[QUOTE="PddPdd, post: 3065858, member: 111799"] In theory, your nodes should be about 3% apart with regard to powder charge. So your groups for A & D seem to reflect that. If you move to the next node up ~45.3 plus or minus, you should see another tighter group and perhaps your bullet/barrel prefers to be run faster. You will need to do smaller powder increments to find the sweet spot for powder charge imo. Have you done any seating depth testing? [/QUOTE]
