I managed to get a case of them a couple years ago. Good shells for ducks over decoys, but don't pattern as tight as their plastic shot cup loads. I got patterns in the 68-70% range with them in my Super Fox, and LC Smith 3E pigeon gun.

Craig, to follow up on your original post (and for anyone else looking for a lower pressure modern shell) Boss is releasing these new warchief shells with the attached specs. Looks like a great option for those trying to keep the pressures down:

I have to disagree with your statement about the pressure of these Warchief shells. 10,700 psi is not keeping the pressures down. That's right up there at SAAMI standards for the pressure needed to cycle a dirty, uncared for, semi-jammamatic.

My 390 and my Super X2 don't either. But I think even you, Harry, would agree that semi(s) jam quite a bit more than two barrel guns. Sorry if you take exception to my tongue-in-cheek nickname for self-loading, semi-automatics.
