Anyone have any load data for 357 Magnum? I tested 15.0, 15.5, 16.0 and 17.0 grains of H110 in a Smith and Wesson 686 Pro Series 4 inch barrel and groups were all over the place. Hornady 158 grain XTP's were used along with CCI small pistol magnum primers. Crimp die was snugged down when it touched the case mouth and turned an additional 1/4 of a turn.
