Winchester rolled the .243 out as a commercial cartridge in 1955. 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. While maybe not as significant to those who mainly stick to the firing range, stopping power is a critical performance factor for hunters for several reasons. We go back and forth on what's better between a .270 Winchester, a .308 Winchester and a .30-06 Springfield. 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? It’s just something to keep in mind as we examine the potential penetration of these rounds. soweit meine erfahrungen sind, bekommt man schrauben, weche mit loctite 243 eingesetzt worden sind, ohne größere probleme wieder los, was bei loctite 270 nicht ohne weiteres möglich ist. I had real trouble with penetration on anything bigger than a roe. Should i just use the .243 because i am mostly just killing deer / pigs? 223 vs 243 vs 270. The averages are pretty similar to the averages from the smaller sample size. At the end of each section, we will present averages of the larger data sets for each cartridge. This isn’t a peer reviewed research paper. 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. We see that the .243 Win produces a fair amount less recoil than the .270. A 300-yard shot with 10mph crosswinds is going to carry that bullet several inches off its flightpath. While it’s not a complete list, you are going to see higher SDs associated with .270 Win rounds in comparison to .243 Win rounds the vast majority of the time. With that being said, there are some caveats to how easy it would be. At 300 yards, all of the rounds are tightly clustered around the 6-7” range, not bad for factory loads. In this section, we are just going to look at our selected factory loads and use data that is presented from the manufacturer with 24″ test barrels where stated. With their speed and shape, these rounds are not going to only penetrate half an inch or bounce off the target. When it comes to hunting, both of these cartridges are pretty popular. 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. If you’re getting out past that range, the .270 Win actually had a flatter trajectory. And we don’t say better performance because it’s all relative to what you’re hunting. And given that, it’s quite possible that the lightweight .243 Win rounds are skewing this data. What we see with the short range trajectory is that the .243 has several rounds that have extremely flat arcs. The .270 Win certainly isn’t unwieldy and we don’t think its recoil eliminates it from the discussion, but the numbers show there is a clear difference between the two cartridges. And while long range shooters might have more interest in the BC than hunters, the latter shouldn’t disregard this metric. Wobei die 243 in Deutschland nicht auf Schalenwild (ausser Reh) zugelassen ist. If you go and look at individual factory loads, you will find quite a few .270 Win rounds that remain supersonic through 1,300 yards while the top performing .243 Win rounds might make it up to 1,100 yards. And again, you have to consider the individual rounds when actually considering what to chamber, but this number does show that there are higher BC options with the .270 when compared to the .243. In a lot of instances, you can’t go wrong going with either the .243 or .270. Of course, if you’re shooting targets, it doesn’t matter. A lot of shooters get a little overboard with velocity. And like we have stated previously, penetration is just part of the overall equation to picking a formidable round with plenty of stopping power. With these two cartridges, the .243 Win produces several less ft.lb of recoil energy than the .270 Win and was one of the only categories where we didn’t see overlap between any of the rounds. … Have my own thoughts, have done some searching on ballistics and Max shot would be 200 yards. This is the same type of trend that we saw when looking at the velocity of these two cartridges as well. So, if you’re planning on using a factory load for these extreme, top level marksmen distances, the supersonic limit is an important factor. 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. For example, the deer in my neck of the woods are larger than those in Texas (so not everything is bigger in Texas! For one all rounder the 308 is better in Australia, there is a broader range of ammo available, the short action is a little lighter and quicker to operate, and it kicks a little less if you are taking multiple shots culling or in a comp. 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. Fox is weapon class 0, aka birdshot with the shotgun. Felt recoil is going to depend a lot of your shooting technique as well as firearm characteristics such as weight and stock design. We have one more little component to this section and that is to pick a couple rounds from each cartridge that we have looked at in this article that we think fills a specific shooting niche well. Should i just use the .243 because i am mostly just killing deer / pigs? There is a range of bullet weight options for the .243 Win. Loctite Purple (low strength): 221 vs 222. Now, determining if that range is significant and should be a big factor in your decision is up to you. 