I'm Steve. The .257 Bob, as it is affectionately known by its fans, began life as a wildcat but was ⦠Part of the .243âs popularity stems from its light recoil and dual-purpose function for taking varmints and predators as well as deer. By doing this, you get more information, we get a better picture of how these two cartridges compare, and the article will still be easy to navigate through. Just from our selections, you can see that there are some .243 rounds with BCs that stack up a lot better to the .270 rounds. In this Article: Single Action RevolversDouble Action RevolversSo…What Do I Buy?Shooting Both Types Of RevolverLoading For Revolvers â Either StyleSo â What Does All This Mean? And by any comparison to any other legal big game hunting cartridge and caliber, that’s pretty damn light. In general, there is not a huge difference in trajectory when strictly looking at the two different cartridges. Though hot, you will notice that with how light these bullets are and the small ballistic coefficient, which we will get to shortly, they bleed off speed rapidly. And if that’s not enough, you can get some reduced low recoil ammunition and blast away at the range to your heart’s content. Sure, reducing the recoil of the .243 comes at a price in downrange energy, but the goal is a really light recoiling rifle that allows new shooters to develop trigger control, good shooting follow through habits, and enjoy entry into big game hunting. And all that with just a little more recoil energy and velocity than a .243, 100 grain round. With those rounds excluded from the average, the .243 Win has an average momentum of 40lbs/ft.s at the muzzle, 36.7lbs/ft.s at 100 yards, and 25.6lbs/ft.s at 500 yards. Which would lead you to believe that this round might “buck” you even less vs the recoil of that .243, 100 grain round above. If we take a second to look at the averages for these two cartridges, we see a really interesting result. This will obviously be a huge factor in the type of hunting these rounds are suitable for, and we will get back to shortly. Your email address will not be published. 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. If youâre getting out past that range, the .270 Win actually had a flatter trajectory. The trajectory table here tells the tale. This trend continues out to the 500-yard mark where all of the .243 rounds have well below 1,000ft.lb of force associated with them while the .270 rounds vary between 1,000 to nearly 1,500ft.lb of force. Besides ballistic properties, recoil is also another consideration for range shooting. At 500 yards, most of the rounds cluster around the 40-45″ mark except for the Hornady Superformance 130gr bullet. Though, when thinking at a broader level, both of these cartridges have far less recoil than other common hunting and long-range competition shooting cartridges available. Best Concealed Carry Insurance [2021 Update]. A lot of shooters might have never heard of the term while others give it a lot of credence when selecting a round. The 165 grain bullet, .308 recoil vs our 100 grain, .243 recoil above is quite a different story. When they are excluded, we see an average KE of 1945ft.lbs at the muzzle, 1095ft.lbs at 300 yards, and 727ft.lbs at 500 yards. We want to note that what we will be looking at is the actual recoil energy (ft.lbs) generated by firing these cartridges. rifle in .270 generates 16.5 ft-lbs of recoil with a 130-grain load at 3,140 fps. I've been a hunting junkie for my entire life. With the rounds, we have selected for this .243 vs .270 debate, we are confident that anyone with some experience can put these rounds on target within 300 yards. In order to have a meaningful discussion about recoil, we need to first understand, generally speaking, what it is. The .270 Win was developed from the .30-03 casing which many popular cartridges have been derived from. .257 Roberts. When they are excluded, we see the gap close to where these two cartridges are nearly identical. For this reason, we are going to spend a little time discussing it in the context of the 6.5 Creedmoor vs .243. 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. Itâs just something to keep in mind as we examine the potential penetration of these rounds. While these lightweight .243 rounds are much flatter, they also had low BCs and are going to be more susceptible to wind deflection. Do you want a clean pass through, which usually provides better blood trails and conserves meat or do you want full expansion with major damage? 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. Thatâs really saying something too because the 6.5 Creedmoor is known for pretty mild recoil itself. Steve has been a hunting junkie his entire life. With more rounds, we still see that the .270 Win is carrying a great deal more energy than the .243 Win rounds. The trajectory is another ballistic category that gets a lot of attention, especially when comparing two types of cartridges such as the .243 vs .270. And that’s the reason that most states have a minimum legal caliber at just right around the .24(3) mark and do not allow big game hunting with a .223. Overall, the BCs of the .243 are not that bad. Still, we can look at some of the other ballistic characteristics we have discussed so far and draw some conclusions regarding accuracy. At 300 yards, the average fps falls to 2,307fps, right at the same velocity of the .270 Win rounds. When we look at the supersonic limit, we see that the .270 Win has a higher range average than the .243 Win rounds by a little less than 150 yards. From muzzle to 300 yards it is also still carrying over 1,000ft.lbs of force, and