DIMENSIONAL CHANGES IN SHOT GUN BARRELS CAUSED BY THE FIRING OF HARD METAL PELLETS

Abstract

The report describes progress to date on the development of a means of assessing the wear and deformation of shot gun barrels caused by the firing of non-toxin but relatively hard metal pellets. The results of an initial series of tests on hard metal pellets, some of which were coated with non- metallic anti-wear coatings, are also presented. These indicate that the enlargement of the bore of the barrel at the muzzle constriction (choke) was, in this ease, primarily due to the 'hammering out' action of the hard pellets, with the wear of the bore being a secondary effect. The pellet coatings tested proved to be ineffective as a means of prevent(Author)
