That would make that system unworkable, but what about making the powder/projectile identifiable for each box, and the ammo gets registered. I know this wouldn't go over well with gun owners and the NRA, but is a life worth the trouble and expense? How about a hundred lives?
Powder theoretically all gets burned up. So you would be looking at residue. but that would be unreliable. If i go to the range I will usually fire 100 rounds in my pistols. That would mean i could potentially have 100 "nano" markers carbonfied (made up word

) in the gun. Then what if I do shoot someone and they are 50 feet away. They shouldnt have any gun powder residue hit them so if i pick up the casing there (theoretically again) shouldnt be any residue at the scene of the crime. Its kind of like microstamping where it seems like a good idea but it would be complex and unreliable IMO.
ID'ing the casing won't help. What about imbedding something in the bullet
Your are talking billions of bullets in completed ammo and probably millions more in component for for reloaders. Then you have those who cast their own. So again it would be difficult to implement. Plus upon impact a bullet can break into tons of pieces or it could penetrate and never be found. you would be relying on the bullet part that is stamped to stay intact to be able to read it.
More ideas would be great in this thread. Thanks for not implying that I'm an idiot for posting this.
Im always open for debate. Its always interesting to me seeing the different views on subjects. Its just once one person goes personal attacks that i just stop caring. Ive debated with plenty of anti-gun guys and had some great debates. but ive also had guys just go personal and i just roll my eyes and walk away.
As for the cost....you could say that about a lot of things. Baseball bats have killed more people than rifles in this country. yet i can go to big 5 and buy one for... (hell i dont even know 50 bucks?). Thats one of the issues gun owners have. People are trying to make things so difficult for the law abiding owners just cause the media waves the bloody shirt at every single shooting anymore. Yet you never hear about the baseball bat murders for more than a night (if at all).
Would this really stop actions of the mass murders anyways. Most of them bought their guns legally, bought their ammo legally, then did illegal things. My opinion is they would have just as gladly bought the marked ammo (by whatever method) and used it since none of them expect to live (expecting to live is my opinion). Same would apply for a lot of the murders committed using handguns. The ones who buy legally then use them for illegal purposes arent thinking about getting away with it. The gangbangers...well they dont buy legally anyways and i doubt they care what ammo they use either
