I don't know much about grouse hunting sorry to say. Most of my buddies have got a tail or two hanging on the wall so when one flew into a tree 25 yards from me when I was walking up to a doe I just shot with the Parker, I nocked another arrow and let it have it. I do see them occasionally though, usually flying away lol. I don't know what is a good population measure, but I deer and turkey hunt so Im in the woods 5 months a year + scouting and maybe see a dozen grouse a year. Im sure you could kill a couple up here though if you know where to look, becase I don't.
