I'm certainly far from being an expert, but I use a MEC 600 jr. It loads and crimps any hull, but AA are my favorite. Looks like from your photo that those presses just need a good cleaning and de-rusting. Of course they need the plastic bottles that hold the powder and shot. Unless you get the aftermarket part to adjust shot amount and powder drop, you'll need different bushings to drop the correct amounts. Shotgun shells are easier to load than rifle or pistol and shotgun shells don't create all the pressures that metal cartridges do.
