A shameless plug here- I saw that Graff and Son is offering their own house brand of black powder, and decided to give it a try. Ordered 25 pounds of 2F and 3F, which arrived last week. Gave the 3F a try in a 1861 Navy and in my .36 cap and ball rifle. Shot every bit as good as the Goex I've been using since the 70's, and it's only $14.99/lb. At this point I'm sold on it.

Now to try the 2F in some 12,16,and 20 gauge loads.

Porosonik.

I tried some of their 3f in my 38-55 and didn't like it. I get Swiss 3f from Buffalo Arms.
