Knight, stuck breach plug

[GEARHEAD]

well i couldnt find anything when searching so posting this. just bought a knight disc extreme, prior to first shoot, i took it apart cleaned everything and pulled and greased the breach plug. got 8 shots thru it, and decided to clean it, before doing more shooting, and found that the breach plug is stuck, i used every tool i could get my hands on at the range, without any success, using the supplied wrench of course too.

Q:  any ideas.

i'm afraid to force the issue, as the season is almost here, i did get it sighted in, and its right on. i'm certain i can get a shot or two or more thru it if i leave it as is, and can remove the nipple.

  Put a small screwdriver through the hole in the tool for leverage.  Mine is always tight after i shoot.  I just snug it, then give a little more when i put mine together.  Be sure to use plenty of the grease.

I only put my nipple and breach plug in hand tight and use gorrilla grease and never have an issue. Use the screw driver and it should come out!

I have had this happen multiple times even though I load the plug up with grease and barely hand tighten it. Especially if I forget to losen it while it is still warm from shooting. The only way I was able to get the plug out was by putting the barrel in a bench vice and using a heavy duty wrench and socket to break it loose. I cut piece of rubber automotive hose the long way and wrap it around the barrell to protect it in the vice.

thanks guys, regarding the tools, yeah they were all levers, i put thru the tool, screw drivers etc, even aided with pliers, got real primal on it. Best idea i got, is like j, said. hate to do it, thinking on waiting till post season maybe. when i replaced it after greasing it,before taking it out today,  i remember thinking, dont put it in to tight, did it by hand, then O.C. got the best of me, and i snugged it, but just a tiny bit. last time i do that. kinda like replacing an oil filter i guess. atleast i got a fouled barrel, and its dead on at 100. so i guess things could be worse.

Dont worry about it. Go hunt. When the seasons over pour a little 30W down the barrel and let it sit in a corner for a month.

[Kowsrule30]

Over tightening could be your issue then the fouling and heat do the rest.... I put my breech in hand tight... the nipple a hair tighter.... And use a quality breech grease... But don't over do it.....

[JimmyHoffa]

Could spray some break free down the barrel for a few days then put a low temp torch to it.  Kind of how I get things off (breech plugs, axle nuts, lugs).

[Natas5150]

That's a tough call on leaving it in until hunting season is over. I would try and get it free sooner. The longer you wait and continue to use the muzzy it may become worse. Try some of the methods of removing it others have told you to get it free. And when you do get it free be very liberal with greasing the breech as well as the nipple, heck I would maybe even go as far as replacing the breech altogether. Worse case and you cant get it out take it to a gunsmith and perhaps they can do it for ya.

I am not sure if you have solved your problem or not at this point.  But that stuck breech plug should not be a real huge problem provided you have the time to work with it.

Suggestions - it sounds like you are using the breech plug tools that Knight provides - I would suggest that you use a 1/4" ratchet, with a long extension and a 7/16" deep socket to install and remove the BP...

The upper left hand picture in this composite shows the setup that I use...



Of course this does not help you get the nipple out - you do have to use a factory tool for that.

But to get the stuck plug out you might try this it has worked for me more than once.  Remove the barreled action from the stock.  Take the bolt out and remove the trigger assembly - one allen head screw... And since you are probably in Washington and do not have a scope on it that helps... Boil a pot of water and when it is boiling set the reciever in the hot water for several minutes, it would even help if you could pour some down the barrel.  After several minutes in the water the reciever should be well heated and with the tools on hand you should be able to remove the plug.  The heat should cause the barrel to expand and allow water to loosen the burnt powder residue and things should once again unscrew.

Make sure you dry everthing real well - re-assemble-clean and you are goo to go.

Hope this mght help...

I had the same thing happen with my Disc Extreme.  I tried everything I could with the givin tools, it just wasnt cutting it.  I soaked it with kroil and WD 40 for a few days, after that I used a 1/4' ratchet with a deep 7/16 socket with a cheater bar attached, set the rifle on the floor to get a little more leverage and it finally came apart.  Good luck!

