| Just wondering. Are there any other JB Bore Cleaner users on this board? |
|
I use it for a 264 Win mag that likes to leave copper in the barrel. This along with alternating cleanings (ie no mixing) with Kroil and then Shooters choice (or Sweets if the copper is really bad) works well.
For 99.9% of "AR" applications, most likely not needed. |

I use USP paste and Kroil. The combination will remove fouling that NH3 solvents leave behind - particularly that lumpy black stuff.
One of my 11.5s became a 12 MOA bullet-tumbling blaster (well, its had nothing but mag dumps X over 6k rounds). But after the paste treatment its shooting as well as ever. Fouls quickly, though. I imagine the barrel is shot out - throat is pretty rude for the first 3+ inches. The abrasives are like life-support. Whether a barrel is worth the extra effort can be debated. Sam |
| I've used it to really scrub out some M1's I got from CMP. Just have to be careful you don't clog up any gas vents / orifices when using it on a gas operated system. It did a nice job. I'd imagine using tooth paste or Soft Scrub would work just as well at a much cheaper price. |

Is it true that this stuff can damage of scratch a bore? It is said the abrasive is softer than steel, but some sources say it is to aggressive. Used properly, no. The benchrest shooters favor Kroil/paste over NH3+ solvents. If accuracy life were negatively impacted by USP or JB paste they would know. If anything, they worry more about etching from prolonged exposure to high-NH3+ cleaners (why I use standard #9, mostly). I use plain old Hoppes #9 for most cleaning. If I go to a shoot and run 1000+ rds through a barrel in a coupla days its going to have alot of caked-on carbon that will not respond to non-abrasive chemistry, IME. You can't believe how much black crap comes out with Kroil/paste after you think you've cleaned it with NH3+ based solvents. Sam |
