In addition, Praetorian headshots actually do 2x damage, not 1.4x. Here's how it works:
Scenario A) Double Hit when faceplates are up:
Shots hit as follows: Ammo damage, bodyshot, pen ammo dam, pen (bodyshot or headshot, depending on where you hit. Headshot does 2x damage)
Scenario
![B)](https://lvlt.forum.bioware.com/public/style_emoticons/default/cool.png)
Shots hit as follows: Ammo damage, pen ammo dam, pen (body or head shot, depending on where you hit)
It is also occasionally possible to get a full double hit as when the face plates broken.
Depending on where you hit, you can also get regular bodyshots and regular headshots
Scenario C) Double hit on the Praetorian bubble
Shots hit as follows: ammo damage, bodyshot, pen ammo dam, pen (body or headshot)
Scenario D) Double hit from behind the praetorian
Shots hit as follows: ammo dam, bodyshot, pen ammo dam, pen bodyshot (needs lots of piercing)

Note that we got similar results on both barriers and armor in terms of numbers of hits and damage done. I just excluded the numbers for most, to declutter.
Much thanks to OnlyUseMeGI and corlist for their help.
