Honestly if you’re a clay target shooter it pays to reload shotgun shells. If you only plan on reloading a few hunting loads it cost enough to get set up I’m not sure it’s worth it. Ballistic Products carry more hunting type components that you would be looking for. Availability of primers and shotgun powder is horrible right now. The proper wad is one of the key components in your shotgun shells because of its effect on patterns and stack height. Definitely need a good reloading manual from the powder manufacturer or Lyman. As far as hulls, you can find standard size hulls (2 3/4”) at your local gun club. Hunting size like 3” or 3 1/2” are going to be harder to find. Turkey loads aren’t that expensive in this component crisis that we are in right now. Good luck man.
