New to this Forum! Hoping someone can help me learn more about this cartridge case - it would seem they aren’t very common. I am trying to sell items that belonged to Ken Howell, the author of “Designing and Forming Custom Cartridges for Rifles and Handguns”. In his large collection are 10 boxes of Winchester Western 9mm Win Mag cartridge cases. They appear to be new. Is there a market for these? My limited research indicates that they were developed for the Wildey in the late 1970's? Thanks in advance - Mark
