Anyone knows the guy? Any thoughts?
Not sure , but Dick must of been a good shot
…and dead too?
Alex, dead shot in this context has the meaning of hitting “todsicher” (dead sure).
For example, the company of American Powder Mills produced a propellant called “Dead Shot Smokeless Powder” (Arms and The Man, 1910).
Like AmmoOne, I assume Dead Shot Dick refers to a person which was, if nowhere else, good at shotgunning.
