Ammunition Background Check Laws

California Lt. Fool Gavin Newsom is pushing for an ammunition background check law, presumably because the gun background check law has disarmed the vermin there, who are using the ammunition as a threat: "Open the cash register or I will throw these cartridges at you.".  No other state seems to have an equivalenty law, but New Jersey and Illinois do require a firearms owner ID card to buy  ammunition (for Illinois) and handgun ammunition (New Jersey).  I am working on a paper analyzing how effective such laws are.  Does any other state require a license or ID card to buy ammunition?  Please tell me.
