I cannot think of any advantage in rebarreling or reboring a 9.3x62 to a 375 caliber, not one!...you gain absolutly nothing in killing power or trajectory. No advantage in components? You certainly have devalued the gun to wildcat status and resale will be much less, so why waste your money like that...If I was going to do that then I would open up the action and build a 375 H&H and even then I wouldn't gain a hell of a lot....
