Will you be reloading? The parent case of the .243 is the other cartridge of discussion in this article, the .308. 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. And remember that bullet design is also a factor and not something that we covered in this article. Momentum simply describes the ability of an object in motion to stay in motion. The 243 and 22-250 with most coyote suitable bullets compare quite favorably. 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. Mag.• .30-06 Springfield vs. .270 Winchester• 6.5 Creedmoor vs. 7mm-08 Remington• 8x57 Mauser vs. .318 Westley Richards• .358 Winchester vs. .350 Remington Magnum• .22-250 Remington vs. .220 Swift• .270 Winchester vs. .270 WSM• .26 Nosler vs. 6.5-300 Weatherby Magnum• .458 Win. And it will be interesting to see how the 6mm Creedmoor fairs in this category. If we look at hunting, the low recoil again is an advantage. There are important exceptions, though, for coyote hunters. For the .243, we are big advocates of the Federal Vital-Shok Nosler Ballistic Tip 95gr. To add to the list of options coleslaw mentioned, I'd recommend a .300 Ham'r from Wilson Combat. Prior to the 1950s the most successful American 6mm/.243-inch cartridge was the 6mm Lee Navy. Not only for other ballistic properties but also in terminal performance on impact of the target. Without much momentum, you might only get a shallow wound which might drop the animal, but it could mean a long day of tracking. Shoot 6.5 Creedmoor and you won't be accused of being overgunned for elk, but with precise shot placement, you can get the job done.I included #19 and #20 just so I could claim 20 reasons to shoot 6.5 Creedmoor. With the 6mm Creedmoor being such a new round, there is still a lot of experimenting going on in the shooting world with this cartridge. Below are the averages for several yard markers for the 6mm Creedmoor rounds as well as the full complement of .243 rounds (20 rounds). These are recoil levels that generally will not be daunting for even neophyte, small statured, or recoil sensitive shooters. All of these categories including the categories outside of ballistics all go hand in hand and influence each other. 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. Of course, depending on what you’re doing with these rounds, the flat trajectory might not make up for what they lack in stopping power. As we move downrange, we are going to omit the 55 and 58gr .243 Win rounds just because they lose energy as they move downrange. Let’s illustrate this quickly. 243 Win vs 6mm Creedmoor vs 6mm Rem; Download our Android App! We also see the light weight .243 rounds drop pretty significantly which we will discuss further. As far as how these two cartridges compare in price, it matters which two rounds you are comparing. Aug 13, 2007 4,330 903 South West, MI . Receive our newsletter with the best articles covering guides, guns & gear. 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. Check Prices . What we are going to look at is the actual energy that is generated from firing these rounds. More importantly, this round maintains the velocities to cause sufficient penetration and expansion, and it carries more than enough stopping power out to 300 yards which is excellent for a .243 hunting round at this weight. I do not think you know what a “long action” is. While this excellent cartridge was almost doomed at birth, it has hung on, to the chagrin of deer, prairie goats, coyotes, and rock chucks everywhere. Handloading, both of them can become competition cartridges as well. as that is the true measure of fair ballistics comparison? 6. With two decades of chasing all manner of upland game, hooved mammals, strutting gobblers, and any small game that can fit in his Dutch oven, he hopes to offer new ideas and viewpoints on hunting and firearm concepts and traditions. There is still a part missing to this story though, especially for those in the hunting realm. That said, I feel it will be some time until the .243 Winchester is unseated, especially among hunters. For that answer, we look at stopping power. 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. 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. We did this to take a step back before everything gets crowded to look at how the trajectories match up to each other (Graph 4). 