I would prefer the 35 Whelen myself, but just a suggestion you may check around for availability of ammo for a 9.3x62, it may be easier to find than ammo for a Whelen I would think ammo for either would be hard to find. Ballistics are very similar between the 2. A few years back you could buy a cz 550 chambered in 9.3x62, may still be able to. and Tikka lists one in their catalog but I don't know if any actually make it to the states. Anything shot with either I'm sure wouldn't know the difference.
With the Whelen you'll have better availability of components and bullet selection if you decide to reload with ammo at 60$ a box it wouldn't take long to pay for a good single stage press, scale, powder measure and the other necessities.
Good luck on your search.
