[QUOTE="keithcandler, post: 1796216, member: 3728"] Mram10us, I am repeating Steve's exact words on the Torque subject to interpretation. I threw it out there due to Steve's incredible experience and shooting career. For a while I was in between lathes and Steve did my work, his barrels were on very tight, and I usually use 60-75 ft/lbs on my Torque wrench on custom and Remington actions. Steve's comment on torque and flyers would probably be a 5 hour conversation at least, thread fit, action trued or not, thread pitch dia. Steve's rifles shot very, very well in benchrest matches. From torquing so many bolts on aircraft, Steve may have been heavy handed on barrel torque, I suspected. When I took a barrel off my Stolle Panda that Steve had torqued on with what felt like a 6' cheater bar, I put it back on with 60 Ft/lbs. A lot of this stuff is subjective. I like to stress the use of a good high pressure/high heat lube that will not break dowin under heat and stress of which there are many. Savage Stainless barrel nuts need lube on them when used on Stainless barrels, and it is very important to use a lube on a stainless barrel with a stainless barrel when even a test fit while the barrel is even in the lathe. Stainless barrels used in Chrome moly actions need lube on them also, but they are not as prone to gauling as Stainless on Stainless. When I was shooting Registered BR, I too changed barrels with only snapping the barrel in place by hand. Today, I would want at least 60 ft/lbs of torque on a barrel using a custom action that I knew was true. This is just what makes me feel "good"...nothing scientific about my gut feeling at all.
