The additive in the wad cup is activated by light, oxygen, and heat. It would have a shelf life of 7-10 years before the degradation inside a shell case would begin.

One of the leading shotshell manufacturers in the area told me shotshells without the additive have approximately the same shelf life. If not used for several years they don't work properly.

I know that you are running for office but I fail to make the paranoid connection to the government having anything to do with this product being added to wad cups. Remember that the original plastic (Polyethylene)to make the wad cup comes from......OIL! If the government wants to control all aspects of our life, all they have to do is control access to oil and all of the products produced from it.

It ain't rocket science and they don't have to target specific products to make it happen. Just one broad paint brush swipe can bring the whole house of cards down. Pretty scary huh?

But that is just my humble opinion.
