30carbine in a pistol is a 110grn fmj going about ~1400fps in the carbine rifle its ~2000fps. hitting soft targets is different than shooting plates. you would be surprised just how difficult it is for bullets to pass through soft targets.
the automag3 is about the same power level as a 9mm handgun. its a helluva fun round to shoot due to the enormous fireball and loud boom but its not a magic bullet nor is it a particularly weak one.
"Gun control: The theory that a woman found dead in an alley, raped and strangled with her panty hose, is somehow morally superior to a woman explaining to police how her attacker got that fatal bullet wound." — L. Neil Smith
