I know more than a few Fclass and PRS shooters that use the same style of "torque system " and they have no issues with loose barrels- and regularly place high up in big name matches for that matter !

I just looked at Stolle's website, they suggest 100 ft/lbs for their Panda action. I sure hope my buddy's 6.5 CM barrel doesn't fall off his F-Class gun because I only screwed it on to 65 ft/lbs. It is set up to zero headspace at 65 ft/lbs, at 100 ft/lbs it might end up -.001-.002 headspace.
Didn't one of the action makers recommend whatever the barrel maker suggested?
It's actually over 500ft/lbs.
Google it. It's not somthing they advertise, I just recall reading about it. They're legit company. Tac Ops has been making rifles since the 80's. I think their rifles are caters to military and law enforcement use.
I talk to Mike regularly. It’s over 500.
I know zermatt arms has it printed out on their action wrenches and goes up depending on the bolt face. I think magnums they recommend 120 if im not mistaken.
500 ft-lbs is silly. The axle nuts on a typical car are around 150 - ever tried to loosen one? At 500 ft-lbs there exists the risk of permanently distorting the action, or inducing very high levels of stress at the barrel receiver interface. Combine this with the stresses of shooting, and you are potentially looking at a bomb. Perhaps they meant 500 inch-lbs....
Not with a modified buttress thread there doesn’t. Critical fasteners in the same diameter range are routinely torqued to over 1000ft/lbs, and that’s with as standard 60° thread form.
Tok - I appreciate your comment. When the application requires it, say flange bolts on very high pressure piping, large amounts of fastener torque are required to load the gasket. This is calculated by engineers (I have done it), and bolt material of very high grade (eg SA-193-B16) is used. The bolts are tightened very precisely using hydraulic actuated wrenches.
However, the Tac-Ord website talks about Rem 700 actions, and Krieger barrels with presumably standard threads. I cant possibly see the upside to torquing to 500 ft-lbs.

They are not standard threads. I told you that. Just like I told you bubba torques them north of 500ft/lbs. You don’t have to believe it. That doesn’t make it false. The rifles do what they do repeatably, like nothing else available. Those are only two of many ingredients in Mike’s secret sauce.
No. Ridiculously. Your lack of understanding doesn’t make something bull####.
