I have gotten some 556 NATO ammo with polymer casings and tested at the range (was Military surplus - USA - Made) my point on that is it can not be reloaded , and my testing found that was not as good as my reloads, plus it gave large groups, and after 50 rounds left my rifle with lots carbon.... and the price was more than standard ammo.... the French Military use a 9mm and 7.5 Polymer case as blanks for training...You get what you pay for.... I do not rate the polymer case as ready for combat or survival use......2 star ammo......
