Rotating Band Study. Test of 3-in./70 AA Projectiles with Armco Iron Rotating Bands

Abstract

3-in./70 projectiles of various types, fitted with gilding metal rotating bands, have been observed to exhibit serious band wear; that is, partial or complete obliteration of the engraving of the bands recovered after firing. It was desired to investigate the effect of replacing the gilding metal with soft iron, in order to determine the results of using a material with a considerably increased melting point, and if this change would produce a band which did not fail, to determine the effect upon gun performance.
