I use a 1.1-4 illuminated Schmidt & Bender (the Zenith model) on my 9,3x62 and see no reason for anything more for this caliber. Although a 1.5-6 would be fine too. The 9,3x62 isn´t super flat shooting, but a good enough big game cartridge out to 200-250 meters in my opinion. I see no need for more magnification.
