    IIRC, these primers are a loose fit in Rio and Diana hulls. Use the Rio.

    Rio primers are larger in diameter than the Fiocchi, so using a standard sized primer like the Fiocchi 616 in a hull that was previously loaded with a larger primer can cause several issues due to the loose fit. If the shell is fired in an auto or pump and the primer falls out of the pocket, it can jam the gun or even cause damage if it falls in the wrong/right place. The primers could also "leak" causing hot gases to leak through to erode the breachface or even enough to reach the shooters face. If your firing pins or other breachparts are made of titanium, they can be destroyed by those hot gases. I'd seriously advise that you not do it. The Rio or Nobel Sport primers are oversized and should be a good fit if you insist on reloading thse hulls. I just won't consider loading any hull manufactured by UEE (RIO, Kemen, etc.). I have seen too many of those hulls with a migrated base wad to think it was an isolated incident. You can do a search for previous threads, since I have posted pictures, etc. The manufacturer wasn't really concerned when they were contacted.
