What is a good solvent to clean copper fouling? I was going to try the blue wonder but it seems to be on back order everwhere.

butch's bore shine

I hear the Barnes Copper remover is pretty good.

I love Sweets 7.62

That's a pretty good line-up right there.

I have used em all. RR set you right. But I love Wipe Out.

I'm a benchrest long range competitor and get a chance to see alot of guys in action cleaning just about everything made on the planet and the one product that I see used only when alot of fouling is showing is called "TM"..and also "GM" top engine cleaner..... now remember these are not standard of the shelf barrels and most of these guys baby them beyond anything that a hunting barrel would ever see in a lifetime, I can tell you that "TM" is awesome but make sure you wear gloves, it will remove your top layer of skin also....

I use shooters choice and montana extreme for copper removal, for powder residue it's eau de hoppe's #9

I use wipe-out followed by Butch's for general cleaning. Every 2-3 cleanings I'll plug the barrel and soak it in Barnes CR-10 for 20 minutes, it strips copper very well. But wear gloves and keep it out of your action, it's not mild stuff.

KG-12, unbeleivable stuff. I used to use Sweets until I tried this stuff. There is no comparrison. Much Faster, can't really say cleaner because sweets does a great job, but KG-12 is a lot faster.
