  1. Reloading M2AP - Resizing needed?

    The Ammo & Reloading Forum
    I'm reloading some old M2AP projectiles, some were machine pulled with marks, some pulled with no marks. I'm measuring most of the marked bullets at .309" on my calipers, none more than .3095, mostly around .3085. Do I need to resize these? The margin is so small I'm not sure if it's a problem...
