Can you stand and shoot with the multi shot? Rules for multi shot say "some missile weapons enable their users to shoot several times in each shooting phase - known as multiple shots" Since charging occurs in the movement phase, and not the shooting phase... can you still multishoot?
In the Feb 2009 FAQ they errata'd (errataed? errated?) the above mentioned sentence to say: Page 55, Multiple Shots, the first two sentences should be replaced with: ‘Some missile weapons enable their users to shoot several times – this is known as multiple shots. The number of times the weapon can fire is given as part of its description (e.g. a Dark Elf repeater crossbow can fire two shots, so it is noted as having 2x multiple shots). [...]’ So they can multishot any phase, not just shooting. This is, of course, the opposite of what happens with the High Elf reaver bow, which doesn't have the multiple shots rule but does say it fires 3 times in the shooting phase. The FAQ confirmed it is shooting phase only.
