Need some info....I'm TRYING to time the brake for my Sandman S on my Accuracy International AT...I have tried every combination with the shims and cannot find the right mix that doesn't put me 5-10 degrees past or short of 12 o'clock with the torque wrench...I'm also afraid to wrench to hard because I'm worried about hurting the rifle. Dead Air doesn't answer the phone so I'm in email purgatory ....Has anyone dealt with this before?
