| Remarks |
|
This round consists of brass cartridge case, a copper cap, and a bullet whose jacket is pierced with four holes on the ogive so that at these points the incendiary composition is protected only by a thin copper sleeve. The jacket is steel plated with either copper-nickel or copper-nickel alloy. A copper sleeve, a steel core in a lead sheath, and the for-ward nose position filled with phosphorus are enclosed by the bullet jacket. The four ho-les on the ogive permit the distrubution of the phosphorus on impact. |
