I don't need my chamber walls and cartridge cases to win beauty contests. Making 'em shiny and bright does nothing to the bullets' performance down range. Besides, nobody ever sees them when they're used to do their thing shooting a bullet out of the barrel.
While I understand and respect your opinion, I am a highly OCD person, so to me bright and shiny clean brass represents cleanliness, just like a nice polished chamber. To put dirty or stained brass in a nice polished chamber is kinda like getting a shower, and putting on dirty clothes... And putting slightly dirty brass in a dirty chamber will eventually cause a gum-up issue and difficult extraction. That's how I would imagine it. Not saying I'm right, just saying that's how I feel about it.
I still think the OP's problem is from a generous factory chamber, with a slightly too large or out of balance reamer at the factory.
I am about positive that my issue is that the factory chamber is either A) slightly oversized, or B) was bored too deep allowing slightly excess headspace, causing my case/head separation issue.
