Your 9.3 x 62 should serve you just fine. I'm going on a Plains Game hunt this August with Cruiser Safaris. My 10 day package includes Kudu, Blue Wildebeest, Gemsbok, Impala, Blesbok, and a Warthog. We did a lot of research prior to booking with Cruiser Safaris. Their package was similar to what other outfitters were offering. But their price was a lot less. After booking with them I discovered a half dozen local guys that hunted with them and loved it. Several have booked multiple times. I am taking a 35 Whelen, which is a kissing cousin of the 9.3 x 62 and a 6.5 x 55 Swedish Mauser. From all the articles and posts I've seen on this site, I'm not expecting any issues or regrets.
