I have been to 3, week long formal training schools, all taught by military sniper instructors. I've learned something at each school. While no training seminar will teach you how to be an accomplished long range shooter, it is possible, as others have stated, to at least gain the knowledge of certain aspects of the sport which can be taken home and built upon. After the seminar, and once a person gets home, is where the "work" or "fun" starts. If one is dedicated and practices the techniques that are learned, does research and continues to learn they can become proficient, but it will take alot of practice after the training.
Plainsman isn't claiming that he can make anyone an accomplished long range shooter in 2 days, or even a week. However, he is an accomplished shooter and has alot of information, learned over many years of shooting, and will provide the base of knowledge that a shooter new to long range shooting can build upon to become an accomplished long range shooter, IF that person has the dedication to continue learning and put in the many, many hours of practice that are required.
Hell, he can even outshoot me...........sometimes.
