Have you checked your chambers lately???

[Pal Val]

Those pictures look to me like gunk left over from shooting .38's in a .357 mag. I would give those chambers a thorough cleaning before passing judgment. I've seen that in my guns plenty of times.

I'm not a fan of glass-smooth chambers. The brass needs something to hold on to right after ignition. If the brass is slipping and sliding at that critical moment, accuracy can be affected.

Good stuff from Knuckles.

Val, I see the logic in your statement but you should see the chambers in my S&W 29-2's. They look like mirrors and still the brass hangs in there.
