Dead Shot and double-barreled weapons...

[Maxximilius]

... I already know that you can shoot with both barrels during a Dead Shot.

But :

- are these two separate attacks, essentially being treated as a double Dead Shot ;
- or is it a single shot, with essentially each attack from your BAB being doubled at the cost of a lower bonus to attack for each of them ?

It's important for the purposes of weapon qualities like Flaming Burst. Doing a critical hit on each bullet shot from Dead Shot would add 6d10+2d6 to the final damage.
Doing a critical hit with only one Dead Shot would add only 3d10+1d6 but could ultimately hurt more.

I'm pretty sure you only hit once at all, and a level 11 double-tap Dead Shot with a +1 weapon and a +5 Dex modifier would look like this : +13/13/+8/+8/+3/+3, even if you ultimately fire two bullets... odd exception.

Bump. Need to know if a weapon property adds to both bullets, or if each barrel must be enhanced separately ; and if these properties affect Dead Shot once or twice.
