People laugh about it being a small caliber. Make no mistake its a nasty little bitch.

Typical 5.56 round is high velocity round and causes wound cavitation, very common in bullet impacts. Training in combat life saving teaches about it. Medium to high-velocity projectiles create a pressure wave forcing tissue out of the way, creating a cavity that can be much larger than the projectile

Sure but now we must know. M193 or M855?

M193.

855 is a compromise round created to improve barrier penetration (car bodies, walls, glass, etc) out of shorter 14.5" M4 carbines. Mostly its because the round stays together better than m193 which tends to shatter on contact with anything. 855 not an "armor penetrating" round. M193 has far superior soft tissue performance, especially out of longer barrels (20", but 18" works too).

That said, M193 is actually better at body armor penetration at close range because speed kills armor...not weight or round composition, m193 is faster, and "steel penetrators" are bullshit.

That wound is classic for what m193 does in soft tissue.

Didn't they come out with a newer one that does a bit better than 855? I'd go with 855 for the penetrator though.
