I reload 380. It's just 9mm with a little shorter case. No problems yet using hp38/w231 powder with a 95gr FMJ for practice loads. I could see 32acp or especially 25acp cases being a challenge.
For those with a Dillon 550 press, to load 380 you can use the shellplate and buttons from a 223 conversion kit and the powder funnel from a 9mm kit. One good part about a progressive is you only have to load the case once into the shellplate before it is ejected as a completed round. Using a single stage press would require multiple handling of the case and that might prove frustrating for some. With the price and availability of 380 ammo, I'd get over any frustration fairly quickly.
