I sometimes wonder why folks recommend shooting cows or does. BFDs, or big fat does, of course, are always fat supposedly. Alhough I have not found this always to be true. In fact, the does might, more often than bucks, be old and skinny and tough. I find it is hard to tell under that thick winter hair, when the light is bad, the view partially obscured by brush, and the animal moving along.
Indeed, the best eating ungulates for me tend to be spikes, raghorns, and young basket racks, if only because I can tell their approximate age with much greater accuracy and much more quickly than evaluating the sway in the back or the length of the nose of a doe or a cow.
Make my meat animals spikes whenever possible, please.
