Recommended Posts

End of season trip to the marsh today which ended in a blank, so time to give the guns a good clean and some tlc before storing for the summer.....the choke in my Lanber sporting upper barrel is stuck fast, and the choke in my Hatsan Escort is as well!!! (Blo*dy typical 2 of my guns!) So before i head to a gunsmith does anybody have any advice of what I can try first??

Many Thanks. Aled

You could try WD40, also tap the outside of the barrel on the choke area with a wooden tool handle - say a file handle or similar. Gently does it. Your just causing vibration, not a proper impact. Also over tighten the choke along with trying to loosen it. I’ve only ever done this once and it worked. If it’s really solid it’s the diesel option. Good luck.

Stand it barrel down in some diesel.and or warm up with hair drier

This. And/or but not with the diesel slopping all over try freezing the barrels and then when WELL frozen plunging the muzzle in boiling water. In theory the difference in expansion should "break" any seal.

Does diesel or petrol strip blueing? 

I'm sure I saw a post on FB the other week off one of the big barrel blueing guys showing a gun that had been stood in something to loosen a stuck choke.

Blueing was totally gone in the submerged part.

I would use diesel.  It has very good creeping qualities, and includes some form of clever lubricant (to protect the tiny high stressed moving parts in the fuel injection items of the engine).

I am also a fan of ATF (automatic transmission fluid) which has evolved to protect a complex highly stressed gearbox over a wide range of temperatures - a job it does well, but I think diesel creeps better, so better in this case.

Both of the above have benefited from long evolution and HUGE research spending to make them really good at protecting complex mechanical items, and are so readily available.

I have used diesel countless times for releasing stuck chokes, it has never damaged the blueing on any of the guns that I have done. I remember a few years back, the same was said about WD40. I have never seen WD damage a guns finish either. It amazes me, the number of stuck chokes that occur on peoples guns. I have NEVER had a stuck choke in my guns, since Winchester started using Winchokes in the 1980's. I do NOT remove them each time I clean the gun either. However, I do put the choke key in, break the choke seal, then retighten it after EVERY clean.

Dont have guns with multi chokes and save yourself a lot of problems . Simple !😁

I wouldn't, but I do have one so fitted by a previous owner.  I grease (or check for grease) them every time I clean the gun (every time it is used) and never had one stick.
