I use Shooter's Choice Copper Remover...not every cleaning session, though, and I never let it sit in the barrel longer than 10 minutes.

Every third or fourth session (I clean after each day at the range) then immediately clean with a less aggressive cleaner and lube (FP-10, BreakFree, etc...)

You can also use Sweets 7.62 Solvent for copper fouling.

I recently picked up a Pre War Winchester 70 in .30-06 which looked as if it was never cleaned- there was a coppermine in the barrel...

I plugged the chamber and dripped the solvent in the barrel, sloshed it around with an old .22 brush, and let it sit for the recommended max time...

I swabbed it out and it looked like a blue ink pen exploded in the bore! I had to do this several times before it was clean. Then I had to attack the lead.

Use a nylon brush when dealing with copper solvents.

I also use Sweets 7.62. Works like a charm. Make sure you are in a well ventilated area though as the fumes are quite strong.

I use Butch's Bore Shine for copper removal. It works great for removal of lead, powder and gets the barrel shiny clean. Its expensive so I only use it when I see the copper streaks. It won't hurt the barrel if you leave it too long like most copper solvents. I soak the barrels for 30 minutes and then brush and run patches.
