6mm Remington

The 6mm Remington was introduced by Remington Arms Company in 1955 as the .244 Remington. It is based on necking down the .257 Roberts. Originally intended as a varmint and predator cartridge. Originally Remington offered factory ammunition with 75 grain bullets for varmints and 90 grain for deer. In 1963 Remington renamed the cartridge, calling it the 6mm Remington. Rifles marked 6mm Remington have a 1 in 9-inch (230 mm) twist and can stabilize most commercially available 6 mm bullets.
