US Cartridge, 57mm TP, M306A1

 

clip1485

Description

This cartridge is used in 57mm recoilless rifles for target practice.

The cartridge consists of a perforated metal cartridge case, containing a plastic liner, which is crimped to a steel projectile. The cartridge case liner is loosely filled with propellant and the cartridge case is equipped with a percussion primer. The primer ignition tube extends through the length of the propelling charge. The projectile resembles the HE round M306A1 with the same shape and pre-engraved rotating band; however, instead of high explosive filler, the target practice round contains only a small black powder marking charge. The projectile is equipped with a PD fuze. This target practice round has the same ballistics as the HE round.
