Sako 85 extractor/ ejection issue

They can, if they break. I've had this happen twice with SAKO rifles from the .70s and early 80s. The ejector in these is combined with the bolt-retaining catch - so a problem in two ways.

Haven’t had chance yet, it’ll have to wait till next week, london, Salford then down to Brecon for some pike fly fishing over the weekend….
I’ll keep people posted and take photos if I find what it is

It happen to my 85 in 308 I found dust like brass has gummed the plunger after I stripped it all down and over a cloth then slowly to catch the spring etc and blasted it with carb cleaner the crud flowed out and all was good with a light oil.
(from sako) You can remove the extractor by depressing it at the rear and finessing it out of its seat. With the long extractor, you might be able to straighten it and reuse it. Be careful not to lose the little spring and plunger that hold it in place.

Hi there, so I finally had time tonight to get the rifle out and have a good look at the issue….. there was nowt wrong with the bolt face, but I noticed the ejector ‘pin’ wasn’t riding up into the slot underneath the bolt face…. The bolt travelling backwards engages with the spring loaded pin of the extractor and it’s the bolt carrying the case backwards to the sprung pin which is fixed into the action that launches the spent case out of the action….. from the photos it was clear that the groove underneath the bolt face was a bit ‘cruddy’ also the travel of the extractor upward was being ‘impeded’ meaning the rim of the case never made contact with the pin and traveled ‘over it’…..
The springs seemed to be ok, but the lack of travel was obvious ( see pic with orange arrow). Now at this point I thought ‘stock off the action, strip down, clean, reassemble, re-zero and ta-da…’ . But I want to go stalking on Sunday morning and the time to do this was doubtful…..
So I cleaned the crud out of the groove and sprayed some silicon oil onto the ejector mechanism…. A bit of a wiggle and the ejector was travelling back nicely into the groove under the bolt face to make contact with the case rim- cases ejecting nicely….. see photo with pink arrow.
I’ll keep my eye on it, it doesn’t make the rifle unsafe and the only downside is it slows a follow up shot ( you need to pick out the unejected case). But so far so good……
It must have been either a bit of build up of oil/ soot/ crud…. Or a small piece of grit/ brass swarf?

The ejector is spring loaded and forced upwards by two small springs in captive pockets under the extractor loaded by the base of the action
If the ejector isn’t free enough to ride up immediately into the small slot in the base if the bolt ejection will be compromised
Dirt, moisture and general lack of maintainence will cause the bearing surfaces to clock up or rust slowly causing the mechanism to stop working properly

I’m betting on dirt. Anyhow a good spray got it clear….
Not too much lube though. It will gunge up.

Not if I’d got to take the stock off…. Then I’d have to re-zero??

An aside here, and I think I may have posted this before. A bloke in Queensland, Oz had this ejection problem on his '85. Can't remember the calibre or chambering. He found that the extractor claw was not holding the case tight enough against the bolt face. Being a machinist by trade he made a new one with a much tighter tolerance. Issue resolved!

To be fair - I’d never want to remove and replace a stock without at least checking zero with a control shot. Shouldn’t move zero, but….

I don’t think so… the stock and how it’s tensioned to the action could have an effect on the point of impact…. Something I’d not be happy with unless I had chance to put a few rounds down range…. Which I’ve not got time to do.
Whilst there’s no doubt a strip and clean, oil and reassemble is the ‘proper job’ I’ll only do that if it happens again….

But it was pretty with its stainless finish and fluted barrel!
How many mistakes start!
