.22 Remington Jet

The .22 Remington Jet (also known as .22 Jet, .22 Center Fire Magnum, or .22 CFM) is a .22 in (5.6mm) American centerfire revolver and rifle cartridge.

Developed jointly by Remington and Smith & Wesson, it was to be used in the Model 53 revolver, which first appeared late in 1961. It traced its origins to potent wildcats such as the .224 Harvey Kay-Chuk, which ultimately derive from the .22 Hornet.

By 1972, the Model 53 remained the only revolver chambered for it, while Marlin in 1972 was planning a lever rifle in .22 Jet.

The .22 Jet was designed as a flat-shooting hunting round for handguns, and it is suitable for handgun hunting of varmints and medium game out to 100 yd (90 m). The 2460 ft/s (750 m/s) and 535 ft-lbf (725 J) claimed for factory test loads did not prove out in service weapons.
