I claim the ornamental design for a rifle shooting support, as shown and described.
FIG. 1 is a perspective view, taken generally from above, of a preferred embodiment of the novel design for rifle shooting supports;
FIG. 2 is a top view of the preferred embodiment of FIG. 1;
FIG. 3 is a bottom view of said preferred embodiment;
FIG. 4 is a view of one side of said preferred embodiment; to FIG. 5 is a view of the other side of said preferred embodiment;
FIG. 6 is an elevation view of one end of said preferred embodiment;
FIG. 7 is an elevation view of the other end of said preferred embodiment; and,
FIG. 8 is a perspective view, taken generally from above and one end, of said preferred embodiment, wherein a rifle is shown in broken lines to illustrate the environment related to the claimed design and form no part of the claimed design.
Surface shading is used in the drawings to show contour in the design that otherwise might not be apparent in a particular figure.
