Abstract
574,579. Projectiles. STEVENS, A. H. (Western Cartridge Co.). June 23, 1943, No. 10141. [Class 9 (i)] Projectiles of expanding type for use with high-power rifles comprises a core of soft metal, a thin hard metal tip jacket covering the forward end of the core and a thicker hard metal base jacket which extends along a major part of the core and overlaps the tip jacket whilst leaving a large part of the tip jacket exposed. The core 6, Fig. 1, may be of lead or lead alloy, tapered at the forward end to receive a tip jacket 7 of drawn copper or copper alloy &c. The tip jacket may extend to within a calibre of the base of the projectile or alternatively may extend to the base or completely encase the core. The base jacket 8 also of copper or copper alloy &c. covers the base and extends forwardly to overlap the tip jacket, the base jacket being chamfered at 13. One or more circumferential grooves 11, 12 or other indentations may be provided to retain a lubricant or to receive a cartridge case secured to the projectile by crimping &e. The formation of the grooves 11, 12 may also serve to interlock the base jacket with the tip jacket and core. The base and tip jackets may be secured together by welding. The base jacket is thicker than the tip jacket, these jackets being respectively greater and less than .02 inch thick.
