Never have I encountered this before, not have I ever heard of it happening...

I went to remove a factory 7mm Rem Mag barrel on a customers stainless 700 rifle that had never been worked on...

The barrel removed easily by hand... the 'Loctite was present but all powdery... just screwed right off by hand... I couldn't believe it. Customer has shot this rifle a lot in the factory bedding and said it didn't shoot great but not that bad either...
 
was there any noticeable wobble on the barrel before you tried removing it?

yikes.. i didn't know it was possible for barrels to come off by hand and i didn't know barrels required lock tite either? I thought on the contrary, people tend to put anti seizing compound.
 
I have never heard of locktite on a barrel. Most are timed and torqued or pinned in place. Anti-seize compounds or barrel assembly paste are used when working with stainless steel to prevent galling of the parts. If the barrel was that loose the headspacing could have become hazardous to the shooter.
 
Remington has used some type of Loctite on their 600/700 series barrel threads since day one... In the past few years I have come across a few more recently manufactured ones that had none, but the vast majority produced have some form of Loctite from the factory...

The barrel wasn't wobbly, just loose to screw off... headspace was not an issue, the barrel would have to be unscrewed some for that to occur.

Sounds about right. Any I have taken off took very little effort to take the barrel off. Only on guns with an aftermarket barrel on them did I have some trouble.
Most had substantial ammounts of red loctite in the threads. Not all of it powdered some still red and crystalized. Pretty sad a company making "quality" firearms need to put this much loctite on the threads to hold the bbl on.
 
I am certainly no gunsmith, but I have seen red loctite turn to powder on an assembly that was subject to vibration. I also note that you said the owner shot it often, perhaps it got hot enough to have an effect on the loctite.

Our experiences differ..

Of the over one thousand factory 700 barrels I have removed, the vast majority of them required a lot of force and when they broke free there was a very loud 'snap'... after market barrels never a problem...
 
Could the loctite have been cooked by firing rapid fire? It wouldnt take many rounds of 7RM to get screaming hot.
 
I had a Mauser 98 .30-06 built by Johann Springer of Austria at one time... noticed one day the sights seemed a little ####-eyed. Grabbed the barrel and gave it a little twist, next thing I knew the sights were on the bottom! When I took it out of the wood, the barrel came off by hand. Made it real easy to clean though.
 
I'm leaning towards the locktite being cooked. Like some have said above. But to be ownly hand tight. Either that or guntech is getting really strong!!

Only ones I ever had come lose with a snap were lee enfields. And those sounded like glass breaking and sent me on my ass.

I am with Guntech on this one I have not removed anywhere the amount of barrels he has , but the ones I have removed have required a good vise rosin and a big action wrench to get off with one requiring some heat.

LOL I realize its a different kettle of fish but I have a Rolling Block that I have a 3 barrel set for, a new 45-70, original 50-70, and 50-90. I regularly change barrels and just spin them on until they make a solid "thunk" with a hand twist. Different threads and pressures than the 700 action and haven't had one shoot loose yet.
 
Like Guntech says all 700's seem to have loctite on them. I even encountered a rifle where the GS had loctited on the SS barrel to a Barnard action. I think he was trying to prevent any other GS from working on it. He gave no reply when the customer asked why he had done it. He had put the barrel on a repeater but left the edge of the chamber too sharp to feed so I was fixing this problem. I had no trouble removing it loctite or not and perhaps the glue worked a bit as anti seize.
