[QUOTE="Trickymissfit, post: 432478, member: 25383"] I'd personally forget the .220 Swift, and go strait to the 22-250 AI. Not any real difference between them and the cases are easier to come by as well as die sets. You can fire form factory loads in the Ackley chamber. Secondly I'd want a minimum of a 1:11 twist barrel for the 60 grain bullets. I've shot them in a 1:12 twist barrel at near max loads with a 22-250, and they really need just a little more spin. Thirdly, there is absolutly no need for a 28" barrel in that small of a case no matter which round you choose. A 26" would be the max, and really a 24" will do just fine; plus group tighter. Also when thinking of 500 to 600 yards shots your really looking at the bullets in the 70 grain and heavier area, so you might want a 1:8 twist barrel gary [/QUOTE]
