I just got some 9mm from J&K on Sunday and I was so pumped to load some. While switching my 550 over to 9mm when I hear something hit the deck. Looked down and saw that some part of the powder assembly had broken off. I attempted to attempt to fix it, but it was beyond a simple repair. The guy who answered the phone at Dillon was cool. I bet he reloads. Our conversation lasted about 5 minutes. Shipped the assembly off this morning. I hope it goes well.
