If you want to bump your production rate up to 150 rounds an hour the Lee Classic Turret press will allow that (the turret auto-advances, which is the essential element to the efficiency). Kempf's gun shop sells a kit that DOES NOT force you to take an extra scale, manual and other stuff you obviously already have. But Kempf's kit does include powder measure, dies, press, priming device and absolutely everything you need to get started on the .380 and nothing (except some plastic ammo boxes) that you don't need. Do get the Pro Auto-Disk upgrade.
If you do add the Lee Turret press, you may decide to get some extra turret disks (they are reasonably inexpensive) for your rifle calibers. The turrets make swapping between chamberings dead simple, and your dies, being permanently installed, are permanently adjusted. (Load 100 rounds of .380, twist the turret out, dump the powder back into the original container and store it. Put away the pistol dies/turrret. Pick up your rifle dies/turret, twist into place, grab your rifle powder, pour into the powder measure mounted on THAT turret. 30 seconds or so. Cycle a few powder charges to check the throw weight and then load 20 or 40 rounds of 30-30. Pull the turret, return powder, stow that turret and pull your 30.06 turret. Put THAT powder in the powder measure (about 30 seconds swap time again). Cycle the powder measure to settle and to check the throw weight and load 20 rounds.
Dead simple.
