243 winchester vs 270

From a standpoint of brevity and clarity, adding more rounds to graph and discuss would really muddle everything up and make the article difficult to move through. The other major question is if this substantial difference in the ballistic coefficients is still seen when we only examine the .243 rounds that are heavier than the 60grain and lighter rounds and are more comparable to the .270 Win rounds. To be more secure in saying that the .270 Win rounds are going have higher BCs, we really need to look at more samples which we have done below and also see how the rounds compare when we are not including the sub 60grain .243 rounds. Finally, we also want to point out that we are using computer-generated data. From a ballistic coefficient standpoint, a 0.1 difference is quite dramatic. We should also briefly discuss the light .243 Win rounds. For the .270 cartridge, it’s hard to beat the Federal Vital-Shok Nosler Partition 150gr round for deer and other medium sized game. We will take a look at the limits of supersonic flight between these two cartridges shortly. The balance of light recoil and versatility as both a varmint and big game cartridge quickly led to the .243 being one of the most popular rifle chamberings in the world. Both cartridges were introduced in the 1950s. Higher velocity, paired with the correct twist rate in your barrel, makes the bullets less susceptible to environmental influences which can make calculating long range shots in windy conditions less difficult. Receive our newsletter with the best articles covering guides, guns & gear. For factory loads of these two cartridges, there were certainly more options for higher BCs with the .270 Win rounds, but for average use on the range, the other ballistic specs, especially when looking at individual rounds, didn’t show distinct differences between these two cartridges. While computer-generated data has its drawbacks, it can still be incredibly useful and informative. Besides ballistic properties, recoil is also another consideration for range shooting. You do see better penetration potential for the .270 Win based on its sectional density and momentum numbers. We have also extended the range out to a 700 and a 1,000 yard marker for those who like to test the limits of shooting factory loads. Of course, if you’re shooting targets, it doesn’t matter. For these reasons, we felt it was important to take a look at the recoil produced by these two cartridges. Calculations were corrected to standard temperature (59F/15C) and pressure (29.92 inHg/1013 mbar) … They also bled velocity at a lower rate than the .243 Win though we also noted that the sub-60grain .243 Win rounds had a hand it that distinction. For more detailed ballistics information please refer to the exact round in question or contact the manufacturer for the pertinent information. Now, determining if that range is significant and should be a big factor in your decision is up to you. We will make it clear what these variables are as we move through the article. And we are just talking about the .243 against the .270. First, the two cartridges are very similar in size and use a rimless bottlenecked case. While there are higher priced rounds for each cartridge, the .270 is a few dollars more expensive for a box than .243 ammunition. In this article, we are going to look at several of the most popular factory loads for each of these cartridges. Cons: Lengthy action and heavier gun. The 243 Winchester versus 7mm-08 Remington race is won by the 243, but not by much. We will be the first ones to admit that nothing compares to hard field data, but the truth is, a lot of us just don’t have the time and/or resources to compile that amount of data. Whether you hunt or participate in distance shooting or a little of both, you know that velocity is a key factor in a bullets effectiveness. This flinching is a huge contributor to missed shots early in one’s shooting and hunting journey. There are dozens of .243 factory loads, in a wide variety of bullet weights and prices, from every ammunition manufacturer and .243 ammo is available wherever game is hunted. Our picks do not mean that we think other rounds do not deserve to be a part of the discussion. We gathered all of the BCs for our selected rounds from the manufacturer and have presented them here in graph form (Graph 4). They go back and forth on what’s better between a .270 Winchester, a 308 Winchester and a 30-06 Springfield. So, if you’re planning on using a factory load for these extreme, top level marksmen distances, the supersonic limit is an important factor. By Chuck Hawks. Averages might have given us an idea of which cartridge has more rounds with better performance in velocity or trajectory, but when getting down to specific rounds, both cartridges had options that would get the job done on the range. Like many cartridges, .223 Remington ammunitionhas its heritage in the military. A lot of shooters might have never heard of the term while others give it a lot of credence when selecting a round. BALLISTIC ANALYSIS. For every action there is an equal and opposite reaction; that is one of the physical laws of our universe. The way the lighter rounds bleed off velocity, the average is really only affected at the earlier yard markers. I would recommend 100 grain + in weight if you want put a big hog down. For those looking to drive nails at long distances on the range or hunters who typically find themselves in wide open spaces where longer shots are needed, this trajectory might be more relevant to your situation. In the grand scheme of things, we don’t think there is enough of a difference to make a decision strictly off of short-range trajectory. By looking at the sectional density (SD) of the rounds, we can get an idea of how well these different bullets can penetrate and gives us a basis for comparison. The .270 takes elk size game every year and there are also those who don’t hesitate to use it for moose, though historically, most prefer to go with larger calibers. A lot of shooters get a little overboard with velocity. When comparing two cartridges, the topic of kick or recoil is bound to come up in the argument. For medium game within 300 yards, both of these cartridges carry enough kinetic energy to cause damage. The .270 is about as versatile as you can get, second only to a .30-06.

While most shooters would be able to handle the .270 rounds fairly easily, especially with a little practice, we do think it is much easier to place several consecutive shots in quick succession on target with the .243. While the amount of energy carried by the bullet downrange is only small part of the equation for stopping power, it is without a critical component. Foundry Outdoors is your trusted home for buying archery, camping, fishing, hunting, shooting sports, and outdoor gear online. We just like it. As we would assume from these differences, the .270 can hold a good deal more powder than the .243 which is needed to bring the heavier bullets up to a proper speed for shooting purposes. For bigger game that might have thick hide and thick bones, you want a bullet with higher momentum to drive through and allow proper wound creation and a clean pass through. Get our PDF with 13 pistol & rifle targets (worth $48) including expert instructions for FREE! The .243 Winchester is simply the .308 Winchester necked down to hold .243″ diameter bullets. While neither of these rounds are near the top of the list for long distance shooting, it doesn’t mean they can’t be a lot of fun throwing lead at the shooting range. While you are going to be able to tell a difference in shooting these two cartridges, the .270 Win still produces a little under 20ft.lbs of recoil. There are a couple of .243 rounds that break the 1000 yard mark but there are far more .270 rounds in this range including a few that exceed 1,300 yards of supersonic flight. Let’s take a look at the short range trajectory of these two cartridges when we include some more rounds. There are going to be some situations where both can be effective cartridges and personal preference might be the deciding factor. There is a lot of overlap between the performance of these cartridges and also categories where there are clear differences. With their speed and shape, these rounds are not going to only penetrate half an inch or bounce off the target. Both the .270 and 7mm mag. Basically, the .308 Winchester round is simply a civilian version of the 7.62x51mm NATO round, which was originally developed for the M14 rifle. The .308 entered the scene in 1952 as a military service cartridge. The .223 Rem. And as we always try to harp on for all of these articles is that you are not limited to using one cartridge the rest of your life. are great cartridges, but which one is better? While it’s your decision, we don’t think it’s enough of a difference to pick one over the other, and the decision should lie with the cartridges performance and how it matches with your situation. Below we have listed five popular hunting and target rounds for each cartridge. And even that last part has been and is still debated. Right out of the muzzle, the .270 rounds have nearly 1,000 extra ft.lbs of force on the .243 round. The .308—a fine design in and of itself—has been responsible for a number of successful cartridges, but the .243 has to be the most successful. This means that the momentum of a rifle's reaction will exactly equal the momentum of the bullet and powder gasses ejected from the barrel. 6.5 Creedmoor vs 243 Winchester Review & Comparison. Velocity, ballistic coefficient, and trajectory all play a major role in how accurate and how well the bullet will bring down game. vs. .243 Win. We are still using a 7lb firearm, and we have selected a common powder load that is kept constant for each round within each cartridge and was selected from the average weights of the bullets for each cartridge. The following is a list of the six best .243 rifles that are currently on the market. If you get the chance, get some experience with both and greatly widen your hunting and shooting opportunities. This is the same type of trend that we saw when looking at the velocity of these two cartridges as well.

Of course, this is only looking at two rounds; we will take a look at a broader selection of our ten rounds for comparison. With the smaller diameter of the .243 rounds, even the 95 and 100gr bullets have a similar sectional density to the heavier 130gr .270 rounds. There are two 130gr .270 rounds with a less pronounced drop, and by that, we only mean a couple of inches, but a couple of inches at 400 yards is pretty significant. Before we dive into looking at the ten selected rounds, we wanted to provide a broad look at thee cartridges trajectory that is a bit less muddled than looking at ten rounds at once (Graph 5). In the simplest of terms, the ballistic coefficient is derived from an equation using several bullets and cartridge variables. We aren’t saying it’s the absolute best round and all others fall before its greatness. The .243 Winchester (6×52mm) is a popular sporting rifle cartridge. And while the lightweight .243 rounds do bring down the average slightly, it’s not really impacting the interpretation of how these two cartridges compare to one another. And given that, it’s quite possible that the lightweight .243 Win rounds are skewing this data. For most experienced hunters and shooters, recoil takes more of a backseat to other performance specs, but it is still a category to consider and discuss. Generally speaking, the higher the muzzle energy, the higher the stopping power. And even though the majority of the .243 Win rounds fall below supersonic speeds before reaching 1,000 yards, the reality is that with factory loads, this is the extreme range of the rounds anyway. Obviously, the .270 is a larger caliber than the .243 and the overall cartridge length for the .270 is nearly slightly over a ½” longer than the .243. The .243 is a great varmint cartridge, but the down side is that they tend to erode barrel throats very quickly. At 300 yards, the average fps falls to 2,307fps, right at the same velocity of the .270 Win rounds. While 1,000 yard shots with these factory loads might be out of the question, both still have the performance for long range shooting in the 500+ yard range. And yes, we know and are fully aware that handloading your own brass can impact the ballistic and other performance properties that we will outline below. The .270 Win rounds all produce recoil energy over 17ft.lb while none of the .243 Win rounds reach over 12ft.lb. Both of these cartridges are popular in the hunting world for a reason. As is the case with any cartridge comparison, less recoil often means a tradeoff with other ballistic categories which we will investigate next. For the .243 rounds we have covered, the Hornady Superformance Varmint V-Max 58gr are great for a day on the range. While the .243 Winchester has a long history of use as a great mild recoiling deer hunting cartridge, the 6.5 Creedmoor is much newer to the hunting game. We have yet to come across any type of guideline for how much momentum is needed for certain game, so this comparison really is just to show any differences between the two cartridges. You’re going to get penetration, but does one cartridge have the higher potential penetration? With more rounds added to the analysis, we still see the same trend of the .270 Win carrying more bullet momentum than the .243 Win. All of the categories that we looked at such as kinetic energy, sectional density, and bullet momentum showed a clear distinction between these two cartridges.
