So I am at the range the other day, and a guy I am talking while cleaning proceeds to pull a drill out of his range bag. I watch him chock up a cleaning rod section with a copper brush on it followed by spraying the brush with cleaning solution. He then proceeds to "drill" the brush back & forth through the bore. The stuff that came out of the barrel was impressive, and I took a look and it was like polished glass when he was done.
He then proceeds to tell me he uses brake cleaner to do a lot of cleaning tasks, as long as it doesn't touch stock materials (wood/plastic/resin/etc.).
This is on a pistol by the way.
So, is this a fast way to fuck up a gun, or is there any merit to this? The drill was the most intriguing part, as it took him about 30 seconds to get a spotless barrel.
