hailed by some as the next great match cartridge, we should probably look into how they compare in their BC’s. I seem to recall reading (on the GAPrecision site?) You will use slightly less powder with the 6mm Creedmoor but not enough to make a big difference. It’s not just the lightweight .243 rounds, but several of the heavier rounds as well. There are so many variables that go into how well a bullet is going to take a game animal. When we talk about trajectory, we are only referring to elevation and how much a bullet will drop as it moves downrange. ... Ohio in 2007 and discussed the popularity of 6mm wildcat cartridges. The velocity of the bullet plays a critical role in several other performance categories. Just thinking 6x47 Lapua vs 243 vs 243 AI in terms of barrel life. Accuracy is always a tough topic to broach when trying to compare two different cartridges. It can get pretty heated, but that’s just the passion this sport brings out and most of the time it’s all in good fun. For their sized game such as coyotes or other varmints, they carry enough energy at any point in their range. The modern/improved design of the 6XC also allows you to use 7 grains less powder to achieve the same muzzle velocity as the 243. All of these categories including the categories outside of ballistics all go hand in hand and influence each other. The heavier 6mm CM rounds do seem to carry significantly more momentum than the other rounds in this list throughout the entire range ranging from 2 to 5 more ft/f.s from the muzzle out to 500 yards. It’s an even smaller margin if we don’t take the lightweight varmint rounds of the .243. The Creedmoor seems to have the fastest barrel twist rates (1:8 and 1:7.5) which is why it typically is … That said, I feel it will be some time until the .243 Winchester is unseated, especially among hunters. The large majority of rounds fired through this rifle were the Sin City Precision team load. This data, paired with the sectional density results, points towards the heavier 6mm CM rounds having more potential for deep penetration. Some precision shooters make claims to barrel life can be a difference. To determine the powder charge, we used Nosler load data and went conservative with the grain weight since we are dealing with factory loads. At this particular moment, you don’t have many options when it comes to factory loads. Nothing to base a decision on. The vast majority of factory loads for the .243 are more oriented towards hunting. While all of these rounds will not be graphed and discussed, the averages will back up that our selected rounds still give an accurate reading of how the two cartridges are similar and different from each other. 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. I was thinking of buying my 14 year old granddaughter a deer hunting rifle. vs. .458 Lott• 7mm Rem.

My best with it has been a 5-shot.38 MOA @200 yards. Not exactly something you’d want to hump around all day long. Of course, bullet design (including sectional density) and expansion also influence a rounds ability to penetrate. And overall, we see that these rounds from both cartridges have incredibly low recoil compared to say the .30-06 or .308 cartridges which sport recoil energies in the 20-25 ft.lb range. FWIW we got about 2,000 rounds on our last 6 Creed barrel, at 1800 rounds it was still shooting 1/3 MOA 5-shot groups at 300 yards. Receive our newsletter with the best articles covering guides, guns & gear. Looking for previous installments of our "Head to Head" series? The barrel life of a 6.5 is a little better than a 6 but neither are anything like a .308. The 6mm CM had two rounds greater than .5 while none of the .243 rounds cracked the .4 mark. We have both a 6 and 6.5 Creedmoor in custom actions in chassis setups. Almost like the .260 vs 6.5 Creedmoor debate. A bullet with a higher sectional density should have greater penetration than a bullet with a lower SD. Like all of the other categories we have looked at, the lightweight .243 rounds tend to throw off the comparison slightly when looking at averages, but we like having them to show the versatility of the .243 Win cartridge. To compare the performance specs of these cartridges, we have selected several individual rounds from each to examine. With both of thee cartridges taking a .243 caliber bullet the difference is going to depend on the bullet weight. The 6mm Creedmoor vs .243 is a very interesting comparison. 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. The .243 Winchester fires smaller diameter bullets at a significantly higher velocity than the 6.5 Creedmoor. The lightweight .243 rounds have significantly less bullet momentum than the other rounds which we would expect given that mass is a component of momentum. I suspect that Hornady understands this as their 6mm Creedmoor cartridges are only moderately faster than the 6mm ARC. Just a better design! There wouldn’t be many more 6mm hunting cartridges added to the lineup until the 21st century; Remington’s 6BR, and the 6mm PPC certainly made a splash in the target world; the .240 Weatherby is certainly a speed demon, and Winchester added the .243 WSSM to the short/stubby lineup. Thanks. It’s beyond us to try and describe it, but if you’re reading this article, it will interest you. Even with the lightweight .243 rounds, which show the flattest trajectories, the 6mm Creedmoor holds an advantage throughout the entirety of the range, though the differences