that is called a dynamic address, Find the pointer to this address and you're set. It has nothing to do with your player.txt file. most of that except the graphics is server-sided. so changing it won't even effect anything. believe me I've tried. get your hands on a UCE or a MHS bypass, and get the address for the ammo, and (in CE) right click on the address, and select "Find out what writes to this address" and you will have your pointer for ammo.
