[QUOTE="Bart B, post: 1151781, member: 5302"] With the speed 50 and 60 grain bullets will leave a 220 Swift, I think best accuracy will be with a 1:14 twist as 70 and 80 grain ones would also do well with that twist. Note the little 222 Rem was the accuracy ticket in 1950's benchrest wins shooting 50 and 52 grain bullets in 1:14 twist barrels. They spun about 154,000 rpm. The Swift will spin them about 206,000 rpm from a 1:14 twist. [/QUOTE]
