I have a log book from Impact Data Books. I bought from Joe Fox from the South Fork Shooting Range. He had it set up to help keep track when shooting groundhog matches. It is filled with all kinds of helpful info. The paper is water proof and heavy its really a nice book but doesn't quite fit my needs. It seems to be more towards sniper stuff with some groundhog added. Lots of info. from drop charts to how to read the wind to the Nato Phonetic Alphabet. Helps you layout a sniper range card to keeping a round count. It has a load developement section and a place to keep your cleaning regimun. Pm me if you have any questions and I can send some pics to your email. I paid $30 for it I will ship it to you for $25.
