I like Trail boss powder. It works well with cast bullets. I load 45acp, 45colt, 7.62 Nagant, 38sp and 30-30 with it. You just mark the case were the bottom of the bullet will be when seated. Fill the case to the mark weight it this is your max load. 70% of that is your starting load. IMRs link http://www.imrpowder.com/data/handgu...ss-feb2005.php Burns clean and is accurate in my guns. Only use it with cast bullets in handguns and don't compress it.
