My guess would also be around 110-115. I'm guessing 16 or 17 inch inside spread. Probably 20 inch beams. I'm only seeing about 45 inches per side. His G2 and G3s lack length, but he has awesome G2s!
I really like the look of him. Your best bet is to just download a scoring sheet from Boone and Crockett for free, and take the measurements. That's the only way you'll get a true score as pictures can be deceiving. I had my picture taken after shooting a 9pt buck this year and the picture made him look like a 115 incher and he ended up being 128. I have a 8pt buck getting mounted now that the pictures taken of him everyone swears he was ATLEAST 140, and he ended up barely breaking 130. The thing about it is the 8pt looks MUCH bigger than the 9pt...even though he's only about 4 inches bigger...
Every time I've measured a deer I've been just a tiny disappointed because I had estimated high. I don't know why I still bother....
Great buck btw.
