(Fig. 39)

In general appearance this round is similar to the general British .303 inch type. The nose of the bullet envelope has four holes and 0.5 inch of the tip painted green. The brass cartridge case is fitted with a copper cap. The cap is not ringed in.

The make-up of the bullet is almost identical with that of the blue-tipped bullet described above, but the nose of the copper sheath is filled with two composit-ions. In the tip is a small quantity of magnesium and potassium chlorate. Behind this and surrounding the nose of the core is aluminium and lead oxide. Presumably the first mixture acts as an ig-niter to the thermite type of composition behind it.
