The Red Cross did infact make an objection to the 5.45x39 Soviet service round. The bullet has a 1-2mm air pocket in the nose of the bullet which causes it to deform on inpact causing the bullet to tumble immediatly upon entry. The bullet is very long and slender which aides in its "fish hook" type wounds. The round rapidly changes direction and tumbles through the target while shedding shrapnel from the jacket. Its wounding mechanism relies much less on velocity than conventional 5.56 rounds. AK's have a very rapid barrel twist which spins the round very rapidly resulting in increased accuracy and complementing the already flatter trajectory of the round. Testing with slower barrel twists cause an verly slight vertical "wobble" which makes wounding even more profound, but sacraficing some accuracy...this is academic though, as accuracy and AK are
unrelated terms. The Russian 7N7 round also has exceptional penetration qualities. It uses a hardened core with a "knocker" in the base of the bullet which impacts the base of the hardnend core upon impact increasing penetration which makes it superior to the M855 against something like a light vehicle. This bullet is the most lethal assualt weapon round in service today, I have found it to be more lethal than both my favorite 75 grn TAP and some MK262 I got for testing....both of which are illegal for ground warefare. Its wounding mechanisim is much less velocity dependent, which is essential for poorly manufactured and inconsistant Soviet ammo. Afghan rebels called it the "posion bullet" as countless numbers were killed from wounds to extremities. This round produces a mimimal ammound of recoil, less than 5.56 and using Wolf and the compensator flash/muzzle climb is non-existant making extremely rapid accurately aimed fire
very possible. The Red Cross appealed to the UN, and obviously NATO objected to more Russian brutality, but the round is perfectly legal for use as it doesn't violate the laws of war, it merely circumvents them, as do our fragmenting 5.56 rounds....they just did a WAY better job. Our weapon, their round improved by newer technology would likely be the ultimate assault weapon.