the Nosler Ballistic Tip provides more than enough penetration to reach vital organs and expands enough to cause major tissue damage. From the .243 and the .270, there are rounds that can provide the distance that you need. As an Amazon Associate, I earn from qualifying purchases. One of the best marksmen of our generation utilizes the .243 Win. All of this discussion is based strictly off the numbers we have looked at. is the obvious winner. Tat-tat-tat! At the end of each section, we will present averages of the larger data sets for each cartridge. Our problem with this, and with any quantifiable measurements of accuracy is that they tend to depend heavily on the firearm, the person handling the weapon, and environmental factors. So, let’s get the numbers and figure out why. While this is a few hundredths higher than what we see above, itâs still a distinct difference from the .270 Win rounds. If we look back at the cartridge specs from earlier in the article, most could have guessed that this would be the case without needing a graph. There are plenty of values that can be calculated which integrate momentum with other factors, but none that look at momentum alone. With that being said, there are some caveats to how easy it would be. With their speed and shape, these rounds are not going to only penetrate half an inch or bounce off the target. There is a range of bullet weight options for the .243 Win. 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. It is probably more apparent with younger or more inexperienced marksmen. With a solid base plate or hard recoil pad the 270 can kick the salt out of a biscuit and never break the crust if you don't have it right in your shoulder. The change is not too drastic at the earlier yard markers because the velocity of these rounds are so high and velocity is actually squared in the equation for KE. Like the energy associated with the bullets flight, penetration is another important factor for a round’s overall stopping power. Letâs take a look at the sectional density numbers generated from our expanded round list. Though a general statement, you will often hear that 20ft.lb of recoil generated is high enough to have the chance to impact your shot for even experienced marksman, especially if you are not familiar with the firearm and cartridge. There you have it, low .243 recoil is the reason that this little cartridge has remained popular as a youth and new shooter’s staple caliber. Both of these cartridges are popular in the hunting world for a reason. And we are talking about a broad comparison of cartridge to cartridge. This is not the actual âfelt recoilâ or the kick that you will notice when firing. 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. If we look at the .243 Win average when excluding the lightweight rounds, we see an average bullet drop of 6.7 inches at 300 yards, 20.2 inches at 400 yards, 41.4 inches at 500 yards, 120 inches at 700 yards, and 357 inches at 1000 yards. The famous firearm and outdoor writer, Jack O’Connor, championed and pushed this caliber and its abilities in the field and brought it to the forefront of hunting calibers, where it remains to this day. This isnât a peer reviewed research paper. What does the recoil of a 25-06 compare to? Letâs take a look at the average velocities of these cartridges after bringing in more rounds of each. Regardless, those 130 grain bullets have: So the .270 vs .243 recoil is over double the recoil energy and almost 25% more recoil velocity than our 100 grain .243 round. 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. If you get the chance, get some experience with both and greatly widen your hunting and shooting opportunities. It is interesting that we see the bullet drop increase more significantly for the .243 Win rounds as they move out to further distances. Recognize what you want out of your hunting cartridge and you will find that either of these cartridges can become one of your favorites. Some of the links below are affiliate links, which means we will earn a commission on the products or services you purchase using the links. In the simplest of terms, the ballistic coefficient is derived from an equation using several bullets and cartridge variables. All of these rounds are pretty hot, especially the low weight (55 and 58gr) .243 rounds that have a muzzle velocity of nearly 4,000ft/s. Both of these cartridges have the trajectory and the BCs to be effective within normal hunting shot distances. There are a few points that we want to point out before we really dive into the comparisons. 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. Two of the best whitetail hunters I know carry the .243 Win and have for years. Translated, the .270’s recoil is about like your slightly inebriated buddy punching you in the shoulder a bit harder than he meant to, but not as hard as he could’ve. The .243 Winchester also has a lot of history in the long range shooting world. But that’s not the end of the .243 recoil story. If youâre taking shots at 100 yards or less, this round also has the potential to be used on larger game than deer. We should also briefly discuss the light .243 Win rounds. 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). Itâs a little indirect, but the higher the momentum of the bullet, the more resistance it can overcome and keep driving forward. Barely any difference in this .308 recoil vs the recoil energy of the .243. When looking at the heavier rounds (95+), we see that they are much more clustered from muzzle to 500 yards and are also more similar to the .270 Win rounds. 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.
