I hope you will listen to hm, he is shooting straight on this cleaning issue!
Wipe out is great on copper, but it does not touch carbon unless you use it with the brush, the brush is doing the work.
If you do not like using good bronze bristle brushes, then Isso and Montana Extreme make very, very good plastic brushes.
I have a bore scope, dealing with cooked on carbon is no fun to say the least.
I have been using a product called Bore tec C4, it is a very decent product.
If you have to get carbon out and copper out, RIGHT NOW, then Montana Extreme Copper Killer will get the job done with a good plastic brush.
If you have let carbon build up in your barrel, there are a couple of things that work:
Montana Extreme Copper cream on a brush
JB on a brush
JB saturated on 5 patches, short stroking
ISSO used on patches or brush
If the above does not work, then wrapping some 0000 steel wool on a brush and using JB or Isso for 20 strokes.
If the above does not work, Brownells sells a 600 & 800 grit aluminum Oxide paste, try brushing with this, For comparrison, JB is around 1200 grit.
If your barrel is still has a boat load of carbon, then Brownell's sells a 600 & 800 grit of Silicone Carbide paste, use it on a brush or patches...this is the last resort.
Years ago, I had a 22/250 barrel that had seen 600 rounds shot red hot on Jackrabbits. The barrel got to where it would only shoot around 2" groups. An old gunsmith in San Leandro, Ca recommended to me that I use a good brush with Lava Soap. The barrel went back to shooting again, but I had shot the leade out and had to shoot 63g Sierra's to get it to shoot. I got another 800 rounds out of the barrel after the lava soap treatment.
