Surgical gloves and throw them away later. Don’t want to do that? Then load your own and make your own bullets, lead and molds are common. In a country where owning a gun is against the law but still relatively easy to obtain why do they think someone couldn’t get ammo that was free of this stuff one way or another? This will catch zero criminals in my opinion and is just another idiotic sop to the gun grabbers.
But what if you prefer depleted uranium as a bullet material?
