Wolf hunting in Idaho is plentiful and abundant in the right areas. In the north, such as were we are, Clearwater county, Wolf's are abundant and often a nuisance. Just last week, while building a chicken coop, we had a mother and pup try to coax our dogs away not more than 100 yards away. They are getting to be not so skiddish around humans and my 2 cents on a call, Nothing works better than a cow and Calf Elk call. The prey in distress calls are used so heavy, they often don't work in this area but, Elk or Mosse calk and cow calls work flawless.
My weapon of choice has been a 243 AUK pushing a 58 Gr V-Max at 4150 through a 1-10 twist Hart.
If your ever up near this way, Clear water county, shoot me a PM and I would be glad to give you a up close review of what a Wolf looks like through our Binos or if in season, through a scope.
