So My Leman Russ with a Battlecannon chances across a unit of 11 Xenos after moving 5.9", so I get to shoot my turret weapon twice, because of grinding advance.

Do I:

- get 12 shots (6+6) right off the bat, roll to hit then wound for all of them. (or probably more correctly, roll for the first 6, then for the next 6, but few players actually play that way)

or:

- get 6 shots, roll to hit and wound, then if there's been a casualty get D6(min3) shots on the second shot?

At what point is the number decided for the Type of the weapon, right at the start when I originally 'target' the unit, or after my first shot, when I 'target' it again.

I figure if I have a unit with multiple blast weapons, then they all get fixed at the start, but does the second shot for Grinding advance work differently?

Edit: I re-read. You shoot the weapon twice, you don't shoot it "again". This is an important difference. If it said "shoot again", then you'd roll the first batch first, then the second. Instead you "Shoot twice", so you resolve both volleys at the same time, as if you had 2 Battle cannons equipped (but must fire both at the same target).

In other words, a Leman Russ with Battle Cannon and Heavy Bolter would fire the following weapons:
Battle Cannon (Can fire at any target).
Battle Cannon (Must fire at the same unit as the first Battle Cannon).
Heavy Bolter (Can fire at any target).

Two things;

#1 - You need to move less than 5". I made this mistake a lot with my new Leman Russ, but they have a movement of 10" not 12"!!

#2 - You get 12 shots. When a unit with more than one blast weapon goes to shoot, you determine number of shots after choosing their targets, before any attacks are made. As such, since the Battle Cannon "chooses" both of its shots right away (it's locked into it), it'll be 6 shots both times, regardless of casualties inflicted by the first set of shots.

BCB, check page 17 of the free Core Rules, the section on "Blast", note #2. It says you determine the number of shots when you choose the target. The timing of the shot doesn't matter.

And yes, you're right, shooting "again" and shooting "twice' is an important distinction here.

Yup, I re-read the rules for "Shooting again" in the BRB and realised Leman Russes don't "shoot again".

I agree, but if you have a Blast weapon and the unit "Shoots again", then you would re-check the unit size since when you "shoot again" you go though the entire shooting sequence, including choosing targets. For example, Tyranid Warriors with Barbed Strangler and the Single Minded Annihilation stratagem. If you shoot the Barbed Strangler at a unit of 11 Grots, and 2 die, when you "shoot again", the unit is only 10 strong so you don't get 6 shots with +1 to hit, you get between 3-6 shots and no bonus to hit since the unit is only 9 strong.

Ah, I think that's the distinction I hadn't made, the difference between 'shooting twice', and 'shooting again'. Yeah that makes sense now. Thanks!
