Winchester introduced the cartridge to the sporting public as the 308 Winchester. Initially, the 308 was chambered in the bolt action Model 70 rifle. Since then, the cartridge has been chambered by virtually every major arms maker in almost every conceivable action type. Public acceptance was slow, due largely to unflattering comparisons to the 30-06. Despite the initial lukewarm enthusiasm, the 308 has become one of the most useful sporting cartridges. The 308 is an extremely accurate cartridge. In fact, it probably is the most inherently accurate 30 caliber commercial cartridge ever produced. Few, if any, other cartridges have been so successful in such a wide range of shooting disciplines. It has also become quite popular as a hunting cartridge and is adequate for most North American big game species, particularly deer-sized game. Sierra® offers this venerable round with it’s 165-grain GameChangerTM bullet as an excellent choice for an all-around performer in the field. TGK B.C. .517
