Thanks for laying this out for us. I have been dealing with the same issue with a new Anti-X action and a burr on the ejector hole. I though it would wear out but looks like I was wrong. Time to send it out to a gunsmith.

Understood, I sort of figured that was the case ...You know, I used to think I could just spend enough money on an action... and I wouldn't have to worry about it.
Fact is, I was wrong. Every action manufacturer I'm aware of, has turned out a bad action, more than one... and some have taken to it as a matter of course. In the last year, I've seen issues with literally every single company that produces an all-integral action. So the answer isn't with the action manufacturers... but a smith that will actually take the time to evaluate and fix them.
The action manufacturers either can't, or won't. Doesn't much matter which it is. That's why I'm using Stratton Custom Rifles. Every action... it all gets checked, and anything that's wrong... gets fixed, or the rifle doesn't leave the shop. They actually get test fired. A lot of shops, don't even fire what they build. Not even once. People don't realize how important that is, until they experience a problem like this.
Then when the customer finds the problem... it's a never-ending game of "well ship it back and we'll take a look."
So to sum up, an action is either all the way right, or it's not. There's no way you can know, without checking it all. A rifle isn't complete, until it has a trigger installed and perfectly timed, with confirmed pinfall and no drag. A barrel needs to be installed with a chamber confirmed true to the bolt face. This is just a fly by of what's needed... but the smith either knows it and DOES IT EVERY TIME... or he doesn't.
Didn't take a pic ahead of time. Fact is, there wasn't much to see without extreme magnification. By the time I discovered it, the burr had already accumulated a pile of brass anyway, so a pic would be a moot point. The burr was on the ejector pin hole, not the ejector pin. The pin is unmodified.

That could be false pressure. How does your load compare to what others are shooting?

2650 with a 180 ELDM. 20" 7ss. I don't think I should be to pressure with 62 grains of N565. @lancetkenyon is more familiar with N565 & the 7ss than I am
That doesn't look like real pressure to me. Primer is not cratered, not flat, and there's no actual wipe... just ring.
You can easily answer the question with finality, if you keep bumping the charge weight down. If it still persists way away from where any pressure can possibly be... then you will know for certain. If it only shows up at the top end, then you can be sure it's pressure.

Doesn't look like pressure to me. That primer looks really good.

Yeah I'm def going to try that. The next shot had a much more pronounced ejector markThat doesn't look like real pressure to me. Primer is not cratered, not flat, and there's no actual wipe... just ring.

According to the load data I found your charge weight is pretty much bang on but your velocity is like super slow, even for the short barrel. how many rounds you have through that unit?

I've got 75 through so far

It sure doesn't look like anything I would be concerned about. Primer looks awesome. Very slight ejector mark/swipe. How was bolt fift?
In my experience usually 150-200 rounds before a barrel picks up all its speed so you might see a velocity increase soon. I'd get a few more rounds through it and then re-do load development.
I do think you likely have a burr on your plunger hole

Bolt lift was fine. I don't see any signs of pressure apart from the ejector mark. It's got me a little confused. The second picture I added shows a little brighter ejector mark
