Hi everyone,
The Raptor has landed and began working on the specific dimensional data prior to being shot. The following is straight out of the box, riser mounted.
We measured a combination of 42 dimensions. These dimensions are what I consider critical for repeatable accuracy and stability. Before complete inspection of the cams I wanted to first know the bow is square and sound. Here is the following dimensional findings with a certified granite table and height gauge.

1- Main barrel from the trigger gate to the end of the barrel: The maximum error was .003" end to end, side to side.
2- Cam to each other at the most outside top edge. .012"
3- Cam lean; perpendicular to the barrel: +.006"/left, +.0085"/right
4- Cam tilt; parallel to the barrel: .011"/left, .013"/right
5- Riser parallel to barrel. .0095"
6- Riser degree of error to barrel. .67 degrees of error
7 Limb parallel plane to barrel. .009"/left, .012" right
Several of these dimensions required multiple points along the path with a total of 42 taken for accurate verification.
This bow will be shot this evening for initial "break-in" and be remeasured using the same standards to prove stability. The S&C need to settle in after mutiple shots to see if any dimensions increase in error.
I will say this much so far. I have completed this process on bows costing nearly 4-1/2 times more with greater out of the box dimensional error(s). I am flat out impressed with the quality of manufacture.
A welcomed finding is the string to barrel pressure. 2.4 lbs. with a certified force/strain gauge. (sorry, photo a bit blurry)
Some bows I have tested were up near 12 lbs.

Time to go shoot. Stay tuned........
