(((i can't help but feel that you started this thread because you got your feelings hurt reading people bashing your pet cartridge. you have staked your ego on the .223 and you either don't like or can't afford a .45 for your handgun. my advice is to get over it. if you like .223 and are comfortable with its effectiveness, then by all means use it. no one's asking you to do otherwise. but don't pretend it's the most effective rifle round you can use. it's not. and don't kid yourself that the .45 isn't one of the most effective SD handgun rounds. trying to compare the two is a false comparison.)))
I never got my feelings hurt over calibers, that makes no sense. I appreciate you taking the low road on your post. As a FYI I own firearms chambered in 9mm, .40, .45, .223, .308, .22 lr, and 12ga.
Back to my original post:
I am not comparing CCW ability of the weapons that shoot .45acp and .223. I am not comparing the fact one is found mostly in rifles (and some pistols) to a pistol only. I am trying to figure out why people have such a high opinion of the .45 being a "man stopper" and the 5.56 as being anemic. If the object is to stop the threat (a human threat) I fail to see how the .45 would outperform the 5.56 assuming identical shot placement.
Many people I know put the 5.56 below the .45 as far as "man stopping" ability in self defense. Well they won't admit directly to it, most of the time (much like in this thread) the comparison is scorned as being apples to oranges, which means nobody has to give an answer. Its easy to say the 5.56 is anemic when you compare it only to other rifle rounds. Just like the .45 is at the higher end when you only consider pistol rounds. A cartridge is a cartridge, when you go from a .45 to a .223 your not training in smokeless powder, brass, and lead for a lazer beam.
I understand its hard to decide .45 vs 5.56, because if you just compare them to rifle class or pistol class, you don't have to admit to one being better then the other. Nobody wants to say that they would take a pistol caliber over a rifle caliber, since that would go against the common opinion that a handgun is only used to get to your rifle.
For a even easier time, rate these when it comes to your believe "man stopping" ability:
#1 .45 pistol 5 inch barrel VS AR-15 pistol, 5.56 Both full metal jacket
#2 .45 pistol 5 inch barrel VS AR-15 pistol, 5.56. Both with expanding/hollow point ammo
#3 .45 pistol 5 inch barrel VS AR-15 rifle 16inch barrel Both full metal jacket
#4 .45 pistol 5 inch barrel VS AR-15 rifle 16inch barrel Both with expanding/hollow ammo
