The problem with that is I get the brass home from the range, and I immediately tumble it. I don't necessarily do it for trade brass, I do it because I may use it and I like it to be shiny and ready for reloading. I can also see any defects much easier on the brass if it is cleaned and shined, so any brass I do send won't be defective and you don't feel ripped off. I mean I have had brass that the tops of the primers pop off when I decap it , but the sides are still wedged in the flashhole. Splits are easier to see if it's shiny. It helps me to make sure I am sending you good brass.
