Deer Hunter 21,I feel your pain!Had a Knight 54 cal wolverine and experienced same problems as you sold gun to a friend thinking bad scope was problem(Trashco).He changed the scope and still we couldn' t get it to shoot a decent group.But persistence finally payed off!Many different loads powder and bullets and finally have the right combo,105 gr.pyrodex Rs and a 330 gr perssision Extreme bullet,that 5 gr.of powder made all the difference.It is possible that you have a barrel with a burr in it,check to see if every thing is smooth and burr free,you may need to lap your barrel.Also he started to line sabot pedals with lands every time and that may have helped also.CallCecil at persision Bullets and he will be more than helpful with his vast knowledge.Good luck
