Wet fiber wads are typically used in muzzleloaders shooting clays. Soaked in a liquid cleaning solution and squeezed out on loading. The loads are shot right away so no problem contaminating the powder charge. Not used in shot shells where they are not used right away. I use lubed wads in my black powder loads and they work very well keeping the fouling soft and lubing the bores. Lubed wads keep the fiber dust from blowing back into the shooters face. I also use OE powder as it is as fast as Swiss and the fouling is a little lighter and softer. Easily run 50 + loads on the clays course and do not have to punch the tubes in the course of shooting a round. 1fg. in the 10 gauge and 1.5 or 2 fg. in 12,16 and 20's. Work great and hit hard on the course and in the field.
