As has been mentioned, shotgun hulls do not get cleaned like metallic brass.
Also, unlike metallic brass, you do not mix hull brands. There are specific recipes that I strongly suggest you follow closely. While subbing clone wads of OEM wads is safe and OK, until you get more experienced, do not go subbing other components. You also do not "work up a load" like metallic. If the recipe calls for 17.3 grains, you try to drop as close to that as possible. You don't start at 16.7, 16.9., 17.1, etc....
Larger shot sizes, especially buckshot need to be stacked properly
The powder maker websites like Hodgdon and Alliant have excellent up-to-date data
