Sub-caliber projectile for hunting shotguns, comprises projectile body with axial pin which is forced into air chamber upon impact to generate shrapnel

摘要

The projectile (1) is composed of a body divided into a front part (2) and a rear part (3), the latter being hollow. In the front part is embedded and fixed under pressure an axial rod (4) which terminates in a hard tip (6) located towards the front, which is conical in shape and terminated in the form of a cap (7), this tip (6) closing the front end of an air chamber (5) set axially in the front part (2) of the body (1) of the projectile, in such a way that when the projectile impacts, the tip (6) is displaced towards the inside of the chamber (5), which it causes to be compressed, thus converting the projectile (1) into pellet. The body of the projectile (1) is cylindrical and the helicoidal external grooves, like the body of which they form part, are made of lead with a high antimony content, and due to their remain intact when fired, a fact which, in combination with the hollow rear part (3), provides the trajectory with a great degree of precision. For loading in the firearm, the projectile is arranged within a container, which retains it and acts additionally as a shock-absorbing element and stopper for the gases generated on firing.
