About the Serial ammo stuff currently on Factcheck(it is still good for some things.)

Such a proposal is being pushed by a company that holds a patent on bullet-coding technology. But none of the 31 bills introduced last year ever made it out of committee.

The legislation for serial encoded ammo has been initiated on all fronts by a 3 person company which holds hte patent for the tech to encode the ammo. Last year I was able to find sales figures for was 1992 with approximately 5.2 billion rounds sold for private(non law enforcement, and military) use. At 5 cents per round tax on the ammo proposed plus what ever the 3 owners of the tech will recieve for the encoded rounds it looks like ammo prices can get nasty. Fortuneately most states won’t ever get teh number to pass such legislation and it is unlikely that Obama will be able to get it passed nationally.
