Stuck Breech Plug
 

I have a Thompson Omega that I cannot get the Breech plug out of. It just wont let loose. Been trying spraying WD 40 on the plug for two days but it just wont loosen. Any suggestions?

There have been numerous methods suggested if you check all the past threads. I have what I think is a new one however. It sort of depends on what you shot last (My guess would be Tripple Seven as it sticks more breechplugs than anything else. I would pour boiling water into the barrel and make sure the barrel is quite hot. Pour out the water and then take a wart removing spray (available at drug stores) usually liquid nitrogen just like the doctor uses. Spray the breechplug with the liquid nitrogen and when it is cool and the barrel is still hot try again. If that does not work you can still remove warts. (hot barrel expands, cold breechplug shrinks)

ML Keith... that's a cleaver idea.

Another way is to plug the breech hole and pour some Kroll Oil down it. Normally that stuff will penetrate anything.

Then there is the boiling water and ice water trick. Get some boiling water in a tea kettle and after you remove the barrel pour that down the barrel through the stuck plug until it is good and hot. Then dunk that breech end into ice water. After about two minutes in the ice bath get that barrel in a vice, put your wrench on it, and tap it gentle like on the wrench part with a hammer or something. I like to have a cross piece as leverage with the wrench. Tap on the cross piece. Normally the plug will let go.

Others do the opposite. They stick the barrel in the freezer over night. Then in the morning, near a vice, with all their tools out, and gloves, pour boiling water down the barrel for a couple barrel fulls and then put that barrel in a vice quickly and get your wrench on it.

Or send it back to Thompson Center.

PA_BOW_HUNTER,If you were to give more info the chances are much greater that we could help you, the type and brand of gun what you shoot in it ,how long it has set while stuck and what you have tried both tools and solvent.
If it is an inline which you normally take the plug out of regular and you shoot 777 in it its one type of problem, in that case it would be wise to includ what type of breach plug grease you used. If this is the case try what
MLKeithsuggested if not give us more info and we will suggest some other things. Lee

I would say if all else fails send it back to t/c shipping is around $10.00 :You pay only one way
and there is no charge.I had a screw on a base mount that just was frozen over the years:I could of drilled it out and retape it myself:I called t/c they said just return the barrel action and they took care of it no charge.

Pull the barrel and put in in a vise and use a propane torch to heat the breech plug area while keeping pressure on the plug with your tool. Thats the easiest way to do it and it actually works.

"Another way is to plug the breech hole and pour some Kroll Oil down it."

Good advice, have used in other folks guns and it worked every time.

Hey Guys, I plugged the breech hole with a toothpick and poured very hot water down the barrel. I didnt want to jam the toothpick in too far - did not want it to break off. Then I poured the hot water down the barrel and let it drip out the breech hole. I did this 3 times and then tried with a 7/16 6 sided socket and was able to get it out.

Thanks for the help!!!!

This is a great idea except for one thing; It won't work! I checked with the local drug store and the wart stuff is not really nitrogen but a mixture of propane and ether and only comes out in small dose amounts with some kind of sponge tip thing. I guess if you could get a full stream of liquid nitrogen out it would be dangerous as you could freeze off your finger, toe etc. Glad he got the plug out without much real effort.

I know a lot of people claim they do not have problems with breech plugs getting stuck, but I am not one of them that can say that. The first day I shot my new Black Diamond XR I stuck that breech plug so tight, I ended up breaking that wonderful wrench (junk) that came with the rifle.

When I got my knew Knight Disc, I was more careful.. and it still had to be put in a vice and twisted out. So the best thing I found is what I call my ten shot rule. After ten shots, I take my wrench and twist that breech plug. Since my rifles are not fancy break open, this gives me time to clean the hammer striker, the breech area, the nipples (all but my disc shoots #11 caps), and gives me a break from pounding lead down range.

I am real glad to hear that you got the breech plug out. I know how frustrating that is.

The important thing now, a really good grease like TC breach plug grease or nickle antisize or slick 50 one greae and be sure before you screw it back in that all the threads on both the barrel and the breach plug are cmpletely clean grese them good and put it back FINGER TIGHT ONLY. Good luck. Lee

So far I have really been fortunate on this subject... with all the different inlines I have owned I have never stuck a breech plug (I am knowcking on wood right now), but, I do go at it in a different method... no grease and tightened snuggly - but not to tight...

It is my belief that you must stop blow-back at the face of the BP and the rear flange in the barrel. if you are able to get this done you need not worry about stuck plugs... I shoot either a 100 or 110 grains of T7 consistently with 209 ignition and it works for me. I just posted my method again in:

for those that might be interested in it... but again it works for me and others but your results might differ....

Sabotloader.. where do you purchase your red breech plug tape? Or is that T/C breech plug tape?

I use both the TC tape and I purchase the pink tape from Lowes or Home Depot... it is a lot less expensive than the TC tape...

One thing i do not think I have in my write-up is - after you have applied the tape to the BP - insert it between your thumb and fingers and with the ratchet turn the plug while applying pressure with you fingers to squeeze the tape down into the threads.... When inserting the bp back into the gun turn the plug slowly as not create any friction heat and cause tearing. It should turn in smoothly to a full stop. Last thing take a light and shine down the barrel verify that you have tape all the way around the end of the barrel.

Over-wrapping the nose is key - pat the excess down on the nose even if it covers the flash hole. Popping one cap takes care of that...

Another thing after seeing a TC blackdiamond BP @ Sportsman Whse - i am not sure this method will work with that particular plug... I wish i could have tried it.

RE: Stuck Breech Plug
 

Well, after reading about it for the last year I finally tried Sabotloader's teflon tape method during my last two range sessions. All I can say is I'LL NEVER GO BACK to grease.

I usedtwo wraps of the yellow tape and had firm, but not tight resistancescrewing in the plug. Also had firm, but not tight resistance taking out the plug. Threads were as clean as when I put it in.Thanks Sabotloader!

The two greatest improvement in my "in-line" life - .25 ACP breech plug & teflon tape.

RE: Stuck Breech Plug
 

I have never stuck one myself but have unstuck a number of them for other people, most of them admited to cranking them down with a wrench, but I do believe that greasing them like the directions say isnot abad idea,as well as keeping them from corrosion in long term storage it keeps them from sticking if those machined faces dont exactly match. One of the things I have noticed is if some one once cranks them down to hard and it slightly gauls the machined faces they tend to not only blow back more but to keep right on sticking. I have blacked and fited and polished mine so I also have reduced the blow back into the threads, the only one I did not do this on is the Triumph it did not need it.
I tried the tape and it worked ok,I guess I just like messing around with them.Lee
