I've settled on fiber wads from TOTW. I break the 1" wad in half before loading, and often use an over-powder wad, when I remember to bring them. Otherwise, it's just more stuff to carry around, and results are good either way.
Measure and dump your powder, seat the 1/2" fiber wad, then use a dry lubed brown paper strip (about 1" x 3" depending on your shot load). I form the strip around a .308 brass cartridge by placing the brass base in the center of the paper strip, then simply forming the ends upward around it - just center the strip over the muzzle and push till both ends are just below flush, pour your shot load, use either over-shot card or the other half of the fiber wad, and firmly seat. Some have posted about crumpling up brown paper bag paper to soften it up to make loading easier. I tried it & it works, but it's just one more step in loading. If you have enough of a morning coffee caffine buzz, you may want to crumple up all your paper in advance ... just to take off the edge.
I use a blend of 1:5 castor oil:denatured alcohol for wad lube and also paper lube. The DA evaporates to leave a fine film of castor oil that keeps the bore cleaner longer than anything I've ever used before. In my several decades of BP shooting, no other lube materials even approach the clean shooting properties of castor oil.
