 Jonathan said, I don't know what that other caller was talking about, but the effective range of a 5.56 round is 600 yards. Yeah, from what I have read too about the fire, and again, I don't know all of the details about the firearm and the ammo. I don't know any of this stuff yet. I've not seen this stuff confirmed. I've not seen a full report yet done up. I'm not saying it doesn't exist. I just haven't seen it. Okay.
