he is wide and his tines have a lot of growing season left. I would gamble that he might sprout a g4 or two. He looks to be filled out well with a big neck and decent mass. I would say he is atleast 3.5 based on those photos. good luck with him.
I would say that buck has all the makings of being a monster... He reminds me a lot of a buck I have been getting pics of for the last 3 years on my farm. Do you mind me asking what county these pics are from?
