If the guys on the next ranch kill him, he'll be just as dead as if you killed him.
If you want to shoot him, because he might make it to the next ranch and get shot by them, then you have the wrong mind-set.
If you let him walk then he'll have much more of a chance at living on your land than getting to the next property and being shot.
Is he a shooter? Personally, yes, I'd shoot him in a heartbeat.
"do you guys think hell grow alot more?"
He's going to be a high racked six point and isnt going to get much bigger, not this year atleast. IMO
Good luck.
If you do get a chance at him and decide he's a shooter, we'll want to see pics!
