ABSTRACT:
A practice ammunition includes a propellant case having a case body; a circumferential mouth part; and a circumferential shoulder connecting the case body with the mouth part. The shoulder tapers from the case body toward the mouth part. The practice ammunition further includes a bursting body having a rear part fitted into the mouth part. The rear part is provided with a circumferential groove including a relatively deep frontal groove zone and an adjoining, relatively shallow rear groove zone, whereby the groove is stepped as viewed in the direction of the longitudinal axis of the ammunition. There is further provided a holding ring so dimensioned that it is compressible such as to be fully receivable within the deep groove zone. The holding ring surrounds the rear part of the bursting body and is clamped between the rear groove zone and the inner surface of the shoulder, whereby the holding ring assumes a wedged state. In such a wedged state the holding ring has an outer diameter which is greater than the outer diameter of the rear part measured at a location axially rearwardly of the groove and is greater than the inner diameter of the mouth part.
