A new US company, Polycase Ammunition, is entering the commercial ammunition business in the US with a line of plastic case pistol ammunition. Their first entry into the commercial market is 380 Auto in a number of loads that should reach distributors before Christmas. The development cases, and the initial 380 cases are made in Spain, but production will soon be established in the US. So far I have only seen the development cases which have a black polymer-plastic body and steel head. Other calibers will also be produced.
I am putting together an article on this ammo for the next IAA Journal as I learn more.
