as tac said.....
i only shoot mine between 6 and 18 shots per session with 25gns swiss bp /wad /.457 ball and have no issues....only thing that can happen is a spent primer cap can drop into a crevice and stop cylinder rotation lol.
i always grease my cylinder pin with imperial wax or sometimes wonderlube if i grease over balls( oooooh errrrr ) and have it left on my fingers.
what bp do you use?
