9mm is a PITA to reload. You have to sort for .380 and 9mm Mak cases that look very similar, look into each case and remove the ones that have the setback ledge in them, and as mentioned check for crimps and now for norma small primer holes. No matter how well you sort every now and then on a progressive you feel a crunch and have to stop and figure out what went wrong (while avoiding a double charge).

Most people at my range don't bother to keep them and there are enough stray cartridges around so you have to resort every time you come back from the range. All this for reloading the one round where you only save pennies vs factory rounds.
