One can discuss that.

I mostly used the 500gr SP bullet from Hornady for the cartridge 460 WBY-Magnum. The bullet worked very good, enough deep penetration and wide wound channels.

Even with the 10.75x68 cartridge and the very simple original 22,5g thinly coated FMJ bullet from RWS, I had a good working with buffalos dead in place in the two cases. This cartridge is a different topic when it comes to its use for hunting DG.

I think that the smaller the caliber, for sure the more you have to pay attention to the bullet. With the cartridge 9,3x74R I only used 19g FMJ bullets. There was hardly anything better for the DG hunt at the time.
