A muzzle loading firearm comprising: a barrel with a bore defining a bore axis, and having a muzzle end and a breech end; a frame connected to the barrel, and having a breech face; the frame being movable between an open position in which the breech face is away from the breech end of the barrel, and a closed position in which the breech face abuts the breech end of the barrel; a breech plug removably attached to the barrel and having a rear surface defining a central primer receptacle; an extractor connected to the barrel and having a primer-engaging portion adjacent to the primer receptacle; the extractor being operable in response to movement of the frame to the open position to move the primer-engaging portion in a first direction away from the breech plug to extract a primer; and the primer-engaging portion of the extractor being movable in a different second direction such that the breech plug may be removed without removal of the extractor.
