HISTORY: The 220 Swift is based on Lee Navy necked down to 22 caliber. Introduced by Winchester in 1935 and discontinued in 1964 with the release of the 225 Winchester. The Swift is a high performance 22 cal with a fair share of controversy centered around barrel life. Improvements in barrel steel and slower burning powders help to prolong the barrel life of the Swift.


Brass case mouths MAY not be perfectly round from the manufacturing process, this can be corrected by running brass through the size die (always recommended) prior to loading. Residue from the annealing process may leave a stain on the case neck that can be removed by tumbling. Annealing involves rapid heating then cooling to impart the shell cases with the proper hardness to securely hold bullets in place and provides flexibility to expand and contract through multiple firings handloaders expect.
