Spear Hunting In Montana

Surprisingly, it's not legal to use a spear for hunting in Montana.
But that might change: Stone age hunting bill sails through committee.

Cavemen of Montana, be grateful. Repugican State Senator Greg Hinkle of Thompson Falls failed to establish a hereditary hunting aristocracy in Montana, but he’s having better luck legalizing your right to practice one of the most primitive means of killing animals: spearing them.
That’s right: on 14 January, the State Senate’s fish and game committee voted 10-zip to send SB-112 — “An Act Providing that a Hand-Thrown Spear Must be Considered a Lawful Means of Hunting” — to the Senate’s floor. I expect it will pass handily.
Hinkle’s Stone Age Hunting Act of 2011 will apply during the general rifle season, allowing hunters for whom killing a deer with a high-powered rifle no longer provides enough of a thrill to tie on their loincloths, grab their flint-tipped poles, and run through the forests and meadows, spear arm held high and back, trying to close to within skewering distance of Bambi.
