You can see the little line right above the reflection and just below the shoulder, the right hand side of the nick just touches the shoulder. It is a little nick that you can just feel with your fingernail.
Is this from the tool when they chambered the rifle? It is a pre-chambered barrel from Pac-nor. It shoots great, I was just curious if they did something when they were chambering it that they shouldn't have (stopping the machine without backing the reamer out or something?
On the bright side, I can tell how many times each of my brass has been shot
AJ is the rifle a center feed or a staggered feed ?
It may be from the mag or it could be from hitting something on ejection.
Place a new loaded round in the chamber with out placing it in the mag and fire it then remove
it very carefully with out letting it eject and examine it if the mark is there then it almost has to be something in the chamber.
If you have the reamer very carefully insert it into the chamber and using a 1/2" socket extension
backwards very slowly turn the reamer (Do not use any pressure on the reamer) all you want
to do is remove any thing that is there and nothing else.
If the round comes out without any marks when removed slowly and with out ejection then
place it in the magazine and feed it in and then extract it slowly and examine it for the mark/scratch if it is still not there then in the process of ejection it is hitting something (Normally
the scope base or part of the ring.
I hope this makes sense and you can find what is causing it.
Any defect caused by the reamer are normally circumferential and not in this location.
