Maybe it's just his summer coat or not having "rut neck" fooling me but to my eye he looks a little young. If I'm seeing it right he looks to be around 3.5. I could be wrong on that but if right, and you want to see some big mature bucks on your property, I'd let that bugger walk this year and maybe next. Let him spread those genetics around. He is most definitely a fine deer with some great mass. I don't trophy hunt myself anymore, other than culling for a few properties, I could care less about a rack but I do try to manage my properties for high quality genetics and health which good racks signify. That buck sure is one that would make my trigger finger itch damn near off though!!
