My first thoughts are
1) chamber rough. Clean and polish for better release of expanded case under pressure.
2) Extractor failure. You already mentioned replacing this, but if your chamber is rough, you're starting ahead of the problem, it will catch up to you. Sounds like you like the barrel, a chamber polish may well clean up and make your issues go away, and leave you with a barrel to be very happy with.
What does your fired brass look like? Any evidence of roughness or failure in post finish-reaming polish?
Gas system checks.
Buffer tube smooth allowing easy travel rear and return? Buffer spring good?
Good luck.
