I have found mature bucks to be less palatable than does, fawn, and bucks a year and a half old. I shot a doer one time that was so old the DNR's white tail specialist could not age it other than to say it was 13+ years old. Without being prompted he asked if it was shot in Price or Bayfield County. I told him Price, and he was nodding his head and smiling. He said those were the only two counties where deer lived to be that old. This was prior to the return of Timber Wolves to that area.
As old as that doe was she still tasted better than an adult buck in rut or near post rut condition. However she was tough.
My favorite venison comes from young deer and that is what I shoot.
There is a gigantic 16 point buck living on our property in the valley of the giants. Potentially over a score of 200. If it walked by me in the stand I may indeed shoot it. It appears that this buck has survived our lengthy bow season and gun season.
