I used my 458WM decapping die to deprime everything until I got a Lee universal die. The advantage of decapping before you was cases not only cleans primer pockets but allows for faster drying of cases. I personally do clean primer pockets and also use an inside outside deburring tool on all my cases as well, and never put dirty cases in my dies now I know better. I purchased some citric acid powder from a home brewing company and use that as my wet cleaning agent with a drop or two of dish liquid in tumbler. I sold my dry media cleaner as I believe wet cleaning to be safer from any air born toxins. Regards Stephen
