thank you is there any info on this like load data or where to get dies and reamers and such

M.O.A, not alot of information just one load 60gr/4350 with 174gr bullet @ 2950fps didn't list who made the 4350 or bullet. If you look at Nolser data for the 7mag their max load with 175gr bullet is 2970fps,Hornady has one load over 2900fps,Speer also has one load.

Hard to say what a 7magAI would do today.

get a copy of P.O. Ackley's reloading manual (2 volumes) and there should be some data for what you are looking for. you will also find that there very little new in cartridge design although some of the powders today weren't available back then
