The first 220 Swift I ever bought was a Winchester "heavy Varmint", Winchester short push feed action in a HS Precision stock.
I love this rifle but found out very quick that the magazine is useless, I have always used it as a single shot.
If you want a repeater you need a long action.

most of the brass issues keith mention's can be mitigated (not eliminated) using Norma brass, I will never use Win. brass again.
I must admit for most of my long range 22 cal chores I use a 22-250AI but still have love for the Swift
