Tim, I'd say it was more a product of timing than any other single factor. The .44S&W Russin was a very accurate cartridge in the New Model #3 revolvers that came on the shooting scene at he time (1880-90s) when target shooting became a popular sport and Revolver Clubs were springing up all over. Top shooters of the day were all members of the top clubs ( Springfield Revolver Club, for example, which had evolved from the S&W Factory shooting team ) and set records that survived for over 100 years. American Models and Schofields fired cartridges that were inferior in accuracy to the .44S&W Russian round in most cases, however a top shooter could post great scores with those guns as well as the NM#s.
