I really don't see a need for a sensor. The mechanism should just eject a shell right after it has been fired.

Basically, it will be motorized plunger since, like you said, flywheels won't work with shells.

It would have a shell-sized bolt sled that feeds shells into the chamber, one at a time. When the bolt is forward, the plunger releases and fires all the darts in the shell. Then the bolt comes back, and ejects the shell, similar to how the Trilogy DS-15 does it. When it returns, it takes another shell from the magazine.

Buzz Bee was able to do it, albeit not motorized, nor very reliably. This might be a little more challenging due to the shells being bigger, and not cylindrical.

This is my idea anyway. Yours might be different.
