I wonder who has the power to stop Rigby 416, compared with 458 Lott. In particular I want to ask whether the property with 416 Rigby kills an elephant, an African buffalo, a rhinoceros or a hippopotamus that burden against the hunter. I know that if Lott 458 overthrew these dangerous animals with solvency. On the other hand, I can tell you that I have a 375 H & H Magnum, what size you buy in my case? Thanks and forgive the inconvenience.
