Recently I bought a DB10BGB .308.
I noticed it was very difficult to achieve a decent grouping at 100m and, at the same time, I noticed the barrel nut was loose.
I brought it back to the gunsmith who sold it to me, he gave me back the rifle with the nut tightened but, after about 60 rounds, the grouping was again inconsistent. I checked the barrel nut and it was again loose.
Could someone share the procedure to properly tighten the barrel nut together with the torque specifications?
Thanks in advance for your help,
