Havent posted here in quite awhile and had to reset. Several years back (Maybe 2) I came across polycase ammunition.The company used technology that I seem to recall was begun in Spain, that used a polymer and powdered copper for the projectile/bullets. Ultimate goal was to make a non reloadable lethal round for military use so that enemy combatants (Can I say Terrorists here?) could not reuse the fired cases nor reclaim spent projectiles. Loads were made in 380/9mmk, 9x19, 45 acp, 38 special and 357 magnum. Initial cases loaded by polycase were brass boxer primed and made starline and other commercial brass. Ive not sem any with polycase markings. Not much later, Ruger firearms contracted for ammo with their name on the cases. (I have these in 9x19 and 45 acp and I think 380). Headsatmp are Ruger and caliber Nickel plated cases.
Most recently another company has introduced NovX ammo with the ARX, RN Training and supposedly Tracer loads. (9x19 only so far. Projectiles come from one source (Polycase?) and cases from another. Cases are two piece Nickel plated 7078 aliminum base married to a Nickel Stainless case. 50% lighter than brass and a lot stronger (Rated to 65,000 psi) While I havent yet acquired any NovX for col;lection, Im going to soon. For more info the most recnet Shooting Times magazine has a decent article on NovX 9x19. btw comes in std and +P loads.
