Ruger Bolt question

[FinsnFur]

I know I've cried about this before on here, but I can't find the thread so I'll make a new one.

I'm still battling the bolt on my Ruger all weather M77 MarkII 22-250, it just does not want to consistently eject the shell, and if I remember right, it's done this since it was new.
And it really sucks to have to tip the gun sideways and shake the shell out of it, when your out there

For the longest time I signed it off as being an issue with the cartridges, but I've tried practically all of them, and it doesn't do it all the time. Maybe 90% of the time though

Rick223 had it all apart. He read somewhere that Ruger's factory grease can cause this. But after putting it all back together, that didn't seem to help either.
Now were wondering if it's the gap between the ejector and the lip that's at the base of a shell. (Pictured below)







Anyone got a Ruger centerfire bolt action , they'd be willing to pull the bolt on and check theirs for me? Were wondering if the ejector should be riding on the shells shoulder.

Mine does .

Yeahs sumptin dont look right with that. Maybe call the factory and Bark.

A few thoughts and suggestions:

1. Check for dirt or hard grease in the slot the ejector passes through. Most times a really good cleaning solves the problem. Dirt or gunk can slow or stop the ejector from moving freely. One sign is when the ejector works when the bolt is moved slowly, but sometimes fails when rapidly worked. Thick grease and gunk in the ejector slot may slow things enough so the ejector doesn't have time to move outward when the bolt is worked fast.

2. Check the tension on the extractor. Place an empty case against the bolt face, the extractor should move a bit to the right if viewed from above. If that is the culprit (not enough tension) you can increase the tension by slightly bending the extractor away from the bolt body (about half way from the collar to the tail end).

3. Are the cases hitting the inside of the receiver bridge as they exit the ejection port? If so, a trip back to Ruger or your gunsmith to smooth the upper corner off the right bolt lug race may solve your problem.

4. Call up Ruger and see what they say. They may have you box it up and send it to them or an authorized repair facility.

^^^ Good advice, FOsteology  

Mr. Jim,

This may help… Here’s an exploded view of your Ruger action:


Part #8: Ejector
Part #9: Ejector pivot pin
Part #10: Ejector spring
Part# 11: Extractor
Part 12 : Extractor band

Well.... You could also be short stroking your bolt.  

For Mauser type actions like your Ruger try this quick test to see if the case ejects like it should... Load a dummy round or spent cartridge case in the chamber (for safety sake). Work the bolt back quickly and firmly until it contacts the bolt stop (be firm , you won’t hurt your rifle). Did it eject?

I have several M77 actions but they are older........ and they all work fine.........  Try sending those pics to the factory and see what happens....... they are very helpful on such matters.....

You got me lost Fos. I dont see how the extractor can be bent slightly to hold the case tighter, when there's no play available to allow it to move closer towards the center of the bolt.

The last pic up there even shows the extractor tight against the bolt in the groove thats right below my arrow.

Tried checking the clearance and it's almost as if the extractor isnt even on the bolt, The minute the bolt is opened the round is let loose. In fact I can point the rifle upwards, and open the bolt and the shell loosely rides on top of the bolt.

Chet, that same diagram is in the rifles handbook.
Tried your test Chet, and the shell just pukes loose the minute the bolt is opened.

Good idea

I need a picture of another Ruger bolt face. I'm beginning to wonder if maybe my ejector is deformed.
Been searching Google and cant find anything...yet.

I could send you mine and you could take a pic .  I tried and we can all guess what it looks like.

YES......... There is something wrong........... I wish my camera was working........ Mine is MUCH tighter than that.  I checked it and you should contact the manufacture or a gun smith.

Jim what is your camera?  How big is the LCD screen?  I got's to try something different than what I'm doing.

[FinsnFur]

My camera is a Canon SD1400 and the screen is 2" x 2 1/2"

You should be able to rest the camera on something to hold it still Barry and take a fairly decent close up.

[pitw]

Jim I've took fifty pics that didn't turn out.  I've also took a few hundred of another gun to get VV's opinion on it but I suck .

[FinsnFur]

What kind of camera you using? I thought you had one like me.

[vvarmitr]

Just go ahead & show me the pix Barry. I won't notice the difference. I don't see that well anyways.

[vvarmitr]

For closeups Barry I put the setting on "M"  for Macro.
That's what I use for pix of fungi a lot.

[slagmaker]

Barry, you need to set the camera in "macro mode". If you have a tripod mounting it to it would be nice. Even a tripod that came with a spotting scope would work. Macro will let you take a pic of soemthign about a foot from the camera and it will be in focus.

Set your camera to macro, it will be a button that looks like a flower, then get everything set up and use the self timer to take the picture. This eleminates shake and bluryness.

[pitw]

Thanks slag and all.  I been shaking since I saw the light and it never has helped pic quality.  I'll be trying these things out in the near future .

[FinsnFur]

Barry, If you havent tried it, maybe try putting the camera into macro mode which will be indicated by a little flower icon. That should let you take a close up pic.
