ABSTRACT:
A firearm for firing cartridges (2) which may in at least one embodiment fire caseless cartridges (2), having a barrel (1) pivoting around a pivot point (11) from a firing position to a loading position, and back to the firing position. A fixed wall (16) is positioned behind chamber (19) when barrel (1) is in the firing position, which absorbs the recoil of a fired cartridge (2). A plug (6) may be used to seal chamber (19) when firing caseless cartridges (2). The pivoting movement of barrel (1) may be activated against spring (4) by gas pressure from a fired cartridge (2) escaping from a hole (3) in barrel (1). Residual gas in barrel (1) may be used to move rammer (7) against spring (8) and rammer (7) then chambers a cartridge (2). Barrel (1) then returns to the firing position.