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. It’s pretty clear from these numbers that there is a trend between these two cartridge types and their BCs. It’s got an old school vs new punk type feel to it. The recoil energies are generated by inputting the rounds bullet weight and muzzle velocity as well as the powder charge and gun weight. Finally, before you jump into the comparisons, we want to make clear where this data is coming from. Instead of looking to determine which cartridge is the best, which seems like an incredibly arrogant thing to do, we are going to look at numerous ballistic and performance data of these two cartridges and draw some conclusions to help all of us better understand which situations one cartridge might be better suited than the other. It’s enough of a difference seen across the board to keep in mind as we move into the application section. We don’t have any concerns with that. Best Home Defense Shotgun [Editor’s Top 8], A Glossary For Firearms: All Terms and Gun Lingo Explained, Crimson Trace Laser Grips Review [Hands on], Ruger Scout Rifle Review [Hands on with photos], Best 9mm Ammo in 2021 [Self-Defense & Target], 6.5 Creedmoor vs .243 Win – Cartridge Comparison, .243 Win vs .270 Win – Cartridge Comparison, 6mm Creedmoor Hornady ELD-X Precision Hunter 103gr, 6mm Creedmoor Hornady V-MAX Varmint Express 87gr, 243 Hornady Superformance Varmint V-Max 58gr, 243 Federal Vital-Shok Nosler Ballistic Tip 95gr, Federal Vital-Shok Nosler Ballistic Tip 95r, Winchester Power Max Bonded Protected HP 100gr. The 243 … Using 55gr NBTs the 6mm Creedmoor will outperform the 22 Creedmoor … Maybe after looking at the data, we can see if the 6mm Creedmoor might bring something extra to the table. We also saw a pretty significant difference in the ballistic coefficients of these rounds. For hunting, it’s also an intriguing round that has a lot of potential. My buddy John Snow—now editor of Outdoor Life—was writing an article about the pleasures and pitfalls of developing his own cartridge. We will also examine the sectional densities and bullet momentum for each round we have selected to represent both cartridges to determine the amount of potential penetration. You can throw those two out if you want. You'd have to take about the same lead for wind drift into account for both, but the 243 has slightly more margin for error. The same trend happens at the 300-yard mark. Precision, wrote the piece on his necked down 6.5 Creedmoor, and moved on. 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. vs. .300 Win. It’s true that the 55 and 58 grain .243 rounds have a lot more velocity than all the other rounds, not just the 6mm Creedmoor rounds. Like its father, the .243 Winchester is an efficient cartridge, and will give good velocities without being too hard on barrels. While the mass is being focused on the same area for both bullets, the greater weight of bullet C should drive the bullet deeper. The .243 Win has been in use for decades and has a wide base that uses it for a lot of hunting purposes. Friday, February 22, 2019. It is fine with me if you like the Creedmore cartridges better. There is no comparison with the 243 in daylight hours. Making no remarks about others comments. Even in the hands of a capable marksman, the groupings can change from day to day whether it was due to different environmental conditions or if he/she just had a baby up all night crying. With a degree in Microbiology and several years of doctoral work manipulating bacterial genes, he attempts to merge the rational and unbiased thinking of scientific research with the passions of hunting and fishing. This is all from just going off numbers which is only half the story. The rounds from both cartridges tend to hang around the 8.5-12 ft.lb energy range. When looking at the 6mm Creedmoor vs .243, we are looking at two cartridges that come with the advantage of having light recoil. Take bullet A at 150grains with a bullet diameter of .2″ and bullet B at 150grains with a bullet diameter of .15″. Both use the same 6mm/.243” diameter bullets, but the 6mm Creedmoor was specifically designed to use longer, heavier, and more aerodynamic projectiles. Recoil, when severe enough, can easily throw off a shot. The Hornady Precision Hunter load drives a 103-grain ELD-X to a muzzle velocity of 3050 fps, putting the 6mm Creedmoor essentially on par with the.243 Winchester, but it’s the ability to properly seat the longer bullets with the best ballistic coefficients that gives the 6mm Creedmoor the edge out beyond 500 yards. No other environmental variables were used. 6.5 Grendel. It’s also important to recall how the 6mm Creedmoor rounds showed the trend of maintaining velocity, which also led to better trajectory, once you got out to the 300+ ranges. Either way, all of the heavier rounds only showed between 9.6 to 12 inches of bullet drop at 300 yards, which is more than manageable. Before we get started, I have an administrative note: Some of the links below are affiliate links. With both of thee cartridges taking a .243 caliber bullet the difference is going to depend on the bullet weight. Today, the 6mm is showing that it may be even better-suited to shooting tiny groups at 1,000 yards. It’s tough to look at the averages between these rounds because of the light varmint rounds for the .243 Win rounds just as the case was in the previous rounds. I have and shoot a .243, 6x47 lapua, and 6.5 creedmoor. We can switch it up with different bullet mass as well. Recoil really comes into play when we are talking about more recoil sensitive people