Thank you Mr Rahman, Unfortunately I think it wont ever be the case, but it is nice to dream of an era when those ideas were possibilities. The .458WM I mentioned belongs to my father & has become his favorite, my exposure to it has certainly started a keen fondness of it, but I have my own rifles which I have come to appreciate and fancy to have on an adventure. The 9.3 x 62 is an all round rifle I cannot fault but it does have its limitations. Mine is used for small to medium & certain large game (Warthog, Impala,Gnu Kudu, Eland ) Guar I know very little about, but my preference would be my scoped .404J. in recent times I have come to adore this caliber for just about all game as a result of its moderate velocities, but can do everything the 9.3 does & more with perhaps exception to be able to take longer shots, but my comfort levels are to 300m & less for plains type game & usually for the pot, to which I have better suited rifles to choose from. For the thickets where dangerous game is to be encountered at close ranges of 40M & less, I would gladly carry my 470Ne or 450/400Ne where a scope is not ideal. This probably explains why no diversified hunter can be satisfied with only one rifle and not a single caliber can truly be the ultimate best for all purposes & situations.