in the average are less than one inch at the 300 and 400-yard mark with all rounds in play. The sectional density alone does not provide a clear indication of how much penetration the bullet will have. This sub-category is going to cater more towards those looking for a hunting cartridge, but if you’re going to buy a rifle chambered for one of these cartridges, then there is no harm in understanding as much as you can about each. Like our smaller data set, the 6mm Creedmoor rounds tend to maintain velocity better and outperform the .243 rounds downrange. We compare our Eagle Eye Precision Match loadings of each cartridge to help shooters determine which is the best choice for their … Finally, before you jump into the comparisons, we want to make clear where this data is coming from. I would double that. We gathered the data in the same manner as the short range trajectory, except with the zero range set at 200 yards and graphed the bullet loss (inches) out to the 700-yard mark (Graph 6). Long range, the 6mm CM does show a better trajectory than the heavier .243 rounds. When hunting larger game, you often need your round to be able to penetrate through thick skin and tissue to reach vital organs. With the stability in the velocity department and the high BCs, we weren’t surprised at the trajectory data. Shoot it where it wants to shoot. The bullet drop on this round is second to none when it comes to .243 factory loads. The 6mm CM is basically a necked down version of the 6.5 Creedmoor. From 500 to 700 yards, we do start to see the 6mm Creedmoor rounds separate themselves from the rest of the pack regarding flatness. They have incredibly light recoil which is advantageous when you are going to be shooting a lot. I've always been told 243 & especially 243 AI are barrel burners. 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.The 6mm Creedmoor is nearly identical to the 6.5 CM which we have reviewed and compared to the .243 Win in a previous article. As the rounds move downrange, we see the rounds group together based on their cartridge type. Do a 22 BR or 22 BRA. What we are going to look at is the actual energy that is generated from firing these rounds. The .243 rounds have lower bullet energy consistently through the 500-yard mark, and like the velocity, they tend to bleed energy at a higher rate than the 6mm Creedmoor rounds. When i sold my last one it had over 1800 rounds thorugh it and it was still a solid 1/2 MOA rifle. The ballistic coefficient of a round is simply letting you know how well the bullet resists drag and wind drift and thus, the easier it will be to group shots at long range. We see a similar trend when looking at the smaller sample size of the .243 Win rounds compared to our four 6mm CM rounds. That’s not to say there are not .243 rounds with better BCs, but they usually hang in that .25-.45 area. The rounds from both cartridges tend to hang around the 8.5-12 ft.lb energy range. I want to buy a rifle for her in either 6MM or 6.5 Creedmoor. Best 9mm Ammo 2019 [Self-Defense & Target], 6.5 Creedmoor vs .243 Win – Cartridge Comparison, Best .40 S&W Ammo: Self Defense & Target Practice. The 6mm bore diameter has long been relied upon for double duty, serving the deer hunter and varmint/predator hunter equally well. To give you some more depth and widen the selection size, we have compiled the data for an additional fifteen rounds for the .243 Win cartridge and will list the averages for these rounds in several categories. I am going to be shooting a lot more of the 308 Winchester this year, and I kind of touch on it in the latest podcast. The 6mm Creedmoor often uses longer, more aerodynamically stable bullets which is what adds to the slight increase in the overall length of the cartridge compared to the .243 Win. On impact, this kinetic energy is transferred to the target where it causes damage to surrounding tissue and organs. Ballistically, it is also high grade. Not only for other ballistic properties but also in terminal performance on impact of the target. The 6mm Creedmoor cases had an average water capacity of 49.2 grains, and the.243 Winchester cases held 49.6 grains, just about the same. Both have applications in the shooting and hunting world, and both are going to overlap a lot in those applications. While we do see the .243 Win round showing a flatter trajectory, we also have to remember that there is a weight difference between the two rounds. While the .243 has a rich history in the hunting world and is often a young sportsman’s first centerfire rifle, the 6mm Creedmoor has yet to break into that world. The Creedmoor case is a bit shorter than 243 - you can load heavier bullets seated longer with the Creedmoor case and still fit in a 308 magazine. 6mmBR.com is the best guide for 6mm BR Benchrest precision shooting, complete with 6BR FAQ, Reloading Data, Shooter Message Boards, Reader Polls, and Photo Gallery. Sectional density plays a role in momentum as more momentum is conserved when the projectile, a bullet in our case, is striking a smaller area. I seem to recall reading (on the GAPrecision site?) Bullet C is 200grains with a diameter of .2” while bullet B is 150grains with a diameter of .2”. They are slightly different in weight and in their BC, but it was the closest two we could get. I'm assuming barrel life will be pretty short, but any other drawbacks of going with a fast twist 243 running heavy hand loads vs just going with the 6mm creedmoor new hotness?

