Mark Carroll writes:

"Recently the Montana State Legislature passed, and their Governor signed, HB 246. HB 246 declares that any guns and ammunition made and retained in Montana are not subject to ANY federal regulation under the authority of Congress to regulate commerce “among the states.” It is under the guise of regulating "interstate commerce" that the Feds have stuck their nose in where it doesn't belong and claimed authority they do not have instituting all kinds of draconian gun control measures. HB 246 will become effective on October 1, 2009.

As you may have guessed, the Feds aren't going to put up with this, and the Bureau of Alcohol, Tobacco, Firearms and Explosives...[has] sent letters to gun dealers in Montana telling them they don't care about no stinking state legislation, nor do they care about the Ninth or Tenth Amendment to the Constitution."

Rich Beecher says a similar letter went out to gun dealers in Tennessee.
