Nyati (n-ya-te) means Cape Buffalo in many African languages such as Swahili. The .585 Nyati can generate Auto ft.lbf|10000|-2 of muzzle energy. This places it at or near the top of the list for most powerful cartridges that can be chambered in a rifle that can still be carried afield.

History

The .585 Nyati was developed by Ross Seyfried. He was motivated by the desire to create a rifle with tremendous stopping power at a fraction of the cost of expensive double guns such as the various Nitro Express rounds. [ [http://www.470mbogo.com/BigBoreCompendium/#585Nyati Historical .585 Nyati Information] ]

The rims were turned from .577 Nitro brass and the case blown out straight to allow formation of enough of a shoulder for headspace purposes. Brass formed by this method, during the developmental phase, had a relatively weak case head due to the fact that the parent .577 Nitro case was designed for a double rifle which supports the case head all the way to the rim. In a bolt action rifle, a portion of the case head is unsupported and requires more strength in that area.

Recoil

Sensible weights for a .585 Nyati range from 12 to Auto lb|16|0. Recoil in a Auto lb|12|0 rifle would be severe. Auto lb|10|0 rifles have been built, but the recoil from full power loads would be very difficult to manage, perhaps impossible for most shooters. For example, typical bolt-action hunting rifles weigh 7-9 lb when scoped. [ [http://www.chuckhawks.com/rifle_weight.htm Rifle weight] by Chuck Hawks] In typical calibers such as .308, .270, or .30-06, recoil ranges from 15-20 ft·lbf. [ [http://www.chuckhawks.com/rifle_recoil.htm Rifle recoil] by Chuck Hawks] By comparison, a Auto lb|12|0 rifle in .585 Nyati using a 750 gr bullet at 2466 fps would have Auto ft.lbf|158|0 of recoil.
