I recently purchased and fired three boxes of Fiocchi 38 Super out of my Colt 1911 and it was well made, worked great, and I had no FTF's. That said, I did notice that it seemed to be a bit hotter than the Remington +P 38 Super I also had on hand. The Fiocchi was the standard loading not the +P, and yet it was more robust. I did not chronograph them at the time so I don't know the actual velocities, I was just going by recoil and kickback. I would buy it again and I will chronograph it next time. Could also be the Remington ammo was loaded wimpy - just saying.
I also have a bunch of 38 special, 357 magnum and shot shells that are marked S&W in the blue & white boxes which were made by Fiocchi in the 70's. While the ammo does work OK, I have found that most of the bullets have oxidized quite badly. This ammo was stored in the same place and environment as all my other stuff that has had NO issues. My ammo closet is dry, heated and air conditioned so there is no humidity or heat build up. Granted, that ammo was made 40 + years ago so I guess they have improved it by now.
