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.

1 . A discarding sabot comprising: 
 a cylindrical shaped member for insertion into a cartridge casing for a .22 caliber weapon;    said member having an internal axial bore to hold a projectile smaller than .22 caliber.    
   
   
       2 . The discarding sabot of  claim 1  wherein the weapon is a semi-automatic .22 caliber handgun chambered for .22 Winchester rim-fire magnum or .22 long rifle ammunition.  
   
   
       3 . The discarding sabot of  claim 1  wherein the weapon is a .22 caliber rifle chambered for .22 Winchester rim-fire magnum or .22 long rifle ammunition.  
   
   
       4 . The discarding sabot of  claim 1  wherein the projectile is .17 caliber.  
   
   
       5 . An improved shell, projectile and sabot for converting a .22 caliber weapon for use with a smaller caliber projectile comprising: 
 a rim fired .22 caliber shell casing holding a quantity of propellant;    a discarding sabot inserted into casing and above the propellant, the discarding sabot being cylindrical in shape;    said discarding sabot having internal axially extending cavity for holding a smaller caliber projectile; and    a projectile of less than .22 caliber affixed in the cavity of the sabot.    
   
   
       6 . The improved shell, projectile and discarding sabot for converting a .22 caliber weapon for use with a smaller caliber projectile of  claim 5  wherein the caliber of the projectile is .17 caliber.  
   
   
       7 . An improved shell, projectile and discarding sabot for converting a .22 caliber weapon for use with a smaller caliber projectile in a rifle or semi-automatic handgun comprising: 
 a rim fire shell .22 caliber casing holding a quantity of propellant;    a discarding sabot inserted into 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; and    a projectile of .17 caliber affixed within the cavity of the discarding sabot.
