Re: Gun oil??
Breakfree CLP is what the US Army was, and maybe still is, using.
"CLP" stands for Cleans, Lubricates, Protects.
However, I would recommend running a patch of Hoppes #9 powder solvent just prior to fouling shots as it helps make the cold bore shot fall into the group. If your interested in that kind of stuff.
Personally, I like "Tetra Gun" oil, even tho it stinks to high heaven.
It works great when fresh, but tends to gum after about a year.
