Presently I am shooting 110 grains of loose pyrodex select powder from a T/C renegade with a 405 hollowpoint black belt (powerbelt) with the copper jacket. I get about a 2" group at 50 yards and a 4" group at 100 yards with a peep rear/ fiberoptic front sight. Since my personal limit on this rig is 80 yards, I feel comfortable with this set up.
