I never use Full Metal Jacket loads for stuff like that, those are mainly for plinking around.
Unfortunately those in the military don't have that option... it's no wonder AKs and G3s picked up from the enemy are preferred. If you have to use ball ammo, bigger is always better. Though a pocket knife on the tip of a 556 works wonders in fixing that. Geneva convention be damned when my life is on the line, esp. when the other side isn't expected to adhere. It's quicker and more humane than poking holes in them, and more importantly, it's harder to fire back with an AK when there is a 10" chuck of meat missing from your shoulder.
The nylon tip isn't designed to fragment, it just allows the bullet to behave like a hollow point on impact while retaining the in flight ballistic profile of ball ammo. Hollow point on the 556 always implies fragmentation since there isn't enough bullet to mushroom and stay whole.
It also protects the rounds in the magazine from having their tips deformed from severe recoil with larger calibers, and allows pointed ball ammo to be used safely in rifles with tubular magazines where a hard tip would otherwise impact the primer of the next round.
Anyhow in your case, a hollow point 556 is pretty much going to fragment at any velocity. With ball ammo you are relying on the shear stresses to tear the jacked bullet apart at the canelure as the bullet rotates 90 degs from it's flight path. Heavy end of any moving object has the most inertia and will be less effected by drag than the lighter end when moving through a medium, thus causing a net torque that causes the bullet to rotate 180 deg and exit heavy end first. A tiny 556 ball bullet with a weak jacket and canelure crimp and hitting at 2700+ fps cannot support the internal forces necessary to hold the bullet together as its flying through the target at 90 degs, so it breaks apart and microperforates the tissue; tears a chunk of meat out at the dotted line if you will.
Thats really the only thing that allows that .223 cal bullet to achieve the incredible wounding potential that it does (anyone whos used one has probably seen the unexpected and completely disproportinate size of the exit wound compared to other calibers).
Use ball ammo and a short barrel and you are basically going into combat with a .22 LR that merely pokes the enemy with .22" holes.
