It totally depends on how your bow is set-up, and what speeds you are getting out of your set-up. I personally set my pins at 24, 32, 40, 48, 55yds. These gaps are what I find allow me the safest margin of error for a misjudged distance and still result in VENISON in my freezer. With most of my bows, LONGER axle lengths, 36, 37, and a 40, I can set a pin at 24 yds, and hold that pin right on at 5yds, and be dead-on, walk back to 10, and be 1" high, 15-17 1.5 - 2.5" high, 20 will be about 1" high, and dead on again at 24. I've heard LOTS of guys claim to shoot ONE PIN dead on out to 30-35yds, but if you look at a trajectory for a 350fps projectile (which is a speed VERY few of us will ever see out of our set-ups), you'll quickly know they are either full of it, or are somehow compensating to be shooting "Dead on." My set-ups are mid-upper 260's and low 270's speed wise, so both have a very similar trajectory, and I have set my pins exactly the same on both bows because of this. I have a 3rd bow that is an older 60# bow, and the gaps are a little wider, and I have it set at 20yds. Not likely to go to the woods with me, just a target bow for now.
