View Full Version : Remington 700 extraction problem

I have a new,(40 rounds) Remington model 700 classic with an extraction issue. When closing the bolt it strips small pieces of bras from the rear of the case. Every four or five rounds there is enough of these small pieces that it fouls the ejector pin while the cartridge is in the chamber and as a result will not eject the round.Pushing the ejector pin up and down with and ink pen a couple of times free the brass and allows the ejector to work again. I e-mailed Remington with the problem and of course they said take it to a repair center. The nearest on is not near. I have looked for rough spots or burrs that might be cutting the brass and could see nothing. I have flushed the bolt and got no residue. Has any one encountered this problem. If so, what was the fix?

I have had the same problem but it was with a semi auto mini 14 the ramp up was so sharp it was shaving all my shells down when they went into the chamber I had to take and file it down to a rounded edge took a while but that is what I had to do I would at least get the opinion of a gun smith first befor you go filing a way hope that helps some.

Where exactly is the brass being shaved? The case body as it is being forced into the chamber? If that is all it is a very careful polishing of the chamber entrance is all that is needed. Sometimes when reaming the chamber it can leave a very sharp edge there. On my 7mm STW Sendero the chamber edge was shaving brass off it also, not as bad as yours, but bad enough to leave chatter marks on the brass. I polished it (just the edge at the entrance of the chamber, not inside the chamber) with a bit of 600 grit wet dry. I mean I just barely buffed the entrance, just enough to break the sharp edge. Problem gone. 4/0 (0000) steel wool would probably be a better item to use. It was a real pain getting the paper over my finger and then my finger in there for a little twisting action.

The brass is being shaved on the bottom, often almost removing the logo. I have done everything I can think of to find a sharp spot on the bolt face. I can't feel anything. I even ran a q-tip across it to see if it would grab any of the cotton. It almost looks like the extractor pin itself is doing the scraping. The marks line up with it and on a couple of the cases the round shape of the extractor pin can be seen at the end of the scrapes. The pin however is smooth. I called the nearest Remington repair center and the gunsmith that I talked to offered nothing other than he had not seen the issue before.

Dean just because you can't see or feel that it is sharp don't mean that it is and I don't get how the extractor pin would shave the shell on the bottom when you are loading it into the gun the only thing that would hit it would be the ramp just barely or lightly smooth off the edge and see if it is still doing it.

Dean sorry I was miss reading I thought it was coming from the side of the casing not the bottom of the casing maybe the bolt is slightly grabbing the case before it is allighned with the bore and causing a slight jam between the bolt and the bore and it is making the bolt scare the bottom of the caseing put a round in the gun and pull it back out and see what the bullet looks like to see if it is jamming a little.
I think what Mr. Fay is saying (correct me if wrong) is that it appears the ejector pin is sticking when loading a round into the chamber and when the bolt is turned to lock it, the pin is gouging brass off the cartridge base as the bolt turns.
Here, the only solution I can think of is to disassemble the ejector, make sure there's nothing in the pin recess and spring that would cause it to bind and fail to retract and that the head of the pin has no sharp burr on it to hinder retraction or to gouge the cartridge base. Working the pin with a ballpoint pen or other means which allows for proper function firing a couple rounds and then hanging up again would seem to indicate there's something internally in the pin recess causing it to freeze up.

Hold on a minute! What it sounds like is brass flowing into the ejector cut. (The extractor is the small clip that slips over the rim, the ejector is the plunger-type pin) If you are seeing a bright circle with the headstamp rubbed off, you have brass flow. THIS COULD BE AN INDICATOR OF VERY HIGH PRESSURE! It could be soft brass, as well.
Do a couple of things to diagnose the problem. First, are you firing handloads or factory loads? Factory loads that do this are almost certainly a sign of soft brass - try a different brand or lot number. If handloads, BACK OFF and try different lot of brass, too.
A quick experiment is to chamber a fresh round without firing it, then eject it and inspect it. If you do not see the "scrape" on the unfired brass, you are having brass flow upon firing and you NEED to find out why. It's a potentially dangerous situation. Let us know what you find out.

Dean,
Did you figure anything out on this? I'm curious!

In agreement with IDShooter, I had a very similar incident with one of my Rem 700's, this one in 7Mag. I was working up elk hunting loads 2 years ago consisting of 160gr Part and H4831. At some charge level I started experiencing a problem with ejection, ie none! I noticed also that the case heads had shiney marks on them almost obliterating the head stamp. The ejector button was completely fouled up with brass and was stuck (in). Bouncing the pin with a small punch worked the brass out from around the button. These loads were way too hot! All I can say is thank goodness for strong actions. These symptoms started completely without notice, at least that I could detect.
Sound familiar? Are you handloading? If so what's your load?

Yup, if coming off the head like that it sure sounds like HP to me also. Are you shooting factory loads? Something sure doesn't make since unless they are handloads with something very, very, wrong.

One dumb question: Is this new brass or old brass? When you seat the bolt forward does it bind before you lock the bolt? Maybe the brass is too long (used) and your putting too much pressure on the bolt when you close it? :confused:

It took a lot of thinking and reading all of your posts. It was not a rifle issue. The brass that was shaving off and jamming the ejector pin was Federal factory loads. The new brass arrived on Friday and I reloaded several different loads and headed to the range. The hand loads worked fine. That lead me to start comparing the brass. The final result was that the federal brss,(the one causing the issue) measured .041 thickness on the brass rim and the new brass measured .037 at the same place. The only conclusion that I can come to is that the bolt was simply shaving the brass because it was too thick. The handloads also chamber much easier,( less pressure on the bolt handle) than the factory loads.
Thanks for all of your comments. If you have more post them. I will be sure to check back.