[GEARHEAD]

thanks again guys...got the extension and socket ready to go, just worried about damaging, and timid about removing the barrel from the stock this close in, as i only have one day to shoot if i get it removed and replaced. i'll gitr done one way or ta other. thanks again. good luck to you all.

btw, only got 9 shots thru it, but i got near 1 inch groups at 50 yards, and placed two shots at 4oclock just one and two inches from a 2inch bullseye at 100.  triple7 ffg 100gr w/ 250 gr spitfires. couldnt experiment, but i believe this should down a deer at 100 i hope.

I take my action out of the stock every time i clean my gun always shoots the same.

[ICEMAN]

Kroil.

I have a Knight Bighorn Mag, and there have been times I thought I'd never get that breech plug out.  I've generally been successful in soaking the plug from both sides with muzzleloader solvent for a few hours, and then using increasing force on the breech plug to get it turning.  I hate to admit this, but I've even used a hammer to tap on the screwdriver that is inserted into the breech plug tool to knock things loose.  I like the suggestions from the other guys on this thread. 

By the way, I'm getting serious deer fever, and looking forward to the opener a week from tomorrow!!!  Good luck to all of you.

I never tighten my bighorn breech plug more then hand tight, but it always gets stuck after I shoot targets. I think it has alot to do with how many shots you take. It never happens when I clean after shootin at a critter. I just take it apart, wrap a rag around the barrel, and put it in the vise in my garage. Like said before, I take my gun completly apart every time I clean. Takin the barrel off the stock has never affected my accuracy. Good luck

I am also a believer that the breech plug should be snug in the barrel... The reason for this is the face of the breech plug should mate up with the shelf in the barrel and create a gas seal at this point.  If you can get the seal here it protects your threads...

This drawing is an attempt to explain what I am saying...



In the drawing you can see I suggest using teflon tape to create the seal both at the two mating surfaces and the threads if the gas should leak by the first seal.  At lot of people use grease to accomplish the same thing and it works for you great.  I just never have like the mess and the tape seems to me easier to use.  BUT... it doestake some practice to apply it correctly.  I would like to say it is 100% effective but even at times I still get a leak once in awhile that results in a very tight plug to start to remove but once moving it turns out easily...

This was one of my first attempts to explain the taping method...



This is the re-dooo, and you can see in this picture set I am using white tape versus the pink tape in the first picture.  Pink is a little thicker tape and seals a bit better but some plugs are to tight to use pink.



If you decide to try this taping method I would suggest that you put a small amount of grease on the outside the tape until you build confidence in the application.

When you remove the plug most of the tape will remain in the BP orfice and you will need a bore brush to pull it out...

[GEARHEAD]

well its out, and the gun is cleaned, so back to the drawing board. placed a 250 pound vise on it, with both feet, and a ratchet with two extentions did the trick. i will keep that ratchet system with me for now on, and im gonna loosen and snug up after every shot. thanks again guys.

I also have a bighorn and i just use silver anti-seize on the nipple and breech plug threads. I have had my bighorn for a bit over a year and have a couple hundred shots downrange and it comes free very easily every single time i am done shooting. The first time i took it out we shot it fifty times and it still was very easy to remove.

[GEARHEAD]

Hmmmm, i like that. thanks.

  ill try that too.

You need to have that breech plug greased and tight to seal all the crap in the barrel and not your threads.  Hand tightening is going to give you a poor seal, and allow all the fouling into your threads.  Sabotloader with the teflon pipe tape is overkill, but you won't get a stuck plug with tape either, and it will clean up easier becasue the tape keeps the threads mostly clean.

Taking an inline muzzleloader off the stock will not affect your zero when you put it back together.  They have full floated barrels, and all the sights, and other parts are essentially 'one piece'.  Its not like you are changing pressure on teh barrel like with a wood stocked rifle that fits snug to the barrel.
