U need it to a certain extent, 5.56s dont drop grown men all the time so if a 5.56 aint always dropping everybody while a .223 is the weaker round then where does that leave the .223...
Thats why Im gettin a AK so I can have some take down power while I have my 5.56 chambered AR for accuracy... thats just me
And this is for shyt hit the fan scenario.
But yeah home defense i wouldnt touch a rifle. Whats a good shotgun? (I havent got one yet)
You must live in Marvel Universe if you're hitting someone with .223 or 5.56 and they aint dropping. That or you just need to be more concerned with shot placement.
This is pretty much the same argument of 9mm vs 40 in my opinion.
My opinion is that unless you're in a 1 bullet 1 shot scenario you don't really to have to be concerned. For the most part if you have to shoot at someone youre generally going to shoot more than 1 time and unless they are on bath salts or pcp or some shyt if they get hit even once they are going to consider escaping the situation. That is unless you have them back against the wall in which case they may try to empty the mag on you (to save their life) or due to shock or injury they may fall to the ground or stumble and trip trying to gtfo.
You have a very slim chance of getting into some sort of standoff with someone and even if you do then if it isn't them that decides once the first few shots ring out, it might be you that decides to get the fukk out.
