I don't post much here but I like how this subject got resurrected and I thought I'd note that I have used Hoppes 9 and Kroll oil at a 50/50 mix as a bore cleaner for probably 10 years. I also use this mix to clean up the crud around the ejector area of most of the semi-auto pistols I own, then CLP or Rem-oil.
Breakfree CLP is used on most of my trap guns for cleaning crud along with my 50/50 bore mix but my lube on them is the same one I use for my M1 Garands "Plastilube".
As a side note: Do you know how to tell when you have an inexperienced gun guy at a "Big Box" sporting good store?
When you ask them where they have the Breakfree and they suggest you must go to an Autoparts store!!!!!
Happened to me at a Gander Mt store here.
