I now keep all my ammunition-creation data on a computer. Sure, I’ll make notes when working up a new load or tweaking an existing one, but ultimately my data is stored digitally. Since my loading room is only steps from my computer, the transition from written to digital data has been easy for me. Now that I’m using the handloading app from RCBS, it’s even easier, and it also makes recreating my favorite loads when I’m at the loading bench more convenient.
