The .220 Swift that I am shooting now is my favorite varmint rifle. The Winchester brass that I bought bulk fits the rifles chamber just right. The loads that I shot last season were with this new unprimed brass and they were as accurate as any rifle that I have had to date. You can't fire full power loads from an fire formed chamber until the brass is fired once.
Since it's agreed that both cartridges have about the same performance the Swift is just a lot less bother. Of course for anyone who has not owned a "AI" chamber then of course I can understand the curiosity.
Over on AR "Pecos 45" called the Swift "The closest thing to a death ray that one can legally own"
