Well you are not imagining anything. The Fiocchi 45 that I bought a whole case of, is warm. As in 900-950 fps with a 230 gr bullet warm. The bullets in those rounds seem to be seated deeper than most other brands. Shorter OAL. They are also small primer pocket brass.
I have half a case of 115gr 9mm Fiocchi as well and think that stuff is good. I didn't crony those yet though.
