Please don't take this as an insult.....as I'm just talking about the buck as he scores, right now. I just don't see 150". I'd say around 142. I just scored him (in my head) as an 8 pointer and then added the G4's.
If these guys are going on his full growth potential.....then I hope they're right! My '07 buck looked to be about 115" in velvet.....and scored 103" when I got him back from the taxi.
Good luck with him.....and I wouldn't let him grow another SECOND if I saw him.
