Went to the range again yesterday. 3 times the rifle did not fire. I knew I had put powder in it. Not sure what the problem was, but solved it by taking out the nipple and putting powder behind it. Put nipple back in and it fired all 3 times. Slowly but surely I am gaining confidence in how to fix things. Have only seen that one other BP shooter at the range, so if there is a problem, I am pretty much on my own.
