Have you read any of the FAQ and Help sticky as recommended to everyone? The link on chamber polishing is broken now due to the recent software change, and the search is disabled for now, but you need to polish the chamber, it's SOP for new handis with ejectors, the newer extractor barrels don't have the problem, if yours is an extractor, you have problems bigger than the chamber being rough!
There are a couple different methods to polish the chamber, I use a chamber size bore mop on the tip section of a 3-piece rod chucked in a drill, use any fine metal polish like flitz, maas, semichrome or JB bore compound on the mop and polish the chamber for a couple minutes.
You can also use an empty fired case with a screw stud in the flash hole chucked in a drill to do the polishing.

EDIT: After reading your previous posts and you're not reporting anything about FTEs, there may be another issue such as the ejector hanging up or your cases are too long which I suspect is the culprit, are you trimming your brass to spec? http://www.graybeardoutdoors.com/smf/index.php/topic,90071.msg547954.html#msg547954
