There is a discussion over on benchrest.com about barrel abrasion caused by graphite cleaning rods.
I haven't used mine in a couple of years. I felt they were inherently abrasive and ran a test. Using the end of the rod nearest the handle I used the rod in a saw-like fashion, rubbing it with some pressure across a piece of tool steel. After just 10 such strokes about 8" in length I saw a small groove being worn into the steel, along with some graphite dust.
Those who have a graphite rod might want to take care to avoid letting the rod drop onto the bore when the cleaning patch exits the muzzle. The effect may be minimal, but after a number of cleaning sessions......? Certainly not the prescription for my target rifles.
