IMO, if you want something that big, it seems the 9.3x62 or the 9.3x64 have you covered and have been around a bit longer. I think the 9.3mm are most interesting with the 286gr bullet. Maybe having a non-metric name (for marketing reasons here in the USA... in Europe it's the 9.3x66), it might catch on and be a viable alternative to the 35 Whelen, though.
