I've never used a torque wrench to tighten barrels. You take the crush value and then calculate the index angle. Hand tighten the barrel, scribe a line on the barrel and the action. You then you scribe another line on the circumference of the barrel indicating the distance the barrel needs to be turned to tighten to achieve the proper crush fit. I've used this method on my long range prone match rifles, centerfire benchrest match rifles and hunting rifles that I've built, never had any issues. Unless you're looking for an excuse to buy a torque wrench... 😉
