I prefer mink oil when hunting, but have been experimenting with other things. I started out with Crisco!
As of late, I'm trying olive oil, palm oil, and combinations of those mixed with each other and/or mink oil. I have water soluable oil and want to revisit that at some point in time.
I've used Lehigh Valley Lube (byproduct of pulp wood industry) which, IIRC, is now Shenandoah Valley Lube, Hoppes #9+, Bore Butter, Natural Lube 1000.
Lots of things work, but may require a bit of load adjustment. My preference is to NOT put anything into the barrel that will freeze or dry out, so is why I'm experimenting. Too, I prefer to shhot without wiping between shots, so prefer lubes that combine with fouling to keep it soft.
