Well guys, I have to say - thank you very much for many helpful ideas! I figured I really didn't have to go to the extremes of high-polishing brass especially if I don't care about how shiny it is. I just wanted to get some reassurance that the "myth" about dirty brass tearing up your dies was just that - more of a myth than a reality.
You all have confirmed some of my thoughts, and I am thankful for your feedback. Now, all I have to do is gather more .38/.357 hulls whenever I find them!!!
Thanks alot guys.
