History
Originated as a wildcat cartridge around 1937, developed independently by several gunsmiths including J.E. Gebby. Known as .22 Varminter for decades. Remington commercialized it in 1965 as the .22-250 Remington. It immediately became the dominant varmint cartridge, achieving velocities near .220 Swift from a shorter case that fits standard-length actions. Extremely popular with prairie dog hunters and long-range varmint shooters.
