I don't have pressure equipment, but velocities with Fio 616s usually fall between those with the mild STS209s and the hotter Win 209s.......I'd say they're closer to the Winchesters. Brissance charts are problematic, as rankings can change with even a change in payload, as Tom Armbrust's site shows. Over on the reloading forum at shotgunworld there are a number of folks who feel you can use Winchesters and Fiocchis interchangeably. I would agree, provided you aren't anywhere near a maximum load.
