I'm using the TC short nipple Rock Fish. It works fine with Pyrodex, but I need to slap the lock after dumping in theT7 to make sure some gets under the nipple. If I don't, I will sometimes get a hangfire with T7
Same here that is why I switched to 3f especially in cold weather. @f works fine most of the time in warm weather provided you get some out towards the nipple. My routine eventually become to drop 5/10 grains tap and drop the rest - never had a problem with this routine...
I was dinging around with my GM-LRH the other day runing fiber optic light into the bore from the clean-out screw - i was kinda surprised the beam and optic came our on top of the load instead the side or bottom.
