The.22-250 Remington is a very high-velocity, short action, .22 caliber rifle cartridge primarily used for varmint hunting and small game hunting. It does find occasional use by women and young children for deer hunting because of its low recoil. Some jurisdictions prohibit the use of cartridges smaller than 6mm for deer hunting. This cartridge is also sometimes known as the.22 Varminter or the.22 Wotkyns Original Swift. Along with the.220 Swift, the.22-250 was one of the high-velocity.22 caliber cartridges that developed a reputation for remote wounding effects known as hydrostatic shock in the late 1930s and early 1940s.
