Abstract: Method of fabricating a dummy practice ammunition round to dynamically match behavior of an existing live ammunition round during manually cycling of the action, or other demonstration. A dummy practice ammunition round of identical contour is formed, having a center of gravity (mass) in the same position as on the existing live ammunition round. Weight is matched by removing or omitting material through coring into the case head of the round or by hollowing it out.
