I have a 22-250 and a 243 I'd like to have improved. And being a gun geek I love reading loading manuals of various cartridges. I know a couple manuals have 22-250 AI data but I haven't seen any "published" data for the 243 AI. So is there a book with close to all the Ackley cartridges? Or maybe a legitimate website that lists them or a method of working up loads? I just get nervous using online loading data from "Billy Bob" who I don't even know. Also I just bought a Forster neck sizer for 22-250, will this same die work for sizing the neck on the 22-250 AI? If not no worries because I'm inheriting a couple 22-250's that I dare not improve.
