You want some common-sense gun control? Here you go.

157. Registration, OK

Ballistic fingerprinting, nope - not because of any theoretical objections, I'll gladly own every bullet that comes out of every one of my weapons, but because it's more or less completely useless.

Since I bought them, every one of my rifles has been "fire lapped" by shooting abrasive-coated bullets through it. It's done to recondition a potentially abused barrel and to increase accuracy. It also completely changes the patterns the rifle leaves on the bullet - unless you'd mandate a resubmission yearly, there's no useful information to be gained from "printing". The same effect happens with any high-volume shooting, I'm just using the lapping as a particularly rapid and clear example. New York dropped their law after umpteen years and bumpteen million dollars did exactly nothing.
