Weapon Penetration Tables

well i was wondering since the old site s2hq has been dead for years.. are there any sites with the full listing of the weapon penetration tables.. i dont have sentinels nor can i find it for sale here 4 years later and would love to know which weapons give max penetration etc.. ive found the ray weapons to penetrate at least 5 walls of concrete from my editor testing but thats to much work to test each weapon in that fashion

exploding headshots question

ive enabled this in the cfg files and what am i supposed to expect? arent there heads supposed to explode when i get a critical headshot? im checking the console on a succesfull critical headshot and yet there heads are remaining intact
