I still think the first one was young, not ugly and grizzled, not big-boned
the second was coarse-haired, grizzled all over, coloration "bled" the lines, longer snout, looser skin, just kind of ugly. he probably was past his prime and had smaller antlers because of it--- my opinion--- a good kill since he's likely been top dog a few times and lived his good years, still a shooter.
the third has oddly skinny back legs but other than that he's "burly" enough to be in his prime or just past it, skin is looser and his grayness is almost total. good antlers.
I didn't realize you were shooting some of those late season, that makes a big difference! also, none of them have big back legs and the heads look a little smaller than what I'm used to seeing so that throws me off a bit- I'm from Missouri and they're bigger in the butt here. For a tie breaker on one that you cannot decide it's age- DOES IT STINK SO BAD YOU CAN BARELY SMELL AN HOUR AFTER YOU SKIN IT? I got an old guy once that was almost completely gray, antlers were not great, huge skeletal frame and very heavy weight (over 220lbs after gutting, I know because I couldn't pull him up on his rope and I'm that much or more in gear) but the skin was loose and his muscles looked deflated. his snout was obscenely long, he was basically an emaciated pony- with antlers. I didn't even try to make steaks out of him, I put him into a crock-pot and slow-cooked him like brisquet. the individual fibers broke away from one another but they were all tough to chew, and had the flavor of tarsal gland scent. barely edible. I brewed up a lot of barbecue sauce to choke him down
if you get one that old, let me know, I'll send a recipe.
