I looked your buck long and hard in the pic's Red and I still would guess him at about 3. He could be an older buck that has small nuts or something that's holding him back! LOL. He does have a deep front end but his lack of sway back, graying face, and belly drag don't give me much confidence of him being all that old. BTW, my brother shot a 21" wide 6 pt this week that will age out close to 10 years old. He field dressed 189 pounds and looked like he was every bit 10 years old. No telling how many hunters that old boy encountered in his life on public land.:laughing
