These are 37MM projectiles with a pocket to allow an M183A1 point detonating artillery simulator projectile to be inserted. These fit perfectly with the 4.5″ cases on this site or any case with a 1.375″ inside diameter that is sufficiently long. We recommend using a MILC chamber and adding a bit of super glue inside the case mouth as well as a dab on the M183A1 to secure it in place.
