I've been capitalizing on the 30-06 case volume for many years, and often get scorned by the purists.
I'll just throw out some physics info.
Case volume comparisons.
300 SAUM - 71-72 gr give or take.
30-06 (I've measured, after fireforming)
milsurp - 68 gr
Rem - 69 gr
Win - 71 gr
Norma - 72 gr
If you are wondering what the hell I'm trying to say, reloading probably isn't your gig.
