308 Gas Gun reloads

[abinok]

Im putting together a load for a friend's SR-25, essentially a AR-10 and a bit more, and im looking at IMR 4064 and 175SMKs as Federal Gold medal 175s shot pretty well today. Im looking for some suggestions on primer choices, and other powders if anybody has had good results.
Anybody?

Federal GM 210 on the primer. And also try varget. Plus you might get more responses for the gas gun on www.artactical.com or www.snipershide.com

Thanks charles, I posted over at artactical... hopefully ill get some more input.
My initial thought was the 210, or 210M, but ive read and heard that in some service rifle circles the 210 is frowned upon due to a higher sensativity to slamfires. I know that Federal refutes this claim, but when youre loading for someone elses rifle, I like to be able to present a good argument for the componets chosen. Obviously, federal uses their own primers for their own loads...
Just need some input on primer compatability... I don't load powder this fast very often [img]/ubbthreads/images/graemlins/smile.gif[/img] Ive heard 210, and the cci BR2 so far... anybody else?

46 gr. varget Fed 210m 175gr SMK win brass.
47 gr. varget Fed 210m 168gr SMK win brass.

Both of these loads went .3 in an Eagle arms AR-10T
