JFC that's a long ass way of saying I'm right. Try again BS, it only takes one sentence to say you were misinformed, and I am correct.
And it only take one sentence to admit you didn't realize the context I was speaking of ... at
under 10m, like a classroom. You kept mouthing off about pistol against rifle, without even hinting you saw that.
Of course a pistol caliber sucks at range. It's inaccurate, loses energy fast, has a massive cross-section for its profile that introduces drift, is traveling slower so there's more drop, etc...
But that's
not what we're talking about. What we're talking about is the ability of the bullet to
hit a vital organ! Or create a cavity or other area good enough to cause fast bleeding out.
Which brings us back to modern, defensive, civilian 9mm cartridges, loads and bullets ... versus common, civilian .223/5.56 cartridges, loads and bullets ...
within 10m.
That said ... even I admitted the FBI has
recently gone to great lengths to recommend SWAT and their own HRT loads for .223/5.56 in CQC. The FBI is doing more and more research and testing, just like they did for pistol rounds. Why? Because a lot of teams carry an AR-15 and
only have a .223/5.56 bolt/barrel. But it's 25 years behind, and has barely a decade of such.
They don't have a lot of options and budget like operators do in the military, who don't have to deal with the inadequacies of the .223/5.56 by replacing it in their AR-15 compatible platform.
