LOL, the guy talking about killing effectiveness, calls 5.56mm ammo '.556' which would be the equivalent of 55 Caliber.
Right.
All credibility with regards to caliber, or round diameter is out the window now.
I'm gonna go shoot a deer with .762 bullets, that's the NATO round.
Oh, you mean 7.62mm not .77 inches diameter right?
Uhhhhhh.
I'm getting a very Longtabber type vibe from this guy. NOBODY calls 5.56 rounds ".556" NOBODY, NEVER, EVER.
