History of the .22 Winchester Magnum Rim fire Cartridge: The .22 Winchester Magnum rim fire a/k/a .22 WMR or .22 Mag was introduced by Winchester in 1959. Oddly, Winchester took a year to come out with a firearm that used the caliber; now, most all firearm makers chamber it. The ballistics are very impressive for a rim fire with maximum pressure at 24,000 P.S.I. (pounds per inch) velocity from 1,400 to 1910 F.P.S. (feet per second) and muzzle energy upwards to 200 FPI (foot pounds per inch) makes this a great varmint cartridge out to 125 yards.
