Anyone who has done junkyard shoots know that a ANY jacket out there isn't going to stop a 124gr 9mm bullet traveling at over 1200fps. Either the bullet passed through something else first, impacted something hard on the opposite side which prevented it from penetrating, or the cartridge was defective.
I once shot a whitetail in the neck at about 80 yards with the .223 Winchester 64 grain Power Point. Way before bonded. Deer dropped in its tracks. But, upon examination the fully expanded jacket was hanging out of it's exit wound, which was only about an inch away from the .223 cal entrance wound - yeah, on the same side of it's neck. Bullet apparently bounced off it's spine and came out nearly the direction it went in.

I saw an air marshal do that at a class. He was shooting .357SIG Gold Dot for the entire class and the first words out of my mouth when I saw his training ammo was, "Holy ..., are you an investment banker or something?"
He just looked at me, shrugged and said, "They give it to me for training."
