Polymer Cased Ammo, Is This The Future?

Guess I might be hard headed, to stubborn to trust plastic but some how I think poly cased ammo might be a bit overboard. Possibly for low cost rimfire but I just can't see it for centerfire ammo.

I found this while surfing the net searching for a holster. Poly cased 380 ammo. The video shows and article claims it is reliable. It is on the internet it has to be true!!

You have a sharp eye Doc. I went an took another look and other pictures show the split in other cartridges. Almost appears to have been deliberately manufactured with the split. Either way until it is proven I wont use it based on a single net article. Notice two on the right or pink cartridge on top of mag.

My guess and it is just speculation. The bullets are probably seated using some kind of adhesive to keep them in place. Just can't believe the split plastic provides enough neck tension.

 

The poly cartridges are reminiscent of the all plastic shotshells of the late 70's. I only saw them for two years here in Phx. Second year they added a metal ring to the rim and added label saying something about not being recommended for auto loaders. Been way to many years to recall the price but the all plastic shell cost considerably less than conventional metal-plastic shoitshells.

 

At the time myself and as many as a dozen or so co-workers went dove hunting together after work. Single shot and double barrel shotguns didn't seem to have any problems with the plastic rimmed shells. I shot up a few boxes using my Stevens 311 side-by. I don't recall any extraction problems but felt they were kind of gutless. Those using pumps and autos with the all plastic were constantly poking them out with a cleaning rod.

It was a disaster with the .223 ammo in the mid-2000's. Case head separations, buckled cases, actually seen some that had started deform from heat. It was around long enough for us RSO's to caution shooters not to use it in AR's , total crap. And they had some that was tracer in a red case, which was a big No No at the Range.

I can be a bit open minded trying it in handguns but never for use as self defense ammo and no way at rifle pressures. I don't know the numbers but a ball park guestimate is 223 combusts about 20-30,000 more PSI than 380. Not until imaginary plastic like that used in one of my favorite flicks, The Day The Earth Stood Still become a reality.
