.22 Savage Hi-Power - Wikipedia
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.
As time went on, other .22 centerfire cartridges outstripped it in performance such as the .220 Swift, and with the advent of the .223 Remington in the 1960s, the cartridge was considered obsolete.
Although the .22 Savage Hi-Power is no longer made in the United States, it is still produced by several European makers. In Europe, the .22 Savage Hi-Power is called the "5.6×52mmR", and is still made by RWS, Norma, Sellier & Bellot, and Prvi Partizan.
