If you are reloading 9mm, .223, or .308 with a Dillon XL650 chances are you have or are dealing with powder throwing. As the shell plate indexes to the next station, it snaps into position via a spring loaded bearing underneath it. If your cases are loaded too close to the top, it will throw power once the shell plate finishes its index. I was able to solve this issue with a $5 replacement bearing and by cutting one coil from the spring.
