Good question! Here's my 2 cents. First off, the poundage is immaterial. There may be some differing opinions on that, but this is MY 2 cents, lol. I'm guessing you are talking deer, so will say 40 yds max and half of that preferably. They are all pretty similar to a 60# compound in performance. I have both a 175# and a 225# and won't take a shot on a deer past 35 yds. I can keep my b-heads in a 3" circle at 50 yds. [w/ rest]which is fine for rabbits and coyotes, but not for deer.
