Prices and availability vary from region to region, but ammunition for both cartridges is widely available. A lot of marksmen want to know this metric because when a bullet falls below supersonic speeds, their flight becomes more unstable and the difficulty of being accurate increases substantially. Hitting small game with a heavy grain .308 is not going to leave anything behind and is just overkill and a waste of money. I have two, one in a 270 and one in a 308. Momentum is a function of the bullet’s mass and its velocity and since we have looked at both, you should already have an idea of how these two cartridges will look in comparison to each other. Just take a look at the ten rounds that we have looked at in this article. The cartridge is the same length as the .280 Remington, both of which are longer than the .30-06 Springfield.The .270, .280, and .30-06 were all derived from the .30-03 parent case. The .308, as the name implies, has a 30 cal bullet with a .308″ diameter bullet. We see the .308 Win rounds carrying on average more momentum than the .270 but as they move downrange, we see the the .270 Win rounds gaining ground. Velocity is also important to hunters because it also influences terminal ballistics and how well the bullet will expand and transfer kinetic energy to the target. It is more clear at this range where the rounds for each cartridge begin to group. If you’d like to learn more about the evolution of intermediate cartridges, read the article below. You will find the bullet weights of .308 cartridges to fall between 125 and 170 grain with a few outliers in both directions. Jul 21, 2017 #1 A. ATX762 Senior Member. While there are a few technical differences between the two, most refer to them simply as “the 308.” If you’re familiar with historic battle rifles like the M14, H&K G3, FN FAL or the M60 machine gun, then you’r… You can see that the .270 is a much longer and skinnier cartridge than the .308. So, these numbers could fluctuate a little based on changing those variables, and we do not have the powder charge that is used by the manufacture of the round. And even though the .270 is skinnier, its .5 inch increase in the casing length allows it to hold more powder and can withstand 3,000 more units of pressure than the .308. 5.56x45mm NATO, basically the military version of .223, launched in 1961. Both cartridges will work, but the .308 Winchester is probably the better choice in this case since it uses larger diameter and heavier bullets that are well suited for very large or tough animals. While there are some rounds from each cartridge that are pretty similar in velocity, the trend of the .270 rounds having an average of 200-300ft.sec more velocity than the .308 rounds extends out to the 500-yard mark. This is another excellent option for medium to larger game. my choice is the 270 win, shooting range for animals is most in the 200 yards. By the same token, the .270 has taken untold numbers of moose, elk and plains game without any issues. The fact that the .270 and .308 each have very devoted fan clubs can also make it difficult to navigate the debate. 1 of 2 Go to page. In the end, the best cartridge all depends on the type of situation they will be used. Get a nice hunting rifle chambered in the cartridge that you think fits your needs the best, learn to shoot it well, use quality bullets, and you’ll be well prepared for most common hunting situations. However, the flat trajectory and resistance to wind drift of the .270 Winchester makes it a really good choice for game that might require a longer shot such as pronghorn or mule deer. Anything within that yard mark is no issue. When looking at the .270 vs .308, it’s difficult to draw a firm conclusion on which is the better cartridge. Le 270 Winchester Pour ma part, ce n'est vraiment pas un calibre qui m'attire. C'est même un des pire. On the other hand, since it shoots heavier and larger diameter bullets, the .308 Winchester has a clear advantage when hunting larger species moose, elk, and caribou. Both are fantastic cartridges that have been tried and tested in the field for decades. I moved away from Wyoming and settled here along the Gulf Coast of Florida where deer are much smaller. For the most part, we see a lot of the same results with the larger data set. But if I were to go out west and shoot long range it would be a toss up between the 308 and the 300 win mag. Where calculations are made, we will be sure to make clear our variables. Momentum (not KE) is king when it comes to penetration, and heavier bullets retain it better than lighter bullets. Note: there is quite a bit of overlap with the performance of various 150 grain loads for both the .270 Winchester and .308 Winchester. Of course, these are just averages and there are definitely .308 rounds that perform above the average. I compared a 150-grain in the 308 Winchester against the 140-grain Core-Lokts in the 7mm-08 and 260 for two reasons. The originalÂ 7.62x51mm NATO M80 ball load fired a 146 grain full metal jacket (FMJ) bullet at 2,750 feet per second (2,469 foot pounds of muzzle energy). As the rounds move downrange, we do see the .308 Win rounds start to lose momentum at a faster rate than the .270 Win rounds. Another important concept to take away from this graph is that all of these rounds remain supersonic all the way out to 500 yards and if we were to extend this range we would see this trend continue for several hundred more yards. The .270 Winchester is a very flat shooting and moderately powerful cartridge, especially considering that it’s nearly 100 years old. The extent of this difference may or may not be enough for you to decide one way or the other. We also have selected some pretty high performing .308 rounds. The BC of this round might not be as high as long-range shooters would like to see, but the flat trajectory might compensate for this with a bullet drop of only 33 inches at 500 yards. At this distance, the average drop of the .270 rounds is 11.6 inches while the average drop of the .308 rounds is 14.68 inches. They are both incredibly effective (and popular) deer hunting cartridgesÂ and hunters armed with the .270 and .308 make up a significant portion of the annual whitetail deer harvest each year in the United States. Case capacities for the .270 Win and .308 Win were obtained fromÂ Nosler. As you can see in the photo below, the .270 Winchester and .308 Winchester cartridges have very different external dimensions. To put this into perspective, a Boeing 737 commercial airliner travels at a cruising speed of 600 mph, or 880 fps. Though the differences are slight overall, we can pick out certain rounds where there is a 4 or 5ft.lb increase in recoil energy from a .270 to .308 round. For more experienced hunters, most hunting cartridges, including the .270 and .308, the recoil is going to be manageable. While we think it has a large role in making difficult shots easier, don’t make the error of thinking that if a bullet has a high BC, that it is going to do all the work for you or replace experience and skill. Le calibre 270 winchester, apparu en 1925, est un calibre qui offre beaucoup de polyvalence avec sa trajectoire tendue et sa puissance d'un bon niveau.

