Winchester

The .308 Winchester was introduced in 1952 as the sporting version of the newly adopted U.S. T-65 or NATO 7.62 x 51mm military round. It was adopted as the official U.S. military rifle cartridge in 1954 along with the M-14 rifle.

The .308 was the result of the military's experiments to retain the power of the .30-06 cartridge in a smaller package. The advent of Winchester ball powder permitted loading the 7.62x51mm to equal the velocities of .30-06 service ammunition.

Since 1954 the .308 Winchester has become the premier .30 caliber target cartridge and has gained a loyal following among hunters.

Because this is also a military cartridge, there is an almost infinite variety of components available for loading the .308. When using military cases, the handloader must exercise caution because many of these are much heavier than commercial brass. Charge weights may require up to 12% reduction to maintain pressures within safe limits.

The SAAMI Maximum Average Pressure for the .308 Winchester is 52,000 C.U.P. and 62,000 P.S.I.
