It is suitable for any game that an expanding 458 should be used on. From Alaskan bears and moose to the largest African eland and Cape buffalo. I have reached 2300fps from a 26” 458 Win. Mag. and the bullet is nowhere close to failure. I don’t actually know what the upper limit of the bullet would be but I do know, for sure, that I don’t want to fire the gun that could generate the kind of velocity needed to find out. The Lott should be capable of 2400fps and would put the bullet in the center of its operating range.
