Proposition 63 requires anyone selling ammunition to have a license from the Department of Justice. Ammunition purchased over the internet must go through a licensed ammunition vendor.
Under the law, ammunition means one or more loaded cartridges consisting of a primed case, propellant, and with one or more projectiles. It does not include blanks.
Prop 63 also forbids driving ammunition across state lines.
In 2019, the law will require background checks for anyone buying ammunition and will require vendors to electronically track ammunition sales and transfers and submit them to the Department of Justice where they will be kept in a database known as the Ammunition Purchase Records File.
