I use the Remington bore cleaner. It is a gray color and a gritty feel. The label says it has abrasives. I like it bacause it cuts through the copper fouling on all my rifles. It takes 20-40 strokes. I follow with some Hoppes (or whatever) to clean out the grit and then oil the bore with Ballistol.
I have been using the same bottle for years because it takes so little and works quick. These are hunting rifles so the most they have through them is 300-500 rounds for practice. Do they still make the stuff? Am I doing any damage?

Remington bought that patent from A company called,,,,Doh,I forget,,blue ribbon? Now if the bore is that fouled enough to demand abrasives,,I use jb bore paste.I know the product you're speaking of,,and it is gritty,,I think jb might be a little easier on the bore. Break free makes a bore cleaner that's ammonia free and seems to get under fouling and lift it out It's at it's best on lead and plastic,,does my shotgun bores in a couple strokes,,It seems to need to digest copper.The trick is to let it do it's thing,,swab it down good,,go have dinner,,then come back to it,,Clay

"Gold Ribbon".

Thank you for keeping me straight there geekay!!! I knew it was something ribbon,,,Clay

I would lose the Remington bore cleaner. It is very abrasive and can embed in your bore. If you must use an abrasive, use JB Bore paste which is non-embedding. My recommendation is to use an aggressive solvent over abrasives. Abrasives are just that...
