Sharp extractor, marks on case head, how to fix?

[BCP]

One of my ARs has a sharp extractor, okay with some brass not so much with others. Example, the LC cases were 24TAC and a 75gr hornady while the WCC were 23.6 and a 69nosler. As you can see it's a lot harder on the WCC than LC even though it's a lighter load with a lighter bullet:

It's not your extractor, it's the extractor cut on your bolt face and the ejector hole in the boltface....

Thanks, I tried the above suggestion and it worked. No more marks on the case heads that I can find.
