Wargear/Vehicle Upgrades Questions.

As a recent Dark Eldar convert, I have a few rules questions that I'd like to address in preparation for an upcoming Combat Patrol tournament.

1) Hexrifle: Does this weapon still deal a conventional wound, regardless of whether the victim passes or fails its Wounds test? I assume it does, but the wording is a little iffy and I can't seem to find any confirmation either way.

2) Shock Prow/Chain-Snares: If I am reading the rulebook correctly, a Raider with both of these upgrades would do its chain-snare damage whenever it tank shocks an enemy unit. Is this correct?

I've learned quite a bit from these forums over the past few months, but I don't recall seeing either of these questions come up. Hopefully somebody can guide me to the correct interpretation of the rules.

Thanks!

1) Yes it still deals a wound. The secondary effect is only triggered by an unsaved wound.
2) This one is a bit less certain. The chain snares work on any unit the vehicle passes over but with tank shock you're attempting to go through them instead of over. You're forcing them out of your way so you don't really go over them. I'd probably say no but it's a bit of a grey area.

Thanks for clearing those up, Adhemar! I think your interpretation of the chain-snare/tank shock situation makes perfect sense.
