Decided to try it. Ran a patch through the bore of one of my .270s and was surprised to see a bright greenish-blue residue on the patch. That's the copper fouling being wiped clean. Didn't realize that Frog Lube removes copper. Did it very easily at that. Don't think I would use it on the action, prefer a good oil or light grease for that. But I like the light film it leaves on the finish, would think that's a plus for long-term storage.
Any thoughts?
