I used to use the original Lehigh Valley lube for a patch lube and loved it. When I ran out I searched around and tried various combos of lubes. I use Hoppes Black Powder Cleaner and Lube for a while now for a patch lube. As roundball said, wet the patches with it and shoot all day with no wiping, and the last shot loads as easy as the first. After shooting I take a clean patch soaked with the lube and wipe the barrel and the patch comes out gray, not black.
