Re: Ramshot -vs- others:
I'm another Hodgdon's fan, and I love their Extreme powders (Varget, H4350, etc.) but I hate sticky powder measures from extruded powders. I've used Xterminator and Tac in the .223 and liked them; I'm getting set to try Hunter and Magnum in some other calibers (6.5-08, eventually 6.5-284). The last .308 I had didn't particularly care for Tac; other people love it.
