125,671. Hoyle, J. R., and Strang, H. B. July 3, 1917. Projectiles.-Relates to capped armour - piercing projectiles, and consiets in a construction which prevents the nose of the projectile from easily forcing its way through the cap when impact occurs, and thus causes the cap to give a heavier blow. According to the invention, two or more annular grooves or ridges B or a series of separate but annulary-disposed projections or recesses of substantial dimensions are formed along the ogival head of the projectile, while the cap D is shaped internally so as to fit closely on the whole head of the projectile without deformation, and engage the projections or recesses. The cap may have a hardened central or annular protrusion such as G, and is preferably covered by a hollow nose H.
