[QUOTE="keithcandler, post: 1796180, member: 3728"] Stainless on Stainless can be a nightmare if there is no lube. Whether you are dealing with actions or muzzle breaks/tunners on Stainless barrels. You need a high pressure, high temp lube do to heat of the barrel so the lube will not break down. This lube is outstanding and very affordable, used in the aircraft industry: [URL]https://www.ebay.com/itm/AeroShell-Aeronautical-Grade-Molybdenum-33MS-Grease-in-4oz-6oz-and-12oz-Pails-/392542227840?var=&hash=item5b65570d80[/URL] I have seen some muzzle breaks gaul, stainless on stainless barrels, it is a nightmare to deal with. Using non trued actions with factory recoil lugs on Remingtons, I get a .002 or less compression when I torque at 60-75 ft/lbs. I thread with pretty tight tolerances. A friend, Steve Hendry, was Utah State Benchrest Champ many years. Steve was head of the Fighter Aircraft Repair facility in Ogden, Utah for many years, a Tooling engineer. A tooling engineer is a machinists, machinist. Steve warned me about not having enough torque on my barrels, and he torqued all of his barrels at 100 ft/lbs. Steve said that loose fitting barrels were a cause of flyers, they found. Steve used Stolle Panda's, Hall M, and Remington actions. Steve did not believe in cutting real tight threads(class 3) on non trued actions because there needed to be some slop so things could mate up. Threading is a science in and of it''s self. [/QUOTE]
