Swift

The .220 Swift may be the best varmint cartridge ever produced. This ballistic phenomenon was developed by Winchester and introduced in 1935 in the new Model 70 bolt action rifle. Discontinued by Winchester in 1964, it is currently available in rifles made by Remington, Ruger and Savage. If anything, the .220 Swift is more popular now than ever.

With a muzzle velocity of 4,110 FPS, the .220 Swift is still the fastest commercial cartridge in the world. Unlike many cartridges, the Swift will produce excellent accuracy at maximum velocities.

Accurate 2700 is the best choice for duplicating factory ballistics with 50-grain bullets. Accurate 4350 also performed quite well, especially with heavier bullets.

The SAAMI Maximum Average Pressure for the .220 Swift is 54,000 C.U.P. Our data was developed in P.S.I., it does not exceed that pressure level.
