Democratic Assemblymember Roger Dickinson says this tax would be different.
The bill would impose a five cent tax on each bullet or ammunition item.
The money raised would go to a school-based early mental health intervention program that was cut from the budget last year.
"I don't think we necessarily need to start taxing everything," says Dickinson."But I do think there are selected and targeted areas where it makes sense."
But Sam Paredes with Gun Owners of California says such a tax would be unconstitutional.
"The state cannot select an industry and impose a special tax on them if it places an undue and unfair burden on the exercising of a constitutional right," he says.
