  • Patent number: 4132000
    Abstract: An apparatus for the generation of rifle targets for load development and accuracy testing of scope assisted rifles is disclosed in which the rifle targets have sighting areas optimized for a particular scope. The apparatus comprises a base having a first axis and a second axis orthogonal to the first axis, a plurality of apertures in the base for forming the sighting areas on the target, pilot means within the base for successively positioning the apertures to form the sighting areas and lines of space control disposed about the pilot means for optimizing the dimensions of the sighting areas. The present invention is utilized to generate rifle targets having sighting areas with dimensions optimized to the power of the scope and the width of the cross hairs. An embodiment of the present invention is capable of generating targets having sighting areas with dimensions optimized by the size of the dot reticle of the scope.
