I never said that .380 HPs wouldn't expand. They will even from short barrelled pistols BUT not reliably at the lower velocities and WHEN/IF they do, they penetrate shallow. I can't speak to the Troopers story. I'm not sure of the point. Again though, what killed the Trooper? Penetration of the . 22 deeply into the body cavity. The . 357? I dunno, I'd have to read the after action shooting review. Too many variables: ammo type, barrel length and shot placement.
