I've heard some real horror stories about this..
My advice is to take it to a Smith.. He probably can't do anything that you can, but if ya leave it with him you won't have to watch the carnage...
I've never owned a bore-snake and don't plan to...
Never have understood why folks would never even consider using the same patch twice, yet they'll run that filthy thing through a barrel and never think twice about it..
Oh yea,,, I forgot,,, ya can put it in the washing machine...
Good Luck
