Many .22s' ejectors are not exactly flat on the engagement surface--should be perpendicular with the bore line.
A little small file work or a diamond stone can usually do the trick in about five minutes. Also check the forward angle to make sure the barrel's extractor notch surface is NOT camming the ejector away from the rim. Same type of fix.
End result is often a "sharper" corner on the extractor's inside faces.
Remove the action. Drop the hammer. IIRC, you take out two screws to release the fire control system from the receiver. Be careful that you don't let the two sides fly apart and release all the parts everywhere!
To get the bolt out, you'll need to fiddle with the handle. It will slide out or push in, perhaps at some special location in the travel stroke. You might need to tip it up to disengage the back notch from the bolt itself. Only then will you get the bolt out and be able to drive out the pins holding the extractor in the bolt.
Sorry I can't remember more details. It CAN be done without bending/breaking/scratching anything.
