Ladies and gentlemen, I have been searching for a recipe for the .308, 208 Gr. A-MAX bullet for the .30-06. I started to just do some testing myself. Conditions were 65 degrees, pressure 30.01, altitude 4950 ft. My start load was 50 Gr. of IMR 4831. Muzzle velocity was 2375. The Best load for my rifle was; 51 Gr. of IMR 4831 I hope this info helps someone out there, who is like me, who wants to shoot some long range with the .30-06!
