Big enough as far as I'm concerned.
Gross: High 170s in the typical photo. Touching 180 in the non-typ photo.
I'd put Bitterroot's estimate real close. Looks like the back forks may be a shade weaker now or else it's just the angle. All the cool extra points more than make up for the back forks.
Now i am ALWAYS conservative... But I have to go more.. I'm going 185-190, but maybe because that 2nd pic is literally my all time dream buck... White face like that... Yikes.
