So I went and shot my muzzleloader today and sighted it in for 125 yards. It's about 2 inches high at 50 and 100 yards and about 4 inches low at 150 yards. I use 2-50 grain pyrodex pellets and a 300 grain Hornady XTP bullet wrapped in the fitting .50 cal jacket. Do you think that I should try shooting 150 grains to slow the rapid fall past 150 yards? What combinations do you guys shoot that you think works well and patterns good?

P.S. - I shoot a Knight Disc .50 cal with a 3x9x40 Nikon Prostaff.

Thanks!
