Right now my T/C New Englander is shooting 4 inches high at 50 yards. I am shooting a .490 roundball with 90 grains Pyrodex RS. Anyone know the Muzzle Velocity of this combo and where I might be at 75 and 100 yards? I'm asking because I am not sure if I can get back to the range before I go out for the ML season in a few weeks.
