Had a shot with a Pedersoli Sharps 45-70 single shot on wed, very impressed, it was loaded with Pyrodex, thinking might get one but ? can I load it on my Lee press and is the action called a Rolling Block ? it had a short lever on the trigger guard which opened the action and pulled the shell out about 1/2 inch, it had an internal hammer not on the outside like a percussion musket, the owner called it a Sharps Buffalo gun, it was too busy to ask more questions, cheers Tezz
