I recently purchased a sendero II in 7mm rem mag. I had it for a month before actually firing the rifle to find out the the cases Jam in the chamber once fired. Im trying to resolve this at home before sending it away So anything to check or do at home would be of great help as hunting season is just around the corner and I would rather not send it away.
So story is, after every round I fired they would get stuck the bolt handle would move up and down but wont pull back. This is both with federal premium nosler partitions and cheap winchester super X. I had to remove the cases with the cleaning rod down the barrel this done it with about 10 round and never got better. So brought it home cleaned it well brought it back out and the first 2 shot fired everything worked they ejected perfectly then the 3rd jammed up again Im thinking the lubrication that was left behind made the 2 eject perfectly. brought it home tried to find a burr in the chamber or anything visual cant see anything with the naked eye put a couple tools down the chamber to see if I can find this "burr" with no luck.
Now all the spent casings have a shiny ring around the case and light scratch marks once extracted, which indicate the "high spot" in the chamber. Any home remedies or no use and I gotta send it out?
 
That's crappy.

I recently bought one on here too that seems to have "tight" neck but it extracts fine.

Who knows with Remington's nowadays....their quality is about the same as any...some times o.k sometimes crap!

It's a terrible shame what they have done to this companies once fine reputation....

It probably got its chamber cut with a worn out reamer that did a few 1000 barrels....

Send it back for warranty otherwise your gonna have to get a gunsmith run a reamer in it.
 
I had a Remington 700 SPS in 300 Win Mag and the chamber was rough, I cut my finger when I felt it and the bolt was scraped down because of me opening and closing the bolt
 
if you can get a chamber cast done ,if it won't come out then there is an irregularity in chamber .Use a heat gun melt out cerrosafe ,clean and send for repair
 
Just an update I Know it's been awhile, but it went out for warranty twice. First time I got it back no more jammed cases but still evidence of a "burr" as it still showed a light scratch mark after fired but no issues with ejection. I couldn't get it to group at all with different ammo so I contacted warranty and sent it out a second time, the final outcome was they replaced the rifle as they also couldn't get it to group. It was purchased on cosignment bnib from a sponsor I'm not here to bash anyone but wasn't to happy how they told me to go through warranty and it's been a long process to get it all figured out. On the other hand it was on consignment so it's out of there hands I think the previous owner knew of the issue and tried to dump it
 
Almost everyone expects if there is a problem covered by warranty who ever sold them the rifle should replace it... but the manufacturers who offer the warranty have specific terms. It is usually the owners responsibility to get it to a warranty station, not just to return it to a store.

Glad you eventually got this sorted out. Kind of crappy the original owner didn't sort it out.
 
Gravel Agency do the repairs for Remington. They're okay to deal with, very responsive at least. They've had one of my guns for a couple months now, waiting on parts from Remington...
 
Gravel was good no issues great communication like I said not trying to bash any company just hoping that someone in my situation can dig up this thread in the future and see the process/outcome (that's why I gave an update post)
I called before I purchased this rifle as they had 2 senderos brought in by the same guy and both were suppose to be bnib I know the other guy who bought the other one and his has the same exact issue hence why I mentioned the previous owner was trying to dump these rifles on someone else.
Anyways the outcome was good it just tooK awhile to resolve
 
Your rifle has no primary extraction because the bolt handle is in the wrong place. In addition, the chamber may be slightly burred ahead of the belt recess.

As above
And

Clean the bore & chamber thoroughly,cleaner than never fired.
Fire a factory round
Clean the bore & chamber thoroughly
punch out the primer in the factory brass
drill & tap the primer pocket to 1/4-28tpi
thread an 18" length of All Thread w/ a jam nut into the tapped primer pocket/tighten the jam nut to the head of the case.
apply 250-400 grit lapping compound on the case just forward of where you witness any abnormalities
chuck the all thread into a drill motor chuck
polish the chamber out
clean the bore & chamber thoroughly
fire another factory round
inspect case for abnormalities
done

depending on rifle vintage
your bolt handle is either 1/16 to 3/16 out of TIME for Primary Extraction.
 
If one wants to remove a burr at the front of the belt recess (the most common flaw) he is as well off to simply use a split dowel with a strip of crocus cloth or 600 grit wet or dry paper and a scotch brite backing. Lapping with a fired case isn't that efficacious and might even perpetuate a flaw. Regardless of the method used, less is more and polishing should be minimal. If the chamber is so flawed as to need a lot of polishing it's too messed up, period. I really think, in a case like this, the barrel should be pulled and checked out while the bolt handle problem is being addressed.
 
If one were to polish the chamber it is best done with the barrel removed. 400 grit wet/dry paper would be the coarsest I would use... and not for long with lots of in and out, less rotational in one spot. I think compound on a case spun in a chamber easily lends itself to polishing everything deeper, flaws included.

This fix is best left for the experienced.
 
Dennis is right (and why would he not be?). Polishing a chamber with the barrel on the receiver is a jackleg approach to a repair. With the barrel removed, flaws are easily seen and addressed. By the way, I have had success using a fine ball hone for this sort of thing. Again, minimal time spent and never dwell in one place. When dealing with a new chamber, I agree with those who say, if it needs much in the way of polishing, the chamber was screwed up in the first place. There should be no significant toolmarks or burrs.
In a belted magnum chamber, the slight burr at the front of the belt recess can be left behind depending on the design, condition, and use of the chambering reamer. It is not uncommon; especially in Remington rifles. Make of that what you will. The mystery remains, if every rifle is proof tested, how can the people at the plant possibly not catch such things as a burred chamber or a rifle with zero primary extraction. A proof load is hot enough that it would have to stick. My conclusion? Not every rifle is proof tested; whether at the Remington plant or many others. I have seen several Winchester rifles which would not even come close to accepting a factory cartridge. One rifle, plainly, did not have a finished chamber. Yet, it had a proofmark stamped on the barrel. One Reminton 700, in 300 Win Mag, had enough of a burr ahead of the belt recess that it was impossible to chamber a cartridge. Was this rifle proof-tested? I can't imagine how it could have been.
 
Sorry to hear about your medical problems. Getting old is not a lot of fun and I am experiencing a lot of problems especially since I turned 81 recently. Sure does affect my shooting fun and excursions to my gun club. Take care and hopefully nothing more serious develops.
Not sure if you have been following my thread on the Browning Auto 5 barrel exchange, (3inch barrel on a 2 34 inch gun, ) but I am sure you have encountered this before. I would appreciated your input. Thanks in advance, Jack
 
Hi,
I bought this exact same model a few months via the E E Forum & I've not
yet fired mine. Did your'e rifle come to you via another forum member ? I'm just hoping there's Not a bad batch flying around out there!!!!!

Just wondering!
Thanx

It depends a little on where you live. In Saskatchewan a dealer of anything is automatically on the hook for handling warranty claims whether he likes it or not.
