I have seen the 9.3x74 used on several buffalo and it worked fine...but I would probably not want to wade into the high grass after a wounded bull with one given a choice.....

I do not think the really big bores kill buffalo any better than a 416 Rigby, Remington or 404.... I place a lot of emphasis on shot placement as the main criterior...I have seen two instances wherein a a 500 NE and a 470 NE took 9 and 13 shots respectively to kill a buffalo and I have those kills on film....

I know that shooting them in the boss will not stop them with any caliber and I have shot considerably more than 50 buffalo, so now you have another perspective....I have shot Buffalo with a 458 Lott, 505 Gibbs, 450-400, 8x57, 7x57, 308, 470, 9.3x64, 9.3x62, 416 Rigby, 416 Rem, 375 and 30-06. maybe a few others....

The older I get and the more big game I shoot then the more I am convienced that shot placement and bullet integrity are the two most important condiments to killing any animal, caliber rate about 3rd...

I do feel that the fear factor is sometimes a driving force to make folks shoot the larger bores and this is not good reasoning, one should shoot whatever rifle he can shoot comfortably in "ANY position" and he must be truly honest with himself, albiet that is seldom the case with real big bore shooters, once that fear becomes realistic and they realize that the possibles are not likely of an injury, they overcome that fear and most cut back to something that they can shoot, This is not an applicable analogy to all people and some just love to shoot big bores, and a few can even do it....

Now the above is only my opinnion and is in stark conflict with many on these internet board posters and thats OK, varied opinnions never hurt a good discussion....
