I have a 9.3x62, an Interarms Mark X fitted with a Lothar Walther barrel that was trimmed to 20" and bedded in an Interarms Mark X mannlicher-style stock. It is half of a matched pair, the other being chambered in 7x57, that I put together for a second trip to southern Africa. It shoots good groups and isn't unpleasant to shoot with 286 grain bullets. I don't know that it is a cartridge that is necessary or even particularly useful for shooting game in the contiguous 48 States, but I like it.
I have zero experience with the 35 Whelen, having opted to go with the 338-06 in one of another match pair of rifles.
