I just typed up a lengthy comment on the above link and somehow lost it before posting. Now I'm annoyed enough that I don't feel like retyping the whole thing. Anyway, here is the latest in the lengthy evolution of polymer cased ammo. The comments on thefirearmblog are interesting as most don't predict a savings for the consumer. With no cost savings I see little reason to purchase this stuff. I do like the concept of being able to visually inspect the powder level of a loaded round by way of the semi-transparent casing.

I think we need to start a "Solutions For Problems That Don't Exist" thread.

That's not a bad idea. However, the most expensive component is the brass case so it's pretty easy to assume the average shooter wouldn't mind seeing the cost of ammunition drop. Before that can happen the manufacturers would have to retool the plants which is unlikely.

My first questions are:

Will the polymer withstand UV radiation/degradation?
Will the polymer plasticize in air?
Will the polymer off-gas and potentially poison the powder?
How will the polymer withstand long-term storage in both bulk crates and loaded mags?

1/4 of the case is still brass.
Is there a weak point where the two are joined?

I don't really "follow" ammunition, but I know polymer ammo is nothing new.
I have a few rounds of 223 around here with a tan, polymer case. I can't recall the brand.
A member had picked up a case of it for his AR15 but had nothing but problems with it.

The BIG difference is on the overall weight of the cartridge.

IMO:

Unless you're humping a standard load-out on the 2-way range - so what? Is that worth the potential performance (failure?) issues?

Cool. It's like a pointy shotgun shell...

Ive had these for years.

My question, will this stuff melt or cook off in a hot chamber? Brass can cook off,so I would think that the melting point of plastic should be a concern.
