DO NOT use the mink oil for your boots. It has some stuff in it that is not good on the bore. Get the stuff from TOTW. That is what I have
Another one is Lehigh Valley. I really like that for at the range. And yes, Sno-Seal should work.
TOTW has Lehigh Valley and Mink Oil. Mink Oil is good in Cold Weather. I like Lehigh better at the range than for hunting. Try some of each.
