RE: 777 Pellets vs Pyrodex Pellets
The better-buy in pellets is Pyrodex. I read alot more accuracy complaints - alot more hangfire complaints with 777.
For loose powder application, 777 FF/FFFis the best of the two. Pyrodex P. (pistol/FFF) is the only one I recommend in the Pyrodex family. It's stronger, cleaner & faster burning.
For pellet application, Pyrodex is best of the lot.
