"I do see round marks from both the Remington and Winchester brass from the pressure gauge."
I see a couple issues with this statement.
1. You are using mixed headstamp brass. In my opinion, not a good thing for consistency. I NEVER mix headstamps. Even if I weight sort the cases.
2. Do you mean "ejector marks" on the case head? This would be caused by:
A. Overpressure loads in the parent rifle.
B. A sloppy chamber allowing the case to not grab the chamber walls and slam back into the bolt face causing a bit of false pressure signs.
C. Too much headspace in the parent chamber, causing the same issues as "B".
Any/all of these issues would cause the cases to overexpand on the first firing.
