I may not be up to date on the latest technology, but I can't see a polymer that would hold up to those pressures and temperatures.

this pdf www.dtic.mil/ndia/2002infantry/husseini.pdf 3.86megs also a couple of hits that mention this possibly in use with the XM8. being developed by a company called NATEC formerly AMTECH. got more hits searching for AMTECH polymer cased ammuntion than i did natec. still looking though, pretty interesting. |

well if nobody was around is it still considered out in public? [:D]
anyway, its claimed that this stuff keeps the chamber cooler and gives same velocity with less powder. i would like to now just how much cheaper it is. i could go for $100 a case M855 oh well its not like us civies will ever get any of this. evil plastic ammo gets past metal detectors or some such crap.. |

I didn't check the pdf you found but,FWIW, I picked up a dummy round of polymer cased ammo at a law enforcement trade show back in 1991. Headstamp is AMTECH at the 12 and 223 at the 6 position. The bottom 3/8" of the case is brass and the rest is white polymer. Manufacturer's rep. at that time said it was coming out soon.

I'm betting that it is not reloadable.

During AMTECH's brief commercial run of polymer cased .38 Special ammo, their reps handed out polymer cased dummies of 5.56x45mm, 7.62x51mm, and 12.7x99mm (.50 BMG). |

I remember they ran ad's in the magazines at the time. I'm wondering what the holdup has been. |
