Hi all, first post here. As usual it's going to be a problem post...

I bought a savage-made No4 rifle at a gun show, so no returns available. The bolt and the receiver numbers do not match, but I marked up the lugs and they look like they have pretty decent contact on both sides. One side is slightly better than the other (the long lug contacts slightly better)

I did some shooting with it the other day, and for the first time since I bought it, and I have problems on primary extraction. I'm using MEN-83-8 surplus ammo which goes into the chamber with no problems whatsoever, and I have no problems extracting unfired rounds. When the round is fired however, I have problems getting the bolt to open. I have to smack it upwards to get it to turn all the way open, after which I can always get the case out.

Fired brass does not go into the chamber easily, although some cases do go in easier than others, but it's a tight fit or requires a bit of a smack on the bolt. I assume the chamber needs to be polished, but I'm hesitant to do so without using the right tool to start with. Do you have any recommendations for honing tools? Am I on the right track here or is there something else at play?

thanks!

Before doing anything that may not be reversible, check the headspace with the proper specification head space gauge. That would be the field gauge; which is 0.074". The bolt should not close on this gauge. Do not force the bolt when testing with the gauge; just feel for the point the bolt handle stops naturally without forcing.
Also check to see if the bolt head "clocks" in properly to the bolt. When screwing in the bolt head to the bolt body; how far does it go past the 12 o'clock position. 

Posting some photos of the bolt head clocking and the fired cases may help us see what's going on. 
Inspecting the chamber with a borescope is useful to see if there is any machining or wear issues.
I recently bought a USB type 5.5mm borescope for around 20 Euro's and it's ideal for this purpose
It's nice to be important, but it's more important to be nice!

Please pics are a huge help.
You might try a thorough cleaning of the chamber though. You'll do no harm cleaning & it sometimes fixes problems caused by a build up of hard carbon & brass.

Yes what Shamu said.  Use a bronze chamber cleaning brush on a chamber cleaning rod such as the brass Dewey Chamber Rod which has a fixed non-rotating handle and 8-32 threaded female threads that accept bronze chamber brushes (.308 sized brush works good).   Give it a good scrubbing in a twisting motion with bore solvent.  Wrap a patch around the brush and soak it in solvent and scrub some more.  Finally finish with a dry patch.

Carefully inspect the fired brass and see it it is bulged or distorted.  

Check headspace.
