I am not a long range shooter, but would like to become more proficient at more extended ranges. I don't know what is considered long range or medium range, but I am talking 400-500 yards. Is there a good book available that will teach me the basics? I am a hunter, and enjoy shooting and find myself shooting more than hunting. Never shot beyond 200 yards at the range, and longest kill was a doe at 200 yards. I feel pretty confident at 200, but beyond that is unknown for me. Goal is to become good enough to consistently shoot MOA at 500 yards. Also, along with that is there a good pattern and dimensions for a shooting bench? I shoot at my friends place, he has a shooting shed with just a plywood framed bench...he is talking about making one out of concrete and asked me about size and height since I am the one that uses it most. Any help/useful advice will be appreciated!
