We have covered a lot of ammo on our blog to help people learn about different calibers and cartridges. When I took a deep dive into learning about 220 Swift, I was surprised that it’s been around since 1935.

I will talk about the history of the round, its purpose, its performance, a few guns that shoot it, ammo availability and where to buy it, and some of the most frequently asked questions.


The .220 Swift was released by Winchester in 1935 and was developed as a wildcat of the 6mm Lee Navy cartridge.

The cartridge is considered a semi-rimmed bottleneck cartridge and uses a large rifle primer.

The 22 Swift is a smaller cartridge than the 5.56/.223 NATO round that people often compare the Swift to.

.220 Swift was one of the standard calibers offered in the original Winchester Model 70 bolt action rifle and continued to be until 1964, when the rifle was discontinued. The Model 70 was reintroduced in 2009 and the .220 Swift was not offered in the lineup once it was reintroduced.

Purpose of .220 Swift

The main purpose the Swift is used for today is varmint and/or small game hunting.

However, there is some controversy surrounding the 220 Swift since it is such a small caliber round. Many claim that the round shouldn’t be used for deer hunting. Some states have gone so far as to outlaw the cartridge for Deer hunting.

The claim is that the Swift cartridge only wounds deer if the shot placement isn’t near perfect and that most hunters can’t take shots that would incapacitate the deer more quickly.

This leads to the deer suffering when a larger caliber round would have otherwise neutralized the deer and allowed for a larger margin of error for shot placement on the deer’s vital organs.


The .220 Swift was the first factory rifle cartridge, sometimes called “mainstream,” to have a muzzle velocity in excess of 1,200 m/s.

That might not sound like much in the 21st Century, but the Swift was extremely impressive in 1935.

  1. Fact check. The Swift case capacity is considerably greater than the 5.56/.223.
    As regards the Swift and the .22-250 velocity comparisons…they are so close as to be
    disregarded and in some instances the same bullet is loaded to higher velocity in the Swift than the .250 by the same manufacturer (Nosler).
    As far as reloading goes, the .250 is a little easier but both cartidges gain if the are given the Ackley Improved treatment. Case stretching and neck thickening are virtually eliminated and
    they gain useable if unnecessary case capacity.
