Another thought

I removed the drum from a CVA Hawken barrel because I plan to convert it to flint. The drum broke loose pretty easy and screwed right out. The entire outside of the drum threads are wet. The CLP I am using has penetrated into those threads inside the CVA breech. The protection is wonderful, but I wonder how much the CLP seeping back out of those areas into the dry powder column effects things. Is there enough there to cause a misfire after being loaded for a few hours? Is there enough there to cause a bad hangfire?
Using the CVA breech system, I would have to recommend not using anything that can penetrate into those areas and then leach back out into the powder. If I can get the plug out, I plan to go to another type of breechplug.

I would think that if you heated it up slowly with a torch, it would burn off.

I take it you soaked her for a while to loosen the drum? Once you've cleaned and reassembled it, there shouldn't be too much left. I should think that, after a couple of sessions, the excess should be gone.

Will those take a different drum? I was thinking about a CVA a long time back and remember thinking they had a unique drum/breech plug set up..

I did not soak it at all. It was just as it was left last time I cleaned it. That is why I was shocked to see that the CLP had penetrated around the drum threads.
The drum threads are long enough to cross the barrel and there is a stud on the end that is designed to fit a recess machined in the other side of the barrel. The drum acts like a cross pin to lock the breech in place. Then about a 22 caliber hole is drilled in the drum down the barrel it appears, since the hole in the drum lines up with the hole in the breechplug that is the same size. There is plenty of metal to open the channel more. Actually, if you saw this set up, you would wonder how it ever fired properly. A little coning and enlarging the channel would make a big difference in how these guns shoot.
There is enough metal that I could drill and tap the existing drum for a touch hole liner and put it back in. That would not fix the other problems tho.

Clean your gun as usual load a blank load in it leave it a couple of days and pull the load. You should be able to see if the lubricant effected the powder.
