I used their Contact Us e-mail link to send whoever's responsible for this a rather nasty e-mail. Not so nasty I wouldn't feel it proper to quote it here, but nasty enough.
Just remember, smart guns are for stupid people, we defeated it. Propellant taggants perform poorly, we defeated it. Microstamping is for hardened metals that won't get deformed, not for lead that'll get mutilated. We'll defeat this once and for all eventually too.
Their goal is really not to make it easier to trace crime guns, or in this case, crime slugs, but rather to attack us where we're vulnerable, our ammunition supply. This bill is to strangle the ammunition supply in any state that adopts it. Doubtlessly, they would exempt military and law enforcement from the requirement of having to buy the unobtainable ammunition no one's manufacturing. But I never mentioned that exemption idea to them.
Keep realoading!
