Well I don't know what has happened to the Diana shells, but I am no longer on the Diana band wagon. For the past two years they have been the majority of what I have shot (10 cases a year) and never had a bad one. Well I just bought 10 more cases and random boxes out of different cases have left me unhappy. Probably 3 or 4 shells of every box has been a puffer. I have to check the barrel to make sure the wad comes out. People think I'm shooting reloads. If this is what they have come to I am off the band wagon.
