The 5.56 does go fast enough to go right throught the other side, but its so small the mass of it is just to small to do real damage, or enough for physical trauma.

I'm glad someone agrees that the 5.56 is underpowered. Most "experts" I talk to say the 5.56 is the best thing to ever happen to the military. -.-
