On the range I have used spit as a lube for the patch and ball. Even dish water soap. All of them worked good. Have swabbed the bore with the same. At one Rendezvous shoot there was a team that stood there with patch material hanging out of their mouth. That was their patch lube and swab material. They did real good with it too.

I still like moose milk. Cheap to make and works good in my rifles. As for dimples on the ball ... well I never heard of it or tried it.
