Should the cams be level and the string come off at slight angle as it goes up over the rail or should yokes be adjusted to tilt the cam upward so string comes of the cam in a straight line? There would be less string friction with cam if string comes of straight. My bow is Tormentor Whisper 380 if that makes any difference.

My Tormenter cams sit in the middle between the top and bottom of the flight deck. Seems to work fine. This year one of the limbs hit a tree while firing on a deer. The string came off and the bolts holding the bow to the flight deck broke off. I replaced the bolts and put the string back on. After sighting the scope back in it shoots as good as it always did. It’s one tough bow.

Thanks for the reply, Fred, and thanks for sharing about the incident with your bow. Good to hear it is a tough bow.

Are your cams level in the limbs or do they tilt up a little so the string comes off in line with the groove? Or is there a slight change of direction in the string where it comes off the cam and heads uphill to the top of the rail?

I guess level cams may be better because if the cams tilted up then the angle of the cable coming off the bottom side of the cam would be at a worse angle than with the cam level. Probably best to split the difference of angle change between the cables and the string.

I shoot the Barnett Ghost 410 and Barnett Buck Commander BCXtreme 365 Ultra Lite. These crossbows are very similar as yours in regard to tuning.
I time the cams in the uncocked position. They are then checked in the cocked position. The reference point in the uncocked position should match. The reference point in the cocked position should match but will be different from the uncocked due to cam position.
The cams should be level in the cocked position. To check, lay a field point equipped arrow on a cam, point facing the rail. Take another field point equipped arrow and place on the other cam. If the cams are level the arrows should lay on the rail with the points matching.

All the best.

To all a FYI..Just put a new scope on my centerpoint sniper 370 so I started by leveling the limbs after leveled the limbs I put the level on the rail and it was off. I was like what the hell the limbs was level and the rail and all the way to butt was twisted I purchased the crossbow that way anyway I loosened the bolt at the top that holds the limbs assembly to the rail after I loosened the set screw first and there is a lot of play in between limbs housing and rail go together so I rea leveled the limbs and leveled rail with limbs it was a pain in the butt with out having a Vice to lock crossbow in. I'm sure they should be straight did not have any problems last year with accuracy but it was just bugging me the way it was you would think centerpoint would make them 2 parts a better tight fit so they don't get out of line.

that's a good question,Bills,iv'e seen numerous posts here say level the cams,but the string sits above the cams ,do the limbs take up the angle.or are you supposed to adjust the cams to follow the string some what we need a xbow engineer here!

I wouldn't think the yoke should be tilted I. Didn't notice up and down play just side to side when I leveled my limbs then leveled the rail the rail was twisted like 1/4 inch you would think the rail and yoke would be machined for a tight level fit.
