Before I jump on the PC bandwagon I need these questions resolved by an authoritative source. I have other concerns as well but these are the two biggies.

Actually, shotgunners have already did the legwork along with gunpowder mfg's.
There's 2 types of coating.
polyurethane
polyester
The polyurethane is a paint product and involves chemicals to use.
The polyester is a powder product that uses static (#5 container air soft bb's). to use.
Shotgun shell cases are made out of a polyurethane.
Shotgun wads have been made out of polyurethane, nylon, polyester.
Polyester adipate (adipate ='s alkyd resin) has been used to coat gunpowders for a long time. It slows the burn rate of the powder.
So anyway, everyone's been shooting these types of plastics for decades with no ill affect on anything.
I use the polyester coating and love how easy it is to clean the firearms after a range session. What a revolver looks like after a typical 200round range session. Hoppe's #9 on a rag and everything wipes right off. Use the same #9 on a patch and after 2 or 3 passes down the bore, it's clean. No more brushing, etc, just 1 wet patch and 1 dry patch. The cylinder needs a standard cleaning due to the carbon build-up from the burnt powder. But the cylinders are no where near as bad as they would be with the burnt carbon/lube from traditional cast/lubed bullets.
Try doing that with traditional cast/lubed bullets.
