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.

I found this info at http://www.reloadbench.com/cartridges/220.html.

That site has a lot of good info on most common calibers. I found it a couple of days ago and have read up on a few calibers I was curious about. Anywho I'm glad I could help you out Killer. :thumb

I remember as a kid my Dad using this caliber to plink at those tiny Excedrin bottles at 300 yrds....love it! Accurut and deadly...PRO thought it was alittle small when he killed a buck with it in 1989
