Google it.
You just need the Boone & Crocket score sheet and a soft tape measure like a tailor would use. You can do it yourself and be close enough to not be guessing.
Nice buck. Mass looks good in the pics. I'd guess between 100" and 110" but that's far from anthing but a guess and only based on what I saw at this year VA big game contest. We can enter anything and have it scored and get a certificate for a small fee as well as be entered in the anual VA big Buck Contest. There were hundreds at this year's show!
I have 3 degreasing (Doing Euros on them) now that I am going to score myself for fun when they are done. One is a MASSIVE 9 Pointer skull that we found in the woods. I'm guesing that one to go 125-130ish.
