Heh. I'd like the official ruling too, but I never made an account at WotC. I don't have time to do a ton of messageboard browsing, so ENWorld is pretty much my one-stop shop. If Mistwell's got time for it, that would be cool, though.
I can really see both sides of this argument. With a finite number of bullets, I can see the argument that a Reflex save lets you avoid all of them -- but most Reflex saves result in half damage, not no damage. There are SOME that are for no damage -- some traps, and Blade Barrier, offhand -- but not a ton.
My first read made me think that it was "Reflex save avoids", which means none. I look forward to seeing how it ends up.
