I was reloading 223 this weekend and snap - broke the Dillon. I have had this RL 550 for about 15 years and it has been a workhorse. I called Dillon the first thing Monday morning and they wanted a picture of the broken piece. I sent the picture to them and they called me back and said they will have the part out to fix the 550 within a couple of days. That is a warranty with service.
