270 winchester vs 308

If we look at individual rounds, there are several .270 rounds that show two to three inches less bullet drop than some of the .308 rounds. With a degree in Microbiology and several years of doctoral work manipulating bacterial genes, he attempts to merge the rational and unbiased thinking of scientific research with the passions of hunting and fishing. As most of you know, the laws of physics work on a flying bullet and rather than fly in a perfectly straight line, the flight path takes on a parabola shape. Other factors such as velocity and bullet design also play a role in penetration, but we will mostly keep the conversation on sectional density. As you can see, there is a significant difference in the bullet trajectories between the two cartridges. U.S., Canadian, British, and other allied nations used the cartridge at the start. Providing approximately 90% of the power of the .30-06 in a smaller package, the cartridge soon became very popular and is now one of the most widely used big game hunting rounds in North America. This round was originally brought to be in the form of the 7.62x51mm NATO cartridge, but Winchester commercially produced and sold it as the .308 Winchester. At a MV of around 2600 fps, nearly all bullets will perform reasonably well, both ballistically and, more importantly, terminally out to 200 or 250 yards. The US Army began the search for a new rifle and cartridge after receiving a deadly demonstration of the capabilities of the revolutionary new Mauser rifle and 7mm Mauser cartridge in the hands of Spanish troops in Cuba during 1898. Similar to the abundant ammunition choices available in .308 Winchester and .270 Winchester, there are also plenty of quality rifles manufactured in the two cartridges. While we might give the edge to some of the .270 rounds for velocity, especially muzzle velocity, we will see that this similarity doesn’t always translate to other ballistic characteristics and we will look at those stats and discuss the reasoning in the next several sections. Based on their hunting use, we don’t see any real difference in price between the two. As for the penetration potential of these cartridges, the .270 Win rounds had slightly better SDs than the .308 Win rounds but the .308 Win rounds brought a little more momentum, especially at the more common hunting ranges out to 400 yards. The.270 Win HAS less bullet, "Drop" (Flatter Trajectory) than the.308 and with, a 140 grain Nosler AccuBond or, partition, starting at 3,000 FPS, should be an efficient "Elk slayer" to about, 500 yards ! While the .270 had a very high muzzle velocity compared to other popular cartridges of the day, it was not an instant commercial success. While 2900 fps sounds cool and all, a high impact velocity means the bullet will almost certainly fragment on impact when using lower-end bullets. While a gun and the ammunition may be capable of sub-MOA accuracy, real-life hunting is not like shooting on a shooting stand. 270 vs 30-06: Ammunition Selection. My shots rarely exceeded 125 yards or so in the foothill country that I hunted in central Wyoming. This scenario is also omitting bullet design, which in real world scenarios, is just as important as any of the data we are looking at. And if you go back and look at the differences in bullet drop at long ranges you will see that there are .308 rounds that are more than capable of 400 and 500-yard shots. However, the 7.62x51mm achieved that performance with a much shorter case (51mm vs 63mm) due to advances in powder technology that occurred after the development of the .30-06. 150 grain, 165 grain, 168 grain, and 180 grain bullets are most popular for that cartridge. Instead of .284″ bullets like the 7mm Mauser (and more recently developed cartridges like the 7mm-08, .280 Remington, .280 Ackley Improved, and 7mm Remington Magnum), the .270 Winchester used .277″ bullets which undoubtedly hampered adoption of the cartridge to a certain degree. Pas de choix de grain (130-140-150Gr), Vitesse ultra trop vite pour la chasse de proche, certain s'en servent pour toutes les chasses, même le Coyote et la Marmotte. Though there is quite a bit of overlap in barrel lengths, .270 rifles often have slightly longer barrels than .308 rifles. The .270 is fitted with a .277″ diameter bullet. Hitting small game with a heavy grain .308 is not going to leave anything behind and is just overkill and a waste of money. Pour les bêtes que l'ont chasse au Québec. At the 300 yard mark, the difference between the average bullet drop of these two cartridges is nearly identical. The .308, as the name implies, has a 30 cal bullet with a .308″ diameter bullet. Buy some of the best .270 Winchester hunting ammo here. Though its military career was short-lived, the .308 has become an extremely popular round in civilian use from its conception to modern day. The data used to compare the trajectory and wind drift of the cartridges was obtained from Federal. I would suggest reconsidering the need for long-range hunting (above 400 m / 450 yards). Longer track record. 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. If we step back and look at the two cartridges, we see some pretty interesting results. There is something to be said about computer-generated data when it comes to comparing two cartridges. If I was just game hunting though I would get the 270 for … Let’s take a look at the ten rounds we have selected for this article and see if the trend continues (Graph 2). I have two, one in a 270 and one in a 308. Note: while the case capacity figures listed below do give a good indication of the differences between the three cartridges, exact case capacities vary slightly according to the brand of brass used. Thread starter ATX762; Start date Jul 21, 2017; 1; 2; Next. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges.Interestingly enough, all four loads have almost identical recoil. From this cartridge, the 7.62×51 NATO round was also designed and saw brief use in the US military in Vietnam with the M14 Garand. 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.

You can find a case of .308 for twenty bucks and a box down the aisle might be forty dollars. The long range trajectory for this round is not as flat as other .270 rounds but it is still manageable at 400 yards and to be honest, any range after that we are not concerned with when it comes to hunting. That not only pertains to the ballistic categories but other performance categories as well. I think the majority of hunters and shooters would agree that the .270 Winchester and .308 Winchester are outstanding hunting cartridges. And receive our newsletter with the best articles covering guides, guns & gear. Additionally, the Browning X-Bolt, Kimber Hunter, Mossberg Patriot, Nosler Liberty, Ruger American, Ruger Hawkeye, Savage Axis, Thompson Center Compass, Tikka T3, and Weatherby Vanguard are available in both calibers. .308 Winchester vs. 7.62×51mm NATO. These diameters play a role in the weight of the bullets that are used by the two cartridges and in other performance specs that we will look at later in the article. So, let’s take a look at the ballistic coefficients of the ten rounds we are comparing (Graph 4). Interestingly, when looking at more rounds, we see that the .270 Win takes a pretty big leap over the .308 Win. Like many other cartridges developed in the United States, the story of the .270 and .308 Winchester begins with the .30-06 Springfield. While less than an inch difference at 200 yards, nearly four inches at 300 yards, and a little more than five inches at 400 yards, might not seem like much, it can easily be the difference between success and failure. Of course, with different types of rounds for these two cartridges, there will be certain rounds that might be more significantly different. There are some trends between cartridge types though. If you begin picking out individual rounds, you can find some huge differences between .270 and .308 rounds where the .308 round shows between fifteen and twenty more inches of bullet drop. All were Remington Core-Lokt, an extremely popular bullet in the deer woods. We hope to bring all this together more clearly in the application discussion later in the article. Just take a look at the ten rounds that we have looked at in this article. 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. Measurements were taken out to the 300-yard mark (Graph 6). If we take the average of the given rounds, we see that the .270 has a slight advantage with only a hundredth of a difference. 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. Both cartridges are also well suited for handloaders and reloading components for both cartridges are widely available. While it’s always a hard choice, the .270 vs .308 might be one of the toughest decisions you will face. We also have selected some pretty high performing .308 rounds. The release of the .270 Winchester in 1925 in the Winchester Model 54 rifle saw the beginning of the American love affair with velocity, as well as the laying of a solid foundation for the American bolt-action sporting rifle.At the time, the lever gun held court in the hunting fields, though through the writings of Mr. O’Connor, change was on the wind.
