I make my own, Stump's Moose Snot...If you don't want to make your own, try SnoSeal, I used that for about 25 years or so before I tried this stuff out...

There have been many lubes that I've heard of through the years from Crisco to vasoline, bear grease, deer fat, groundhog fat, olive oil, balistol, even axle grease...Try several and see what your gun likes...The main thing with shooting patched balls is to look at the patches after the shot and see what they look like...If they are burning through you need a thicker patch, larger diameter ball or a better lube...
