I own a Mec650 it doesen't have a resizer. I have and use a ( seperate operation) mac resizer. This way I can check all of my empty cases as I resize them. Don't think it saves any time while reloading, but I know that they good to go. I also have a bt 99 and a over under. I still check & resize before reloading.
