You know I have a 22-250 and 223 and I would have never dreamed that twist rate had anything to do with what weight bullet you would shoot. I took one look at the 22-250 brass and thought I would or could shoot up to 100 gr bullet in it. Or I would have argued that the 22-250 w/14 twist would have shot a lot heavier bullet than a 1:9 223. Really have learned a lot on this board.
