20 Gauge Shotgun Lubed Ox-Yoke Originals Wonder Wads pre-lubed with Wonder Lube 1000 Plus (c). Shotgun Wonder Wads take the place of the over powder card and cushion wad combination, giving a more dense shot pattern and increase range. No need for wet wad loading either. By design, Ox-Yoke Originals Shotgun Wonder Wads have solved the problem of loading through a choked barrel-they have a memory and will return to their original size and shape after passing through the choke. A proper gas seal is maintained and will allow you the full benefits of your load.
