was loading 15.9 gr clays, 7/8 oz shot in rem sts hull win primer and waa12s wad (which i have 6000).Alliant does not have a load for that wad for 7/8 and told me i would have to load 1oz. and Im afraid to try it.
The one load I was loading called for 17.6 grns. on both. They however were different bushings. So, that is pretty close.
