You do see better penetration potential for the .270 Win based on its sectional density and momentum numbers. Longer track record. The military developed it as a small-caliber, high-velocity round for NATO forces. We see that the .243 Win produces a fair amount less recoil than the .270. Like the energy associated with the bullets flight, penetration is another important factor for a round’s overall stopping power. Please click the above links to take a look at all of the .243 Winchester and .270 Winchester ammo we have in stock and ready to ship, and let us know any parting thoughts in the comment section below. Before we jump into the various categories for which we will be comparing these two rounds, it’s important to note that slight changes to certain variables can impact their performance. And for medium game, where the .270 Win could be used, the .243 is perfectly fine. For that reason, the 25-06 vs 6.5 Cree… Below we have listed five popular hunting and target rounds for each cartridge. The first is that we understand we are only scratching the surface of the amount of round options that are available for these two cartridges. Of course, we are only looking at factory loads, but it still gives you an indication of this cartridges capabilities. are great cartridges, but which one is better? Our website lists special deals on 9mm Ammo, 10mm Ammo, 45-70 Ammo, 6.5 Creedmoor ammo, 300 Blackout Ammo, 10mm Ammo, 5.56 Ammo, Underwood Ammo, Buffalo Bore Ammo and more special deals on bulk ammo. I use .270 and it has not failed me. 0 0. The averages are pretty similar to the averages from the smaller sample size. There is a lot of overlap between the performance of these cartridges and also categories where there are clear differences. This isn’t a peer reviewed research paper. And like we have stated previously, penetration is just part of the overall equation to picking a formidable round with plenty of stopping power. The following ammunition cartridge ballistics information and chart can be used to approximately compare .243 Winchester vs .270 Winchester ammo rounds. 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. Overall, the BCs of the .243 are not that bad. 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. Secondly, most hunters want enough stopping power to be able to make a clean and humane kill of the animal with causing unneeded suffering. 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. Still, force generated still translates to felt recoil to some extent, especially when keeping the variables consistent as we have done here. An Overview Of 6.5 Creedmoor Vs. 270 270 Winchester. There's a lot of debate as to what the best deer rifle is, but the .243 definitely has it going on. 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. For factory loads, there are options for both that have supersonic flight out to the extreme ranges possible for most marksmen, but neither probably have the other performance specs that are also needed at for accuracy at 1,000 yards. Oct 28, 2015 #16 For deer at 100-200 yds, you will never know the difference and neither will the target. Of course, if you’re shooting targets, it doesn’t matter. There is a balance to penetration. With the lighter rounds included, the .243 Win has anywhere from 100 to a little over 200 more fps throughout the first 300 yards of the bullet’s flight, though, like the smaller sample size, we do see the .243 bleed off velocity at a higher rate and we see the .270 Win actually outperform the .243 in terms of velocity at the 400 and 500 yard range. Loctite 242 vs 243 – Loctite Threadlocker Comparisons September 2, 2020 April 7, 2019 by greaseexpert Loctite 242 and 243 are two of the most popular Loctite products and that’s saying something – they have hundreds of different products to choose from. 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. These, with the higher KE make it a more suitable cartridge for larger game at these ranges. For the quantitative factors that we will look at, there are arguments all over the place as to which is the best indicator. 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. The patterns we see from this graph are interesting. For medium game within 300 yards, both of these cartridges carry enough kinetic energy to cause damage. I do not feel comfortable using it. You’re looking for a minimum of 900 foot-pounds of energy at impact on a deer so the hunting bullet works right. The averages do give the slight edge in velocity to the .270 Win when not including the sub 60 grain .243 Win rounds. A 300-yard shot with 10mph crosswinds is going to carry that bullet several inches off its flightpath. Pros: Better performance at medium ranges. Re: 243 vs 270 by KurtR » Sat Jun 19, 2010 5:34 pm Any time you want to come out and shoot some p-dogs at 500 plus and show us your knowledge of shooting and ballistics the invite is open. For hunting purposes, this might be the more relevant trajectory information as a vast majority of shots taken in the field will be within and up to 300 yards. Even when not considering the lighter rounds, there is not any overlap between the individual rounds of these two cartridges. We also see that all of these rounds remain supersonic through the 500 yard mark with all of the hovering around the 2,000fps mark. If you are getting into the more extreme ranges, you might also think about the differences between factory loads of these two cartridges and their ability to stay supersonic. I compared the stat between them and see that the .243 has more accuracy so thats why I still use it. Perhaps both cartridges can be used for a lot of situations and perhaps in some situations one cartridge might be better suited. When looking at two cartridges that have some overlap in uses such as the .243 vs .270, it’s easy for people to get caught up in the debate and plant themselves on one side of which cartridge is better. To compensate for clear and concise and accurate representation, we actually compiled a lot more rounds for each cartridge. You’re going to get penetration, but does one cartridge have the higher potential penetration? In this article, we are going to look at several of the most popular factory loads for each of these cartridges. 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. Lighter bullets tend to have lower ballistic coefficients as they are more prone to being thrown off by crosswinds and are more susceptible to being caught up in wind drift. Should i just use the .243 because i am mostly just killing deer / pigs? 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. 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. Discussion Starter • #1 • Feb 6, 2014. We gathered all of the BCs for our selected rounds from the manufacturer and have presented them here in graph form (Graph 4). You should enough shots in a row and recoil fatigue can also cause a decrease in your efficiency. So they are bringing down the average roughly 1lb/ft.s from the numbers in the table. When we look at these rounds, it appears to be all over the place right out of the muzzle. And even that last part has been and is still debated. If you’re getting out past that range, the .270 Win actually had a flatter trajectory. U.S., Canadian, British, and other allied nations used the cartridge at the start. A .243 can travel quite far and this rifle proves that it can be done so long as you sight in the scope properly. 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. While there are higher priced rounds for each cartridge, the .270 is a few dollars more expensive for a box than .243 ammunition. The .308 Win. This is by no means a comprehensive list of the available options, but because they are popular and used heavily and we think it covers a lot of the popular grain weights and styles, it will give us an accurate depiction of how these cartridges stack up against each other in the ballistics and other performance compartments. Everyone’s got their go to rounds. When you look at individual rounds and individual users, then there are going to be more distinct differences, especially at ranges out past 300 yards. We offer a 100% Authenticity Guarantee on all products sold on our website. I have every gun you listed to try, .243, 22-250, 7mm-08 and a .270 I need to actually go dial in all but the .243. Still, we can look at some of the other ballistic characteristics we have discussed so far and draw some conclusions regarding accuracy. Fast expanding bullets will cause larger wounds, but might not penetrate down to vital organs of larger game. If we take a second to look at the averages for these two cartridges, we see a really interesting result. Where the differences between these two cartridges, from a hunting perspective, come into play is their stopping power. As you move out to the 400-yard mark, you will begin to see some distance forming between the rounds. Even so, both cartridges are relatively flat shooting, especially for factory loads and when compared to other cartridges on the market, the bullet drop is minimal. 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.
