How does an auto-eject system work?

I'm taking a 3D modelling for game design course this quarter, and our first assignment is a weapon design. In the interest of modelling/texturing accurately (and for personal knowledge,) how does an auto-ejection system work on a break-top revolver?

Also, is there anything unusual about the operation of revolver that would prevent it from firing shotgun shells (given an approriate bore size and barrel length, of course.) Thanks for any advice!
 
In brief, the extractor star is pushed out by a cam centered in the frame hinge (the break-open axis). Once it reaches full extension it drops off the edge of the cam and goes to the closed position for reloading. Closing the revolver resets the cam for the next extraction.

Shotgun shells: The cylinder would have to be long enough to contain the open pedals at the end of the shell casing after firing (about 1/2" extra). And the cylinder to barrel gap might play havok with the BBs, since the would encounter a lip - but the wad might prevent that.

It wouldn't be very effective, but whatever. .410 shell revolvers are currently made.
 
Great, thanks, that's what I was looking for :)

Effectiveness isn't so much a concern as plausibility; I just wanted to try something different. Plus it's more fun and challenging to develop a concept grounded in reality rather than in sci-fi pseudo-science. :)
