Tenth Amendment, anyone?

A Gun Activist Takes Aim at U.S. Regulatory Power

By JESS BRAVIN

MISSOULA, Mont.—With a homemade .22-caliber rifle he calls the Montana Buckaroo, Gary Marbut dreams of taking down the federal regulatory state.

Montana passed a law that tries to exempt the state from federal gun regulation. But the law is now before the courts, in a test of states' rights. WSJ's Jess Bravin reports.

He's not planning to fire his gun. Instead, he wants to sell it, free from federal laws requiring him to record transactions, pay license fees and open his business to government inspectors.
For years, Mr. Marbut argued that a wide range of federal laws, not just gun regulations, should be invalid because they were based on an erroneous interpretation of Congress's constitutional power to regulate interstate commerce. In his corner were a handful of conservative lawyers and academics. Now, with the rise of the tea-party movement, the self-employed shooting-range supplier finds himself leading a movement.
