The LMDE Practice Cartridge is supplied in a box of 26 including any required consumables. The LMDE is operated using a bespoke electrically initiated Practice or Service cartridge. Each batch of cartridges are ballistically tested to ensure correct and consistent performance. The cartridges are supplied in multiples of 26 (Practice) and 18 (Service) packaged within an M2A1 container complete with all consumables. The Practice cartridge limits operating pressure and avoids barrel damage such that operational equipment can safely be used in training underwater. NSN: 1385-99-410-5868
