Finn Aagard (spelling?) once calculated the slightly larger case of the 9.3 was worth about 30 fps.
In reality , they are both 36 calibers with only 8 thousenths difference in diameter .
The way I see it , the advantage of the 9.3 is about 10 grains in bullet weight......the Whelen will do with 275 s what the 9.3 will do with it's 286 s . Whelen factory loads are also held to very moderate pressure for whatever reason .
The real difference is the heavy bullets which also could be used in the 35 bore have been neglected for the Whelen cartridge .
