700 Bolt Extraction Problem

[Muddyboots]

So my .270 Win build from hell is now twisting me up. I put it all together and was waiting for triggerguard screws. I swiped some from another rifle and decided to do a test feed which I should have done right after headspacing last week but did not. No clue why I didn't. So I load up the COAL I am going to use and it fed perfectly and bolt closed perfectly but will not extract any case I use. Double checked headspace and perfect.

I had the receiver trued up, lugs and whole nine yards done by a reputable gunsmith that I trust very much.

Fire control works fine, cocks, fires and safety works fine.

So what simple thing am I missing here to fix this extraction? I can place a round into the bolt head and it will grab it and hold it for extraction. I have built 3 other 700's and never had this problem before. I know what is probably the cause but I am hoping otherwise so hoping someone will provide a solution that I don't want to address with action.

Is the counter bore done correctly?

When you use the GO and NO-GO gauges do they get attached under the extractor?

 

[Muddyboots]

No, but I did not have the firing pin in bolt which is my normal method of setting headspace to have best feel. That would have been my first oh oh if I had left the firing pin in bolt. I don't like taking chance of doing something dumb like pulling trigger with gauge in chamber.

I did try afterwards since I wanted to double check headspace no they did not extract either.

Have you tried some new brass? The only time I've ever had extraction problems in my Remington 700's was when I fired some brass in them that had been shot in my Ruger#1.I never had any issues before using the same brass in multiple rifles,but I definitely have to keep the brass used in the Ruger separate.Full length resizing wouldn't correct the problem.The only thing I could think it was is,the cases were sticking in the Remington chamber below the base of the sizing die.Switched back to brass that had not been fired in the Ruger and I never have had an extraction problem again.

it fed perfectly and bolt closed perfectly but will not extract any case I use.

I'm not clear on whether the failure to extract is loaded/unfired, or after firing, or both...

If you place a round in the bolthead, feed/put in battery, then try to extract the round is it still retained by the bolthead?

I had the receiver trued up, lugs and whole nine yards done by a reputable gunsmith that I trust very much.

Then, this is probably on him.
What exactly, did he do to the action? If he trued the lugs and receiver abutments, you lost some primary extraction. How much, depends on the amount of material removed from the lug faces and abutments. If it was borderline to begin with, and he faced lugs and abutments the bolt handle probably needed to be re-timed.

Did you call the smith? This should be your first step...
Call me crazy; I never send out a barreling job without test-firing, and a function check. Was this a new receiver? If it was not, what was it's history?

yep tried new brass both Hornady and Sig Sauer. BUT I believe I found the problem. This bolt face has the floating spring snap in ejector. It seems to be boogered up and seems to not want to stay in place..I am hoping this is the simple fix and not lugs.

tobnpr: This was a used rifle I bought and tore down for a build. I knew nothing of the history and it was a roll of the dice I took. I could not test anything since it was on line buy which is a lottery ticket chance that looks like it may be a losing ticket. I did the rebarreling which I have done many times before without incident and this was first time I ran into this issue. Maybe just lucky? The first thought I have is exactly your thought as well that it was borderline to start and any material removal took it off line.

I sent him an email today and he called me within an hour of the email sent so he wants me to send it back to him which I will do. I was posting up just in case I was missing something else.

It sounds like the extractor is jacked up.

 

[Muddyboots]

I hope but I really think now that this bolt was worked on before and now I have lost primary extraction. Learning experience and sometimes $$$$$.

My first thought was you might have a broken ejector - not missing completely, but enough that it won't extract. I broke one on a Stiller actioned Lapua because I accidentally fed the wrong load (from a different Lapua).

90% of the time Rem 700s have little or no primary extraction. New or older, doesn't seem to matter. It's like the factory didn't understand Walkers' design. "Slap that handle on there and braze it", seems to be their motto.

 

[dfanonymous]

That part of primary extraction has to do with the caming. The OP hasn't made clear if there is no extraction unfired, fired or both. If fired then caming might be a problem. If unfired then the extractor is probably outside the tolerance after the gunsmith dicked around in there. Especially if it's a riveted extractor. I'm curious if the bolt face was squared too. That would mean the extractor was taken off…I would hope. In which case that would be the gunsmiths fault.

This is a new build on an older 700 action that I bought as a rifle that I tore down. This was the infamous barrel won't come off thread. I never got to fire it so the extraction problem ONLY started when I tried a feed test for the COAL that I am going to shoot. The ONLY thing the gunsmith did for me was to true up the action, lap the lugs, square the face pretty much standard action trueing. I put the rifle together and that is when I found no extraction. Whether I fire it or not, I should have extraction.

Pretty sure now where the issue is from a very basic test. I pulled a bolt from my son's 06 and placed MY bolt in his rifle. I was able to extract a fireformed case properly and easily in his rifle with MY bolt. So much for ejector being an issue.

When I placed his bolt in my action, it would NOT extract the case. So I now believe where the problem is going forward as suggested by tobnpr in #6.

End of the day, I broke some personal rules on buying used without holding it, cycling it, knowing what was done before on it and so on. For all I know, the action was trued up before and material was removed from lugs and abutment. Painful costly lesson learned and not sure what to do next. I will call the GS tomorrow morning to discuss next steps.

So basically, I now have a (in)complete rifle without an action! Scope is mounted, leveled, level added, so just a royal PITA going forward. Heck I even have 40 rounds ready for break in, 20 with Hornady brass and 20 with Sig brass to do basic fire form and testing of velocity/pressure against each other with same load.

Just mad at myself right now. Hopefully someone will learn from my dumb mistake.

Thanks for the input.
