The ammunition used in the Pz.B. 38 and Pz.B. 39
(antitank rifles) is of the armor-piercing type. The
round itself can be identified by the large cartridge
case, necked down to take the 7.92-mm (.312-inch) bullet.
The German labels distinguish this ammunition
from the regular 7.92-mm rifle and machine-gun
ammunition by the words "Patr. 318" in front of the
distinguishing "S.m.K." Labels having the distinguishing
"Rs." have a small amount of tear gas in the bullet.
b. Patr. 318 or Patr. 318 S.m.K.
This is the regular armor-piercing ammunition for
the Pz.B. 38 and Pz.B. 39 antitank rifles. It consists
of a large cartridge case (like the U.S. caliber .50
cartridge case) with a small projectile of 7.92-mm
(.312 inch). The projectile has a gilded metal jacket and
a tungsten carbide core. Sometimes it will have a
tracer and sometimes a small charge of tear gas in the
base of the projectile.
