Hello, this is more of a thought experiment, if ammunition had an additive that would cause it not too fire when some type of external field is applied or external trigger you can more or less make a dampening field for a gun with this ammunition, would not fire. Just throwing it out there. We can't take all the guns that's never gonna work, so we need to come up with other ways to stop all these mass shootings. You can hope for world peace and kumbaya but that is not going to do it. My2Cents - spend it any way you want
