I just came across some Remington wads, about 5k of them. The bag says they are Power Piston, 12GA Target, 1-1/8 oz, #RPA12-W23694. Anyone know what hull these wads were designed for? They have a full length 1-1/8 oz, shot cup but the overall length is about 1/4" shorter than any other wad I have. Were they designed for use with a card or for a hull that had a very high base wad? Any ideas? JRM
