I am not trying to be a smart aZZ here , but this is NOT a very big bear, that is maybe a 300 lb bear if that based on this pic!
small head, not very tall or wide
bears are super hard to judge, for sure, but a large bruin, would be a LOT bigger in a lot of places
a nice looking bear for sure, and healthy, but just being honest with you, I have a ton of experience with bears, from trapping, tagging, moving, helping handle them, and have done so for about 30 yrs now
plus I get bears at my place almost daily, so, I have an above average bear judging skills
again, NOT knocking you at all, as most folks see bears and always think there bigger than they are LOL
its human nature I think when it comes to bears
