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.
Everywhere I took a 9,3X74R the game scouts thought it was a 375.
