'''10x24mm Caseless''' is a type of [[ammunition]] for firearms. It is considered to be a <span style="color:#AA0000">'''(R)'''</span>ifle caliber, although a very special one.
This cartridge was designed for the highly advanced [[M41A Pulse Rifle]], perhaps the rarest production weapon in the Mazesan artifact firearm. Like with [[4.73x33mm Caseless]], this cartridge requires specialized, dedicated machinery to produce. Although ammo factories do produce regular batches of ammunition, they are both rare and relatively small; no more than a few thousand rounds per year.
10x24mm is pronounced ''ten by twenty-four millimeters''.
