Is it extracting the case from the chamber but not ejecting it, or is the case stuck in the chamber?

[Shooter McNasty]

Its extracting but not ejecting. The next round in the magazine is also chamring

OK - next question - is the ejector pushing the empty out of the bolt face, or are the empties still stuck in the bolt face?

[Shooter McNasty]

They look like they extract but dont clear the ejection port
