Setting your center shot
The following info was shared with me some time back and have proven to be an easy and effective way of setting your center shot (on any bow).
If at all possible, mount your bow in a vise and plumb it in both directions.
Nock an arrow and then place a straight edge against your riser. Another arrow held against the riser with a rubber band works great. Measure the distance between your straight edge and the center of the string. Now measure at the front of your riser from the straight edge to the center of your nocked arrow.
1) Adjust your REST as necessary to get the measurements exactly the same.
2) Adjust your SIGHT so that your pin/reticle is practically hidden behind the string. This is where it helps to have the bow in a vise. Sight "through" the string down the nocked arrow.
3) Remove any target you have on your bale and replace it with a large sheet of white paper.
4) Using either a level or a plumb boob, draw a vertical line on the paper. I like to use a large red marker and make the line about 1/2" wide.
5) Stand very close to your target bale (6 to 8 FEET) and shoot for the vertical line. Do NOT concern yourself with the vertical point of contact (POC) as long as you're hitting the paper.
6) Adjust your SIGHT in very small increments, following the arrow. If you are hitting left of the line, move your SIGHT to the left - if you are hitting right of the line, move your SIGHT to the right.
7) Shoot enough arrows at this distance to know you are consistent and until you can split the line.
8) Now move back to a longer distance. For hunting bows, 35-40 yards is probably enough - target setups 55-60 yards.
If you do not already have a mark or pin for these distances, gradually walk back with your only concern being that you can hit the paper on the bale.
9) At this longer distance shoot for the vertical line again. Do NOT concern yourself with any aspect of the POC except the left/right.
10) Adjust your REST in very small increments, opposite the arrow. If you are hitting left of the line, move your REST to the right - if you are hitting right of the line, move your REST to the left.
11) Shoot enough arrows at this distance to know you are consistent and until you can split the line.
12) Rinse and repeat steps 5-11 until you find the "sweet spot". This will probably only take a couple of repetitions.
Just remember, when setting your center shot, move your SIGHT at the close distance and your REST at the longer distances.
Hope this helps.
