Armor piercing rounds:
Armor piercing rounds are experimental right now heres the characteristics: they do 50% less damage, take highest priority in being fired, completely ignore armor and mob armor, damage doesnt change over different guns (meaning using a tr301 wont be any different from a gp37 in damage), and do small damage from impact.

nato5.56x45mmAP = -42 health damage
warsaw9x39mmAP = -60 health damage
warsaw5.45x39mmAP = -44 health damage
warsaw7.62x54mmAP = -100 health damage

Some idea for how far you gun goes:
12 = boomerang distance, 22 = edge of your screen if you zoom out all the way
30 = 33% farther than the edge of your screen.

The damage numbers where originated from the stalker wiki under the rifle's info call of pripyat version multiplied by x3.75. For example FS2000= 32x3.75 =120.

The FS2000 and Tunder S14 use their underbarrel grenade launcher as third priority and regular bullets as second. So putting your bullets inside a backpack and removing it is a good idea on switching to the grenades I don't know how to program "widgets".
