And now Fackler would disagree with you, because he was one of the people who proved the theory of hydrostatic shock false.
1) The case of the 10mm auto round is larger than the case of the .45, so that explains that.
2) You forget pain [img]smile.gif[/img]
3) Pistol rounds are a bit of a wild card, since they possess greater disfigurement and maneuvering once inside the body. A near miss from a pistol loses some speed, changes form and gains "flaps", which turns it within the target and makes it travel in weird paths. A rifle's bullet will most likely just keep on trucking, with minimal turning.
