I am new to the long range shooting along with the addiction to accuracy problem I have. I wanted to know what you guys keep in your log book each time you go to the range. Is there a certain format that you need to keep it in so that when someone who knows what they are really talking about looks at it they won't find it comical. I am a Land Surveyor and am going to use a field book that surveyors use. The book is waterproof and also the sheets are coated with something that is weather resistant on archival paper. Other than the ammo information and rifle used, temp, and wind what to you record. I am not hand loading yet but plan to be up and running in the next month or so.
