Using the 10" between the eyes rule I'd guess him to be in the low 40's. Not bad for an eastern Canada bull. I'd presume the moose rut there is still probably a few weeks away down there. Even clear up here in Alaska it's still about another week before it really kicks off big time. If you really want some good moose hunting pointers get a copy of the movie "Love, Thunder, and Bull 2" and get one of the "Bull Magnet" fiberglass megaphones. Bull magnets are great for calling, thrashing, and listening for any approach or response.
