Looks like you're gonna have fun playing with the stuff anyway. May turn out your rifle don't like it...but you'll have clean hands. I've used it with a variety of loads. Shoots one ragged hole at 20 yards with my .54 "rabbit" load of 30grs. 2f Goex. Shoots good at 100 yards with 70grs. of 2f Swiss. Looking forward to hearing your other tests.
