You also demonstrate your ignorance of the terminal ballistics of rifles by lumping them in with handguns. I suggest you read the published works of Dr. Martin L. Fackler, and other members of the International Wound Ballistics Association to remedy said ignorance.
Fackler was not exactly a proponent of the hydrostatic shock theory you reference above. So you're kind of introducing conflicting sources and theories. Fackler was all about hemorragic shock.
Anyway, people really seem to get personally caught up in these discussions.
You'll note that I have not disputed that rifle rounds cause terrific injury, especially at close range. I've actually shot enough of them into living, breathing things to know with absolute certainty that rifle rounds to vicious things to bone and tissue. I've seen with my own eyes all of the phenomenon typically referenced, such as fragmentation, tumbling, etc. Rifle velocities will turn bone itself into a muscle and artery shredding missile ripping through flesh. It's nasty stuff. And effective.
However, even WITH that first-hand, direct understanding, I personally believe the shotgun is more effective at close range. I've seen firsthand the effects of 00 as well. And with my own, firsthand experience, I answer the OPs question with, "you want to keep your shotgun because it will do horrifically nasty things to the goblin that hulk-smashes your door at 3am."
That statement is true. It cannot be disputed. Shotguns are lethal. Period.
If your response is "sell your shotgun because rifles are ...... " that's fine as well.
What I don't understand is why it's so all-fired important that someone
must be right, definitive, and the end-all-be-all of all that is terminal ballstics right here in this thread and in this forum.
Shotguns are nasty.
Rifles are nasty.
I believe shotguns are nastier, and bring more nasty, quicker. You disagree. But if, zomg, you're
right and I'm.... oh dear oh my .... "wrong," .... it isn't the end of the world.
The OP and anyone else reading the thread and asking the question can make up their own mind.
However, someone did refer to the concept of shotguns as stoppers as a "myth." Can anyone provide examples/anecdotes of folks that kept coming after eating a couple of rounds of 00 in the chest?
