Could be pass-thru. I'd have to say though, I'd truly be amazed. We killed a 4 1/2 last year and he was 15 lbs lighter than this one. This one was another foot longer in body than that 4 1/2. I haven't shot a 2 1/2 in years, and had my scope on one when this one came through. All I saw was a big neck and mass....that was my indicator of a shooter. Also I couldn't imagine a 2 1/2 picking fights with a 4 1/2 or older as much as this one was beat up. A 3 1/2, I might believe. Still though, I truly believe he is a 3 1/2. I will say he is one of the heaviest weighted deer we have killed. They just aren't nearly as big as other locations for whatever reason
