Home Forums Hunting & Shooting Gunsmithing Crooked chamber ??

You can roll the dice some more and buy one of the nutted prefit bubble packed barrels......

I appreciate your suggestion Al but for now since it will do 2" at 100 I will just work with it. If at some point in the future I win the lotto or have way too much money just laying around it can stay like it is. Although the .358 suggestion has some real merit to it.

What does your fired brass look like? Does it have the characteristic Remington bulge on one side just above the case head? Just curious.

I have to tell you ruffcut, I haven't looked. I will find some I recently shot but have not yet resized and get back with you.

Hello ruffcut
I just checked some once fired brass I kept back from a January hog hunt. I do see a bulge but as I measure it, it's only about 2 or 3 thousands of an inch taller than the surrounding brass. It left more of a scuff than a bulge.

I’ve had a couple R700’s where a bulge was quite noticeable. I assumed it was that the chamber wasn’t square with the bore but the case head was supported by the bolt which the lugs kept the bolt in line with the bore.

As you can see from my pictures the lands are uneven. Since that is in the throat and not at the bolt end of the rifle I don't see how that would create a bulge at the bolt end; but, a guy never knows. It's my guess that the bolt end of the chamber is a bit oblong or not a perfect circle in some manner. It is a Walmart rifle so I suspect they did not get the best rifles. IN some manner they were seconds and not firsts.

Thanks for the heads up. I will watch for the "bulge" should I ever get another Remington. If I could ever find a logical reason, I would get a .270. I just can't justify it since there is nothing in Iowa I can use it for except coyotes.

A few T/C barrels had crooked chambers, Mike Bellm used to take an example to gun shows. He thought T/C chambered using a drill press, he uses a lathe for his chambering.

The buldge isn't because the chamber is at an angle to the chamber per say. It is because the reamer was not on center when it plunged and therefore cut more on one side which make the chamber oversized on the head end.

308 to 358 would be dependent upon how the bore squared up after the rebore and how oversized the chamber is now.

I see no real fix without shortening the barrel at the chamber end and recutting a new chamber. Maybe someday when there is more money laying around I would consider that. At 2" at 100 yards I can live with it as long as I'm not using it for shooting at prairie dogs with light bullets it will have to do for now. I see where Walmart can sell these rifles so much cheaper than everyone else. It appears they get 2nd's or maybe even 3rd's with barrels that are less than perfect.

Hopefully the new Remington is a bit more careful with their finished product than the old Remington.

The bulge is because the brass is on the small side (almost always) and the unfired shell is pushed to one side by the extractor. In addition the brass may be thicker on one side so expansion takes place opposite. GD

If only that were true that the bolt lugs line things up.....actually the sear holds the back of the bolt up and misaligns the whole mess. Couple that with a slightly oversized chamber and you get the "Remington bulge". If you really want to prove this, next time you chamber a rifle put the bolt in a lathe and dial it up. Cut the back of the lugs {light skim cut} and then lightly lap them........
I don't know how you cut a crooked chamber, but I sure see a lot of Remington 700's and Seven's come into my shop with this issue. They will give you a new barrel if you send it to a repair center. It was suggested to me some time ago that they are cutting chambers with a CNC boring bar, ut I still don't see how you could get it crooked. I have purposely tried on a cut off junk barrel and I cannot get the rifling to look like many Remington's. M
