Lots of info, all of it needed to get to that ELR target. Here is a pic of some of my BAL charts made by him for my custom 6.5 x.284. These things are perfect out to 1400 which is as far as I've tried them. He did every range out to 2000 long hand in ten yard increments. When he gets to the section when he shows how to make them he said he's simplified the system. Just hope I can comprehend it.
I used these charts to harvest my whitetail at 908 that is in the trophy photos section of LRH.
