Looks like a fairly major imprint where there shouldn't be any, to be fair as soon as the bolt handle mooves the case should be free and the rotation of the bolt should take the case with it. How many fired cases do you see with scraps and gouges in the case head from where the extractor has been pressed into the brass?
That scratch could be enough to prevent the case from rotating with the bolt head which could in turn give you massive extraction issues as the case just doesn't want to 'pop' free of the chamber walls. I suspect from my experience you are past primary extraction point without the case coming free from the point at where it's pinched...
