Frankford Arsenal Platinum Hand Depriming Tool Depriming 50 x 308Win at the rate of 12 cases per minute. Slightly better setup will increase that to 15 cases per minute reliably excluding emptying the used primer holder. The unit is reliable and fast to do a few hundred without too much effort.
The advantage of de-priming first is that cases going into the Frankford Rotary Tumbler with stainless pin media will have their primer pockets cleaned at the same time, reducing the time of case cleaning.
