If you are thinking a double is possible, a cartridge that is the rimmed ballistic equivalent of te 9.3x62 is the 9.3x74R (rimmed). It is available in many brands of doubles at about half the price of the big boys (470 NE, etc.). It is not over-powered for buff; in fact it is perhaps on the line between marginal and not though it has been used very successfully over the years. It is growing in popularity and Hornady offers loads and brass along with Norma and others.
