OLYMPIA, Wash. – A new ammunition law will be taking effect in Washington state next month.

Starting July 1st, the sale, import, manufacture, or distribution of ammunition magazines with more than 10 rounds will be banned.

The only magazines allowed for sale and import will be those with a maximum capacity of 10 cartridges.

The Second Amendment Foundation and other gun rights organizations filed a federal lawsuit this month, claiming the new law violates constitutional protections.

Attorney General Bob Ferguson has said he will vigorously defend the new law.

He says all seven federal appellate courts that have heard challenges to similar laws have upheld them as constitutional.
