.303" Ball ammunition:

This is the first version of the approved .303 ball ammunition, a rimmed case with a total length of 56mm. The case has a boxer primer (seperate anvil and one firehole) and is filled with 71,5 grains of compressed blackpowder. The bullet is round nosed with a lead/antimony core and a cupro nickel envelope.

The blackpowder mk II has a slightly thicker envelope with a larger turn over at the base, to avoid the separation of the core and the envelope.

The cordite mk I has a propellant of 31 grains of cordite instead of blackpowder. The headstamp has the code letter "C" included.

Unlike the three cartridges mentioned above, the Cordite mk II has a berdan primer. (the anvil is part of the case with 2 fireholes)

The ball mk III has a bullet with the front of the envelope pierced. A metal cup is placed in the hole with the front edge turned over the envelope. The ball mk III was almost immediately withdrawn after approval making it a very rare cartridge.

The bullet of the ball mk ÍV has a different nose cavity and a pure lead core.

The bullet of the ball mk V has a lead/antimonyy core to avoid squirting of the core at the rear of the envelope.

The ball mk VI has almost the same bullet as the mk II with a little thinner envelope.

The bullet of the mk VII was pointed, with either cupro nickel, cupro nickel clad steel, gilding metal or gilding metal clad steel envelopes.
