I also think this buck appears 5 1/2 or older.
But based on this single pic, am a little more reserved in guessing an antler score.
Do think he'll break 130 gross.
Most of us have a tendency to over-estimate antler scores on bucks in velvet,
and a single pic can greatly mislead.
Despite the mature features, how do we know whether this is a small bodied or a large bodied buck?
If he's smaller bodied than most (about half are), that makes his antlers appear larger.
If he's larger bodied than most (about half are), that makes his antlers appear smaller.
I've been fooled many times, being off 10 to 20" on mainframe 8s & 10s, just be their being particularly small or large bodied.
