If you use Ox-yoke Wonder Seals, do you put them on top of the revolver charge and under the ball, or do you seat the ball on top of the powder and then put in a wonder seal? I have some seals that I haven't tried yet. The instructions on the container show powder, wonder wad, ball then a wonder seal. I thought I read somewhere that all that is necessary is a wonder seal between the powder amd ball to prevent cross fires. Thanks for the help!
