"so there must have been a lot of "Kentucky Ottawa windage" involved in making the shot. Translation: Skill." - I'd argue that just as much luck is required for such a small target (considering that no 2 bullets are the same and neither are conditions along their trajectory). OTOH, shooting .50 cal does not necessitate direct hit (at least this is the case early on the way) with bullet's shockwave having potential to rip one's limbs off. BTW, I recall seeing one of these tac-50 for sale at a pawn-shop/gun store in Sates - I bet for self defense (though no concealed carry).
