Jim, I wasn't aware they'd changed the HS 28ga shells either, only that Win had changed from the old AA to the new AA-HS. I've had excellent luck reloading them with Longshot and either the Win AA-HS wads or the Claybuster clones. Plenty of crimp depth. However, I can't get the published formula for Unique to work--insufficient case capacity, from what I've found. No real surprise there, since the difference is a #13 MEC bushing with Longshot, #19 with Unique.
