This has already been addressed, but... .458 Win Mag as a Dangerous 5 rifle?

The main point is this. If a good bullet is driven by a good powder that was ignited properly, it will perform as it should irrespective of the case's headstamp.

david little owns kynamco and has the the rights to the use of the kynoch name. he started loading a lot of the old british calibres including some obscure ones and gave them a new lease of life. he does load a few "new" ones as well, but you are basically talking about two different companies, with the old kynoch then owned by imperial metal industries stopping loading sporting ammunition by the late 1960`s to early 1970. which is why winchester developed the .458 to replicate the performance of the .450/.470 nitro cartridges, along with the fact that americans were starting to go hunting in africa in increasing numbers and needed a reasonably priced big bore rifle/cartridge combo . unfortunately with the problems with the powder this didnt happen and led to the bad early reputation of this cartridge, but with new powder developments the problems were cured.

Thanks for the education. I wasn't aware of all this. I don't think I have seen any Kynoch ammo since 1970......now I know why.

If compare the .416 Rigby with 400gr. DGX bullets at 2415 fps/5180 ft-lbs to the .458 Win with 500 gr. DGX bullets at 2140 fps/ 5084 ft-lbs there is not much difference.

if you look on the kynoch/kynamco website it shows you the distributors round the world, so if you need some you should be able to find it.

Doubles, Loads & the .458
This is an excellent article that explains the problems the .458 HAD and sets the record straight about all the old rumors surrounding the .458.
It is very interesting and informative.

Totally agree.
The bullets I talked about in my other post was soft points.
