My disc extreme is my fourth black powder gun. I have been cleaning the barrel the same as I did in my other ones. I get it good and clean with hot soapy water. Then at the end I hold on to the barrel with one hand with a chopper mitten on and pour boiling water down the barrel with an old coffee pot.Then I put a towel on the floor, and set the barrel against the wall muzzle end up breech end on the towel and let it dry and cool off a bit. Then I put some break-free clp on a patch and oil up the barrel, getting itready for storage.The thing that is different with this new gun is that the patch ends up a little rust colored when I do this, not bad but still a little troubling to me. I have shot and cleaned the gun twice and it has been the same both times.
This never happened with my other muzzleloaders. Can anyone explain why it is happening with this one? It is stainless steel and it seems to flash rust while the blued barrels did not.
Any tips welcome.

Next time before you run the break free down the barrel to get it ready for storage.. take a patch and put some isopropyl alcohol on it. As soon as the boiling water is pored though the barrel swab it with the alcohol patch. That will help dry the barrel right NOW. Then feel free to swab the barrel even while hot with the break free. All that will happen is as the barrel cools it will draw that break free into the pores of the barrel. It actually protects it better.

I am going to guess. When you pour the boiling water through the barrel to heat it and dry it, as you set it in a corner to cool, that is when the flash rust is forming. Run the alcohol through it right away and that should help dry the barrel faster. I personally clean my rifles the same way you described, and never encountered that problem you have there.

Thanks, I will try that next time. Still not sure why it happens with this one and not the others. Another of the many mysteries of life.

It seems like a concern but actually it isn't. As long as you get it out. I clean all my traditionals using the hot sopy water and very hot clean water rinse. Its amazing how quick the surface can rust. After my rinse, I swab the barrel with clean dry patches until this brown coloring doesn't show up on the patch. Then I run some dampened patches of #13 Black powder solvent down the bore and then dry. Final step is a patch with (Don't tell Cayugad) bore butter.

I bought a SSPro Hunter last year and the first time hunting with it was a foggy morning, anywayI left the gun all day thinking it would be fine... when I picked it up it had rust spots all over the frame and barrel [:@]the rust did come off but boy was I upset!