Just from looking at these ten different rounds, it’s pretty obvious that there is not a whole lot of difference between the two different cartridges. The .270 can be thought of as a necked down version of the .30-06. Buy some great .308 Winchester hunting ammo here. While recoil is more or less comparable between the two cartridges, typical .308 Winchester loads do not have as flat of a trajectory as typical .270 loads. Obviously, just from this little bit of information, we can already guess that the two cartridges are going to show some differences in their ballistics and other We will see how these specifications influence the ballistic and other properties of the cartridges shortly. However, the .308Â performs better with heavier bullets than the .270 and is available in a widerÂ range of bullet weights and models. It’s a good example of how bullet design is the driving factor in this category. Each gun has its own unique qualities that are going to influence the numbers. Thanks Brian. To be a great hunter, you might need to turn to more than one cartridge on your adventures. There are definitely more .308 Win rounds above that mark and there are definitely more .270 Win rounds below that mark, as the averages imply. John .270 Winchester.

Heavier, more stoutly-constructed bullets are almost universally better at penetration, given their lower velocities. Based on their hunting use, we don’t see any real difference in price between the two. These projectiles quite often take advantage of the latest developments in bullet development and offer advantages in precision and ballistic coefficient compared to the bullets used by the .270. Let’s move on and look at a second metric for this category. You can see that the flattest shooting rounds belong to the .270 while the rounds showing the steepest drop are .308 cartridges. Home defense or hunting, small or big game, short or long distance are only a few options that you have to think about. Best Concealed Carry Insurance [Comparison Chart].

The .270 came from the .30-03 which saw very brief use in the United States in the early 1900’s. C'est même un des pire. However, the 7.62x51mm achieved that performance with a much shorter caseÂ (51mm vs 63mm) due to advances in powder technology that occurred after the development of the .30-06. The data used to compare the trajectory and wind drift of the cartridges was obtained from Federal. For convenience, we have also included the average tables for the various performance categories below. Using smokeless powder and a 150gr pointed bullet fired at a 2,700fps, the .30-06 Springfield was a gigantic improvement over other popular American cartridges used during that era like the .30-30 Winchester and theÂ .45-70 Government.

In fact, .270 has a sharper kick than the .308. As you can see in the photo below, the .270 Winchester and .308 Winchester cartridges have very different external dimensions. 223/5.56 vs 7.62×39: Everything You Need To Know. This difference in trajectory widens slightly as the bullets move out to the 300-yard mark. This is also an example of how bringing in more rounds might give us a clearer picture. The .308 Winchester and .270 Winchester are two of the most popular centerfire rifle cartridges in North America. It is going to give us an idea of the potential each round had has for penetration. Néanmoins, cette munition est peu adaptée aux gibiers de très grande taille. With moderate recoil that’s roughly comparable to the .308 and noticeably lighter than the .30-06 Springfield, most shooters and hunters can handle it without much trouble. By looking at this information, we hope to better tease apart which cartridge is better suited for specific hunting situations. For any round of any cartridge type, you want to see a flat trajectory with minimal bullet drop. What should be taken away here is that both of these cartridges have rounds that are going to range in sectional density. For this reason, the .270 Winchester is used in standard/long action rifles, while the .308 Winchester is the poster child for … By necking down the .30-06 case to shoot smaller diameter bullets, the designers of the .270 Winchester built a cartridge with a higher velocity, flatter trajectory, and less recoil than the .30-06 Springfield. Still, for the sake of being thorough, we wanted to see how the two compare in this category. Their omission here does not reflect our attitude towards those rounds. With the larger data set, we still see the same trend of the .270 Win rounds bringing higher velocities than the .308 Win rounds. For the muzzle velocity, we used the data provided by the manufacturer so take that with a grain of salt as well. The .270 Winchester might be the better choice for you. Bullet momentum is another factor that goes into stopping power and is always involved in the arguments for the best indicator for stopping power. If you’re dead set on choosing a cartridge or specific round to get a little recoil as possible, there are more options for lighter rounds with the .270 Win but the majority of the factory loads for both cartridges are in the 20ft.lb plus or minus 2 range.

When used in the right scenario, both the .270 and .308 are effective cartridges for bringing home game or smoking the competition on the range. Overall, the heavier bullet weights of the .308 rounds are what give the .308 cartridge a slightly higher average when it comes to the sectional density. The original .270 Winchester load shot a 130 grain bullet at a velocity of 3,140 feet per second (2,846 ft-lbs of energy). For our top .308 Win range round we like the 168gr Hornady BTHP Match. Regarding recoil, we have seen that both cartridges generate a similar amount of energy, so we don’t think that distinguishes either of the two cartridges regarding accuracy.
