Re: Mil-surplus powder for 300 rum?
Yep, the 300 rum will do well with wc872. 104 gr on a 190 or 112 gr with a 180 will shoot sub moa in my rifle. I prefer rl25 or rl33 but this stuff is cheap, goes bang, and does a fair job at pushing a pill downrange.
I've burned wc872 in my 7rem with 175's and it wasn't as impressive. Come to think of it, the 7 rem isn't that impressive. I should have it reamed out to 7stw but I have too much brass for it yet. I'll barrel it and toss the brass when she dies.
