CARTRIDGE RIM FIRE .22" BALL
PRINT DOCUMENT
GENERAL :
The cartridges are of rimmed type. The complete cartridge consists of a cartridge case with rimfire composition, propellant charge and bullet. The rimfire makes thus a cartridge without a percussion cap. It is rimmed out to hold the initiatory composition. The striker of the rimfire rifle is placed eccentric to the axis of the barrel, so that when the rifle is fired, it pinches the rim and thus fires the cartridge. The bullet is made of lead antimony alloy and is unjacketed. The bullet is round nosed and formed with three circumferential grooves.
