Reassertion of Composition A-3 in Projectiles

This report presents the results of a study to evaluate postpressing growth or dimensional changes observed in fuze cavities of Composition A-3 loaded 5 in. projectiles. Because of the introduction of improved press loading procedures during 1970, postpressing growth, or reassertion as it is generally called, is no longer a problem and the waiting time currently imposed between pressing and drilling the fuze cavity should be eliminated.
