I have outfitted bear hunts for several years and am still definately NOT an expert on sizing bears. The dark pictures are very difficult to see but the one bright daylight picture relays that he is a very nice mature animal. I am going to guess him between 300 - 375 lbs. The black bear is a decieving animal to say the least and it seems inherent to overguess them while alive, but in this case I thing if anything I have underestimated him.
