The 9.3x62 is a 78gr. water capacity case as I measured on 2 fired Sako cases. The Improved .375/06 I shoot with the shoulder moved .030" forward has identical capacity to the 9.3. If you want to compare the two Whelen rounds with the 9.3x62, they must also be on improved cases to make the comparrison fair.
; Note much data has the .338Whelen or .338/06 if you want to call it, running consistantly 100fps ahead of most data for the .35 Whelen. Ever wonder why? The capacities are identical, which means if they are loaded to the same pressure with same weight bullets, the .35 calibre will produce higher velocities, not lower. That's just plain common sense in ballistics.
: With the bullets available today, the .35 is a good 300 yard Moose, Elk and Bear gun, just as the .338/06 is and same with the 9.3x62. I do not believe anyone should be shooting our valuable big game at longer ranges than that and I don't give a crap what calibre you are shooting. Too many things can go wrong just as or fractions of a second before the trigger breaks. Even though the 9.3x62 has greater capacity & therefore the ability to shoot same weight bullets faster, or heavier bullets just as fast, you would be hard pressed to tell the difference between any of them on the same game animal.
