There is a succession of load room development.
It usually starts out with all the dies together on a shelf and a press mounted to a bench.
Eventually the reloading room becomes mostly a store room with a few presses in the center. Mine is 9'x11' and filled to the ceiling on all 4 walls with file folder boxes on shelves with big labels on the front of them.
When a new cartridge is started, it gets a new box and label. The dies, bullets, brass, and loaded ammo go in the box. Some cartridges are rich and may have 5 boxes and some cartridges are poor and may share 5 cartridges to the box.
The documentation is the range reports. That is stored in the computer, in the cloud, and in print outs.
A number of presses become satellite presses for the vehicle, the TV, the computer, and other people's houses the may host a hunting party.
