Still shooting. The mis-fires are history. Shot today, tried 110 gr. Pyrodex with Federal Bore lock, win shotgun 209 primers. 4 in group at 50 yds. 100 gr pyrodex, same result.
Cleaned out the breech plug. Cleaned the barrel well. Ran plenty dry patched too to make sure it was dry. Tried 110 gr.BH209 with Fed Bore lock bullet still 4 in group but 1st bullet by itself other 2 nearly touching but 4 in. away. Only had 2 more bullets left so figured I would do a 5 shot group. Both were close to the other two touching. So first shot a flier with everything clean. 4 inches away the next four shots are 1-1/8" group. What do you think? I feel sure I didn't pull the shot, I'm on a led sled, the works.
