From DemolitionRanch, “Firing 3 mags of M855 Green Tip ammo at AR500 Steel Body Armor. M855 is not considered AP but has a steel penetrator tip to allow for increased penetration, so let’s see how it does against some Level III body armor rated to stop up to .308.”
Green tips indicate they have a mild steel core not armour piercing. AP rounds, those have a tungsten core.
Good documentary, and exploded the myth that M855 is magic AP ammo. That green tip’s to make sure a target NOT wearing body armor gets penetrated.
I’d like, however, to see some tests run in gelatin, and in pigs, to see if the M855 still tumbles well in soft tissue, since that’s the selling point of 5.56mm – that the boattail bullets yaw and pitch in the body of the target and deliver lethal hydrodynamic shock. It’s a point that ought to be revisited since recent experience in Iraq and Afghanistan shows that local opposition weren’t reliably incapacitated by 5.56mm torso hits.
It also shows being a moderately poor shot pays – if you DON’T hit center mass, but do have a “flier” striking slightly above or below the plate on a live target, you’ve got a chance of nicking the subclavian, iliac or femoral artery of your target, which ought to take him out of play.
Place th body plate on gellotin not wood that would be as close as a human. Body.
I would like to see hoe body armor stands up to a hit while it is on gellotin which would be close to the human body mass.
I would like to see if the Russian pentiatrator round could beat 60 rounds to pentatrate
