The .308 Winchester is simply the most popular short-action big-game-hunting cartridge in the world, capable of taking down just about any size game in North America. 308 is the civilian version of 7.62x51 NATO that is used by militaries worldwide. It has moderate recoil when shooting out of the larger AR-10 platform. 308 projectiles range in weight from 110 to 180 grains, offering better terminal performance and long range capabilities over 5.56 NATO and 223 Remington.
