My customer number at Dillon is 19XX....that's how long I have been with them. Original 450 upgraded to 550 upgraded to 550b. I load for machine guns so I have loaded literally hundreds of thousands of rounds, if not more.
My 550b has been kept running for many many years now and it never cost a dime to repair.
A spare parts kits and small parts here and there keep this machine humming.
I would not base my dislike of Dillon on one incident. They stopped the lifetime warranty on electronic stuff some time ago.
Completely understandable in my book.
