Re: .300 win mag & 208 AMAX loads?
Try some H1000 too. I found that I could get better velocity without the pressure that I got with 4350 and 4831. They are also notoriously temp. sensitive as well, whereas H1000 is not and it is amazingly clean burning.
If you're shooting under 1500 yds, try some 210 Bergers and JLK's too. I'm finding that there are times when they are grouping a lot tighter.
