What is this Blackhorn powder I keep reading about? I always used Pyrodex RS until the 777 came out. 777 is much easier to clean up. I had a .45 cal barrel on my Encore last year & the best I could get at 100yds was 4" groups but T/C had a problem with the rifling in some of the .45 barrel. Wrong twist rate. So I swapped it back to my LGS for a new unfired .50 & I haven't shot it yet but my intentions were to run 777 in it (loose powder not the pellets) unless this Blackhorn stuff is better. Also I'm gonna check into a local guy who's making smokeless muzzleloader barrels for the Encore that they say are getting crazy velocities & one hole groups at 100yds. Not sure the $$$ yet but I hear they are a little pricy.
