I loaded one with CCI #350, WLP, and WLR. They all looked the same once seated and gauged 0.018 below the case head. I guess I was just used to what my 45 Colt loads with a WLP seated looks like. The 500L seats slightly deeper.
I ran into trouble with CCI primers years ago with my 454 Casull. After contacting CCI, and sending back some miss-fired cases. They said I wasn't seating them deep enough. I guess CCI uses the bottom of the primer pocket to cause the primer to egnite. After that was brought to my attention, I switched to Winchester, or Remington primers. And never had that problem again.
