Jack, you learned something all ways a good deal. One time I was checking out the bore of a Jonathan Browning Mountain Rifle with a brass bore lite. I turned it on and dropped it in, it stuck. Didn't know they had a tapered powder chamber. Unscrewed the nipple and put some 3fg in there reinstalled the nipple, capped it and shot it out. Now I use Thill bobber lights or the archery nock lights and no more problems. MB
It’s called a patent breech. Original Hawken rifles had patent breeches.
