Try shooting some compressed air in a can up the chamber before the brushes.. Cooling the brass will shrink it and maybe give you just enough free play to force it out

Another update:
Mark Pharr at Tumbleweeds Custom Rifles had it out in a couple minutes.
Unfortunately, prior attempts at removal left a large burr inside the chamber. Note the spiral on the outside of the case. It will now need some lathe / polish work, but should be fixed in short order.

He removed the barrel and then had a tool that threaded into the case from the chamber end of the barrel. From inspecting the inside of the case, it only threaded into the case less than 1/4 inch or so. 1/8 of a turn, maybe, and the case released and he just spun it out.
As a computer geek I never took a shop class, but it resembled a tap from a die and tap set.

Based on your pic above, the burr or gouge in the metal is likely where the case head meets the chamber. It should polish right out in the lathe. Worst case scenario you may have a tiny dimple from where the burr was polished or re-reamed.
Personally, I wouldn't worry about it since it's not in the neck, throat, bore or rifling areas.
If Mark's not comfortable with the burr, have him set the barrel back a few .001's then re-thread and chamber.

We will test fire at the smith to ensure it is not excessive or binds the case causing an extraction issue.

.308 out of a Savage Model 12 f/tr.
Offending round was a Starline brass, 2nd time reloaded, 168gn hornady match, in front of 43.7gn of IMR4064. (Of which I have fired literally 1000s, without issue)
Case jammed, failed to eject, and then separated when being tapped out with a rod.

I had one stuck and being that I own a shop building engines I removed bolt, had a rod in the case . Used a product called Minnesota fast freeze .
I sprays the case and it contracted so much it did not need any pressure it went loose on the spot . Easy enough to take in your bag when you shoot . I have had to use it a few times now . reloading and you stick a case works great for that as well .. Silly simple wear gloves though its extremely cold
