High 80's, maybe 190
A few things hard to tell- How wide? The one angle away makes it look "narrow" maybe 24" wide at most? That would affect the inside spread credit.
The other thing can't tell well is how long the main beam is. Looks like it curves in maybe, or just stops?
Also I don't see any eye-guards (G1)? Assuming he doesn't have them?
Lastly, I can see the inline on the rt, is there a matching one on the left?
I got lucky and shot a buck this year that has a similar frame to this one. The velvet always make them look bigger than they are, especially on the mass for sure.
Based on what I see his main frame 4x4 will be between 170"-173". Then you can add on the extra tine at about 6" on the right. That would but him just under 180", and over if there is an extra on the left?