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. Will eventually pass this gun down to my son when he gets into the woods. We also see that this difference is not just due to some outliers, but there is a distinct difference between all of the .270 and .243 rounds. [2] An example of how SD tells us how two bullets will penetrate is if we have two bullets with the same weight, but different diameters, the smaller diameter localizes the force to a smaller area and gives you deeper penetration. You do see better penetration potential for the .270 Win based on its sectional density and momentum numbers. Dicke Pille 2 03.03.2008, 22:08 Uhr @ Jungjager: 270, 243 winchester und 300 winchester magnum. This cartridge was also one of the first few cartridges available to the public that could break the 3,000fps mark. Recognize what you want out of your hunting cartridge and you will find that either of these cartridges can become one of your favorites. Most of the rounds group pretty tightly together with only around 1-2” difference at the 200 mark and 2-3” at the 30 mark, excluding the 55 and 58gr .243 rounds. Die .270 Winchester folgt einem dem deutschen Kaliber 7 × 64 mm ähnlichen Konzept, wobei letztere meist mit schwereren Geschossen geladen wird. I find the .22 is great money/xp from boar, easy one shot to the spine/lung. It has a great BC, and its trajectory is more than flat enough out to 200 yards without having to make major adjustments to shot placement. I don't know but I hate the .243. What this cartridge offered was a long range hunting round that was able to take lighter bullets that were more suitable for target shooting and varmint hunting. 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. Loctite Red (high strength): 272 vs 271 vs 262. It’s a win, win, win solution. 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. Out past 300 yards, you will have to rely on your optics to make some adjustments, but that goes for just about any cartridge. It's really annoying. Like we have said a couple times, there is a lot to interpret when choosing between two cartridges or two rounds of the same cartridge type and unless you have one particular component you are looking for, basing a decision on one performance spec can be a big mistake. While there are higher priced rounds for each cartridge, the .270 is a few dollars more expensive for a box than .243 ammunition. On average, the .270 looks to have a higher sectional density than the .243 rounds, though their average is dropped significantly due to the lightweight 55 and 58gr rounds. The .243 Win is a versatile cartridge that has round options for varmint hunting to medium sized game. The patterns we see from this graph are interesting. We want to note that what we will be looking at is the actual recoil energy (ft.lbs) generated by firing these cartridges. The higher the ballistic coefficient, the better the bullet can resist wind drag and wind drift. 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. When extended out to 400 yards, the gap grows to a little over two inches. We are looking at the force (ft.lbs) from the muzzle to 500 yards downrange. While we would love to cover other bullet designs, casings, and powders, we just don’t have the room to do so. Every shot on the front of the deer is just a flesh wound - even with the polymer tip bullets. 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. This is a pretty significant difference and it mirrors the distinct differences between these two cartridges that we observed in kinetic energy carried by these cartridges. For these reasons, we felt it was important to take a look at the recoil produced by these two cartridges. 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. » 270, 243 winchester und 300 winchester magnum Damit kannst Du in Europa alles umbringen was kreucht und fleucht. Depending on the wind strength and the distance, there are a lot of scenarios in the field where a higher BC might be beneficial. For long-range trajectory (Graph 7) we are working with the same units of measurement but are looking at the arc from the 50 yards out to 500 yards with the test rifles zeroed in at 200 yards. Before we wrap up this article, we want to gather all of the information we have covered from recoil to bullet momentum, and use it to get some idea of what situations these cartridges can be used for. The reality is that both of them suit certain shooting situations better than the other. They have extremely low recoil, aren’t too expensive, and have a flat trajectory that lets you reach out to 300+ yards. The 270 vs 30-06 debate has gone on for about as long as the .270 Winchester and .30-06 Springfield have existed.
