So PPU bought and inbound. Quick look at the
Fiocchi specs:
Muzzle Velocity is 1190 FPS Muzzle Energy is 290 ft Lbs

PPU specs:
Muzzle Velocity is 1280 FPS Muzzle Energy is 413 ft Lbs

I tried to do some research and see if there was any error in these numbers, the Fiocchi Muzzle Energy varied a bit, but less than 5%

That is a huge delta in muzzle energy so that would explain why the PPU is better at working the toggle and cycling the next round. But is this TOO MUCH energy?
Folks have had good luck with this ammo at 7.65 and the Luger?

How does PPU get such a bigger energy in the same casing as the Fiocchi?
