Hey Dutch, Thank you for starting this thread. The topic is on my mind because I finally finished the Moose Milk my buddy gave me when I bought my first flinter nine years ago. That means I need to brew up some more. I've used MOS to clean the stock an my antique double rifle, and it's an ingredient in many lube recipes I have seen, but I never thought about using it to clean the bore. I've always used some variant of Simple Orange. Now I'll have to try MOS to clean the bore. And apparently I was right to wonder whether I really needed any other ingredients in the lube when I'm on the range (thanks Cositrike). Usually the snow's on the ground (like now) when I'm hunting, so I use that Trapper's Pure Mink Oil goo from TOTW for that pursuit.
