Hoppes #9 for copper fouling?

[king4wd]

Plug the chamber with a rubber cork and fill the barrel with Hoppes #9 and let sit for a few days. It clears out the fouling but is it damaging my gun? It seems a lot less corrosive than most copper solvents.

I don't think Hoppes #9 is effective for copper. My use of Hoppes #9 is restricted to shotguns and quick cleaning on the range. I also use Shooter's Choice for cleaning on the range after 15 or 20 rounds, and for handguns. For giving a gun a good thorough cleaning, I use either Barnes CR-10 or Sweets. Both work on copper. Hoppes also makes a copper solvent just for copper. I'd guess using Hoppes #9 and their copper solvent afterward would probably work just fine.

Try "Iooso".

Hoppes 9 is for carbon fouling.

Which Hoppes 9 product? http://www.hoppes.com/

 

The regular Hoppes #9 Solvent that smells good is for powder fouling and good before using a copper remover.

Hoppes 9 Benchrest Copper Remover might be what you are talking about and they say is safe to leave in the bore overnight as it is not ammonia based. http://www.hoppes.com/products/bench_rest9.html

 

Montana Extreme 50BMG is good stuff.
