Shotgun choke with integral wad-stopping feature

Abstract

Disclosed herein is a shotgun choke with integral wad-stopping feature for use with an existing shotgun. The choke generally comprises a hollow cylinder having (an) a coupling for securing it to the muzzle end such as an external series of screw threads proximate one end for screw-insertion to the muzzle end of an existing shotgun, and an internal channel defined by an overall taper running from the inserted end to the output end to constrict shotgun pellets passing there through. The wad-stopping feature is accomplished with a series of raised internal projections or steps (raised from the internal walls of the channel), the projections being spaced throughout the tapered channel to retard and separate a traveling wad from the shot when passing there through.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application derives priority from U.S. Provisional Patent Application Ser. No. 60 / 454,368 filed Mar. 12, 2003BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to shotgun chokes and, more particularly, to a choke (barrel) reducer which constrains the shot pattern of pellets fired by a shotgun, and which additionally slows the wad down so that it will not follow behind the shot. [0004] 2. Description of the Background [0005] It is well-known that choke devices can be used to tighten the shot pattern of pellets fired by a shotgun. A choke is a removable interior tube at the end of the shotgun barrel that constricts shot dispersion. Choke tubes typically come in various configurations and can produce either a very wide shot dispersion, or a much tighter shot pattern. Different chokes are used for skeet, trap, and sporting clays, and hunting. [0006] Typically, shotguns are now provided wit...

AI Technical Summary

Benefits of technology

[0009] It is, therefore, the primary object of the present invention to provide an improved choke design for a shotgun choke with integral wad-stopping feature operative on fabric or cardboard wadding, plastic shot cups, or otherwise.

[0010] It is another object to provide a choke that can be screw-attached to the muzzle end of a shotgun, the choke having an integral wad stopper to stop the wad as it moves outward from the barrel, thereby rapidly separating it from the pellets and minimizing its effect on the shot pattern.

[0012] The present invention's design is simple and straightforward, highly effective, can be economically manufactured, and there is no wasted material in the production process.

Problems solved by technology

There are no existing choke designs that inherently prevent this.

However, the projections are only operative on a plastic wad cup which carries the pellets, and such wad cups are typically used only in a portion of modern shotgun shells.
