Can't really age from that pic, but on score I would guess 130 but I'm no expert.

First, nice buck. As stated aging is tough from an ideal broadside photo but this is even tougher. That said, I think it would be safe to bet that this deer is 3 1/2+ Aside from assuming this is a "rut" photo, his chest and neck are well developed so no one should fault you for deciding that he is "mature". As for score, even more difficult without having a full object to compare to ie full body shot, tree, feeder etc. I would put him north of 130" but think 140 is a bit on the optimistic side. If you need a comparison, this buck is 3 1/2 and ballpark 145 now. Keep in mind this was a July photo.

Scored plenty of bucks with very similar frame, I am in mid 120s with that pic

He has the frame of a 130's deer and appears to mature in that one pic. Need better pics though as he might not be as old as he looks in that one pic.

Thanks guys it's the only photo I have of this guy my granda and I are trying to shoot the older mature deer and was wondering if he would be ok to take

125 to 130 and looks mature from the one pic.

Hats off to you for making an effort to practice good management. Far too many "hunters" out there that don't view things that way. I'd bet that that most hunters in TX would send him to his maker without thinking twice. Is he the oldest buck on your place? No way to know, unless you're high fenced and don't have any strays. Is he mature enough to harvest? I think we'd all agree that he is if the photo is an accurate representation. Just depends on what your definition of mature is. Let us know what you decide to do. And good luck
