Getting set up to switch barrel on a Rem 700 action....what is the approximate torque when using a rear port wrench? Any "tricks" that will make the job easier? What do you use as an anti-galling compound? Thanks
jackie: I've been using 65 ft. lbs. since the "beginning", ( hundreds of rounds fired with each of the 4 rifles), and no problems what-so-ever. With his more than 40 yrs. experience, my 'smith has never failed to provide me with excellent advice, yet another example of: "it works for me".
Calibrate? Why calibrate when we don't have a firm knowledge of what the torque should be.One point not mentioned is lubrication. This obviously lowers the torque necessary to load the threads. Just keep the type of lub in mind when looking at torque values - often expressed in dry, oil film etc.
Oh and don't forget the wonderful calibration requirements for those precise instruments.

I do wonder about some of these 40 year gunsmiths that suggest just snapping a barrel in place though.
For sure mine will be 100 ft/lb or greater, always.
Simple. Repeatability...which is one point we strive for. If your torque wrench can't hold accurate torques over time...you have inconsistency. The inconsistency may or may not translate to issues down range.
As stated, the elongation of a fastener is a far more accurate means of determining this over a torque wrench.
