Rotating, explosive sub-calibrated projectile

Abstract

A projectile (1) is composed of a body divided into a front part (2) and a rear part (3), the latter being hollow. An axial rod (4) is embedded and fixed in the front part under pressure. The axial rod (4) terminates in a hard tip (6), which is located towards the front, and which is conical in shape and terminates in the form of a cap (7). The tip (6) closes the front end of an air chamber (5) positioned axially in the front part (2) of the body (1) of the projectile. Upon impact, the tip (6) is displaced towards the inside of the chamber (5), which causes it to be compressed, thus converting the projectile (1) into pellets. The body of the projectile (1) is cylindrical and has helicoidal external grooves. The body is made of lead with high antimony content. The projectile is arranged within a container, which retains it and acts additionally as a shock-absorbing element and stopper for the gases generated upon firing.

Description

[0001] This is a Continuation-in-Part application of Ser. No. 10 / 220,339, Dec. 27, 2002, which is the National Stage of International Application No. PCT / ES01 / 00502, filed Dec. 21, 2001.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a sub-calibrated projectile (as it has a smaller diameter than the barrel of the gun in which it is used), rotating, as it rotates when it is shot at 3000 rpm and compressed air explosive as will be explained hereunder. [0004] The object of the invention is to provide shooters and hunters with a projectile capable of reaching twice the distance of all known projectiles, due to its gyroscopic stability and being explosive, with exceptional stopping power which has not yet been constructed in any world nation. [0005] To avoid deformation in the projectile on explosion with pressures of up to 900 kilos cm2, it has a lead base to which 2% antimony is added. Its extraordinary scope is due to the projectile...

AI Technical Summary

Benefits of technology

[0016] To be more precise, the projectile of the present invention has a single body, which is cylindrical in shape, with a totally hollow rear part to lighten the weight and a front part where the corresponding rod is located axially, terminating in the projectile's hard front tip. The tip is conical in shape but for its external base in the shape of a spherical cap which allows the hard point of the projectile's rod to fit perfectly in the mouth of the air chamber, while the rest of the rod is fitted into the rear part of the body under pressure in order to be bonded to it perfectly.

[0018] The hollow rear part of the body, as well as lightening its weight, allows the trajectory to be equilibrated in flight, thus avoiding pitching or deviations on account of the front part's being much heavier than its rear part or tail.

[0019] The nature or material of the body of the projectile is by preference lead, with high antimony content, thus avoiding possible deformation within the firearm's barrel, even when the pressure to which it is subjected is the maximum, approximately 900 Kg / cm2, so that, since it suffers no deformation within the barrel, its precision increases as its grooves will remain intact.

[0020] At the same time, the subcalibrated projectile of the invention offers the great advantage of causing absolutely no damage to the firearm's necking, since its diameter is two millimeters less than that of the barrel of the firearm or shotgun which fires it.

[0021] The aforementioned projectile also offers the advantage that when the tip, in the form of a cap, impacts against the animal, it sinks back and enters the air chamber, which is found in the rear part of the projectile's body where it is transformed into pellets and provokes a shock wave within the animal.

[0025] In another alternative embodiment, the container's tabs are endowed with some arching projections, instead of with locking claws on its inside face, from which and as far as the free end of the tabs come into being sloping sections or surfaces which, on exposure to the pressurized air, assist in the opening of the tabs in order to set the projectile free, thus making its exit or departure from the container easier.

Problems solved by technology

The projectiles used in hunting shotguns usually have a smooth external surface which gives rise to a lack of stability upon being fired and a modest range.
