Someone mentioned about 3.8gr of 231 in one of my threads. I've had some of those loaded for some time and just loaded up some using 4.0gr of 231.
Truth be told, I've got a number of different powders and am trying to consolidate. I'm loading up 5 rounds each of varying powders and weights to see what I like. Problem is trying to get out and shoot 'em.
Are you already set up to reload?
