[QUOTE="TOM H, post: 386065, member: 306"] There a reason you haven't reach 1.902". Your blowing the case body wider and moving the shoulder forward as most Ackley cases do. Your just reforming the case to a different dimension and that comes from case length vs stretch the brass. My 22-250AI brass length is 1.890". I think Nolser has a diagram maybe Sierra does also on the 22-250AI case that they have loading data for. My 22-250AI dia at the start of the shoulder mikes .454" vs .413" on a new Win 22-250 case and the case neck length for the AI is .250" vs .248" for 22-250. You might want to get a reamer print from your gunsmith to confirm that case length. My gunsmith gave me a factory 22-250 case fired in the AI chamber as he has with some of the other AI rifles he chamber for me. [/QUOTE]
