I recently chrono'd a few .32acp loads out of a Beretta 81. Generally, I'm not interested in hollowpoints in this caliber, so all these are solids of one form or another. All ammo was purchased within the last year. Ambient temp was around 80F.
Geco 73gr FMJ (no advertized velocity): mean velocity 917 fps
Fiocchi 73gr FMJ (advertized velocity 1000 fps): mean velocity 988 fps
Underwood 55gr +p Xtreme Defender (advertized velocity 1050 fps): mean velocity 1158 fps
Buffalo Bore 75gr +p Hardcast Lead (advertized velocity 1150 fps): mean velocity 1006 fps
My own conclusions: I no longer trust any numbers published by BB. Underwood substantially outperforms their own published numbers (they probably tested with a Seecamp) -- it's a genuine supersonic load out of this pistol. Fiocchi numbers seem close for this pistol. Geco is a modest performer, but I'm guessing it's still a bit better than the SAAMI-spec stuff like Winchester.
In terms of kinetic energy, BB just barely edges out the Underwood (by less than 3%), due to its greater mass. Both have slightly more energy than the Fiocchi, but the gap is small enough that it seems irrelevant. There is a fairly substantial step down in energy to the Geco load.
