I've tried it on predator calling stands, since a shotgun and a rifle might seem appropriate, and the distances walked to a stand tend to be short.
I can't imagine trying to stalk this way. The second firearm will invariably get in the way, bump against the other one, and left me wishing that I'd left the 2nd gun in the truck. I carry a handgun always, but long ago settled on one long gun when hunting.
Some things just aren't6 worth the hassle.
