There is nothing more fun than shooting a black powder rifle with a long tapered throat with out using a blow tube or wiping stick by just open the breach extracting the case drop in a new round close the breach and shoot again and again busting rocks or bowling pins[smilie=w:
With the tapered chamber you can do this using a GG or patched bullet at groove diameter or under and get very good results.
I have a old Pedersoli Quigley rifle I re cut the throat and I have a great time using the barrel sights and doing just this out to 800 yards.
