Thread: 9.5x57 Mannlicher Schonauer

To me the 9.5x57 looks like an 8mm Mauser case blown out to seat a .375 bullet, with only a little shoulder.

Can't find any actual reloading data anywhere, but building on what the previous owner had done I have fired and chronographed the following loads:

235 grain Speer with 42 grains 2207 = 1996 fps (looking for 2300 - 2400 fps)
235 Grain Speer with 52 grains 2208 = 2000 fps ( "" )
270 Hornady SP with 50 grains 2208 = 1965 fps (looking for 2150 fps)


All very mild, rounded primers, backed out a bit. Very low pressure looking. Mild recoil.

Anyone use any other powders/ bullets? So far the Speer 235 grains feed perfectly in the spool magazine, but the Hornady spitzerswill jam it up.

I was just going to keep putting powder in until I get the velocity I want or it looks like I am getting some real pressure signs. Any thoughts?

Greetings @JohnDuxbury,
You lucky devil. The 9.5x57 has fascinated me for ages but I have never even seen one. Frank Barnes listed 44 grains of IMR3031 for 2,150 fps in an old COTW. He also listed 47 grains of the same powder for 2,330 fps with the 235 grain and 43 grains for 2,070 fps with the the 270 grain in the very similar 9.3x57 Mauser. I will see what else I can find and post later.
