Auto-indexing/case ejection - The Dillon advances the shell plate a full step on the downstroke, which allows more rotation for ejecting the loaded cartridge, but it also results in a more abrupt start/rotate/stop shell plate action. The Hornady system is smoother, advancing a half step on the way up, and another half step on the way down, but this leaves only a half step (1/10th rotation) to eject the finished cartridge. This is why the Hornady has problems with FCD and other dies that are installed in the last station, and that must contact the shell plate. Some users have bent the ejector wire to make it work, others have ground off a portion of the bottom of the die to clear the ejector wire, and still others have removed the ejector completely, electing to manually remove the finished cartridge from the shell plate. When you consider the extra time used to transfer loaded rounds from the catcher bin into ammo boxes, manually moving the finished round from the shell plate directly to the box does not impact throughput as much as one might otherwise expect.
