Not having and marmot oil, bear, deer, caribou or moose tallow, I use Neetsfoot oil or Tracks Mink oil.
Guess now I'll try Mineral Oil, but then I don't hunt anymore. Guess I should try it just to see how it works, for this forum's sake. Might be good afterall.
I'm thinking canola oil might be too far synthesized to work, but then only way to find out, is to try it.
Heading home today for a few. Might get out shooting, if not too hot.
