Chuck's record was attempted, in daylight, with NO incoming fire, by a Modern Marine Sniper, and was NOT duplicated. The M1A was his choice on the river bank that night, with what is today considered a primitive Starlight Scope.
Him and Hathcock, against the Cobra, are stuff of legendary snipers. The top 10 and their rifles. Oh and a little history on those "cheap" Moisins that occupy the top 5.

Thanks Peg.
