Yesterday I shot my Kel-Tec P32. It has had reliability issues in the past, and the new ammo I tested yesterday didn't help. It had a couple of jams with Fiocci 60-grain HP rounds. I also tested the penetration and expansion of the hot little Fiocci HP's compared to Fiocci, Rem-UMC, and Winchester FMJ rounds. They all penetrated soaked-wet newspaper about the same depth-- about 5 inches. Which is adequate, I think. For comparison purposes, a Speer Gold Dot 9mm +P, 124 grain went about 7" deep and opened up to .50, and a .38 snubbie revolver pushed a 129-grain Federal Hydra-Shock +P about 9" deep--but the .38 special HP bullet didn't expand a bit. That was a point-blank shot into the newspaper from maybe 3 feet away. The Fiocci 60-grain JHP rounds seemed more powerful than the FMJ loads, but they did not open up and they did not penetrate any more. They did have deformed noses and the hollow cavities did open up a bit, but not enough to increase the overall diameter of the bullet though. I did not notice any greater diameter wound channel, despite the higher muzzle velocity and wider, flatter tip on the hollowpoints. I'm disappointed in the 129 grain .38spl Hydra-Shocks. They performed just like a standard all-lead 158-grain semiwadcutter (either HP or not; since neither one will reliably expand from a 2" barreled snubbie anyway).
