I used some of them in ancient Reliance 'Red Head' and Winchester 'Ranger' paper 12 ga. hulls this past summer in some skeet events, purely for the fun of it. They still work just fine, and saved me the trouble of having to find a one piece wad that would give me the exact required stack height for a good crimp. I actually had three different base wad heights in an assortment of old paper hulls. In some ways, I wish they were still available. It was fun telling some of the shooters that the hulls I was using were older than they were and some of the trap kids kept some of those empties, just because. I have enough of those Lage Uniwads left for perhaps another few boxes of 12 ga 28 gram cartridges. I wouldn't mind having more of them.
