A friend of mine is throwing around the idea of getting a new barrel for his 22-250 as his barrel is on its last legs. He is debating going with a 18” barrel to make it a short handy calling and truck gun. We can’t run suppressors here so that part doesn’t matter. In a short barrel does anyone know if there would be much gain in velocity going with a 22-250 AI vs the standard 250. How much faster would it be than a 223 AI. He is also debating going with a 8 twist to shoot heavier bullets but if fur prices ever come back he is wondering if he would still be able to shoot his old Speer 52 gr hp’s out of a 8 twist. Sorry for all the questions but I don’t have much experience with the short barrels in a 250.
