5.6 mm (and yes, not 5.56 mm) is enough - bonus points for those who know where this ammunition is in use.

Don't want to carry or shot a gun with 7.62 if it is not needed, too much weight, recoil and noise - Not that I had used those, but the smaller one was already loud enough for me.
Not really. Although enough A-Team to know how a car blow up.
Well, if you're the hero, then you don't need to hide at all. If your an antagonist, then start praying.

And if I like you, put at best some meters between those with the gun and you or some thick solid material...
