It is .410 shotshell. Federal figured it could sell more to the "Judge Crowd" by calling it .410 handgun ammunition.
It aint nuttin special!
Federal Premium:
.410 Handgun Ammunition
With the success of the Taurus Judge revolver, Federal added .410 shotshells designed and optimized for use in .45 Colt/.410 handguns to their Personal Defense line of ammunition. The use of an extended shot cup improves the patterns produced by these rounds
Although the boxes are labeled “Handgun,” this ammunition has the same structure and dimensions as other industry standard 2 ½” & 3” .410 shotshells. This means they are safe to fire in dedicated .410 shotguns, including those models fitted with full chokes, as well as .45 Colt/.410 handguns.
