This may start a firestorm, but here goes.....
Make sure when you home-brew up a patch lube, consider whether your cleaner of choice can actually clean the bore down to metal.
I was using the Hoppe's BP lube for a while, and it is SLIPPERY. Easier to load than other choices. Shot well.
I was fanatically cleaning with room temperature water. I'd clean until the patches came out white. Clean, right? Nope.
Occasionally I'd get a very thin black/grey line radiating out on a cleaning patch that wouldn't go away. Puzzling. What that was, was an indicator something wasn't right.
I switched the cheap blue windshield washer fluid at the advice of a good friend, after finding it does clean up faster with less patches. Still, the black line occasionally appeared.
I asked one of our esteemed repositories of knowledge here on ALR for advice. He said it was graphite in the bore. I had never considered that the bore was not completely clean, as the used cleaning patches were white when I was done. He suggested a deep cleaning with Lehigh Valley Lube or Mr Flintlock. I broke out the LVL, and WOW, the patches came out black. Really black. Took a while to get patches to come out white.
What I am getting at is that you can use something for a lube that may get heat ironed into your bore, that your normal cleaner may not be able to remove. Just something to think about when experimenting.
I am using Mr Flintlock now for patch lube. I am cleaning to around 90% with blue washer fluid, then switching to Mr Flinklock to finish. I have no doubt that Mr Flintlock as a lube will be removed by Mr Flintlock as a cleaner. It will also cut graphite. Of course, folks in 1770 didn't have to deal with heavy graphite, so their experience was different than ours. They also freshed out their wrought iron barrels, while we expect a barrel to last a lifetime.
As I said, just something to think about when you are experimenting with patch lubes. "Am I using a cleaner that will actually cut through my heat applied lube?" Look at the contents of Ballistol for instance, and consider what cleaner will pull out those ingredients.
Best wishes, and God Bless, Marc
