I have a Sako L-461 in 222 that I hadn't shot for three years. It looks a bit like a scaled down Mauser but is a push feed. It is very hard to get the extractor to snap over the rim while chambering a round. The angled face of the extractor is polished and smooth.  I never noticed it being hard to chamber rounds before but don't see how it could have gotten harder.

Anybody have one of these or know anything about this problem?

Without going and having a look at my bolt,I would think the spring and associated bits behind the extractor are jammed,try soaking in a penetrating oil for a while,then rock the extractor,it should move to allow the extractor to clip over the case rim.

I have had a look at my bolt and the extractor moves freely when pushed with my thumb,I would think your extraction system has seized up,there is a spring ,plunger and I think a small steel ball in there.

Be very careful, these extractors are hard to find. Breaking this extractor's edge by pushing too hard could be disastrous. 

I concur with the need for cleaning, even ultrasound cleaning of the entire bolt assembly to start. If no ultrasound, then boil the bolt for a time to get the grease to flow.

My SAKO L461 came with a lot of factory grease like cosmoline or RPG in the entire bolt assembly. It was slightly used and never thoroughly cleaned.

I want to thank everybody who chipped in suggestions for fixing my extractor problem. I tried them all including almost convincing myself that I should modify the angle on the face of the extractor that forces the extractor over case rims before I came to my senses and decided that if the Finns could make a rifle as perfect as the L-461 then they probably knew more about the right angle than I did.

The last thing I tried was Bud's suggestion to take the bolt apart and boil it in case the heavy protective grease it was shipped with has deteriorated over the 55 years I have had it and gummed up the extractor. Bingo! It now works slick as could be.  Congratulations Bud. You hit it on the head.

about 2 years ago i went to 0-30 mobil 1 synthetic motor oil for all my gun uses ... except ballistol for quick wipe-off of steel and wood stock ... and Fluid Film for severe duty long term storage.  so far so good, no gumming.  i had a ruger 77 push ejector gum-stick on rem-oil before.  mobil 1 zero-x wt is slightly thick but doesn't get worse.

for guns that get cruddy ( my 22rf autos ) i clean with WD40, then re-oil .

Good idea Ken since the extractor has already proven that a bit of gum with very little clearance can cause trouble.  I have used it for years in the shop and brought a can from Maine.  Now, where in the heck is it.
