I created a spreadsheet that has one page of ammo reloading components and another page of loaded ammo with the reloading components added in.
I created it in Linux LibreOffice Calc, so the formatting of that file is the same as I use. I also saved it into Microsoft Excel, but I’m sure much is lost in the translation.
Feel free to make use of it. The data is not mine (does not resemble or reflect my inventory). You will have to modify to suit yourself. I doubt it will have much value to anyone who doesn’t have some skill with worksheet manipulation.
The Linux user version:

The Micromush one:
