Even when we remove the two lightweight .243 Win rounds, the .270 rounds are carrying an average of 17lbs/ft.s of momentum at the muzzle and 13lbs/ft.s more at 500 yards. Coyote and Roe deer is class 1, the 223 for example. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 270 vs 30-06 Debate Settled Once And For All. While lots of hunters have readily adopted the 6.5 Creedmoor for hunting a wide variety of game, many other hunters remain skeptical of the suitability of the new cartridge for big game animals, particularly when its compared to the time tested .25-06 Remington and .270 Winchester cartridges. In less than ideal conditions, the .270 Win had more rounds with higher BCs that can help minimize bullet drift due to wind and the .270 also was not too far behind the .243 when it came to trajectory out to 500 yards, though the average .243 Win was a few inches less. Before we move on to stopping power, let’s take a look at the long range trajectory of these two cartridges with the larger sample size to generate numbers from. 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. Consider the range of your shot as well as the size of the animal. Unlike most of the ballistic properties we have looked as so far, there is a general distinction in stopping power between the .243 and .270 cartridge. 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. Is that by design? Is that by design? The .243 has a slightly flatter arc, but we are only talking about a few inches. The higher the ballistic coefficient, the better the bullet can resist wind drag and wind drift. Some of their performance characteristics might also fit better with some people’s experience and comfort level. There is a tight cluster of the heavier .243 rounds and the heavier .270 rounds around the 22-23” mark at this range. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. As you move out to the 400-yard mark, you will begin to see some distance forming between the rounds. Is that by design? For the rest of the yardage marks, we are going to exclude those two rounds; they are flat, we get it. The higher the velocity, the more penetration and expansion you are apt to get, which is important for hunting purposes. Recoil can throw off a shot, especially for younger or more inexperienced shooters who are thinking about the kick as they squeeze the trigger. Given the bullet’s weight is half of the equation for sectional density, we have to factor in how the sub-60grain .243 Win rounds are affecting these numbers. Dez 2010, 10:11. Or something along those lines. At 300 yards, the average fps falls to 2,307fps, right at the same velocity of the .270 Win rounds. So as for those two options, I would recommend the .243. I noticed that the XP and cash for kills using the .270 are lower than the .243. 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. The .243 and .270 are both class 2. We like the .243, especially the lighter rounds for varmint hunting and small predators. Even so, the velocities of the .243 are enough so that the lower BC’s would not hinder performance at ranges these rounds are used for. So even when just comparing the average and heavier bullet weights of the .243 Win, we still see a significant increase in bullet momentum with the .270 Win rounds. When looking at these rounds that cluster near the center of the graph, we see that there is quite a bit of overlap between the rounds of both cartridges. While the numbers we show can vary by small amounts, we can control for a lot of variables we wouldn’t be able to with field tests. When they are excluded, we see the gap close to where these two cartridges are nearly identical. Given the kinetic energy is generated from the velocity of the rounds as well as the mass of the projectiles, it is not a surprise that the .270 Win outperforms the .243 Win in this case. Overall, we are pretty confident in these numbers and they give you an accurate description of how these two cartridges compare in terms of kinetic energy. Have my own thoughts, have done some searching on ballistics and Max shot would be 200 yards. If you hand load, you could put a little more power into the .270 to help its downrange performance and the same can be said for the .243 Win. Finally, a clean kill means you are not going to have to track a wounded animal sometimes a couple hundred yards and possibly in the dark. The following ammunition cartridge ballistics information and chart can be used to approximately compare .223 Remington vs .243 Winchester ammo rounds. The .270 Winchester was introduced in 1925 where it would stay in relative obscurity for a time. its not about level , you have to take the good gun for the good hunt , example with a deer , if u shot it with a .270 bonus integrity will be bad (bullet hole bigger than a .243) but .270 is better than .243 for bigger animals like moose :). Now, determining if that range is significant and should be a big factor in your decision is up to you. If you get the chance, get some experience with both and greatly widen your hunting and shooting opportunities. The averages do give the slight edge in velocity to the .270 Win when not including the sub 60 grain .243 Win rounds. We see from this graph that there is a very distinct difference of recoil generated from these two cartridges. Both of these cartridges are popular in the hunting world for a reason. Every shot on the front of the deer is just a flesh wound - even with the polymer tip bullets. Both cartridges were introduced in the 1950s. We used an online trajectory calculator to generate the trajectory path, and we selected two rounds, one for each cartridge, which are from the same manufacturer and have the same bullet design. While computer-generated data has its drawbacks, it can still be incredibly useful and informative. A bullet more resistant to these factors is going to be less likely to be pulled off its flight path and theoretically will be a more accurate round. At the end of each section, we will present averages of the larger data sets for each cartridge. if you shoot the deer from the front i found that aiming very low on the front where there is sort of a flap hanging down goes right thru the heart. The .270 has gained a huge following in the world of hunting from small varmints and predators to large American game such as sheep and deer. The .243 is often referred to as the baby brother of the .308 Win. We are looking at the force (ft.lbs) from the muzzle to 500 yards downrange. 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. Das beste Kaliber kannst Du meiner Signatur entnehmen. Bullets that do not expand will penetrate deeply, but not cause as much tissue damage. 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. When comparing cartridges or just researching one, the ballistic coefficients (BC) are going to pop up at some point. The .270 Win is also versatile in its own right and can and is used for the same medium sized game as well as larger animals. At 400 yards, the average increases to 26.1 inches of bullet drop. Like the .243, there is a lot of options regarding bullet weight and design, and they are readily available and affordable. Just glancing at the graph, we can see that there seems to be a trend towards higher BCs for the .270 rounds compared to the .243 rounds.
