Polishing or Not - Chambers?

[PJgunner]

Rough chambers? Check out a Ruger Blackhawk, either new or old model in .30Carbine. My buddy has a new Model and I hve the Old Model and the chambers are so rough they look like cross sections of the Rocky mountains.
Even the lighter cast lead plinking loads are hard to eject and full power M-1 carbine factory or milsurp ammo requires removing the cylinder and using a proper sized dowel and a hammer.
Several others of that model gun that I've looked at also have those very rough chambers.
