Interesting comments.

I think a .44 Special revolver would be competitive in the center fire slow fire match, possibly even picking up a point or two with 'scratch' hits that brushed the higher scoring ring by virtue of the wide bullet. The problem would come with timed and rapid fire, where along with aiming, one would have to deal with either rapid hammer manipulation or shoot double action. (I realize bullseye shooters already knew this, but thought I would explain for the benefit of younger correspondents who might think 2700 is the model of the latest smartphone)

I shot 2700 competition from 72-73 on the army's time, from divisional to all army level. I never saw a single revolver. As best I recall, the Marksmanship Training Unit at Ft Benning, who had the resources to get pretty much what they wanted, had determined through experience that shooters did better with self-loading pistols. The mission was winning, not nostalgia, so sixshooters were history.
