Not exactly what you want ,but I did use a laser dot mounted to a scope for this a few years ago. The "Beam shot" laser would project a dot on the target. I used a night vision device to see the dot and aim it at the coyotes. I used a 7br barrel for it's flat shooting and accuracy. The "dot" would show up as a bright white spot and was sighted to the guns point of impact at 200 yards. It would be within 1 1/2 inch of bullet impact at any range out to about 200 yards. I could have the gun out to the side at arms length and STILL hit a coyote.
