eastbank,
The reason that I am planning to have a long-action 760 re-bored to 9.3x62 is that the 9.3 is ACCEPTABLE for "dangerous game" by African game departments & the .35 Whelen is NOT.
I also am considering having a 760 re-bored in .375 Whelen Improved or .400 Brown-Whelen Improved .
(IF you've never shot one, the .400 BWI does NOT really "kick"; instead, it just PUSHES the shooter. - In a 8# rifle, I find the .400 to be MORE comfortable to shoot on the range than a equal weight pump .30-06 is.)
Btw, 400 grains of bullet at >2,200FPS equal to the power of the well-regarded .404 Jeffery, with the 380 grain .375 OR the 287 grain 9.3x62 not far behind in "practical killing power".
In the hands of "a cool shot", I regard all 3 calibers as "suitable for any game, Worldwide" AND none of the 3 calibers as "too much gun" for WT when loaded with a 180-220 grain GCCB at 2000FPS.
A slightly "off topic comment": My "little brother of the heart" created me a .30-06 SMALL GAME LOAD that is PURE DEATH on squirrels/rabbits/etc. & does NOT ruin much edible meat. - The load is a PBCB at about 800FPS & deadly out to 60+M.
(GREAT practice for big game season, too when the "target" is a running swamp-bunny/jackrabbit).
yours, satx
