GoJo??? That's a new one on me. Why and how did you come up with that? I have been using Bore Butter with good results. I tried pure mutton tallow but had problems with fouling after just a couple shots. I always wanted to try "moose milk" (water and water soluble machinist oil) but just never got around to making any. It's supposed to make a great cleaner and lube that will clean the bore each time you load. Has anyone here ever used it? Been meaning to make some for the last 35 years or so.
