I can't imagine a single reason that would lead me to select the 9.3X62 over the .338 Win. Mag.

The truth is, there are quite a few medium bore cartridges in this power class that'll overlap in terms of performance, and accomplish pertty much the same things, so why not distill the selection process in the most practical manner possible and go with the cartridge that offers the widest availability, and the least amount of complication?
