Up until a few months ago, I kept reloading notes either in my reloading manuel or on scraps of paper. I then started keeping extensive notes in a college composition book. A few days ago, I found the "Hand Loaders Log" by MTM/case-gard. A three ring binder, it has different charts to keep accurate notes for each of the loads. The Log also includes different types of targets to help keep notes. Not sure if anyone cares, but I find it to be an excellent organizational tool
