Does anyone have a load for this cartridge with a 200gr bullet.All help will be greatly appreciated. Thanks Dave
This won't be much help, but it's all I have. A German site,
www.ladedaten.info, once posted some purloined RWS data for European Rottweil powders using Hornady .358 bullets (I forgot to record which ones, but I think both were RN):
200 gn 3.03"
R 901 42.5 2200
R 903 50.0 2165
250 gn 3.11"
R 902 43.0 2035
R 903 47.0 2035
Starting loads were 2 gn less. These appear to be conservative data, perhaps due to using modern .358 bullets. Original hunting loads were, I believe, about 250 gn at near 2150 fps. I don't think RWS powder is available in the US. You might be able to find some near equivalents using a burn rate table, but that's risky business.

vapodoghere's one
200 Hornady (.358) IMR IMR-4320 46.0 2,150
I have a little more loading data but this is all with the 200 grain bullet.....this one is hard to find data for,.

dave sorelThank you all for the info. Factory Kynoch were 245gr.I am using the 200gr 358 sierra rn because I think it is on the soft side and would cause less pressure in the slightly smaller 9mm bore Vapodog I am going to try the 4320 tomorrow I'll post what happens.
Thank Dave
Dave:
Just a thought. You might want to consider trying North Fork bullets in .358 caliber. With their driving band design, these might cause less pressure in the 9x57mm than conventional .358 caliber bullets.
They do, however, have a solid base but the driving bands may offset it. Might be worth a call to Mike at

jeffeossoTHIS MAY NOT BE SAFE
i am a 358 win loader, so I have had quite a few loads for that...
when presented with a 9x57, I just used the SAME 358 win loads as starters, knowing I am going to give up ~200fps, but since the x57 case is larger, the pressure is lower

dave sorelThanks guys I'll try both

I should have noted earlier,
Hawk makes jacketed bullets of the correct diameter(s): .353, .354, and .356. The reputation of these bullets at high speed is poor, but shooters of slower speed rounds often report success, and the 250 RN in the 9x57 is not high speed. If you try them, you may want to mic your bullets received; one user (and so far only one user) here reported quality control can be spotty.
Lastly, QuickLoad suggests powders similar to Reloder 15 can produce 2150 fps for 250 gn bullets while staying within CIP pressure limits.
