M309 10mm Caseless

The 10×24mm Caseless, designated the M309 in United States Colonial Marine Corps service, is an American-made caseless rifle cartridge notable for being the primary ammunition used by the M41A Pulse Rifle and its variants.

The round consists of a 210 grain, steel-jacketed and explosive-tipped round embedded within a rectangular propellant block of Nitramine 50.

To load bullets into magazines simply put a magazine and a bullet into a crafting table and it will load that round into the magazine. Dragging the magazine onto the crafting grid subsequent times will result in more bullets being added up to a a maximum of 99 rounds. Factory specs recommend only loading to 95 rounds to prevent jamming.
