I don't see anything on the can about eating copper, maybe I missed that part but I have been using Ballistol for years to clean the carbon / powder residue from the necks of brass cases. Also the neck area of my chamber to remove carbon. I have not ever seen any sign of it stripping copper out of brass, wipe a clean copper item with it and see if there is any colour change.
There is a mention on the Ballistol Web Site FAQ about scratched nickel surfaces and removing the residue. Don't see anything about it eating any metals though.
If you are that worried then switch to something else, like "Inox". It even comes in "Food Grade" for cleaning your Pots n Pans.
I wipe my firearms and stocks with a Ballistol, Inox or Tetra Gun Lube slightly soaked cotton rag and have never had any problems. One thing I will not use is "Remoil".
