(Fig. 38)

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

The bullet consists of an envelope (a) of steel coated with cupro-nickel (S.M.I.) or cup-ro-nickel (B.P.D.), copper sleeve (b) and a steel core (c) in a lead sheath (d). The nose portion of the copper sleeve is filled phosphorus and the envelope is pierced with four holes on the ogive, so that at these points the phosphorus is protected only by the cop-per sleeve. This presumably permits collapse and distrubution of the phosphorus on im-pact with a sufficiently rigid material. The methods of closing the base of the bullet vary, but a typical example is shown. In each method there is a solder seal.
