I need to start doing better record keeping, I chronograph various loads, different powders, different bullets, for several different calibres etc... I have the shooting chrony printer, and usually write the recipe on the print out, and keep it between the pages of the reloading manual for that caliber like a bookmark, but am getting too many to be practical, so need to start a record book or excel program or something already organized, looking for suggestions. Simpler the better as I'm lazy and not that into meticulous data entry.
