I'm pretty sure he is 3.5 He put on over 20 inches this year. He is a local and I think as long as none of the other guys on the lease get a chance to shoot him he has a good chance of making it till next year.
I've shot 5 bucks in the 130" range, And a 168" buck last year. I would love to see what he does in a year, I think he will blow up.
Shoot him.
Eat him.
Mount him.
Or if you're Jesse, you'd
Shoot him.
Mount him.
Eat him.
Take him to the taxidermist.
Given these details, and in your shoes, I would pass. You have at least 2 yrs of history to know he put on 20". This tells me he has a "chance" of making it to next year. You have a solid track record with nothing to prove to anyone. Let him ride brother.
For me personally this year? I would be shooting.
