You guys are going to love the black mag 3 . Its the best Ive tryed between goex , pyrodex and 777 . One word of advise start with a low charge . 90 grains of black mag to me is like 110 or 120 of 777 .I have heard that the pioneir powder is weaker than 777 , the opposite is true of black mag , they got the mag part of the name right . I got real good accuracy out of it and the fouling is a white waxy residue that cleans easyly
