Body of shot unpainted except below the driving band, where it is laquered black. |
| (b) | The body is marked with a 0.2 inch red band above the driving band. |
| (c) | The weight of the tungsten carbide core is 960 grains. |
| (d) | The total weight of the shot is 1,555 grains. |
| (e) | The propellant charge consists of 679 grains of N.C.T. |
| (f) | The colour of trace is white, changing to red. |
| (g) | The weight of the complete round is 4,300 grains (approx. 9 oz. 13 dr.) |
|
The percussion cap in the base of the case is of steel and the cap annulus is lacquered red. |
|
The shot consists of a duralumin body which has a conical head and contains a tungsten carbide core, and is fitted with a tracer screwed in at the base. The body is increased in diameter at the shoulder, and is fitted with a copper driving band and cannelured near the base. The armour-piercing core has a V.D. Hardness figure of about 1,700, and the composition, by analysis, is as follows: |
|
Carbon |
4.2 per cent. |
|
Tungsten |
92.0 per cent. |
|
Nionbium |
2.4 per cent. |
|
Iron |
1.2 per cent. |
|
Cobalt, nickel, titanium, silicon – trace or oil. |
|
This composition differs from previous type in that an iron bond and not a nickel bond is used. The head of the core is ogival and is struck with a 0.7 inch radius |
|
The tracer consists of a mild steel body, which is screwed into the shot behind the A.P. core, and contains the tracing and priming composition in a cavity in its base. The cavity is closed by a transparent disc secured by ringing. |
| The following stampings have been met with:– |
| "Aux 1 K 41 WaA 109" on the shot 2 inches above the driving band. |
| "Avu WaA73 41 6h" on the base of the case. |
