I have only used mink oil by itself, but the addition as Mike noted, of neetsfoot oil might render it more liquid in colder temperatures.
As noted, I have only used it by itself, since the mid 1980's in the .69 for hunting in -40 and colder, weather. I heat the tin over a hot
plate and when liquid, I pour it over pre-cut patches, then when almost cool, I squeeze out the excess and pour that back in to the tin.
I realize it is dangerous to heat the tin of mink oil on a hot plate, but I watch it and when melted it is taken off, without spilling ANY on the hot plate.
I find the 2nd shot through 50th or 60th loaded easier than the first one when trying it in my .32. No swabbing nor wiping the bore was necessary
nor is it ever. That is no different than any other of my rifles, including the smoothbore, when shooting patched balls.
