Quickie question(s) on polishing brass:
1.) Is there any "preprocessing" I should do to the brass before putting it in the tumbler or is it normal to just dump it straight in off the range?
2.) Does the tumbling take care of cleaning out the crud inside the case, or does that not even matter?
3.) How much exposure to wetness is ok for brass? I spent a fairly wet/muddy day at the range last weekend and collected some spent brass. It sat around for a week or so in the boxes I dumped it in. Does wetness or general moisture degrade the cases at all?
