History of 5.6x52mm Rimmed Ammo
The 5.6x52mmR is also known as the .22 Savage High Power and the .22 Imp. It was developed by Charles Newton in 1912. Savage Arms produced the cartridge and chambered their popular Model 99 lever-action rifle for it. Newton's cartridge was accurate and based on the .25-35 Winchester case but capped with a 0.227 caliber bullet.
