Polymer ammo: still a bad idea

[Balog]

Now we just need some plastic .50bmg to shoot through a Hesse...

[cordex]

Yikes.  I still have some polymer cased Natec .223 around somewhere from about ten years ago.  For the couple-hundred rounds I tested it was mostly okay, except for a case neck separation.  Nothing destructive in that failure, but bits of the neck left in the chamber did cause failures to feed - so not exactly a good thing.

[Regolith]

Well, if anyone has stock in whatever company makes this stuff, now would be a good time to divest. 

[Azrael256]

Uh-huh.  Bad Idea(tm).

Would somebody scroll down to the bottom and tell me if I seriously saw an ad for tacticool q-tips?

[Jim147]

Why was he firing purchased ammo from under the table? Seemed like he knew it was going to do something. Hard to have insurance and be in business if every round you sell blows up. A follow up  from both sides would be good.

The worst I have seen from that type of ammo is part of the case left in the chamber on extraction. I won't buy any now because brass and steel are cheaper but what do I do when the prices flip flop and I'm out of reloadable brass? I guess I reform the '06 stuff and dig out the boxer primed steel.

Uh-huh.  Bad Idea(tm).

Called ram rods.

Germans used to shoot plastic cased plastic bullets in training.

This stuff, we'd find their cases all over the ranges

I wouldn't call them tacticool, they're a cleaning item.

I use regular q-tips to clean my guns all the time.  They're useful for getting into nooks and crannies.

yikes!   it does seem as though he was anticipating trouble......

(scratch that million dollar idea....)

Weren't Trounds made of plastic?

[lee n. field]

trounds

standard metal round inside a shaped plastic sheath, is how I interpret pictures I've seen.

[280plus]

That guy is lucky he didn't get hurt, severely. He should have used a ransom rest, cord tied to the triggers and fired from behind a blast shield. Like they do on Myth Busters.

Both.

The tround, with a metal head to accept the primer, could be the cartridge case, or it could be an adapter.

Not sure if the same tround could do both or not (punch the metal head out of the cartridge tround)....

Right, but you're not an idiot.  Walgreens sells name brand stuff for... $3.39/500.  These guys want $8.76 for 200.

You're obviously doing it wrong because drugstore qtips aren't precision wound to the exact diameter of the bore.  People who use off-the-shelf qtips are tutu-wearing girls who prefer 9mm over .45.  Expect a wheelbarrow load of debarked Chihuahuas to show up when you least expect it!

[280plus]

I like to take a nylon wire tie, cut the end off at a sharp angle and use it to get into those pesky crevices and dig the dirt out. Guess I should market this idea.

Ahh, I missed the price.  I just took the "precision wound" part as indication that they could accommodate different bore diameters.

The walgreens q-tips aren't Milspec, they are inferior and will leave your rifle jammed when your life depends on it.

Do they make this ammo in .40? Seems like it would go good with a glock.

Uh.... actually... I know him quite a bit better than you do.....

He was testing plastic cased ammo.  I would have done the same thing, if I was ever to willingly do something so dumb.

That's brilliant

In retrospect it looks obvious, but as I said earlier, I shot a bit (over 200 rounds, I believe) of commercially loaded plastic cased ammunition a decade ago with no catastrophic failures and only one non-catastrophic failure.  I certainly never considered hunkering down behind a table when shooting, nor setting up a remote rig to fire the gun.

You can do the same thing for free with a popsicle stick and a pocket knife.

[T.O.M.]

I think I recall someone making a practice round for .38/.357 revolvers that used a plastic case.  Think you just used a magnum primer for power, and range was limited to "across the room" distances.  Obviously, the pressure levels were a lot lower than full-house .308 rounds. 

[MillCreek]

^^^ Speer used to sell these.  A plastic case, a plastic bullet and powered by the primer.

[mtnbkr]

They still do.  I've seen them in stores.

I have a bunch.

They go through drywall quite nicely.