It is lightweight with very little recoil, so it’s fun to shoot all day with little fatigue. We do have to be cautious when making inferences about these two cartridges from the above numbers because of the novelty of the 6mm Creedmoor case. There are quite a few heavier bullet weights out there for factory loaded .243 Win ammo in the 100-110 grain weight range. With the averages listed at the end most of these sections, you will see that the trends hold true when we bring in a lot more .243 rounds into the equation. The 6mm Creedmoor was introduced specifically for these shooting applications. When we take those two rounds out, the averages are almost identical between the 6mm Creedmoor and .243 Win rounds. The same trend happens at the 300-yard mark. It pretty much limits out with deer regarding large game hunting as we will discuss in this article. Besides the two lightweight .243 rounds, the muzzle velocities of both the 6mm CM and heavier .243 Win rounds was pretty similar going by the averages. Yup pretty much the same ballistically. She shot two deer this year with a borrowed 243. At the 500 yard mark, the 6mm CM rounds show an average of 2.5″ less bullet drop and this gap widens at the 600 and 700-yard mark with an average difference of 7.3 inches and 15.8 inches. The easiest answer is 6.5 Creedmoor. 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. Apr 30, 2015 #3 Jud96 Well-Known Member. It is lightweight and might be more influenced by drag and wind drift if you are looking at shots at 500+ yards. Over the past decade the 6.5 Creedmoor has become among the most popular long range shooting cartridges available. Deeper penetration is not always an indicator of a better round or cartridge. We calculated the sectional densities for all of our selected rounds and graphed them below (Graph 8). We also see that all eight of these rounds maintain supersonic speeds out to the 500-yard mark. At short ranges, there was less than an inch of difference between the two cartridges of similar bullet weights at 200 yards and about half an inch difference in favor of the .243 rounds when we factor in the 55 and 58grain .243 rounds. We gathered the bullet energy data from the manufacturers and graphed them over a range of 500 yards (Graph 7). We have gathered the velocity data from the manufacturers and have graphed them here over a 500-yard range (Graph 2). And it will be interesting to see how the 6mm Creedmoor fairs in this category. I think I want to buy another 243 Remington 700 this spring. Before we get into any of the performance categories for the 6mm Creedmoor versus the .243, we want to take a moment to just look at the similarities and differences between the two cartridges regarding their specifications. But, say for a 6mm round at 2800 - 3000 fps, by comparison, is the 243 Win more prone to barrel burning than, say, the .22 cal varmint rounds like the .22 Swift, 22-250 or the 25-06? Loading at 2900fps vs. 3200fps to extend barrel life is nonsense. Though since I would be ... 243 Win vs 6mm Creedmoor vs 6mm Rem; Download our … You can’t help but wonder what that same guy might be doing if he had been sending a 6mm Creedmoor downrange for the same amount of time. This section is probably going to carry more weight for hunters rather than just competition shooters, but it’s never a bad thing to know as much about a cartridge as you can. Something you might think about is having a practice rifle and a match rifle. Assuming shooting at a reasonable rate with simmilar loads which round will be the easiest on barrels? Higher velocities increase penetration as does highly bonded bullets that will not fragment on impact. At 300 yards, the 6mm Creedmoor had an advantage over the heavier .243 rounds with about 1.3” flatter trajectory on average. There are some key differences between the two modern cases. The old 243 Winchester can beat that by about 300 fps. And that doesn’t mean they aren’t great rounds for what they are designed to do, kill varmints. Necking down of the 6.5 CM allowed the base to be fitted with a .243 cal bullet and allo… There are just so many variables that we think it would be a disservice to you to try and present these two cartridges that way. How OL's wildcat came to dominate long-range precision-rifle shooting The case capacity differs slightly between these two cartridges, but they are not going to be loaded with the max amount of powder, even in hand loads if done by someone who knows what they are doing. The 6mm Creedmoor is nearly identical to the 6.5 CM which we have reviewed and compared to the .243 Win in a previous article. Dense woods for whitetails with shots averaging around 100 yards and you probably don’t care at all what the BC of your round is. Inside of that, it exceeds the general guidelines for bullet energy for whitetail sized game. It’s fairly inexpensive compared to other rounds with similar performance. A lot of other factors go into felt recoil, including gun design, so it’s not very quantifiable. The 6mm Creedmoor, on the other hand, is a much newer and more tailored to a smaller niche in the shooting community and a niche that already has a lot of cartridges flooding the field for the fastest and flattest load.
