Yeah, I didn't know the species. I'm just giving my own experience, which is heavily whitetail-centric. Everyone's mileage may vary.
I will say this: I was very surprised with the lack of a demonstrable increase in performance. For all the extra recoil, you'd have thought the deer would be dropping over just pointing the barrel at them. This was not the case. I'll also mention that I'm shooting a downloaded .308 WIN load that's more like a 300 Savage. I could add quite a bit of velocity before MAXing out.
I hear ya. Dead is dead, and a .458 WM won't make 'em any deader. For all we know, a .257 Roberts might have dropped those whitetails even faster than the .308, but I consider the .308 an excellent choice. I bet it leaves more good meat behind than the Bob.
Cheers,
Rex
