Need Help - case neck bump after firing

[Jake&Ruger]

All of my once fired brass have an identical marking on the case neck. Same mark between hand loads & factory ammo. I'm guessing there's a groove in my chamber that the brass expands into. Do I need to worry when relaoding my brass? Rifle is a savage axis 308.

Thank you.

You probably have a burr in there from chambering.

 

[Jake&Ruger]

Should have noted this deformation is raised. Which makes me think there's a gouge in the chamber not sure how I'd even fix that since that. This rifle hasn't even had 100 rounds through it. All where corelock remington or plastic tipped copper. My biggest question is will this compromise my brass for reloading? I use SRP 308 brass from peterson and really don't want them to be a one and done.

All the major firearm manufactuers in the U.S. are very commited to backing their products. I would reach out to the manufacturer and ask for assistance. My bet is they will ask you to return it and they either repair or replace at no charge . In my mind other than the hassle it is no big deal and you will be taken care of.

Yes it will affect your brass. Send it back.

Take it to your dealer and have the chamber scoped. Fine Firearms in La Mesa offers this service. This will determine what your next step is.

As far as the brass is concerned, lube it and run it through a full length resize die and see what it looks like. I am guessing it will be fine.

Thanks for all the suggestions everyone. The rifle was bought close to 10 years ago and just never used it much. I recently overhauled it with a new stock & scope. Pretty bummed I didn't notice this until after I completed the build. It's my only appropriate rifle for deer season so it looks like I'm kinda stuck for the next month. Here's a picture of one of my SRP brass after a full length resize.

Post full length resize

A cheap Teslong boresope on amazon will get this done and more. They are great value and work well.

$50 to $175 ish.

I would take up NBK suggestion , a reamer for the chamber might fix it. It will depend on chamber length. If It is all ready at max chamber length. May be it time to
Park it.

Update: bore scope shows the void in the metal clear as day. There's a second void in shoulder but the larger is a dead ringer for the raised marking on my brass. The two voids seem to be 180° from each other. Doesn't look like a tool mark to me though with the rounded edges. Also does the pitting in the barrels metal look normal? Can't say I've ever scoped a barrel before so this is all new to me.

 

[Ofdscooby]

New barrel toss it.

Pitting is from rust. Run a patch of Mobil 1 oil through it when your done cleaning

I would have reservations about shooting with that pitting.

 

[Bowman]

It hard to say why the pitting.
But as said before corrosion is a possibility. Pitting in my line of work is a bad. It can be an area of Crack propagation. In my line of work pitting is generally from contact stress on the surface. It is a sign of failure.
Buy a new rifle. And put the old rifle on a rack

+1.

I spoke with savage customer service then other day and they said it may still be eligible for repair/replacement if deemed a manufacturer defect even though the rifle was bought 10 years ago. It's seems pretty clear to me the chamber shoulder is not from corrosion, rust or misuse on my end considering the shear lack of rounds through the gun. I'm also wondering if the pitting is also from just bad metal. This gun was always cleaned & oiled after the limited use it's had.

The third picture looks like it is in the lands and grooves which indicates basic erosion from firing. Erosion starts from the first round being fired and degrades from there.
