Benefits of technology

"The present invention relates to a discarding sabot for a .22 caliber weapon that can be used with a smaller caliber projectile. The sabot is a cylindrical shaped member that is inserted into the weapon's casing and holds a smaller projectile. The invention also includes an improved shell, projectile, and sabot for converting a .22 caliber weapon for use with a smaller caliber projectile in a rifle or semi-automatic handgun. The technical effects of the invention include improved accuracy and reliability in using smaller caliber projectiles with a .22 caliber weapon."

Problems solved by technology

While there have been a large number of sabots developed, none have been developed, heretofore, for use with a .22 caliber long rifle or a .22 Winchester rim-fire magnum round.

Embodiment Construction

[0023] The present invention is specifically described with reference to the enclosed Figures wherein the same numbers are utilized. In general, the present invention is directed to a sabot system for converting .22 caliber rim-fire ammunition for use with a smaller .17 caliber projectile. A .17 caliber projectile is about one-half the weight of a .22 caliber projectile and has an effective range of two hundred yards.

[0024] Specifically, the invention, in a most preferred embodiment, converts a standard .22 Winchester Magnum Rim-Fire (.22 Magnum) and .22 caliber long rifle round from firing a .224 inch diameter projectile to a round capable of firing a 17 caliber projectile. To accomplish this a .224 outside diameter discarding sabot containing a .17 caliber projectile will be inserted into a standard .22 magnum rim-fire and .22 caliber long rifle case containing propellant.

[0025] Referring to FIGS. 1 through 3, the invention comprises a .22 caliber case 10, and preferably a rim f...

Abstract

An improved shell, projectile and discarding sabot for converting a .22 caliber weapon for use with a smaller caliber projectile comprising: a rim-fire .22 caliber shell casing holding a quantity of propellant; a discarding sabot inserted into the casing and above the propellant, the discarding sabot being cylindrical in shape; said discarding sabot having internal axially extending cavity for holding a .17 caliber projectile affixed in the cavity of the sabot.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims benefit to provisional application 60 / 608,171, filed on Sep. 7, 2004, entitled “Sabot Allowing .17-Caliber Projectile Use in a .22-Caliber Weapon,” which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION [0002] The present invention is directed to the field of modifying .22 caliber rim-fire ammunition (.22 long rifle and .22 rim-fire [.22 Winchester rim-fire magnum]) to fire .17 caliber projectiles with the use of a .22 caliber discarding sabot. BACKGROUND OF THE INVENTION [0003] Discarding sabots have long been utilized in weaponry. Simply put, sabots are inserts which enable a gun machined for a particular caliber type of cartridge to accept and fire a smaller caliber projectile. There have been a number of patent directed to the use of discarding sabots for the conversion of projectiles of one caliber so that they may be used in rifles of another caliber. U.S. Pat. No. 4,590,862 disclo...
