Question for you really long range shooters, how do you determine the quality of the animal your shooting?
I often glass out to 500 yards using Ziess 10 x40 but at any further distance it is tough to tell the quality of the animal escpecially in low light, or maybe my old eyes are just not what they should be. The longest kill I've had on a deer was 250 yards and that was doe so all I needed to determine was size and antlerless. I've only hunted elk once but was prepared to shoot 300 to 400 yards perhaps a little further but I had both cow and bull tags.
Not sure how you protect from ground skrinkage at those long distances, I see a lot of hunters miss judge deer inside 100 yards.
