| GERMAN 7.92/13 mm A.P. TRACER LACHRYMATORY CARTRIDGE |
| (7,92 mm Patr. S.m.K. Rs L'spur) |
| (Fig. 3) |
|
This round is fired by the German 7.92 mm Anti-tank Rifles Pz.B. 38 and Pz.B. 39. |
|
The round consists of a necked brass case fitted with a black tipped bullet. The cap an-nulus is varnished red. According to normal German identification, these marks indicate an A.P.T. round. |
|
The case appears to be a 13 mm one necked down to 7.92 mm and has an unusually deep extractor groove. The head of the case is very thick and an interesting feature is the thickening of the wall of the "small cone" as the diameter is reduced towards the neck. This may be incidental to the coning but will help to withstand the action of the gases at this restriction. The cap is secured by three stabs. |
|
The propellant charge consists of 200 grains of powder, apparenty graphited N.C.T. |
|
The bullet consists of a steel envelope coated on both sides with gliding metal and con-taining a tungsten carbide core in a lead sleeve and a tracer cup. A cylindrical cavity in the base of the core contains a 4 grain lachrymatory pellet. The tracer consists of a steel cap coated with gliding metal and containing a composition which produces a white trace which might be expected to last about 700 yards, allowing for the very high velo-city this bullet will probably have. The base of the bullet is sealed by the turnover of the envelope on to a pink celluloid disc supported by a brass washer. |
| The mouth of the case is coned into a flat-fronted cannelure on the bullet. |
