It was at Springfield MO. where Hickok dropped Dave Tut. The claim it was at 75 yards but if indeed it was at 75 yards, it was more likely luck than skill because at 75 yards it is difficult with today's revolvers & semi autos & their advanced sights, although not impossible with a skilled pistolero. I have shot at silhouette targets at 100 yards with a .357 & you certainly had to allow for trajectory & windage & still is quite difficult plus you had to take your time. It is possible that Hickok did take some time as he may have figured that Tut couldn't hit him at that range so he may have made some allowances but who knows exactly what happened.
The underpowered .36 cal. round still mystifies me as to how it caused the mortal wound but anything is possible.
The conflict was over a pocket watch that belonged to Hickok but was won by Tut in a poker game. Strange, both were friends at one time.
One thing Hickok had, was cool under fire. His preference for the Colt navies still defies logic because the .44 was the magnum of it's day & was the reason the army wanted a man stopper & the 60 army was the choice. But...in Springfield MO. Hickok did indeed defy logic with that shot. Truth is stranger than fiction.
