RE: White Shooters...
The powders I most commonly use in my 3Whites are, Triple Se7en 3f, Goex 3f, Swiss 3f, and Pyrodex P. For conicals I load 70-90 grains depending on which powder. A sweet load is 70 grains of Triple Se7en 3f, a wad and a 500 grain Bull Shop Conical. Lots of powder and accuracy is exceptional.
Swiss is a powder I buy when I get another case of black powder. I get a couple pounds and it is like a special treat to shoot it. But once I run out, I go back to the Triple Se7en for the most part.
