Tell me why this won't work

So, let's say you have a Savage barrel with the nut. Let's say you set the nut and headspace BUT you put red Loctite or similar adhesive on the nut.

Add an index mark on the bottom of the action, and mark the nut to the index mark.

Then you could remove the barrel after the adhesive set and the nut now is the shoulder.

No need to re-headspace the barrel next time. Just tighten to the index mark. Done. Just like a standard shouldered barrel.

You are right.

I bet it works, there's nutting to it!

I've heard of others doing this.

What if you had to replace existing bolthead that was used when you put loctite on that barrel, with a different bolthead? Due to tolerances varying between factory bolthead/parts the headspace might not work out like it did with the original bolthead?

It *could* work... I've done something similar by etching a witness mark from the receiver to the nut, and from the nut to the barrel. Line 'em up and you're awfully dang close.

Biggest problem with 'locking' the nut with loc-tite, etc. is that I personally don't have 100% confidence that it would *not* move, not even 0.001", if the barrel was on too tight and I had to gorilla-wrench it off of there. I've seen too many adhesives fail when they shouldn't have, hi-tech or otherwise, for me to be that trusting.

Same with a set-screw... but an additional worry for me would be damaging the threads on the barrel tenon. I've had much headaches from boogered threads as a result of scope base screws that were too long and when driven in mashed the barrel threads. Pretty sure I wouldn't want a system that *intentionally* drove a screw into those precision threads...

Theoretically, it'd work. Practically? : I ain't about to go this route.

I have heard of pinning the nut to the barrel.

Why worry about the loctite at all? How 'bout just using witness marks on the action and barrel? Screw the barrel all the way in, back it off till the witness marks, line up, and bring the nut tight to the receiver.

Well yes, of course this would work too.

I was hoping someday to pin my recoil lug to the action then I ultimately wanted to pull the barrel without taking the action from the stock at all like the bench guys do. My plan is to go to the barrel nut across the board on my guns.

I hear you about adhesives... Althogh they make a very high heat Red Loctite that is supposed to be awesome.

I mean I could tack with the tig I guess... hahah

Or a set screw system would be cool too...

Well then you would have to break the nut loose with heat and re headspace it.

You posted this on at least two forums. It works. It is not ground breaking. many have done it before. Where are we headed?

There was a detailed explanation of this very process in the VHM last year. Not uncommon at all from what I can see.

I didn't know that it was bad to post on more than one forum. Who knew??? I just thought I was trying to get more input...

Well, I did not know about it. I am still figuring out my plan.

The goal is to be able to change the barrel at the range without taking the action out of the stock (this is the same thing the benchrest guys do during matches all the time). You can't do that using a nut wrench.

Typically, to change barrels super fast without removing the action you need a shouldered barrel and a pinned or integral recoil lug. I've seen guys change barrels with a flat machined on the barrel that accepts a wrench with the stock between their knees sitting at the bench. They change barrels in a matter of two minutes and go back to shooting.... and the headspace never changes. No need for special tools either.

My final goal it to use prefits only from now on.... but I want to be able to do quick changes.

Pre-Fits are the future. There are going to be a whole bunch of prefit manufacturers soon. Barrels to your house in a couple of weeks. No need to send off the action. About half the cost too.

Hey bro. That's good to know. Do you know the issue?

Is that it???

Not sure if you've seen Larry Racine's way of the switch barrel.

Yes. I have read that and I plan to do just that.

I need to get my recoil lug pinned.
