Here's what I found out... a "shotgun/rifle" combo referred to by the Indiana DNR rules is NOT the same as the Circuit Judge format. The Indiana DNR is talking about over/under shotguns that shoot .410 out of one barrel and .45LC out of the other (or any combination of shells and calibers). The Circuit Judge is not considered a "shotgun/rifle" combo... rather it is considered a "revolver/rifle" combo and is ok for deer hunting.
