When Carlos shot the NVA sniper I doubt it was from particularly long range, despite his 700 yard zero. Those guys had been stalking each other for quite some time before Carlos got his shot at the sun glinting from the objective of what is a very small and very short 3X Chicom scope. These things are probably little more than 6" long and the objective diameter is little more than 1" in diameter. Whether it is as likely to stop a heavy bullet from a .30/06 as effectively as a modern scope is a point of conjecture. Carlos never claimed the shot was anything more than a fluke, and unlike Myth Busters, who as often as not come up with an incorrect conclusion from a test plagued with unrealistic parameters; whether they are blasting concrete from inside a mixer truck, shooting a bullet into the cylinder of a revolver, or shooting through a scope, I won't bring Hathcock's honesty into question over a one a million chance shot, made during a dangerous confrontation, under combat conditions, in which he prevailed. It doesn't have to work every time, it just had to work the time he did it.
IIRC The shot was far enough that Carlos saw a glint and not a shooter...No idea what that meant or means, but it wasn't real close is the gist I got.
Might be time to dig out his book again, but that is what I remember?
There is no doubt in my mind that what Carlos said actually happened.
I never met the man (God rest his soul) but having read his book and watched his interviews his matter of fact honesty seemed crystal clear to me.
Strange how the battle hardened snipers are generally so straight up, modest, and understated.....Take Rob Furlong for instance.
