Abstract
1303797 Projectiles; firearms COLT INDUSTRIES OPERATING CORP 8 Dec 1970 58311/70 Headings F3A and F3C A projectile for squeezebore firearms comprises a plurality of nested sub-projectiles 62, Fig. 7, which on passing through the squeezebore of the firearm are reduced in diameter and separate from one another. A lubricant is provided between the inter-engaging surfaces of the sub-projectiles. A frangible plastics sleeve 61, with an optional portion 79, holds the sub-projectiles together. The mouth of a cartridge case (not shown) is crimped into a groove 63 of the plastics sleeve. The rear subprojectile can be of modified form and comprises a body 67 formed with a recess 70 for a tracer composition, and a skirt 68, which in use, acts as a propellant gas seal. The rear subprojectile may be armour-piercing. In another embodiment (Fig. 8, not shown) the subprojectiles are held together by a layer of wax or oil between adjacent sub-projectiles. In a further embodiment (Fig. 3, not shown) a plastics sleeve (32) holding the sub-projectiles together extends into longitudinal grooves (30) formed in the surface of the sub-projectiles so as to impart spin to the sub-projectiles when the projectile is fired from a rifled barrel. The squeezebore firearm can be a machine gun 10, Fig. 1, with a squeezebore barrel 12 secured to the barrel 11 by a nut 13.
