Magic Missile Cartridge (3.5e Equipment)
From D&D Wiki
Magic Missile Cartridge: This is the matching cartridge for the Magic Missile Cannon, found in the Wondrous Items section.
This cartridge holds up to 50 magic missiles (individual missiles, not charges of several). Each shot of the cannon launches 1, 3, or 5 of these missiles from the cartridge at foes. Any character who can cast Magic Missile (even from a wand with the UMD skill) can load x amount of missiles into the cartridge as a full-round action, with x being the number of missiles they can normally cast from the spell/wand/scroll. It is not uncommon for there to be spare (loaded) cartridges near Magic Missile Cannons, if they can be afforded.
