Abstract
Abstract A shooting range that has a target chamber position at the target end. A camera on the chamber transmits an image of the target to the shooting end where it is displayed on a screen of a video micrometer. The video micrometer has cross hair reticles that measure a shot pattern generated on the target. The video micrometer has a tape recorder for recording the transmitted image, a printer for printing a hard copy of the pattern, a keyboard for data input, and is connectable to a computer for input of the shot pattern data.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
141 words
A target range having a target end and a shooting end, the target end spaced from the shooting end, a target located at the target end at which ammunition is fired to develop a shot pattern that is to be checked, and the improvement that comprises; a camera focused on the target area, target positioning means for positioning a sequence of replacement targets at the target area through which ammunition is fired and on which a shot pattern of the point of impingement can be visually observed, a visual display means at the shooting end connected to the camera for receiving and displaying an image of a target at the target positioning means, and measuring means contained in said visual display means for measuring the dimensions of the shot pattern developed on the target as displayed on the visual display means.
Claim 2
Dependent Claim
141 words
A target range having a target end and a shooting end, the target end spaced from the shooting end, a target located at the target end at which ammunition is fired to develop a shot pattern that is to be checked, and the improvement that comprises; a camera focused on the target area, target positioning means for positioning a sequence of replacement targets at the target area through which ammunition is fired and on which a shot pattern of the point of impingement can be visually observed, a visual display means at the shooting end connected to the camera for receiving and displaying an image of a target at the target positioning means, and measuring means contained in said visual display means for measuring the dimensions of the shot pattern developed on the target as displayed on the visual display means.
