The funny thing is, it's not as stupid as the tech copyright/patents that are currently happening. At this point, on the tech side, people are getting copyright on things like "a system of doing something by selecting something" (not as exaggerated as I'd like).

On the marked ammo, I don't think this will ever pass on a widespread scale. It may happen in a single state, but I doubt it. They would never be able to enforce it. There's absolutely no way it would pass here in the northwest (other than maybe Oregon, which I doubt, and California which doesn't count), and if it did the police would look the other way 99% of the time when they caught you. Even in the urban states it's a huge expense, and why would ammo manufacturers want to have to deal with all sorts of extra costs to mark ammo, figure out which state it will be sold in and whether it's marked. The police and military don't want the extra cost, people who shoot don't want an extra cost...I think it's a fringe idea. And the military contractors have a lot of influence with the government, they have the money to shut down a couple guys with a bad (or good) idea.
