It appears those are fired cases. If so, fired cases ALWAYS match the ID of the chamber perfectly. Therefore, I'd say that they were fired in somebody's custom chamber that looks just like those fired cases.
This would require cutting a new chamber (and probably not in an AK-47). The reason for this, is to provide a better bullet alignment for better accuracy. The reamer was probably modified by someone looking for an affordable accuracy gain.
Those cases appear to be perfectly reloadable.
