A late input but anyway.

I am sure your 9.3x62 will be fine for whatever you use and here in Sweden it has almost become a second national caliber after our 6,5x55, at least when you want something big. Ammo supply is outstanding in this caliber.

However the latest years the 375 has become really popoular even if there sometimes can be hard to find ammo at some dealers.

Why then. We got a big rise for Wild boars here and younger guys (even if not dreaming of Africa) wants to have something bigger than the regular 6,5x55, 308 or 30-06 and often chose the 375 thanks to the wide range of bullets.