such as inexperienced users. If you look anywhere on the internet concerning cartridge comparisons and especially how they compare to stopping power, you are going to find some pretty heated arguments on which bullet characteristic best equates to the amount of stopping power. However, having been with us since 1955, the .243 Winchester is a very effective hunting cartridge, especially inside of 500 yards, and when used on game animals of suitable size and build. You will often find a lot of people fixated on the velocity of the bullet, and while velocity is important, they often lose sight of why it is. A good friend will help you move a body. From the 300 yard mark to the 500-yard mark, the trend flips and the 6mm Creedmoor rounds only lose around 500 fps while the .243 rounds lose on average 800 fps. We hope that articles such as this one help you take a more broad look at how two cartridges compare to one another. 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. When we take those two rounds out, the averages are almost identical between the 6mm Creedmoor and .243 Win rounds. Some rounds even shoot differently out of different rifles. A lot of this difference has to do with the bullet design used by the 6mm Creedmoor which makes them more aerodynamic. Get the American Hunter Insider newsletter for at-a-glance access to industry news, gear, gun reviews, videos and more—delivered directly to your Inbox. 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. Even 400 yards they can still bring them down with the proper shot placement. We gathered the bullet energy data from the manufacturers and graphed them over a range of 500 yards (Graph 7). Both have applications in the shooting and hunting world, and both are going to overlap a lot in those applications. Being a gun enthusiast can be a lot of fun. In my opinion, coyote rifles and long range rifles are two different animals.-----A friend will help you move. So naturally, we had to take a look at the long-range trajectories of these two cartridges to see how they stack up against each other. Including younger generations just getting into the sport. We have gathered the velocity data from the manufacturers and have graphed them here over a 500-yard range (Graph 2). At this particular moment, you don’t have many options when it comes to factory loads. So, we have generated the recoil energies from these two cartridges using an online ballistics calculator (Graph 1). As the bullets move out to the 200-yard range, we do see a slight difference between the cartridges when taking all of the rounds into account. At first the trend was to 7mm, then to 6.5s — like the 6.5 Creedmoor, .260 Rem. .22-250 Remington. We kept the rifle weight the same for all rounds. 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. Quite a few target shooters tried the .243 Winchester during the rush to smaller calibers, including David Tubb, 11-time national High Power champion. A lot of other factors go into felt recoil, including gun design, so it’s not very quantifiable. Below are the averages for the 6mm Creedmoor vs the .243 Win when we include the extra fifteen rounds for the .243 cartridge. Too much velocity with an incorrect twist rate or a certain bullet design and you can get an unstable flight with leads to inaccuracy. Popular manufacturers of the .222 Remington in a Predator/Varmint … Where ballistic calculators are used we kept as many variables the same between rounds of the same cartridge. The 6mm Creedmoor vs .243 is a very interesting comparison. Long story short, John built a couple of rifles for the project, with the help of George Gardner of G.A. It’s not quite the same as the actual felt recoil that you feel, but increased recoil energy does correlate with increased felt recoil. In that case, it is going to depend on the design of the bullet and other properties. Ps. I wonder if the .243 Win. A std 243 factory rifle mostly won’t have enough twist to shoot those projectiles so your straight away looking at rebarreling a factory 243 or building a custom rifle. The reason is the smaller diameter. In this article, I’m going to do a detailed comparison of the 6.5 Creedmoor vs 243 Winchester and discuss the pros and cons of each one to help provide some insight into which cartridge will work best for you. 6mm Creedmoor vs 243. It’s tough when trying to compare two different rounds of the same cartridge. They both take the same caliber bullet and have nearly identical neck and base diameters. Regarding availability, there is no doubt that you are going to run across a lot more .243 Win cartridges than you will 6mm Creedmoor rounds when it comes to factory loads. (bartlein barrels (medium palma contour) nightforce scopes and AICS or McMillan stocks) Here is my take. The 6mm Creedmoor—in the same fashion of its larger counterpart—fits those bullets very well. I converted to a tikka 243 for daytime. Each rifle tends to have its own small differences in its