Took the gun to the range this weekend. Started out with 100 grains pyrodex (2 pellets) using the TC Shockwave 300 grain sabot bullet. First 3 shots at 25 yards went through the same hole. Moved back to 50 yards and had the same results. The only thing I can figure is the guy I bought it from didn't clean it well or was using different bullets that the barrel didn't like. Either way, I got one hell of a deal for $375.00. Thanks for all the help. The loading and shooting advice from this board has been invaluable.
