I just got a new 50 cal CVA Optima Magnum with a Redhead Epic 3x9x40 Muzzloader scope. It was boresighted at Bass Pro when I bought it. First shot it was about inch high at 50 yards, 2nd shot inch low at 100 yards, 3rd shot 4 inches left at 100 and then 4 inches right at 50. I had a steady rest and did not clean between shots. I was using 100 gr pyrodex pellets and 245 gr aerotip Powerbelt bullets. Scope is tight, any suggestions? Thanks.
