The 9.3 cartridge is a boomer with quite a bit of recoil. A 1.5x-6x type scope would work fine, and the Elite 4200 comes to mind, but the problem is that it has short eye relief for such a powerful cartridge IMHO.
Leupold's generally have the longest eye relief, and I would strongly look at the VX-II or VX-III in a similar magnification range.
Another good choice would be a Zeiss Conquest in 3x-9x-40mm because it has a full 4 inches of constant eye relief. The 3.5x-10x version only has 3.5 inches.
