For the animals you would use the rifle on, the .257 seems fine for the smaller ones, but a little light-on for the eland. The .416 Ruger seems fine for the eland, and much bigger than required for the two smaller antelopes. I happily use my .416 Rigby on smaller animals, but they do have to be closer. Short of getting a happy medium, I'd be leaning toward overkill. Mind you, I have no African experience other than what I've read, just Australian experience.

All the best with the cat, too! I look forward to reading about it in DGM. BTW, do you know when we might be able to subscribe to DGM?

Cheers,

Ben
