US Cartridge, 57mm Canister, T25E5
This canister cartridge is fired from 57mm recoilless rifles for antipersonnel effect at close range.
The cartridge consists of a perforated metal cartridge case crimped to a cylindrical canister projectile. The cartridge case contains a polyethylene liner which is loosely filled with propellant and is equipped with a percussion primer. The primer ignition tube extends through the length of the propelling charge. The canister case is loaded with 154 or 176 stacked, cylindrical steel slugs. The thin steel case has four equally spaced slits extending from the nose to within 1/4 inch of a pre-engraved rotating band near the base. The canister is closed at the front by crimping and welding to a steel disk, and at the rear by a heavy steel base.
