My 9.3x57 cases made from '06 brass, would not allow a .367" bullet into a fired case, thus they needed to be neck turned. I ended up going with RP 8x57 brass as they did not need turning. Even the 9.3x57 PriviPartisan cases were thicker than the 8x57's. I preferred the necked straight, then necked down to a crush fit, 8x57's. I rather like my Hornady dies.
I will admit my .50/95 dies are CH and they seem good dies. The set of dies CH made for my buddy for his .376/06IMP were grossly undersized at the shoulder. I sent 3 empties and they ignored them, sending their Generic set of dies.
