I see the 9.3x74 factory ammo as running 2,300+ change with a 286gr. bullet, while the .375H&H runs 2,500fps and change with a 300gr. Loaded with the same weight as the 9.3, ie: 285gr. bullets, the .375 will usually run well over 2,600fps quite easily, maybe more, afterall, my 9.3x62 does 2,519fps with a 286gr. Norma.
