Is there any information regarding how many rounds a bolt gun clip carries? Also how many round a bolt pistol magazine would have? Along these lines how many times could a standard SM flamer be used?

I know in Space Hulk there was a cap on the number of times the Terminator flamer could be used as well as the assault cannon. It was pretty much to balance the game but it got me to thinking and wondering.

I'm putting together a scenerio where ammo is going to be accounted for and thought perhaps someone might be able to help.
