On page 16 of the 2005 Big Game Hunting seasons and rules pamphlet under Prohibited firearms/hunting methods, it is illegal to:
c. Hunt game birds or game animals with anything other than a firearm, a bow and arrow, or by falconry....
An airgun is not considered a firearm, as far as I know... :cry: A call to your local WDF&W office would be prudent....
As far as the crosman, I've got a 377 break barrel, it's killed a possum or 2, just takes good shot placement as with any shot on game, behind the ear for those that were unlucky! :grin:
