your probably right dave... i figured if you locked the nut on the barrel with the jb weld then the nut would act like a shoulder...but very well may not... im not going to find out...lol...

You do double jam it and let the JB harden in the nut threads. For re install use an action wrench and barrel vise. You loose the advantage of the adjustable nut because you just converted it into a permanent shoulder specifically for that action.

Sounds good in theory so how do you get the nut set at the correct head space without tightening the nut and double jamming all those threads to do it???


i wouldnt tighten the nut super tight... set the head space then just snug the nut... let the jb weld set up then the nut is fixed... break the barrel loose and take it off.. then you should be able to screw it onto that same action and the head space should be right.... now you couldnt screw it onto a different action... it wouldnt be head spaced for any other action..

It may work but it's not going to be as easy to get the headspace set and the nut locked as it sounds.

Will the JB hold? I don't know but I think there's a pretty fair chance not considering how thin it will be between the threads. Getting the nut positively locked up would make it work. Getting the headspace right while keeping enough JB in the threads while the JB was in the right stage to get the best bond would be the trick I think.

I think putting a set screw in the nut, setting the headspace and tightening the nut would be way easier but I think I'd have to drill through the hole in the nut and make a dimple in the barrel for the screw to engage before I trusted trying to take it off. Then it's a one action barrel like a shouldered.

By all means give it a shot 😂

I see this same idea on other forums occasionally. If I were going to do it I'd drill the hole and use a set screw into a dimple. Then you could still set it up on another action jamming the nut if you wanted.

Edit, this idea puts the faith of the whole thing staying tight on a set screw, maybe not such a good idea.

I agree with everyone's ideas in theory and think it might even work 1x but I doubt the integrity of the JB bond to repeat it multiple times.

i personally  wouldnt try it... i like the ability to pull a barrel off and screw it on a different action... as far as the jb weld holding... i dont think you could get it off there if you wanted after it set up providing the threads were good and clean... years ago i had a saw that the muffler bolts had striped out the threads on... i got the bright idea to but a dab of jb weld down in the holes the bolts went in and then snugged the bolts up the best they would... about a year later the guts broke in the muffler rattling around and loud as heck... i bought a new muffle and went to take the old one off.. all 3 of the bolts broke off just outside of where the jb weld was...lol...

You know me well enough to know I would not go there without knowing it was a solid option. I’m a barreled shoulder guy. Always have been and will not dabble with the nut. I even have a Savage action that has a shouldered barrel because I didn’t want a nut on the after market barrel. I’m sure it is convenient and works well for other shooters. It’s just something I have chosen to detour around.

I've seen you, you're not barrel shouldered 😂🤣😂

True!

Suspect you knew I meant “shouldered barrel”.

A true shouldered barrel might be Stacy Abrams, the round mound of sound.

Next project: savage switch barrel! Thinking about loctiting the nuts on and using a small 10-32 set screw in each nut with a matching pocket in each barrelto recieve the set screw. If i headspace each barrel to its corresponding barrel nut, then if i figure out how to r&r each one in a timely fashion in a field situation then my goal will be accomplished.
You guys get to kick me in the butt if you ever see me.
Today I started another switcheroo of barrels again, one of the "red loctited" nuts had to be removed as i set headspace! The stuff really was stuck so i dismantled my annealer to utilize the torch to heat it. 5 minutes and I was able to turn it right off!
The project today also resulted in a broken scope rail bolt, which probably was partially damaged when I torqued it on last time. The "fat wrench" had a lot of grip. Last  time was in March after i returned home from the horsepistol.
I have a tiny 1/16 bit with a hex drive that I first drill thru the screw and then used a slightly bigger bit to enlarge the first hole. When the second not broke thru the bottom it spun the screw all the way through at the same time
 I didn't have a tiny easy out for the first hole. I sometimes use the tang of a small file as an easy put nut lacked that also. All in all o figured put my dogs on two rifles this week. The fedralvprimers were culprits in the ones I tore down also the magnum cci250s too. The headspace was loose in two of the failing rifles.probably too much of a hurry. Still haven't got even one rifle good enough to bring west yet. My 6.5-06 shot ok the other day with last year's reloads. I have plenty of those left to hunt with. Also one 6.5 creed barrel shot ok nut had FTF with that also.
The headspace on that one was also loose! Lots of monkey business trying to get ready for the trip.
Next on my list is the silverado lost oil pressure again
  It dod also last year and turned out there is a tiny screen under the oil pressure sending unit that filters oil going to the active fuel management lifter manifold. Changing the oil pressure sender unit was quite a chore. I had to lay on my belly on top of the engine with my feet in the battery box. Not a pleasant job at all the new screen comes with the opsu. That fixed the problem for last year's trip. Good I'm pressure the whole time. The dash warning " low oil pressure stop engine now" is an eye opener.
Probably tackle it this week. I still have the special socket that you need to remove it.
Send some good vibes my way. Online searches said throw the screen away. So did a friend who just went through the same crap. My son has a 1 year old silverado and twice this summer towing the race car it shot the bed on him.
There is electrical solenoid that cut oil pressure to some of the hydraulic lifters. When on down hill grades it goes into 4 cylinder mode to save gas
 I read the lifters can be damaged if run without oil pressure...dah...my son is away for a end of season race, he was lucky his was under factory warrantee still and it was fixed both times by a gm dealer. It so hard to get to that it need a hole in the firewall to access it. Wish it had one.
We've had freezing mornings for a few days now and geese are flying every evening.
I got to get caught up on these trip preparations.
Today the loctite that you guys suggested not to was a time killer. Next project is to add .015 to the head end of one of my headspace gauges.
I have a PTG go gauge for 257 Bob Ackley that was lays too short and I measure it today  as i had the 6.5/257 Bob SO barrel off and put it on another action. That was my go to rifle last year and I still have some ammo leftover.
