Hello everyone! I stumbled on this by accident, and am extremely pleased to find such a large group of long range shooting enthusiasts! I find myself quite surprised after studying some of this, that most long range shooters use external calculations, which honestly I was not completely aware of. I must be a serious instinct shooter ( I have been shooting since age 7, 47 now) I have made long shots with only visual and mental calculations, and of course knowing my equipment. Am I a good guesstimator, a freak, or just lucky?
