I have been hit twice by the U.S. .30 carbine round, once by a ComBloc 7,62 possiubly 7,62x39, maybe the Czech 7,62x45, which was commonplace among the bad guys at the time where I was, and once by a 7,62x54 bolt-action Mosin-Nagant rifle round.
The hits from the carbine were like a good solid punch but missed bone and neither did serious damage nor incapacitated me. The 7,62 short hit was in my left hand, entering my palm [Hands up! Don't shoot!...(not really)] and exiting behind the root of my thumb. The hit from the Nagant was from behind, felt like I'd been hit by a baseball bat and I woke up two days later in the Australian *Vampires* 8th Field Ambulance hospital at Vung Tau. Ow. I was told by my doctor that having bullets pass through my body was injurious to my health and that I should give it up. But if I have to get hit again, first choice would be from a 5.56 M855 62-grain ball round from beyond 300 yards; 7,62x39 M42 AK round from beyond 200 yards would tie for *I'd rather be hit by one* honours. Next choice would be from a M193 55-grain M16A1 round, also out past 200. Third would be the current Russian 5,45x39 round of the AK74- they really do tear out chunks, close AND at a distance.
I haven't seen a hit from the new M855A1 ammo for the M4 carbine yet. We shall see.
I highly recommend not volunteering for target practice for the M855A1 ammo for the M4 carbine....
Thank You for your service!
