I just finished my conversion this morning. Already did my .223 and it works great.
For the S-12, everything hand cycles correctly. I loaded up my AGP 10 rounder tonight with Federal 1-1/8 birdshot and started firing.
First shell fires and ejects fine, and the next one feeds correctly, but when I pull the trigger again, nothing happens. I pull the bolt back and eject an unfired shell, then the same thing happens again.
Feeding by hand, the action "cocks" well before there is sufficient room for a shell to be ejected, but when firing it seems to cycle without cocking. How can this
