US Cartridge, 20mm HE, HEI, Mk 3 Mod 1 - 64




The explosive filling of the HE projectile is press loaded in three equal increments. The HE-I projectile is similarly loaded, but the first increment consists of an incendiary mixture, the other two of HE, either tetryl or pentolite.

This round is also issued B.L. & P., with an inert filler and a dummy nose cap.

The many modification numbers are to distinguish between products from different contracts.
