I really don't know anything about loading for modern semi autos.. My experience has been with the Garand M1... I do know that whatever powder used in factory 150 grainers such as Rem green WILL damage operating rods in M1s...4350 is a little too slow, and 4831 is a definite no-no..

I guess if I were loading for a 30-06 semi, I would concentrate on medium burners such as 4895 or 4064.. They are both good performers in the 30-06.... Just my humble, not-too well educated opinion..
