Guardian Skulls: Ammunition Capacity

By IdOfEntity, in Dark Heresy Rules Questions

Just as it reads, I had two quick questions concerning the Gun-Skull variant of the Guardian Skulls found in The Inquisitor's Handbook, page 144.

1) Were Gun-Skulls meant to have a single amunition pack? (Charge-Cell, Auto-Clip, etc)

2) Does it take the same amount of time to reload the Gun-Skulls weapon as it does to reload your own?

I hadn't seen anything official on this, but I'm assuming that the answer to the above are both "Yes". Have you played it any other way?
