308 brass and the .308 Winchester (pronounced: “three-oh-eight”) is a rimless, bottlenecked rifle cartridge and is the commercial cartridge from which the 7.62×51mm NATO round was derived. The .308 Winchester was introduced in 1952, two years prior to the NATO adoption of the 7.62×51mm NATO T65. Winchester branded the cartridge and introduced it to the commercial hunting market as the .308 Winchester. Winchester’s Model 70 and Model 88 rifles were subsequently chambered for the new cartridge. Since then, the .308 Winchester has become the most popular short-action, big-game hunting cartridge worldwide It is also commonly used for civilian hunting, target shooting, metallic silhouette, bench rest target shooting, metal matches, military sniping, and police sharpshooting. The relatively short case makes the .308 Winchester especially well-adapted for short-action rifles. When loaded with a bullet that expands, tumbles, or fragments in tissue, this cartridge is capable of high terminal performance.

The . 308 Winchester certainly has enough energy to kill deer, pronghorn, elk, moose and bear out to 300 yards, but the bullet drops fast and it’s trajectory looks like a bell shaped curve by 500 yards.
Although frequently used in 1,000-yard engagements, the .308 Winchester is often regarded as a “900-yard cartridge.” It gets this reputation because most bullets fired from .308 Win. rifles fall below the speed of sound slightly before they reach 1,000 yards. In Bryan Litz’s book Applied Ballistics For Long-Range Shooting, he touches upon this aspect and covers certain designs that begin to tumble end over end as they broach this mark. Such destabilization happens as the bullet becomes subsonic. During this transonic period, most projectiles experience turbulence and get knocked off course, making them far less consistent than they were just a few hundred yards prior. But, with millions of rifles around the world chambered in this classic cartridge, we couldn’t just abandon the .308 Win. as a long-range option—particularly not with long-range shooting currently as popular as it ever has been. Fortunately, Berger’s 185-grain Juggernaut Target bullet (bergerbullets.com) was designed for exactly this purpose.
