I'm trying to use up a 8# jug of Winchester 296 I bought when powder was scarce. I normally used Alliant 410... I'm using AAHS hulls, Winchester 209 primers and Claybuster 5050-410HS wads. The recipe calls for 15.3 grains of powder and I'm averaging 15.5 grains on dump... However, my shot dumps are light @215 grains. A 1\2 oz equals 218.75 grains... has anyone ever modified their shot bushing on a PW 800+?
