Thanks, but it's what I have on hand, besides neatsfoot oil. I've researched both for several hours and found a good sampling of users. And both give 50% saying it's great, and 50% saying it's terrible. I know things like cleaning methods and patch lube are very subjective and personal. So I'll have to just see what works for me. I know I don't want to be beholden to some store bought product, that can run out, or stores can close, and so on.
I do use SPG for my BP Cartridge rifle loads. I guess that's a 3rd thing I have on hand, til it runs out. From it's smell, I guess SPG has beeswax in it too. Not sure of the oil. But I also have olive oil on hand...
May try coconut oil at some point...when the stores are safe to return to.
