I see you are using triple 7 as your powder. For the last couple of years I have been using 90% alchohol for dampening the patches that I use to swab between shots. I guess my aim is not to clean the bore completely, but to get rid of most of the residue and make loading the next shot easier. I use the damp alchohol swab when shooting triple 7, pyrodex, and Goex and it does the job fine.
Actually a spit patch would work fine too but I like the way the alchohol dries so quickly so I use that.
If the go jo works good for you that is great, I just think it might be a little more than you really need for swabbing the bore.
