Gun sighting

Abstract

A gun sighting kit ( 8 ) and a method for gun sighting are preformed by placing a clear sheet ( 12 ) having a concentric circular graph ( 10 ) over a cluster of shots ( 32 ) on a target ( 28 ) that need only have a center location ( 30 ). A center ( 16 ) of the concentric circular graph has a hole ( 16 ′) through which a center ( 36 ) of the shot cluster is marked. The kit ( 8 ) also includes a square grid ( 18 ) on a clear sheet ( 20 ) that is then placed over the marked target so that a center ( 22 ) of the grid is located at the target center in order to permit determination of the horizontal and vertical deviation of the shot cluster center ( 36 ) from the target center, in order to permit necessary gun sight adjustment for proper aiming.

1 . A gun sighting kit comprising:
 a light transmitting sheet supported concentric circular graph having a center and being placed over a target which needs only a center target location at which a gun is aimed and fired for a plurality of rounds that establish a cluster of shots with a center determined by the center of the concentric circular graph; and   a light transmitting sheet supported square grid having a center which is placed over the center of the cluster of shots on the target to determine the horizontal and vertical deviation of the shot cluster center from the target center location and thereby determine any necessary adjustment of the gun sight for proper gun aiming.   
   
   
       2 . A gun sighting kit as in  claim 1  which includes separate light transmitting sheets respectively supporting the concentric circular graph and the square grid. 
   
   
       3 . A gun sighting kit as in  claim 1  wherein the concentric circular graph and the square grid are each supported on a clear light transmitting sheet. 
   
   
       4 . A gun sighting kit as in  claim 1  wherein the concentric circular graph has a hole through the light transmitting sheet to permit marking of the shot cluster center on the target. 
   
   
       5 . A gun sighting kit comprising:
 a first clear light transmitting sheet including a concentric circular graph having a center including a hole and being placed over a target which needs only a center target location at which a gun is aimed and fired for a plurality of rounds that establish a cluster of shots with a center determined by the center of the concentric circular graph which permits marking of the target through the hole; and   a second clear light transmitting sheet including a square grid having a center which is placed over the marked center of the cluster of shots on the target to determine the horizontal and vertical deviation of the marked shot cluster center from the target center location thereby determine any necessary adjustment of the gun sight for proper gun aiming.   
   
   
       6 . A method for sighting a gun comprising:
 firing a plurality of rounds at a target, which need only have a center target location, and thereby establishing a cluster of shots;   placing over the cluster of shots a light transmitting sheet supported concentric circular graph having a center and positioning the concentric circular graph with respect to the cluster of shots to establish a shot cluster center at the circular graph center; and   thereafter placing over the shot cluster on the target a light transmitting sheet supported square grid to determine the horizontal and vertical deviation of the shot cluster center from the center target location to thereby determine any necessary adjustment of the gun sight for proper aiming.   
   
   
       7 . A method for sighting a gun as in  claim 6  wherein the concentric circular graph and the square grid are on separate light transmitting sheets separately place over the target from each other. 
   
   
       8 . A method for sighting a gun as in  claim 6  wherein the concentric circular graph and the square grid are each supported on a clear light transmitting sheet. 
   
   
       9 . A method for sighting a gun as in  claim 6  wherein the concentric circular graph is supported on a light transmitting sheet having a hole through which the shot cluster center is marked on the target. 
   
   
       10 . A method for sighting a gun as in  claim 6  wherein any abnormal shots are ignored upon establishing the shot cluster center by the concentric circular graph.
