So....Ive got the 250 itch lately. Ive been considering AI or the basic cartridge. I do not reload yet so this is merely for educational purposes. Has anyone tried necking down a .270 case to recieve a .250? In my mind it sounds like fun. Or maybe an AI version would be better? Who knows? Not me! Maybe a waste of powder for the performance and maybe even a barrel burner, but I am just curious. Lemme know what you think!
