Yeah, I'd vote for the 9.3x62 rather than the .375, both due to just about eliminating any stock-splitting issues, and more reasonable recoil, especially with the pad Ruger puts on the African model.
I bought one of the first African .275's that showed up around here, and shot it maybe 50 times before somebody offered me too much money to refuse. The stock hadn't split at that point, but based on the experience of others it probably did later. The recoil of a .375 (whether H&H or Ruger) often seems to be dividing line between a wood stock splitting and holding together. Have owned a number of 9.3x62's and .35 Whelens with non-reinforced walnut stocks that didn't split.
