Lately I've read a couple posts (not sure where) that Fiocchi was not working in various guns. Not at all. I've shot quite a bit of it in the past with no problems, but who knows if current production might not be good? And WWB is not noted for being great ammo.It choked on Fiocchi and WWB, and some other brand they had at the range.
The Fiocchi (supposed to be a great brand for 380s), I only shot 6 rounds of that brand (it was my last box to shoot), and it jammed on 3. I quit after the last one and just packed up for the day. I have had 2 trips with it so far. I think I am done with the gun.
Blazer brass is basic range fodder but has always worked well in any of my guns. Perhaps you might give it a try? You said it likes PMC also.
Maybe you can give it a rest and then try it again later? Maybe not, though. I know that I've had guns that just would not work for me no matter what I tried - even when others could shoot that particular gun. One notable one was that Kimber micro Raptor which was the most beautiful gun I've owned, but pretty is as pretty does and the gun hated me. After several range trips I gave up and put it for sale on consignment.
