25-30MM

25–30mm covers medium-caliber military and signaling ammunition spanning automatic cannon, grenade, flare, and specialized training systems. This category includes 25 mm and 30 mm cartridges, projectiles, and components used in aircraft, ground vehicles, naval mounts, and auxiliary launchers, as well as non-lethal and signaling applications.

Items in this section include practice and dummy rounds, inert and sectioned examples, flare and parachute signals, grenade bodies, belt links, and case variants produced for training, logistics, and display. You will find wide variation in materials, color coding, construction methods, and markings, reflecting different national standards and evolving ordnance doctrine. Because many of these items were produced in limited runs or under specific contracts, this category is especially valuable for collectors studying mid- to late-twentieth-century military ammunition development and identification across multiple platforms.
