This 25mm M794 Steel Dummy Round is the correct inert training and function-check cartridge for the 25mm M242 automatic cannon. It is a full-size, service-pattern dummy round built to replicate the size, weight, and external profile of live 25mm ammunition, making it an excellent piece for collectors, display projects, training setups, and restored weapons-system presentations.

The M794 was developed specifically as a non-firing dummy cartridge for the M242 Bushmaster family. In military service, it was used for weapon checkout, loading drills, crew training, and handling practice, allowing crews to work with a realistic cartridge without the hazards of live ammunition. That makes it an important part of the broader 25mm ammunition family and a correct companion piece for any M242-related display.

The 25mm M794 Dummy Cartridge

The M794 dummy cartridge, intended for non-firing use only. Its purpose was to let crews inspect, test, and practice with the M242 weapon system using a cartridge that matched the form and handling characteristics of service ammunition.

Unlike live 25mm rounds such as the M791 APDS-T, M792 HEI-T, M793 TP-T, or M919 APFSDS-T, the M794 contains:

No primer
No propellant
No tracer
No fuze
No explosive components

Instead, the M794 uses a steel projectile body and a steel cartridge case filled with inert epoxy resin, creating a robust, realistic cartridge that could stand up to repeated handling and system checks.

Technical Characteristics

For reference, the M794 dummy cartridge is documented as follows:

Type: Dummy, inert
Caliber: 25mm
Weapon system: M242 automatic cannon
Projectile body: Steel
Cartridge case: Steel
Color: Silver
Overall length: approximately 8.63 inches
