I would like to add that technique can make a significant difference in the time it takes to deprime using a single stage press and a universal decapping die. Having been a punch-press operator in my misspent youth, I leaned to employ techniques to make the process faster. For instance, after depriming the first case, leave it in the shell holder as you pick up another case to be deprimed. Holding the spent case in the palm of your hand with your little finger, use the thumb and index finger to take the deprimed case from the shell holder and slip the case with the spent primer into the shell holder in its place. That, opposed to removing the deprimed case, putting it into a bin and then picking up another case to be deprimed...which takes longer.
