I finished my TC Hawken and have gone shooting a few times now but keep having a problem of my first shot not firing. I do the slap on the side after dumping powder but for the first shot it doesn’t seem to work. I’ve just poured a couple grains down the nipple and she goes. Today it didn’t so I pulled the ball, took off the barrel, and the nipple was clogged. I clean my barrel after shooting but do I need to remove the nipple and clean it as well?
