I have never really noticed a big difference in any of the bore cleaning products. I bought a bunch of Butch's once for a good price, so I just use that. However I would never use a brush in my barrels. I simply use a jag and properly sized patches. IMO the jag does a better job, but even if it didn't I would not put a brush in the bore of my rifle. Unless I wanted an abrasive in there. Tom.
