Abstract (en)

[origin: WO2004085953A1] Described herein is a round of ammunition for firing from a gun having a rifled barrel, especially a small arms weapon. The round comprises a body core (7) which has a plurality of knurl lines (9) and associated grooves (6) formed over a portion of the body core (7). Jacket material (11) is provided over the body core (7) such that the inner diameter (10) of the jacket material (11) makes contact with the knurl lines (9). During firing of the round, the jacket material (11) deforms into the grooves (6) formed between the knurl lines (9) enabling the rifle engraving to take place with a substantially reduced axial force.
