I buy my reloading supplies by piggy backing on my gun club's clay bird orders. They buy from a regional distributer who trucks the order directly to the club. Club members can buy powder, primers, wads, shot, reloading machines, loaded ammo at dealer prices and have it delivered to the club without shipping and hazard fees. Don't generally buy hulls as there are lots for the effort of picking them up on the Trap & Skeet ranges. Typical prices are bag of shot - $12.50, wads - $5.50/500, primers $95/5K, 12 ga shells - $30/case (250). Joining a club makes sense!
