I tried the alcohol patch method to clean the oil and moisture from the barrel before loading to avoid having to fire a couple primers before loading, then having to unload and clean it after the hunt. Well it's been about three days and not a shot to be had, so with no oil in the barrel I was getting nervous about rust and thought I better unload and swab the bore with a little oil and see how the patch comes out. As I said, I'll never do that again. I used about 20 patches before they stopped coming out BROWN. I've never seen a BROWN patch come out of ANY of my guns, Black Powder or any other.
