I am new to wet tumbling, I have been tumbling pistol cases with the primers in and 223 cases with the primers removed, I use a Lyman case dryer to dry cases. I use Armorall wash and wax and Lemishine to wash the brass. After reading horror tales online of rifle barrels being ruined by pins shot through them I have become very worried about pins left inside of cases after wet tumbling. I am using a Frankford Arsenal Wet/Dry media separator filled with water to separate the pins from the brass. So far I have not found a single pin in the brass after using the media separator. Do others find they get this kind of results with a media separator or am I just lucky so far?
