Have not seen him. I do shoot a lot of duplex loads

Colt made a fairly small number of the "Whitneyville-Hartford" revolver. Think of it as a Walker grip frame fitted to a 1st Model Dragoon. Way over simplified, but still useful. Believe it or not, I've actually handled one.

Anyway, these were made to replace Walkers lost in service, primarily due to cylinder ruptures. 60 grains of "sporting rifle" powder created too much pressure. I assume the powder to be roughly equivalent to 2F, but I don't know. The W-H had a shorter cylinder, holing only 40 grains with a round ball, a pattern continuing through all 3 models of Dragoon.
