For argument's sake- lets say you found yourself having dinner with the world's foremost WWII historian- what would you ask them?

Neither ignorance, nor obstinance are suitable counters to cognitive dissonance. You remind me of those so called Christians who go around yelling at people, "You saved? You're going to hell if you ain't saved." And then determining they're going to hell because you were dipped instead of submersed.Or because you say "Yeshua" in stead of "Jesus". You might want to get the tre out of your eye before you go picking at a splinter in someone welses. Grow up.

Barrel Torque Ludicrocity

Really though. 100ftlbs for prefit barrel torque? Fuck, I know this isn’t necessary. AR15 armorer schools is min 35ftlbs unless old school barrel nut needs advanced to next cut out for gas tube clearance. Then it’s 35-65ftlbs range.

I run 55ftlbs on my bolt gun Savage style barrel nut torque. Easy on off with anti-seize. 300WM too.

Seems excessive in regards to thread distortion and will a 35ftlbs barrel ever shoot loose? No human can spin loose a 30ftlbs barrel.

Somebody may have answered this in the 4 pages I didn't read but they didn't on the first so I'll provide my understanding of the reason.

The reason for very high 100-150 ft lbs of torque on a barrel is not related to the barrel coming loose. It is related to the amount of elastic deformation you will get in the threads during the shot. Because the bolt lugs are in the receiver on the types of bolt gun we are talking about, the immense pressure from a shot will be applied to the threads between the barrel and the receiver. If not substantially pre-loaded by a high barrel torque these threads will stretch a lot further than if they are pre-loaded. This stretch makes the chamber temporarily longer during the shot resulting in over-expansion of the brass and a likelihood of stuck cases. I'm sure it's also not ideal for your accuracy but I doubt that is really as big of an issue. And yes, I did notice that Ted became very obsessed with the problem of stuck cases right around the time of the barloc system.

As for barrels with extensions containing the lugs such as on an AR or on some euro-ish bolt actions, they don't require high torque on the barrel nut because those are not the threads that will be loaded by the chamber pressure. The chamber pressure loaded threads are between the barrel and the barrel extension in that type of system. As such, it is much easier to make a switch barrel system if your using a barrel+extension system than one with the locking lugs in the action.
