- Title
FIREARMS EVIDENCE--REPLICAS OF FIRED BULLETS.
- Authors
Davis, John E.
- Abstract
This article discusses the reproduction of firearms evidence, with particular reference to fired bullets. Replicas of fired bullets could serve a number of valuable functions. Replicas could provide a permanent three-dimensional record of specimens involved in serious crimes, serving to lessen the problems which would attend any loss or damage to the original specimen. They might be of value in cases involving recovered weapons. Furthermore, unnecessary test-firings of the weapon might be avoided by providing replicas of the first few tests for all preliminary comparisons. Replicas might be used merely for the Specimen File to indicate the characteristics of various arms. A problem associated with the production of replicas, whether they be tool marks or bullets, is to obtain a final product which has light-reflecting qualities like that of the original. There are various possibilities for casting media, this includes plaster of Paris, a fusible alloy, silicone rubber and wax compositions. Initial tests should be made using an undamaged bullet. Prior to pouring molten wax into the mold, it is essential to coat the hollow of the mold with fine aluminum powder. Once the mold has been made and prepared, pouring of the wax may begin.
