The one thing we all seem to have in common, we are all in favor of clean barrels. For this I salute all of you.
I don't use nylon because it makes no difference to the cleaning time or can I see a difference with or without the brush. With a bronze brush I have observed that the brush dissolved with the bore cleaner.
The big thing I have found with the KG-1 and the KG-12 is, I can go back after the initial cleaning weeks later and get nothing else out of the bore. I do not have to kill with alcohol upon completion of cleaning. I buy and use the bulk pack of patches from Brownells. I think they do a fine job of fitting the bore using a jag. I know that cleaning the cleaning rod after each pass makes a lot of difference.
I went through the GM upper engine cleaner to the tune of a gallon. I made Ed's red I have gone through the Montana Extreme, Butches Bore shine. For me the thing that has worked is the KG- products.
Yes I keep the KG products in the highest regard. I don't own but what is in the bottles. No stock in the company. Just happy to share my results. Is this the only thing that works? It is the only thing that allows me to get a clean barrel in fifteen minutes.