profile, and this means some small differences in the ballistic output. Take a look at any good ballistics program—Hornady and Federal both have an easy-to-use program on their websites—and you’ll see the advantage of the better B.C. By now plenty of you are ready to slap me upside the head and extoll the superior virtues of your 243 Winchester, 6mm Remington, 6mm Creedmoor, 25-06 Remington, 257 Wby., 17 Remington or even your big 300 Win. While there’s no replacement for displacement BUT there is a replacement for BC. We also see that all eight of these rounds maintain supersonic speeds out to the 500-yard mark. The ,243 is a great round and there’s not enough of a difference for most people to think of converting, but your statement isn’t on the nose. 2 more inches of barrel may add another 50 fps regardless of whether it’s a 243 or a 6CM. It maintains velocity very well and shoots incredibly flat. As you can see, we are only comparing a limited number of different rounds for each cartridge. When it comes to this type of data, we don’t have any concern with comparing cartridges, but you should be aware that these numbers can change when being fired from your rifle. 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. This cartridge provides incredible trajectories with only 3″ of bullet drop at 200 yards. We like to look at the trajectory at these ranges because it is most often the distance hunters in most applications sight in their optics. The trajectory is one of the most discussed ballistic properties when it comes to discussing the performance between different rounds as well as between two different cartridges. 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. If the long-range shooting craze hasn’t possessed your soul, but you still want a cartridge that will shoot flat and hit hard, there are no flies on a .243 Win. arrived on the scene in 1952, it prompted gun writer Warren Page to … It brings a lot of energy to the table with over 1,000 ft.lb even at 500 yards. When comparing two cartridges that are often used in the hunting world, we like to look at short range trajectories with the optics sited in at 100 yards. From 500 to 700 yards, we do start to see the 6mm Creedmoor rounds separate themselves from the rest of the pack regarding flatness. The 6mm rounds have an average bullet drop of 11,” and the .243 Win rounds have an average of 11.6″. Another trend that we see in this graph is the rate that the bullets from each cartridge bleed velocity. The first rifle I ever got was chambered in. If you hit them behind the diaphragm, they can still keep breathing, but 243 caiber bullets have a lot of punch. And of course, we just don’t have the opportunity to include more 6mm CM rounds at this time, but hopefully, soon we will have this list expanded. Let’s be honest with ourselves for a moment, most of us can deal with recoil, it’s no big deal, but isn’t shooting much easier when dealing with lighter recoil? Mr. Gardner was playing with the creation a couple years later, and it proved to be a fantastic choice for the PRS competition; needless to say, it caught on and is now available in factory form. All bullets, once fired, carry kinetic energy that is generated by the force of the gunpowder being ignited and the weight of the bullet. If you are competing or shooting past 500 yds, then they are good choices, and getting a custom barrel is just part of playing the game. At these ranges, the trajectory is not the issue as much as stopping power, which we will look at shortly. Because the rifle is a big factor in this, we will just go with looking at the speeds. All are set up for long range shooting. 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. That is my choice, (but I don't own a 6.5) the 223 and the 243 are not similar caliburs, the 243 is way more gun. and 6.5-284. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. On impact, this kinetic energy is transferred to the target where it causes damage to surrounding tissue and organs. The two cartridges are very similar in a lot of aspects. The question I would ask is why are you choosing those projectiles? I have buddies that use 6.5 Grendel on hogs and I think they'd be great for deer. I mean slight differences in catridge base to neck measurements im sure but to me, they are practically the same round. The shooting world is too big to just limit yourself to one cartridge, and we go into these articles with that in mind. Necking down of the 6.5 CM allowed the base to be fitted with a .243 cal bullet and allowed a lower recoil producing round. I agree with Mark. And while that is nice, the make or break for hunting cartridges is the stopping power. We calculated the sectional densities for all of our selected rounds and graphed them below (Graph 8). There have been military developments, as in the 6mm Lee Navy (father of the .220 Swift), but the post-WWII era saw some very fine designs; 1955 alone saw three important 6mm