Rimmed cartridges rule in a single shot rifle. 357 Maximum for the win!
Fine round. But try finding a rifle, let alone a $500 rifle chambered for it. Once you get one, start looking for ammo and/or brass.
Point of the .350 is easy, cheap, available, legal everywhere, and good enough to get it done. As JB has pointed out time and time again, most don’t load their own. Mostly I do, but I might not for one of those since good hunting ammo and cheap practice ammo is plentiful, courtesy of its .223 heritage (for the first couple or three brass draws anyway.)
