Savage 223 with extraction problem

I have a friend's Savage model 11 chambered in .223 Rem. and it has a problem extracting spent rounds. The bolt will close and feed live rounds and snap caps all day long but you pull the trigger on a live round and you have to beat the bolt open to get it to extract the spent round. When I first got the gun from my friend, I cleaned it thoroughly thinking it was just dirty, but the problem presisted. Then I put a caliper on a live round, the neck measured .247", a snap cap measured .248" both of which feed and eject great; a spent round measures .254" a difference of .006". Knowing this, the only thing I could conclude is that the neck part of the chamber needed a little polishing. After using Fritz metal polish, patches, and a lot of elbow grease, the bolt still has to be beaten open to extract the spent round. This issue just started happening this summer.

Any thoughts of what else can be done to get the gun to extract spent rounds?

You are asking about an extraction problem, not an ejection one.
Ejection only happens after the case is extracted from the chamber.

First, what kind of ammo are you using.
Over-pressure reloads, mil-spec 5.56 in the Savage .223 chamber, Russian steel case ammo, or a rusty/pitted chamber are the most common causes of extraction problems.

Case neck thickness cannot cause it, as a bolt action would have no problem at all overcoming that.

It is also possible the bolt, action, and striker are simply dry, and need lubrication on the locking lugs, primary extraction cam, and cocking cam in the bolt body.

You also need to carefully inspect some fired cases.
Look for:
*Scratch marks that would indicate a rough chamber.
*A bright shiny round spot on the case head that would indicate brass is flowing back into the ejector hole in the bolt face and getting sheared off as the bolt opens.
* Pierced primers, Blown primers, or Excessively Flatted primers, any or all of which would indicate over-pressure loads.
