How Do I Tighten Barrel On A Martini 22? I Need Advice

[albayo]

I have a nice Martini 22 but the barrel is loose.

I think a former owner did not take the gun apart for a considerable time and the the threads may have had some corrosion on them.

They were cleaned up and they made the barrel loose.

Now the barrel moves very little left and right just enough to screw up its accuracy.


I need some advice from you as to what I should do to remedy the problem.

One guy told me to put Locktite on the threads, another said put Teflon tape on the threads and screw the barrel on.

If you never want to take it apart again something like Loctite 609 will keep it in place very permanently. I have a Shilen barrel bonded into a Savage Mk.I receiver with it that is dead solid a decade later and that is just a slip fit, no threads at all.

I’ve read that with takedown greener martinis like the GP shotgun it is not recommended that you remove the barrel off and on a lot because it will loosen up the threads

 

[guntech]

You can 'chase' the barrel threads with a special ground large concave 'punch'... do it towards the muzzle thus tightening the thread slightly, then don't take it off and on a lot.

I used valve grinding compound on my Savage 99 takedown. It’s just enough to tighten up the slack. I don’t take it apart anymore as I probably would accelerate wear even more with the compound in there but it’s really nice and tight now.

Thanks for the advice gentlemen.
The previous owner didn't consider that taking the gun apart would loosen the barrel.
I have had the gun for probably 20 years and shot it a couple of times.

Am presuming that the gun is NOT one of the takedown models using a tapered pin to lock the barrel in?

Personally, I would try the teflon tape first. It's cheap, usually lots around the house, and it has zero detrimental risk for trying to see if it works.

Normal, removable Locktite would be my second choice. Also pretty low risk, and makes no permanent changes to anything.

Worth noting that if you were to distort the threads to make for a tighter fit, you can expect that fit to wear considerably faster, when removing the barrel in future.

depending how loose the fit is you could peen the front of the action with a small punch under the lip of the barrel shoulder.
this will give the barrel areas to bind on taking up the slop in the thread. if you need more than this you could use a thin shim (crush washer)
as the British did with some of the No 4 and l42 rifles.

 

[albayo]

I do have shim stock and try to tighten it up with that.
The barrel moves just a little and some of the above remedies are reasonable and the semi permanent ones are a must.
