The 308 Winchester was introduced to the public as a sporting cartridge by Winchester in September 1952, Winchester's Model 70 bolt action and Model 88 lever action rifles were chambered for the cartridge featuring a 1 in 10" rifling twist, this same cartridge was accepted by the U.S. military known as the T-65 cartridge in 1954 and began chambering M-14 autoloading rifles for the round in 1957, this cartridge is also known as the 7.62 NATO cartridge.
The 308 Winchester has been chambered in at least a dozen countries as a military round in light weapons and machine guns and it has become almost as popular as the 30/06 Springfield that it replaced and is probably better known as a target round as it has been used by bench rest, NRA high power and metallic silhouette shooters quite successfully in competition events internationally. While much has been written about the 308 Winchester cartridge it truly is a great North American, big game cartridge. My own personal favorite bullet weight is 150 grains as it does offer milder recoil with a lot of down range energy for any animal walking in the woods of North America including, elk and moose.
If you were looking to buy a new rifle just to hunt in North America and you were going to hunt white-tailed deer for the most part the 308 Winchester offers plenty of range and energy for that. If you were going to hunt elk and moose some of the time, well the 308 Winchester offers enough bullet weight and energy for that also.
The 308 Winchester is a very good cartridge for those wanting to make use of a .30" caliber bullet for hunting but not wanting the felt recoil of a magnum rifle or 30/06. The 308 Winchester recoil is quite tolerable when shooting 130-150 grain bullets and there is no real advantage to shooting bullets heavier than 165 grains.
