(Fig. 11)

The cartridge is used with the 7.62 cm Pak 36 (r) (field gun of Russian origin) and inclu-des a case and primer also of Russian origin. The projectile is German.

The overall length of the round is approximately 23.5 inches, the capped projectile being painted black.

The shot with its ballistic cap is 9.5 inches in length and weighs approximately 9 lb. The steel body is screwthreaded to receive the aluminium alloy ballistic cap and is fitted with a driving band of soft iron covered by a band of copper. A cannelure for the attachment of the case is formed behind the driving band and a hole formed in the base is screwt-hreaded to receive the core holder. The cylindrical holder is of steel and is screwed into the base of the body from the front. Two recesses are formed in the holder, one at the front end to receive the armour-piercing core and the other at the base, which is screw-threaded to receive the tracer. The diaphragm between the two recesses is bored cen-trally to permit the escape of air when the core is inserted. Details of the tracer are not availab-le.

The armour-piercing core is 1 lb. 15 oz. 3 dr. in weight and consists of tungsten carbide plated with nickel. The base end of the core is chamfered to facilitate pressing into the holder. The marking "249E" has been found on the core in black.

The core and its holder are surrounded by a sleeve of moulded plastic which fills the space between the body and these components and has an ogival head within the ballis-tic cap. The plastic has a fairly high shock resistance and the design and construction of the projectile provides a rigid assembly of the components during flight without impeding free egress of the core on impact.

The brass case and the percussion primer are the same as those described for the A.P.C.B.C. round. Details of the propellant type are not available.
