Hitting Multiple Targets with Scatter Weapons?

By hacxattack, in Rogue Trader Rules Questions

Hello all, I have a question.

The description for a shotgun in the armory has a part that reads "their ability to hit several targets with a single shot make shotguns appealing to those with little actual skill in shooting."

Are there any actual rules for hitting multiple targets with a scatter weapon? I've seen this description in several books, so it doesn't seem like an accident. Any information from any rulebook would be helpful.

Thanks,

EB

Hmm. Treat it like Full Auto, 'walking' the shots to another target, losing two degrees of success for every metre you move?
