Brief History On 220 swift ammo for sale:

Grosvenor Wotkyns, in an effort to achieve extremely high velocity, necked down the.250-3000 Savage to create the prototype for the.220 Swift between 1934 and 1935. The commercial variant manufactured by Winchester was based on a necked-down 6mm Lee Navy cartridge, but it has a bigger, more difficult-to-load protruding rim to accommodate 12mm-wide cartridges.

This headspace was already deemed antiquated by the 1930s. thread size.306″ Winchester’s Model 54 bolt-action rifle received a new caliber in 1935: the.220 Swift. Standard issue for the Winchester Model 70 bolt action from its inception in 1936 until its demise in 1964 was the.220 Swift.
