With the advent of rifled slug barrels and sabots, most modern shotguns probably have as much range, and accuracy, as any straight walled handgun cartridge in a carbine. Exception may be some of the new super mags like .460 and .500. Many states now allowing straight walled handgun calibers also limit the length of the cartridge which eliminates calibers like 45/70, etc. Thus, I see no real advantage of handgun caliber cartridges in most cases, over a modern shotgun. While rifles are legal where I hunt, for the most part, if I am not using my revolvers for deer, I'm using a PCC. Same goes for my sons and my granddkids. For one thing, we do not need something that shoots past 100 yards or so and second, being in rural farmland that is being constantly invaded with folks wanting their 10-20 acres of heaven mixed in, it's almost impossible to find a spot in the flat open farmland where it's safe for a bullet to go the distance that a legitimate centerfire rifle bullet will travel. Corn don't stop bullets like trees do. The ground, especially when it's frozen will ricochet bullets to extreme distances. Not so much for the slow moving large diameter generally flat nosed handgun bullets. One still needs to know their target and what's beyond with a handgun caliber carbine, but the chances of it's bullets fired, getting off your property, even when that property is small, is almost moot.
