Rick,
I use Bostick "Never Seize". I haven't been able to figure out how to attach my torque wrench to my bbl wrench.
I just line up the extractor notches, and then make final adjustments by firing and moving bbl to align sight picture with point of impact of the bullet.
I have noticed when installing new aftermarket bbls that the extractor notch and front sight mount are frequently not aligned correctly. <img border="0" alt="[ouch]" title="" src="graemlins/c.gif" />
Quite often, when the sights are aligned to point of impact, the extactor notch will be offset to one side somewhat. <img border="0" title="" alt="[Frown]" src="frown.gif" />
