Has any body ever tried polishing the inside neck of there brass? I am considering using some brass polish compound and spin something on the inside of the brass to create a smooth polished surface. Does any body know how this might effect the accuracy and other performance of a load? I tumble all my brass and add polishing compound but the inside doesn't seem to look all that shiny and smooth. It would seem to me that having a polished and smooth surface for the bullet to exit from would help the bullet to exit more smother and be more accurate.
