Pressure or not?

I've been handloading for 30+ years but this I need some help with. This is near max powder but my coal is longer than book obviously. This is a Tikka 308 Win and I understand this is 7.62x51 brass and I have taken that into account. It's actually made by Naamo which is Lapua so this has been very consistent brass. OKAY on to my question….. Does this look like over pressure or a scrape? It appears to be from the cutout for the extractor and I don't see any ejector swipes. I haven't chronoed it yet I was trying to find my pressure limit. No sticky bolt lift.

Thanks

Doesn't exactly look like classic ejector swipe. Use a punch and check to make sure the ejector can be pushed flush or slightly below the bolt face. Sometimes enough crud can build up in the ejector hole to cause the ejector to sit proud. As long as you're not experiencing heavy bolt lift, I wouldn't suspect over pressure.
 
hard to tell if it's a scrape with all those bandages on

looks like you've got brass under your extractor, maybe the nipple on the ejector plunger is digging in and gouging right there on the case.
