Never used this powder before, but it's all I could find, and I'm using a Lee Load All. 1 1/8 oz of shot, STS hull, and Winchester primer, WAA12 claybuster wad. The load data recommends 17.4 grains for an 1150 velocity trap load. The bushing I have in it (134) is throwing about 17.5-17.7 grains on the scale. I was just wondering if that was about right from those with more experience loading this powder.
