That's what I figured but then I decided it was worth a try Sent from my SM-G935V using Tapatalk

Call or email Dillon and let them know your primer alarm is not working. I picked up a used 550 last year and found the same problem. Emailed Dillon asking if that was covered and they replied for me to send them my address and a replacement would be shipped out. Sent from my SM-G935V using Tapatalk

I had some do the same thing. After a closer inspection I found the ejector was causing a slight notch in the rim and kept it from seating correctly. Before I saw that I ran the pieces through the resizing die quite a few times and still had the issue. Once I saw the marks from the extractor and filed them down they seated just fine. Is it possible you are having the same issue? Check closely Sent from my SM-G935V using Tapatalk

The 1200 has been discontinued. I wasnt happy to find this out when I ordered mine from the Dillon site. Only to get my order without it and it showing on the invoice that it was discontinued. So rather than getting a call telling me it had been discontinued and to see if i would like to go with the 1500 they just deleted it from my order. Which I then had to place another order for the 1500 and pay another shipping charge. That would be the only complaint I have had with Dillon's customer service. I purchased a second 550 used which the primer sensor was broken contacted customer support and they sent me a new sensor no charge.

Try Rocky Mountain reloading, I have heard they are the same as berry's. http://www.shop.rmrbullets.com I have had no issues using them and the price you see includes shipping.
