See, I thought this was a forum of like-minded enthusiasts who could have intelligent, civilized discussion. But I guess attacking people's opinions and calling them "Mall Ninjas" is a better way to promote community.
Obviously I didn't think that a knowledgeable gunman would take my claim as shooting in the "general direction" at face value. What I really meant is you can afford to be LESS PRECISE with your aim (which is a common occurence under stress)
But since you seem to more of a facts oriented guy, let's present some of those.
At a distance of 5 feet or under, a 18" barreled 12 gauge shot gun (using 00 buckshot) will provide a 2" spread, carrying the wadding into the wound with the pellets, and creating a solid 2" hole.
As distance increases to 10 feet, your looking at a 4" hole,
at distances greater than 20 feet, you no longer had a solid hole and instead have a spread of pellets 9"-12", creating a still incapacitating and quite probably fatal injury, and no chance of wall penetration.
So, just using straight statistics, as compared to .223
@ <5 feet, you have a 450% greater allowed margin of aiming error
@ <10 feet this increases to 900%
and @ >20 feet this increases to 2500%
As compared to .45 ACP these numbers are 225%, 450%, and 1250% respectively.
If you would like to reproduce these numbers on your own to test for accuracy,
Now you may argue that these percentages represent only inches in real life, but when shot placement counts, those inches could make the difference between life or death.
And as for penetration, I've actually run my own tests (based on an article I read).
Using leftover drywall from a remodel I did (fully intact) I simulated walls by connecting two pieces of drywall to 2x4 studs and stuffing the insides iwth left over insulation material.
I set up three walls at 10 foot intervals, and started shooting.
Both Hornady TAP 55 grain and 60 grain (common "self defense" rounds)
Penetrated all three simuated walls, although some of the 60 grain bullets had begun to fragment by the third wall.
45 ACP penetrated also penetrated all three walls, as did 9MM, and exited the third wall
The buckshot also showed some penetration through the third wall, but the spread was widened to the point where much of the buckshot didn't even hit the wall, and there was a significant amount of spread between each piece that did.
At the end of the day, its still your personal choice, but a 1250-2500% greater allowed margin of aiming error, and a lower chance of accidental injury to inhabitants was enough for me to go with the shotgun as my weapon of choice for home invasion.
but hey.... What do us uneducated mall ninjas know?
