The mosin I got at Christmas suffered from the sticky bolt syndrome during the first box of ammo. I discovered that the main culprit was where the protrusion on the bolt meets the top angled part on the receiver was roughly finished. I lightly lapped this area with some compound followed by a quick polish. I did this only because this area only assists with initial extraction during bolt rotation and does not affect any other geometry. This greatly improved extraction and along with the recommended chamber scrub, it now functions flawlessly.
I'm on the cell phone again so ill edit later so it can be understood better.
