Wyoming lawmakers have proposed a new bill that, if passed, would nullify any federal restrictions on guns, threatening to jail federal agents attempting to confiscate guns, ammunition magazines or ammunition.
The bill – HB0104 – states that “any federal law which attempts to ban a semi-automatic firearm or to limit the size of a magazine of a firearm or other limitation on firearms in this state shall be unenforceable in Wyoming.”
