Take my word as a Marine Corps Shooter, this guy has the right stuff.Not only the basics of mid and long range shooting are covered but the common mistake that we all do without thinking. Guys get this Book put it in your shooting stuff, keep it with you at the range, I promise you that you will use it and be a better shooter, and listen., real good now, DO NOT LOAN IT TO ANY ONE. Once you have it , you have all calibers and loads of ammo that is essential for the best accuracy,so every different load you fire , you can add or take off your dope with no problem,one more thing we have to get organized and this will be a tool to help us.Keep your mind on shooting, nothing else, you have to make that shoot, and you can if you clear you mind of all the non sense in the world, see that shot in your mind, before you squeeze trigger. Keep your powder dry.....B
