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.
Designed around the hard-hitting performance of the famous Hornady V-Max bullet, this ammunition is specifically designed for supremely accurate long-range shooting. The polymer tip enhances accuracy and promotes devastating expansion. It also increases the ballistic coefficient and stabilizes the bullet in flight. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
