I put all load data on spread sheets that are kept in a 3-ring notebook, and a master reloading data sheet on the wall above my reloading bench. I buy poster board in 10 packs at Office max and use 3" shoot-N-see targets. I put 5 targets across long ways on top and bottom so there are 10 targets per sheet, I write powder at each end and charge above each target. This way I can keep all targets for future reference so I can see how different combinations of powder, bullets, and charges. I also chrono all loads which are kept on spread sheets in the 3-ring binder. Yes this is time consuming but I don't have to try to guess which combos I have or have not tried.
I enjoy seeing what you other guys are using to keep track of your loads.
