Found this in some hulls while I was reloading
Had some of them. took a special wad. did not dare shoot in a auto or pump. Would sometimes shoot part of case up into the barrel. Happened to me but i was lucky and caught it. Had a 30 gallon drum of them loaded. shot well. I shot in my o/u and checked barrels after every shot. Save them as conversation piece. Doubt could get wads to load them even if you wanted to.Looks sort of like an old Active Hull, but has Eclipse wording on it.
Never seen one before.
