A new toy to speed up ammo loading. It’s set up for .40 S&W…didn’t figure out until I’d done about 10 rounds that I had the wrong primer feeder on the press. Small primers don’t feed worth a crap through the large-primer feeder. Once I had that sorted, I loaded the rest of a box pretty quickly. Four pulls of the handle produce one finished round. With a single-stage press, you do each step on the whole batch, which is a lot of moving brass in and out of the press.
