I know very little about guns, ammo and/or hunting. But I’ve heard two things that seem contradictory, so I’d like some info:
(1) I’ve heard (I think on This American Life) a length and knowledgeable-seeming discussion of what kind of gun you’d need in order to kill a T-Rex if you were being attacked by one, with the consensus being “some kind of frickin’ enormous rifle, and hope you’re lucky”
(2) I’ve also read/heard various descriptions of types of bullets, such as “hollow point”, which are designed to do gruesome amount of damage to people when fired out of a pistol, ie, the entrance wound is the size of a bullet but then the exit wound is the size of a grapefruit.
So… seems to me that a fairly small gun hitting T-Rex at the center of mass could still do a relatively huge amount of damage. Say, an uzi firing hollow point bullets. If I can point it at his belly and hold the trigger down and hit him with 5 or 6 shots as he charges me, and each one punches a hole the size of a grapefruit all the way through his torso, isn’t that going to put a pretty serious hurting on him?
