I recently saw you test to disprove Carlos Hathcocks memorable shot. You claim a myth, however you did not use a scope of the period, fixed non-zoom telescope. You should avoid trying to discredit one individual with the honor he represents! If you had not mentioned him by name, I would say you were correct. However, since you did not compare an equal circumstances, I rather doubt the two subjects were at equal altitude. Facts that you failed to mention. Also glass quality has improved much in 50 years,, guaranteed! You also failed to say what caliber you were shooting, 308, 30-06, or 50BMG. All weapons he shot during his time in Vietnam!
