So I measureda factory, unfired, 30.06 Remington case that was loaded and got 2.4760. So, I trimmed my cases to 2.4760. NOW, for S&Gs I decided to look it up online. Well max length is 2.49 and minimum is 2.48. So the internet says. Did I just destroy 20 cases? I know they will stretch after they are fired but.......is a .004 difference too short? Hope I dont annoy anybody with my elementary questions. Thanks.
