Does anyone know a cleaning solution that i can soak my breech plug for my muzzleloader in. I got some fouling marks on it that i just cannot get off.

I bought a old M/L last year and just got around to trying to get the breechplug out. The guy I bought it off of stored it for about 3 years in a old bus and the breechplug is basicly welded in. Or at least in might as well be. I'm soaking it in 1/2 acetone and 1/2 automatic transmission fluid. Its been in for 2 whole days and I tried it about a hour ago and it won't budge. I just ordered some Kroil off of Brownells. Maybe it'll work.

Good luck, mine is basically welded in. Ordered kroil....not help!!!

Just bought a Knight, quickly fixed my problem!
 
ROVERBOY go to an auto parts store and get you some PB spray. Spray some around the threads where the primer goes on the breech plug, and then spray some down the barrel and stand the gun straight up to let the PB enter the threads. Let it sit for 30 mins. if you have a rubber mallet or something soft tap on the barrel where the threads are. Spray some more let it set and give it another tap. Then try to break it lose. This stuff has worked wonders for me when i couldn't break things lose. My brother swears by it. Said he was trying to get his wife's brake rotor off and was literally hitting them with a sledge hammer and they wouldn't budge. Sprayed this stuff on there and let it set and the rotor slid right off.
 
Thanks, Travle. I'll try and pick some up tomorrow and see how it does. I've got the Kroil on the way but, if the PB works thats great. I can use the Kroil on something else.

I recently took one out of a Knight LK93 that had sat for two years uncleaned. I poured Kroll down the barrel and after one day it wouldn't budge, BUT on day two, came right out. I did take a screwdriver and pop the end of the BP a couple times and I think that helped.

When I got the BP out you could see where the Kroll had penetrated down the threads. Kroll will work, it just takes a day or two for it to get into the threads.

Good luck!

Always heard that stuff was amazing.

And it's a Tennessee product; made in Nashville.
 
As long as this topic is up I have a question. First of all I can't understand why someone would put ther muzzleloader away for the season before cleaning it. That being said I always clean mine up good before I put it away. Still, my breech plug wants to "freeze" in the barrel. Would it be better when storing the rifle away to leave the breech plug out of it?
 
Mine has just built up fouling marks from the powered and primer that regular gun oil wouldn't take off.

Mike Belt every time i clean mine i put anti seize on the breech plug. i stored mine for 2 years because i couldnt hunt last year. and it broke free with no problems.

Yep, I always coat the threads of my breach plug with "anti seize" every time I clean it. Never had a problem with it not coming out easily.
Anti Seize has a graphite looking solution on it that doesn't dry out. Good stuff!!!
 
Try Thompson Center breech plug cleaner solvent & container, part #7433. It has a little basket in it, put breech plug in, shake and let sit for a minute or two. Problem solved.

I've stored mine with the breech plug out for the last couple of years. I had to clean the barrel as hard the next season as I did before I stored the gun. I think the extra ventilation allows more rust to build up. I always use breech plug grease, so I think this year I'm just going to clean and store with the breech plug lubed up.
 
When season is over after regular cleaning I swab the barrel with Rem oil, I've also tried motor oil synthetic and natural. Then I stuff cotton balls about 5 deep on each end. I do not re-assemble the weapon until next time I use it. I store the barrel flat-not vertical.
 
I actually store my ML, after cleaning, barrel down and on a rag to absorb any oil that will drain down. I do this to keep that remnant oil from draining into the breech plug.

x2, same here. Some people shooting the Savages are using teflon tape in place of anti-seize on the breech plug. I have yet to try this approach, only read about it thus far. See this thread for more information about the teflon tape approach. http://dougsmessageboards.proboards.com ... e=1#113452

Interesting read. And yes Anti Seize is messy as all get out and leaves finger prints everywhere if ya don't wash it off your hands ASAP.
Looks like the teflon tape is a good idea. A lot easier to just smear a little anti seize on there for me though.
