I can’t speak about Fiocchi paper hulls, but I am on my third and most likely final loading of Cheddite 2&1/2” 12 gauge paper, initially purchased from BP. They are not as well constructed as Federal Papers and by this third loading many no longer hold a crimp and the walls are collapsing. The external paper covering has separated from a cardboard interior. No brass separation, even with a hefty self-opening SLE. Not sure they were worth the cost but I used up all my Fed. papers, and I do like the aromatherapy.
Good luck.
