Montana's News Station (actually a chain of CBS television stations in that State) reports that the Montana House of Representatives has voted in favor of their sovereignty resolution in a second reading. Strictly speaking, Montana's HB 246 is a bill to nullify Federal firearms statutes within the State of Montana, something that to my knowledge has not been attempted since before the War between the States. The bill still faces a third reading in the House and votes in the State Senate.
