In the 1908 Sear's catalog, quite possibly other years as well, they listed a "Little Ladies" single shot shotgun. This was available chambered for either the .44XL or for a .40-85 Win case. This case was in all likelihood the same as the .40-85 Ballard. This was, of course, a rimmed case having a head diameter of 0.480" & a length of about 2 15/16". (Almost a 3" .410) Sears only supplied these as primed empties & had to be loaded. A load was given which consisted of an appropriate charge of black powder with ˝ oz of shot.
