I know there are countries that allow the 9.3mm calibers as an exception to the regs that .375 or larger is the minimum for the big five, has anyone ever taken buffalo or elephant with one of these? There are much more affordable doubles in 9.3x74mm than almost any other chambering(that's suitable for the biggest game), Zoli makes a nice o/u which I like. Caesar Guerini, who makes my favorite o/u shotguns, makes a double rifle now in 9.3x74mm though I have yet to handle one.
