Great suggestions above!
I keep my reloading & shooting notes on 4"x6" recipe cards (in pencil) filed by firearm in a recipe box.
By keeping individual rifle and shotgun records on separate cards, I have a complete history of the loads (brass, powder, primers, seating depths) used, including the ones that work and also the abandoned loads. I don't have to wonder if I ever tried a certain powder or bullet combo, and I know what works and what hasn't. I even keep a record of .17 HMR & .22 rimfire fatory bullets tested in each rifle.
And I also keep a running inventory of my primers & powders.
Simple, but effective for me.
