Step 1 - De-prime all cases in one step and then set them on the bench straight up, base down
Step 2 - Take an inverted sleeve of primers - place on work bench - slid the paper cover back that will put the primers on the bench upside down
Step 3 - Separate the primers with your finger to give them some space from each other
Step 4 - Pick the empty hull and press down on one of the primers - it will partially go in the primer pocket
Then, fully seat the primer and then do your normal reloading steps
I don't use the Lee Primer Feeder because it's a PIA if the primers start to jam up in the feed channel of the tray ... in addition the all plastic feeder is expensive
