If I were you, I would not let not having the wads keep me from shooting that White of yours. In my opinion the wads are most necessary if shooting triple 7 or pretty hot loads of another powder. If you are using black powder or pyrodex and using 70 to 80 grains I don't think you will get a lot of leading without the wads if the conicals are properly lubed.
Just my thoughts, I have shot a lot without the wads and haven't had problems with it. I have also used cornmeal like Dave mentioned.
