The weight of my ammo is not a factor when hunting. I don't carry that much. Who does?

my big question is, TIME, how long is the shelf life on these gunna be? I live in the pheonix metro area so its pretty hot here sometimes, in 6-9 years of these sitting on my shelf are they gunna fall APART is the glue going to become tacky and alow that bullet to move, I dont see a problem of shooting them within the year that they were bought but like i said what about the long term?

I think I'll wait till casings become edible after firing. Now that would be something to chew on!

I don't know how much ammo y'all carry when you go hunting, but 20 rounds of center fire is a gracious plenty. If I am duck or dove hunting, I generally will take a couple boxes of shells, but I don't need a wheel barrow to transport them to the blind or side of the field. And they have been paper or plastic since 'forever.'

I can't see a couple ounces per box making a He** of a lot of difference. Now, if it is a couple dollars cheaper, that might be good. I don't hunt enough, or shoot varmints enough anymore to reload my .270 like I used to. Old age adds limitations, unfortunately. TB

good point pbshooter, they would also reduce metal it takes to make casings.

Probably ought not be too shy about jumping on the band wagon. I remember when everyone was poo poo-ing the "plastic guns". What manufacturer isn't producing them now?

@Savageshot: "Polymer" is a general chemical term for materials made up of repeating, linked, molecules, so not exclusively refering to petroleum based products.

I would suppose that all synthetic polymers made today are petroleum based but in the grand scheme of the world of plastics that we live in -- I expect that other than the reloading issue these cases are far cheaper than brass.

When you travel over seas to hunt, you are only allowed 11 kilograms per rifle. That equates to about 2 boxes of 458 win mag ammo. On a 21 day Safari, that is not much ammo.

Way too expensive for me. I'm a P.D. shooter and I reload only. Other than rimfire I havn't bought a factory round in decades. If it's not reloadable it will die on the vine. I can see this stuff all over the range

ages ago a friend of mine bought a couple boxes of 12ga that were molded plastic or polymer. the primer was set directly into the plastic case--the only metal on the thing, and if memory serves there was a paper type patch to seal the front--much like those used in the old paper shells. the things shot great but were on the market only that one year that I can remember. guess there wasn't a big too doo made of them so they didn't make any more. not real sure but I believe there wasn't much choice in shot sizes either. personally I would be afraid of reloads in these things since they are put together with glue instead of crimp. if fire will cut the rifle (note the 264 win) it will have to do the same with the polymer thereby rendering it useless for reloading. personally I carry about 20 rds while hunting unless duck or dove hunting so no weight saving there. also, these will be in comparable price to standard match grade ammo??? that stuff is usually pretty expensive!!

Not the first time this has been tried. 20 years ago or so. Even had reloadable plastic cases and strange bullets that went with it. Gun store here in town still unloading the bullets with funny narrow base that fit into plastic case. Maybe round #2 will be better accepted...

Plastic casings would be ideal for military use but for the majority of hunters/reloaders/shooters they appear to not be feasible. Seems to be another item made of oil (the material of all polymers) that needs to remain metal, as many products need to revert so as not add to material from oil producing countries.

I'm not a fan of a non biodegradable casing, I already see enough discarded casings in the field, but at least the metal ones will totally biodegrade.

Metal can be recycled just as well as plastic so that isn't an issue.

Steel cases are the most degradable I know of, and are cheaper than brass.

If it is reloadable at all I doubt it will stand up to as many reloadings as brass but I could be wrong.

Other than weight I see no real advantage over brass, and that would be minimal as most of the weight in a round of ammo is the lead in the bullet.

And as to hunting ammo I usually carry 40-50 rounds each for my rifle and handgun, or shotgun and handgun, depending on season.

If these are made from a petroleum by product then you can bet your bottom dollar the cost will be outrageous.That is exactly what our government is trying to do today is put a stop to the average person from being able to buy ammo. I don't want any part of it.It's best to go ahead and stock up on the good ammo that is in brass casings.Brass will last a life time. we will be needing it with the way things are going now.

Remember;
Shotgun shells used to be brass also.
Now they are plastic (?) and easly reloaded.
Lets wait and see what we get and then we can buy it, or leave it.

Let me know if im wrong but isn't polymer and petromlium product? if i am right, with the amount that most people shoot myself included, the gas of gas and ammo would go up i dont want eithier one.

I can see those not being able to reload. Although there light weight they're probably easy to break to. I wonder how they stand up to the heat of firing.

let's bring back David Dardick's "tround"

the bad part about this is that the military expends large amounts of brass that is then put onto the market for reloaders. if they do away with brass for this stuff that is really going to crimp the style of reloaders because the stuff just won't be available. I would imagine shelf life of this stuff would be comparable to brass ammo. I have some that was produced in 66 and has been kept cool and dry in the house and shoots like the day it was made.

i want to see it field tested
