  • Patent number: 5291832
    Abstract: A dummy round for use in firearms training. The dummy round can be loaded in a conventional semi-automatic or fully automatic weapon. The dummy round is configured in the same manner as a standard round of live ammunition. This allows the dummy round to be loaded in a clip, chambered and ejected in a normal manner. The casing portion and the bullet portion of the dummy round are constructed of a single integral unit in order to eliminate the risk of separation of the dummy bullet from the casing during ejection of casing from the chamber.
