A couple of months ago I posted about a Sako 338 that was masquerading as a copper mine each time I shot it. Applying DBC, I followed MD's instructions to the T and it showed marked improvement. However, it took three separate applications of DBC for it to "take".
Now, when I shoot, it still copper fouls, just not as much....pretty much what I'd consider "average" for a rifle, which is a great improvement. However, the biggest plus is now cleanup is a snap, using Wipeout, rather than a long drawn out two day affair.
Good luck with your project. I'd look at a second DBC application if I were you.
