109 ABSTRACT An apparatus for loading shotguns or rifles to capacity in one operation by the use of a pre-loaded portable tubular magazine (2) which can be locked inside a rigid steel guide tube (6) connected to the firearm in place of it's conventional tubular magazine. The portable tubular magazine (2) comprises a rigid steel tube capped at one end and tapered at the other to contain a magazine spring (15) and cartridge pusher (16). Cartridges (17) are inserted over a spring loaded cartridge retainer (18) and are released inside the guide tube (6) when the cartridge retainer lifter (9) is raised by ramps (10) at the end of a slot (12) which forms a channel in the guide tube (6) for the cartridge retainer housing (21). The fore end (7) fitting over the guide tube (6) is similarly slotted and is connected to conventional slide bars (8). At the front end of the guide tube (6) limiting the forward travel of the fore end (7) a two piece barrel clamp (3) incorporates mounting brackets (4) for lock levers (5) having two laterally spaced teeth. When the lock ring (14) on the portable tubular magazine (2) engages the front tooth the cartridge retainer lifter (9) is clear of the lifting ramps (10) and cartridges are not released until the ring (14) engages the back tooth in the fully seated position . In this position it is possible to load cartridges in the conventional manner.
