There are very few states that a rifle can be used. However in all states a shotgun can be used.
And to help you find a spot to hunt in just about any state you may do business in - use this link from the National Wild Turkey Federation. Click on just about any state once you have it open and it will tell you all about that given state's Fall turkey hutning opportunities.......
