Also, there are scratches on the outside of the extractor land.
Do I have major problems? The scratches are very evident.
Try single loading (Lay one round in the action and push it in as far in the chamber as you
can with your thumb and close the bolt on it).
This will tell you if you have a sharp edge that is scratching the brass during the magazine
feeding process .
This is most likely the problem and can be fixed .
The staggered feeds are notorous about this .I have switched almost all of my rifles to a
center feed mag box to stop marking up my brass and the bullets.
