The .22 Savage Hi-Power cartridge, also known as 5.6×52mmR, was created by Charles Newton and introduced by Savage Arms in 1912. It was designed to be used in the Savage Model 99 hammerless lever action rifle. It is based upon the .25-35 Winchester cartridge necked down to accept a .227 in/.228 in diameter bullet. Its original loading was a 70 grain soft point bullet with a velocity of about 2790 feet per second.[2]
