What is a 220 Swift? What is a 220 Swift used for? Historical Notes: The .220 Swift was developed by Winchester and introduced in 1935 as a new caliber for the Model 54 bolt-action rifle. When the Model 70 Winchester bolt-action was first issued, in 1936, the .220 Swift was one of the standard calibers offered and continued to be until it was discontinued, in 1964. Now, the Savage Model 112V, the Ruger Model 77, and the Ruger No. 1V single-shot are offered in the .220 Swift chambering. The Model 70 Winchester is no longer made in this caliber. Norma of Sweden lists the .220 Swift with a 50- grain bullet at 4110 fps, and it also sells unprimed brass cases for reloading. Hornady/Frontier offer 55-grain SP and 60-grain HP loadings.

The prototype for the .220 Swift was developed in 1934-'35 by Grosvenor Wotkyns, who necked down the .250-3000 Savage as a means of achieving very high velocities. However, the final commercial version developed by Winchester is based on the old 6mm Lee Navy cartridge necked down. It is a semi-rimmed case. What is a 220 Swift? What is a 220 Swift used for? General Comments: The .220 Swift was and still is the fastest commercial cartridge in the world. It is also one of the most accurate super-velocity .22 cartridges ever developed. Its popularity has been somewhat retarded by the fact that ammunition in this caliber is expensive. Swift barrels have never been noted for long life, but this factor has been negated to a large degree by development of modern, erosion-resistant barrel steels since World War II. Factory ammunition has always featured the 48-grain and 50-grain bullets, but the Swift will handle the 55-grain or heavier bullets quite well at slightly reduced maximum velocity. The .220 Swift is considered adequate on all animals up to deer size. There is certainly plenty of field evidence to demonstrate that, on occasion, it will give fantastic one-shot kills on deer and antelope. However, the .220 Swift tends to be erratic in its performance on large animals, and most states will not permit its use on big game of any kind. Properly constructed bullets would almost certainly solve this problem on animals to mule deer size. In any case, factory bullets are designed for quick expansion on light animals. Most varmint hunters agree that the .220 Swift is the best varmint cartridge made. It remains sufficiently popular that various manufacturers occasionally chamber it. What is a 220 Swift? What is a 220 Swift used for? In a 2000 press release, Remington announced the availability of electronic ignition 220 Swift ammunition for use in its new (and now defunct) EtronX rifle. The initial loading uses a 50-grain Hornady VMax, polymer-tipped bullet. Owing to the unique primer, this ammunition will not work in a conventional rifle (just as conventional ammunition will not work in the EtronX rifle). Except for the primer, this ammunition uses conventional components. What is a 220 Swift? What is a 220 Swift used for?
