I am going to mess with the 338 Win Mag and the 275gr Speers I have. I have RL22 and IMR 7828. I will be using CCI250 primers and be shooting them in a 24" barreled M70. I will also be using Winchester Cases, if it matter. If anybody can run a Quickload, I would appreciate it. I think 64k PSI is the roof for the 338 Win Mag. Scotty
