I have lubed many fiber wads for m-loaders and shells. If I am shooting a round of clays with a m-l I lube when I load, with dawn and water or crisco oil. Don't soak the wads as the lube soaks in and makes the wad heavy and it becomes a slug which blows your patterns. For hunting with m-l and loading shells, I use a 50/50 mix of beeswax and crisco and dip the wads in while it is melted. The thick lube tends to stay on the outside of the wad where it is needed. If it is soaking in too much refrigerate the wads before dipping. ;;;LK
