I just emailed Tikka about this subject.I too was looking for torque specs and mailed them stateing I had tightened but wanted to know how tight.This is what they told me" You have done right.We do not give any torque values.As the bolts are tightened,
the barreled
action is sitting stadily in the stock and the performance is there.As the
barrel does not have a bearing point in front, the actual toque value is not
important." Regards Ruttinbuck
