spp staying in case
Quote from Reloader on April 19, 2011, 1:45 amI have been reloading 9mm fine, but have run into a problem reloading 40 s&w. After reloading 300 40 s&w, I noticed about 15 of my reloads had the old primer still in them. I then loaded 100 more, and found 8 used primers in the new ammo again. Is my deprimer pin not getting the primers removed all the way, and then I am pressing the old primer in with the new primer?

Then it gets pulled partway back up into the primer pocket, and the new primer reseats the old primer again.
Take medium grit sandpaper and round the tip of the pin, so that it can't dig into the anvil of the old primer and get stuck.
