It probably is regulated with the scope. Most modern doubles of any chambering smaller than one of the big African cartridges are scoped. 9.3x74R's usually are, since they're typically used in Europe for driven boar shooting, plus red stag hunting. The original scope might not have been a 4x Leupold, but if a Euro-scope was originally mounted it was probably on the smaller side anyway, due to the usual intended use of such a rifle.
You're probably going to handload for it anyway, so regulation probably wouldn't be a big deal. Though with double rifles you never know!
Roger that! Thanks.
