The Canister M1 was developed for the M1916 Gun. Its purpose was to spray personnel with lead balls at close range.
The canister is nothing more or less than a can filled with 38 lead balls. The case is provided with 3 longitudinal slots. A raised bead around the lower portion of the case stops the projectile from seating too far into the cartridge case. It should be noted that the projectile consists entirely of inert materials and does not require a fuze.
Canister M1 will probably be found in the field assembled to Mk IA1 Cartridge Case primed with M23A1 Primer. Some rounds may be found, however, with Mk I Cartridge Cases and Mk IIA1 Primers.
Propelling charge. FNH powder contained loosely in the cartridge case.
Projectile. The canister is nothing more or less than a can filled with 38 lead balls.
