I have a Knight American that will not group. I have used Power Belts, Sabots and two or three other bullets. I have tried Pyrodex, Triple Seven and Americcan Pioneer Powder. The best that this gun will do with 90 grains of American Pioneer and 245 grain Sabots is about two feet at 100 yards. The same with Power Belts. The bullets were all over the target.
I finally got the gun to group about three inches with Harnady 385 grain Buffalo Bullets and 90 grains of triple 7.
What gives? Can anyone offer any suggestions? Are the Knight Americans this sorry of a muzzle loader?
