I have used 3 different loads. Hornady XTP hollow point. Silver Bear Hollow Point. Corbon PowRBall. I have tested all three in water jugs a wet phone books. All three expanded nicely. If your gun will shoot anything; like a CZ-82; I prefer the Hornady XTP hollow point. But I also have some Silver Bear Hollow point. The PowRBall ammo is good if your pistol is picky and prefer FMJ. It looks/feel/feeds as FMJ, but it's a hollow point. All three expanded in water jugs and wet phone books. Other than shooting into a dead animal, that's the best test I can do; and that's fine by me.
