Not sure about the longitudinal “scratches” but could be normal as brass stretches out eg on the initial firing from Saami min to your chambr.
I myself would just keep using them till a definite groove becomes visible on the outside or they separate.

My understanding is that a case separation like this is not particularly dangerous. I had more than a dozen do it in my 303 and never noticed until I went to eject them. Not sure what it does for target level accuracy. Will be interested to hear others’ opinions on the safety aspect.

0.002” sizing per shot is pretty good.

If you are going to consistently cull brass on the basis of shiny rings or paper clip feelings you will be Lapua’s best friend.

I disagree, the paper clip method is quite sensitive. You can feel the change over the surface, the ring mark seen from the outside is also detectable on the worst ones with a thumbnail as well. I would like to put my borescope down and have a looksie inside the case.
But will save that for another day. Work beckons....
