The .220 Swift (5.56×56mmSR) is a semi-rimmed rifle cartridge developed by Winchester and introduced in 1935 for small game and varmint hunting. It was the first factory-loaded rifle cartridge with a muzzle velocity of over 1,200 m/s (4,000 ft/s).
This lever-action rifle was not well received by varmint hunters, but the cartridge and wildcat modifications (like the .219 Donaldson Wasp) became popular in other actions.

Two years later, in 1965, Remington Arms adopted the .22-250, added "Remington" to the name and chambered their Model 700 and 40 XB match rifles for the cartridge along with a line of commercial ammunition, thus establishing its commercial specification. [6] The .22-250 was the first non-Weatherby caliber offered in the unique Weatherby Mark V ...

In 1969, Remington introduced several upgrades for the rifle, including a longer rear bolt shroud, a jeweled bolt and improved stock finishing. Four years later, the production of left-handed versions of the rifle began, to compete with the Savage Model 110 , which was at that time the only major rifle manufactured with a left-handed variant.
Most straight-pull rifles have a striker firing mechanism (without a hammer), [citation needed] and models using a hammer usually have a comparably longer lock time than hammer-less mechanisms. The Anschütz Fortner action used in biathlon is a good example of an ergonomical straight-pull rifle with good economy of motion and high operating speed.
