I don't blame you for wanting to put another barrell on that White Mountain. I had one and it was the fussiest muzzle loader I ever had. One year it would shoot great then the next year I couldn't hit the broad side of a barn with it. Then the next season it would shoot good again. I tried everything I could think of and I just couldn't get it to shoot consistent from year to year. I finaly sold it and bought a new Knight.
