OK, so no inertia lock.
Progress anyway!
I actually owned one of those for a while, but I accepted an 'offer' an sold it. Mine worked with anything. 70's gun.
What do the empties look like? Can you see any bulges in the rims like from excessive headspace or expansion into the extractor groove?
It's very weird that the problem would just 'go away', which is why I suspected the bolt wasn't unlocking.

Builder, The company and Les Hovencamp have a fix for this issue. I think they weld up and re-cut the extractor slots, not sure about this though. Anyway, I had a 2 barrel Target grade set at one time. The trap barrel worked fine but the skeet barrel did what you described yours did. Les fixed the skeet barrel problem and everything was ducky. Les is at Diamond Gunsmithing in Ithaca NY

You can hone the hell out of the chamber with your brake hone and not lose much metal, maybe 0.001”-0.002”. After you hone try using the brush wrapped with coarse steel wool and dipped in orange rubbing compound like I suggested. I’ve done this myself with excellent results.

PS did you dip the brake hone in oil before you used it? You never want to spin it dry.

I set up a "Tactical" 870 Express for a friend several years ago. Owning several older 870s and 31s and knowing how they work figured it was a bolt parts on job. Not so, Never saw such rough finish inside a gun. I had to polish almost everything. Add rough finish to cheap shells, not surprised it would not function .
Honing chambers or anything else it's important the lap be a close fit. Split dowel & paper not touching the sides won't have as much effect as close fitting turned wood plug & paper, which should be enough for a pumps chamber . Reason the brake hone worked was its fit. Finish lap usually lead cast to fit. .

The three legged hone was a very close fit. In fact, the specs say it is bigger than the bore of the chamber. It wasn't. Of course I used oil and I think I removed one or two thousandths from each side, no more.
It has been fun and I learned a lot and I do appreciate all the help I received from you all. The collective knowledge here is amazing. The gun is running and sometimes it is best to leave alone things that work so I will now just use it and enjoy it. I suspect it was the chamber roughness and if its ugly head re-emerges I will try the orange rubbing compound routine.
So many guns, so little time!

You can use rubbing compound depending on the surface you are starting with. I like course grit then work through the grits to final finish, not spending a lot of time with any one, each one removing the marks from the last. Valve Grinding compound is a good start for a rough job.

240 like the hone you show grit not all that aggressive and probably a good one for a rough not rusted chamber job. Some good charts on line showing the grit rating different compounds, papers, steel wool, 3 M pads etc, worth a look. Guessing only shiny chamber raw metal not coated with something like Crome, probably finished 400 or 600.
My go to for rough starts is Permetex valve grinding compound. 150 I think it is, don't stay with it any longer than needed then move through the grits smoothing out the lines one before left.
Outside work on my lathe this weekend finished with 2000 grit paper. Shines like a mirror. From 150 start 10 papers to get to 2000 . Main thing any finish work is go through the grits methodically don't skip one stop when it's good enough.
