Regulations in Zim have a minimum energy requirement, which neither the 9.3 X 62 or 9.3 X 74 meet with factory loads. That said, when did the Mugabe regime ever care about the law?
Talk to your PH. Most all that have seen it in action are happy with it. There are places I've hunted buff with the 9.3 X 62 that state the .375 H & H is the minimum, but the PH's accept the 9.3 X 62 as the metric equivalent. I'm not sure very many of the game scouts can do the the math on the conversion, and thus really object.