cartridges. My favorite bullet in 6mm is the Sierra 80g Blitz bt, it is awesome to say the least, provides the loudest PLOP of any bullet I have ever shot...no kidding. The sectional density of bullet B is going to be slightly higher than bullet A. There are several other manufacturers such as Remington and Federal that have introduced 6mm rounds in their 2018 line, but the data is still not there. This is a key section when it comes to determining which situations each cartridge might be better suited for than the other. If you’re looking to choose between one of these cartridges, it’s going to be a wash when it comes to recoil. There are a lot of guy's who use .243 for coyotes. That’s a pretty simple way of illustrating that concept, but we think it gets the idea across. 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. Since I will be reloading for which ever one I decide to get, I would probably load these .243/6mm bullets, 107gr. The 6mm Creedmoor has two rounds at .512 and .536 while the .243 Win rounds do not crack the .4 mark. With that, we will try to bring all of this information together when we get to the application section. From the muzzle out to 200 yards, the .243 rounds have about 100 fps more velocity than the 6mm Creedmoor rounds. If anyone has any opinions on loads for coyotes in 6.5 creedmoor and/or the aforementioned rounds, I'd love to hear what you have to say. 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. Coyotes have a will to live that is simply unreal. 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. A hunter who has a good .243 will be able to handle the deer species, including mule deer, as there are a good number of premium bullets available in both factory loaded and component form. I’d left the reamer in a toolbox and the dies were sitting on a shelf in my house, literally gathering dust,” he says. Like we mentioned earlier, there are some more 6mm Creedmoor factory loads coming onto the scene this year, but you’re still really limited if you aren’t hand loading. It's a good round that delivers a little more down range energy than a 22-250. You could have used hand loads with the exact bullets loaded to the same pressures and compared the performance potential of the cartridges to each other. We don’t want to look at the averages just because the lightweight .243 rounds really bring it down; lighter bullets are much more susceptible to environmental factors such as wind drift. Looking for previous installments of our "Head to Head" series? To determine the powder charge, we used Nosler load data and went conservative with the grain weight since we are dealing with factory loads. And by flat we mean there is a less pronounced drop in elevation over time. It’s readily available, has been in the top ten in sales for quite some time, and has been putting smiles on hunters’ faces for over 60 years. I have bought 3 243’s in the last 5 years and none are a long action…, All pre ’64 winchester are long action . Of course, we would only take lighter recoil as long as we got the ballistic and terminal performances we wanted. Therefore, if you want to try to load the higher BC bullets designed for the 6mm Creedmoor then you will have to have the bullets seated deep into the brass which will cut into your powder capacity. There are some key differences between the two modern cases. Which ever cartridge launched these three bullets the fastest would also have the fastest maintained velocity at the far ranges. So we’ll take a stab at accuracy for the sake of argument and a little fun. It’s also important to note that these are all factory rounds and they are not going to have the performance of hot hand loaded rounds that you might come across on other sites or forums. It seems like the internet is inbetween a Hornady 95g V-max and Hornady 143g ELD-x precision Hunter. match grade bullet with a BC of over 0.5. It’s significantly lighter for both cartridges compared to other centerfire rifles often seen used for medium sized game. 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. The ELD-X are great controlled expansion bullets that can penetrate and pass off a large percentage of its kinetic energy. HPBT Matchking ( Sierra ) – .527 BC 105gr. The lightweight .243 rounds outperformed all of the rounds at this range with between 2-12” flatter trajectory. There is a fine line with the velocity of the bullet. Niles Coyote Gunny Sergeant. For the 6mm Creedmoor, we like the Hornady ELD-X Precision Hunter 103gr round. The lightweight .243 rounds shoot just as flat, but they also weigh about 50 grains less. “I was scratching my head and thought the 6 Creedmoor might work. That paired with its BC makes it a great cartridge for adverse weather conditions in the field. Of the three, the H&H never really had a chance here in the U.S., and the .244 Remington was introduced with a twist rate that prevented it from using the heavier 100- and 105-grain bullets that the .243 Win.
