Stepped Reloading Tray

My dad has these reloading trays that he really likes that are stepped, but they're too deep for reloading 9mm. He also has these flat trays that are perfect for 9mm, but he really wishes they were stepped. So what is a dutiful child that wants him to keep reloading them some 9mm to do? Break out the calipers and mish mash the two together.

Then share it to the internet.
