For black powder (real black powder) I use the following.
I use a .030 over powder wad, .125 SPG lube, .060 wad beneath bullet.
(the .060 top wad prevents the lube cookie from being hammered into the cupped base of the bullet)
I have shot up to 40 consecutive rounds without wiping or hard fouling.
The last thing I want is a sticky or soaked patch. If its sticky it wont leave the bullet and dirt sticks to it which does the bore no good. If the patch is soaked it looses its strength like wet toilet paper.
If I can wipe between shots then no lube at all.
