Buy the absolute best you can afford. Most of the game is mental anyways. Showing up to a match with what you think is the best of the best goes a long way.
One of the best performing 9 major powders out there. It's also very dirty but that didn't bother me. Depending on the lot I was between 9.6-10gr with a 124 jhp at 1.168. This was good for 173-174pf in a fullsize gun and no holes.
