The cartridge is used in the 7.62 cm Pak 36 anti-tank gun. The overall length of the complete round is approximately 39.2 inches, and it weighs 28 lb. 4 oz. The shell is pain-ted black and stencilled in red, and also a red band painted immediately in front of the driving band. A white tip 1.58 inches long on the ballistic cap readily distinguishes the round from that used in the 7.5 cm Pak 40 gun which fires a round with a cartridge case bearing a similar case model number stamped in the base. The case is stamped "6340 St. Pak 44 Rh."

The filled shell with fuze and tracer weighs 16 lb. and the design is similar to the 7.5 cm Pak 40 APCBC shell illustrated in Pamphlet No. 7, page 51. The bursting charge consists of 9 1/2 drams of cyclonite wax 90/10. The single driving band is of the copperiron type. The piercing cap is soldered to the ogival part of the body, and the ballistic cap, approxi-mately 0.06 inches thick, is attached to the penetrative cap by a circumferential deposit of weld metal, the excess of which is removed by grinding.

The base fuze Bd.Z. 5103* with gaine is described in Pamphlet No. 4, pages 14 and 15, which includes an illustration in Fig. 8.

The case is similar to that of the APBC/T Shot round described in this pamphlet, except that the base of the round examined was stamped "6340 St Pak 44 Rh" and apparently it was intended originally for a Pak 44 equipment. The case is stencilled in red "Für Tropen, P.T. + 25° C" and, in black, particulars of the propellant charge identical to that stencil-led on the bag containing the propellant charge.

The propellant charge weighs approximately 5 lb. 7 oz. 7 1/2 dr. and consists of dark tu-bular sticks of Digl. type 24.3 inches in length, with a mean external and internal diame-ter of 0.175 inches and 0.056 inches respectively. An analysis of the propellant shows it consisted of nitrocellulose 63.44 per cent, diethylene-glycol-dinitrate 25.79 per cent, ethyl centralite 9.60 per cent, potassium sulphate 0.91 per cent, and graphite 0.26 per cent. The charge is wholly contained in a knitted fabric bag with an igniter in a stitched pocket at one end. The bag is stencilled in red "Für Tropen" and in black 7.62 cm Pak 36. 2,480 kg. Digl.R.P. – G0 – (625 – 3,8/1,3).

The igniter consists of 20 grams of Nz.Man.N.P. in the form of chopped cord. An analysis shows that it consists of nitrocellulose 92.06 per cent, diethylene-glycol-dinitrate 7.10 per cent, and diphenylamine 0.84 per cent.

The percussion primer C/12 n.A. is similar to that described in Pamphlet No. 4, page 10, and illustrated in Fig. 4, excepting the cap composition which consists of barium nitrate 50.9 per cent, lead styphnate 22.2 per cent, anti-mony sulphide 7.2 per cent, and calci-um silicide 19.7 per cent, and possibly a very small quantity of tertazene as a sensitizing agent. The weight of the composition is 0.44 grains.
