I hope you have a lot of patches. The stuff TC uses is hard to get out. I just cleaned out the factory bore oil from a CVA, and used about 15 patches. In my Omega I used about 50 to start with, but the oil kept coming back after I shot it. It's like it gets into the metal and comes out when it feels like it.

I used brake cleaner and every kind of solvent you can think of. I wish i could give you one thing that works the best, but I never found one.

As for cleaning out BH after you shoot it. Use whatever works for CF guns. All of it will work. Don't use any black powder cleaners to clean BH. It won't work.
