I would check for a local sporting clays group and inquire about where the shooters in that group get their hulls. The 28 ga has gotten quite a resurgence as a more "gentlemanly" gun. They handle beautifully and perform as well as a 20 ga with less recoil. If you are willing to drive a bit, check with Hot Wells shooting range in Cypress. The owner, Gary Lamar, was a world class .410 skeet shooter when we were in high school together.
