I took the advice of my buddy who is shooting IBO Open Pro and was consistently in the top 3 at Worlds in MBR.

I set my pins for MBR on 5 yard increments out to 47 yards.

Mine go 28,33,38,43,47 (the 47 keeps the gap a little closer for a 45 yard shot and at the max I know I will see)

There is a couple reasons for this........you are never more than 4 yards off a pin, it gives you more precise gaps and the vast majority of the time ranges set the targets at odd yardages. 33, 37-38, 42-43 and this gapping allows me to take dead aim at more targets tham I am "gapping" in between.

I shot the same philosophy when I was in HC and it worked great for me, I always had big X counts in any shoots I entered. In HC I set them a little different with a lower starting point.
22,27,32,37 with only 4 pins.

You live and die in HC big shoots between 27 and 33 yards. My advice is to make sure you center the pin you expect to use the most. Trust me on that. Your whole body relaxes when you know the yardage and its the pin sitting in the center of your sight ring.
My advice is to dead center the 27 on a HC set up.

I only ever shot3 Hunter Class Nationals but took 3rd at Erie in the 2nd Leg of the Triple Crown, and was 2nd after the main part of the IBo Worlds with 20x's (That was the highest X count for any class and any shooter that year) and won the ASA NAtional Pro/AM tour stop in PA. All with the same bow and the same set up.
As long as you have a bow shooting in the 280-290fps range those gaps work fine and are very precise.........get much over 300 and into the 3teens and the gaps start to get a little too tight for my tastes.

If I were setting up a HC sight today I would ABSOLUTELY set it up just like I did in 05'
