Yes - back the limb bolts out till the rigging is loose then take the cable off the outer post of the cam and add 2 twists tighter to it.
Do the same to the other cable on the other cam.
Then tighten your limb bolts all the way back in and see what the measurement is from the post to the cable.
If it is at 1/8" - then measure your axle to axle and see if it is still in spec.
If ata is short - back the limb bolts out again and take one twist out of the shooting string.
Tighten it up and check again.
After you add the initial twists to the cables and tighten it back up - you will be able to see the amount of change it made and will
know what to do to get it where you want it.
