Varget is good as well. I bet a good portion of 308 shooters use either RL-15 or Varget.

Ramshot Tac is also nice. One big advantage of TAC (at least for me) is that I can't really get stick powders to throw consistantly enough from my RCBS measure to not weigh or trickle up each charge. TAC is a ball powder and meters very well for me. So if I was going to do lots of shooting I might choose TAC for just that reason.

I found 150g 30cal SSTs to be very accurate, but fairly soft bullets.

The collection of taxes which are not absolutely required, which do not beyond reasonable doubt contribute to public welfare, is only a species of legalized larceny. Under this Republic the rewards of industry belong to those who earn them. Coolidge
