BARREL TORQUE

[std7mag]

I've heard for years that barrel "torque" was "about 80 ftlb".

I've personally never seen the torque display on the hammer i use on the action wrench.

Proof Research has a video of them just hand tightening a barrel on.

It seems that the consensus for the correct CF barrel torque is between hand tight & 80 FP.

I torque to 85 w bearing grease.

This was my scientific approach that I used to arrive at this number.

Many very competent ppl say 100-125 lbs. Wayne Campbell told me he torques to 60. Tony Boyer told me he had no idea what he torqued to. So I picked 85 and try to be consistent.

I've searched the archives and read where a well known on here 10 years ago said 40 ft. lbs. . Read recently here where he now says 100 ft. lbs. The numbers are all over the place, 40 up.....to whatever.

Like Greta Tunderbutt says it climate change

69 ft. lbs Just because I can.

One day im going to tighten one and see what its torqued to

I was thinking the same thing, however I give it a good snap and not sure I could measure it. If you used a torque wrench to remove it right away, would that be a close measurement?

Doubtful, breakaway torque (static friction) is not considered to be an accurate indicator of preload torque...

Yes and another factor is that when disassembling the motion is with the thread pitch not against it so that contributes to a different value.

Machinist Handbook will give torque for thread size, pitch,lube no lube,material.

You mean you don’t tighten ‘em?

I don't believe that is what Dusty is saying. I believe he's say basically the same thing Mulligan is saying. Tho I have been wrong before.

I just mean im going to install one normally then put the torque wrench on it to see what i torqued it to. I suspect its 40 or so.

Ok, let me see. Buy a precision action, stock, trigger, scope, rings, buy and make quality brass, buy or make quality bullets, weigh charges, and then slap a barrel on without any repeatable precision at all. Ok then...........

I think the key to all this is consistency. Whatever one torques to or lubricates with - do it the same every times the barrel is installed.

[Mr.Knowit all]

50 ft lbs for me .

Works for me too. I had heard 45 pds. even.
I believe Surgon Rifles posted something on their page a while back....

 

[rardoin]

Do you ever use SPOT Torque Norm?

I prefer the German universal torque spec- 'guttentite'

 

[Damon555]

No one is going to like my answer......"2 whacks with a 3 foot 2x4 hasn't failed me yet!"......but I have acquired a torque wrench since my last barrel install.
