I have no regrets moving away from 777 powder. In about another month, I may say the same thing about moving permanently away from Pyrodex, American Pioneer and Goex/Schuetzen blackpowder.
Blackhorn 209 has a frustrating hiccup or two. But the positives early-on in my range-time with it, far-outweigh the negatives. My wallet needs to adapt to Blackhorn prices also. I cannot believe how fast I burned my first jug of Blackhorn.
There should be an ML law on banning smaller containers and higher prices combinations....lol
