Bryan came up with a great question regarding Snap Shots and high Ballistic Skill.
Context: During last nights game when Cyclone Missile Launchers were Snap Shooting at Razorwing he thought about high Ballastic Skill and re-roll and how they work with Snap Shots and Flyers.
As the chart says with a 6 or high Ballastic Skill you have a chance to hit on a second roll if your first misses. Question he came up with was. How does that work with Snap Fire? Do you still need a 6 to hit with the re-roll due to possessing a high Ballistic Skill?
Example for high Ballistic Skill has firer with BS 7, rolling a 1. The re-roll would hit on a 5 or better.
Flyers can only be hit by Snap Shots 40k6 pg 81 under Hard To Hit.
Looks like the devil is truly in the details with this one.
40k6 pg 13 Snap Shots. Specifically bolded text.
If a model is forced to make Snap Shots rather than shoot normally, then its Ballastic Skill is counted as being 1 for the purpose of those shots
So your awesome Independent Character model with high BS (without Skyfire) can't re-roll when they miss because they possess a BS of 1 when performing Snap Shots.
This was a great rule to look up and learn.
