I didn’t see any pressure signs on the case, but there were gouge marks on the bottom, I guess from the ejector? I’m not sure what would cause that. Higher pressure?
Pressure signs typically show up on the head/base of the cartridge, not the neck or sidewalls. Yes, those gouge marks are indication of high chamber pressure often referred to as swipes. They occur when the chamber pressure is high enough to push/reform the brass back into the crevasse of the bolt, in this situation the ejector pin. Looks like there are extractor marks, also. Your primers are flat, too. Is there a "crater" around the primer strike, e.g., a lip that you can catch or feel with your finger nail.

Swipes usually occur when the bolt rotates to open. These marks don't seem to have much of a rotation indication with them. If they had, the gouge marks would have been sheared off and not be raised above the case head.

Did you bolt lock fully back with these, e.g., on the face of the bolt, not the lip of the bolt carrier?

There is a very slight lip on the primer that I can catch with my nail. As far as the bolt locking back, I didn’t notice if it was on the carrier or the face of the bolt.

I finally got around to testing these out. Overall they shot very well. I didn’t see any pressure signs on the case, but there were gouge marks on the bottom, I guess from the ejector? I’m not sure what would cause that. Higher pressure? View attachment 63601 View attachment 63602
Yeah, those are swipes. Ive seen some light swipes on a couple of my rounds, nothing that pronounced. Which barrel do you have again?

Shot these through 4 different rifles. Pressure signs were different in each. The 110 ph top, 90gd middle, 100nosler bottom.

Definitely pressure signs: craters around the primer strikes, plenty of swipes, and multiple instances of carbon blow-by around the primers.
