History of .220 Swift cartridge:
The 220 Swift was developed by Winchester from the 6mm Lee case, introduced by Winchester in 1935, chambered in the Winchester Model 54 bolt-action rifle, and later in 1936 in the Winchester Model 70 bolt-action rifle.
The 220 Swift was an exceptionally fast cartridge for its time, given the powders available in 1935, and it is still one of the fastest calibers today with speeds over 4,100 feet per second, making it still a great varmint cartridge today.
Remington offered an electric primed rifle and cartridge in 220 swift, along with 25-250 Remington and 243 Winchester calibers in 2000. (Those cartridges will not work in a normal primed rifle.)
The popularity of the 220 Swift waned with the introduction of the Remington 22-250 in 1965; however it is still a great caliber.
