I picked up a bunch of brass at a local range, mixed cal., 3 different times. I loaded some 9m and 380s for the kids for christmas, to see how they liked them. I'm on my thrid loading session of the 380s, loading about 100 at a time. For some reason the neck splits on about every other one, on this session. The good cases are taking the bullit about 1/32 to 1/16th. That shows me that I'm not over expanding the necks. I haven't changed settings since I loaded the first. Lee 380 ACP, 90625 I guess I need to take it apart, clean and lube.
