The further out you go, the faster it's dropping. I use 20, 30, 35, 40, when expecting my shots to be 40 yards or less.

I personally just set mine at 20-30-40-50

I don't know if you plan on doing any 3d shoots or not. If you are, most of them set the targets out to 50 yards for competition. So I would go with 20, 30, 40, and 50. You probably won't shoot that far at a deer but you never know.

It depends a little on the speed of your bow. I have a relatively slow 50# bow. I use a three pin sight on it with the pins set at 10, 20, and 30 yards. I also have a very fast bow, that my brother-in-law tweaked up to a 78 - 80# pull (depending on the scale). The four pins on it are set at 20, 30, 40, and 50 yards. I can shoot 3D deer targets at 10 yards by holding right under the kill zone and at 60 yards by holding the top of the pin level with the back. I don't intend to shoot a live deer at 60 yards though. My brother-in-law killed a deer at 80 yards and shot 3D targets at 100 yards with it before I bought it from him. Sometimes he missed at 100 yards though. In all honesty, he misses the 100 yard target about as often as I miss the 40 yard target, and I'm a pretty good shot up to that point.

In most cases you will normally set each pin for 10 yard increments starting with the first pin set for 20 yards. e.g. 20, 30, 40, 50 & 60 yards. The reason for starting at 20 yards is because 10 yards and 20 yards are almost the same. You will probably aim a little low on your 20 yard pin to hit a 10 yard target. The other problem of setting a 10 yard pin is that most people will not be able to get within that distance to take a 10 yard shot. In most case, many bow-hunters are lucky enough to get within 20 yards to take a close shot. In upstate NY you may get clear shots up to 50 yards away. You will have to be very quite to take that 20 yard shot. It will be worse if yo are in a swamp area. Water can be very noisy. In some areas the area maybe open but if you are in a dense wooded area, noise will travel. I have hunted in the area around Watertown, Carthage and Harrisville. When hunters come into the area you will hear them and their cars miles away. You can hear them stomping through the woods. Carrying rifles or bow, they never see me watching them, they never hear me come or go and I'm only within 100 feet of them.

The others have given you some good advice on the setting of the pins. But you will find a single pin system works under hunting situations .There is no confusion when a deer is sighted over which pin to choose. Set the single pin for 25 yards and aim a little low at something a little closer and aim a little higher on the kill zone at something a little farther.Learn how to estimate your distance from the target and remember that deer will look farther away when you are 20 foot or so in a tree. Basically with today's bows you can aim dead on from 10 to 30 yards and still hit in the kill zone of a deer. And research has shown that the average bow kill is made at a distance of 18 yards. But I'm sure out west the average would be much farther away. For someone just starting out bow hunting the single pin is the best solution. Because it will work great out to 30 plus yards and until you gain experience you shouldn't take a shot much farther then that. You need to keep it as simple as you can when you first start out bow hunting. For some reason, when a deer appears it robs you of almost every drop of your concentration, especially when you first start out. Bow hunting .....The greatest sport on the face of the earth!!!!
