Another poster has supplied a excellent site with bullet performance chart. Lucky Gunner http://https://www.luckygunner.com/labs/self-defense-ammo-ballistic-tests/#9mmhas an excellent chart which shows you bullet manufacturer, weight, penetration through 4 layers of denim and ballistic gel, expansion, and muzzle velocity. If you tap on the penetration section of a particular bullet it will bring up a picture of the ballistic bell penetration. Tap on the photo of the bullets and you can see the actual expansion of the 5 rounds. Want details on a particular bullet tap on the section titled Ammo and you will get detailed info on that bullet including a video on the first shot into the bell.
