A 3 ring note book and clear page protectors for log sheets and also actual targets for future reference makes for a nice reference book. I have a Load Log that is similar but not as extended I have used for over 10 years. Has saved a lot of time and loading component money. Find a new load in a forum story or magazine go check it against your log book you may have already tried it and your rifle hates it. KEEP your failed loads as well as the good ones for future reference. Thanks for your log sheet. Happy Safe Loading.
