9x57 Mauser

[mbogo3]

Just came into possession of 6 10rd boxes of Kynoch 9mm mauser ammo. Looks kinda neat somewhere between .35 Rem and .358 Winchester in HP. Common back in the day in Africa for game zebra size and smaller. I've only know of two guys that actually had rifles in this calibre. I think these are 245gr at 2150 fps?

9X57 Mauser ammo was also used in the 1905 Mannlicher Schoenauer. This was the only year that the MS rifle was made in that calibre. Older Lyman reloading manuals (#39 and earlier) list loads for it, listed as "9m/m Mauser, Mann.-Schoer." Google tells me that Remington and Winchester also made rifles in that calibre. 9X57 is now considered semi-obsolete. Brass is easily made from 8mm Mauser brass. Lead bullets can be cast from Lyman 358 315 (204 gr.). Don't know what jacketed bullets are available. Interesting ammo. particularly the unusual tight shoulder.

I experimented reloading this cartridge once using resized Hornady 250 gr. .358 dia bullets resized I think? and 4064. Never got around to measuring the speed, but I recall accuracy was mediocre but recoil was harsh. No signs of excessive pressure. I will need to re-vist that again since a finally bought a Labradar after shoot'in my chrony. I have some factory I can compare as well.

Here's a bad copy (of a copy) that I used. Redding Dies were used.

an old friend has a fancy Mauser rifle with an extra 9x57mauser barrel

it would fit a m96 receiver

I tried to get him to sell it to me, but to no avail. This was many years ago. perhaps I should ask again!

I ended up with a 9.3x57 and x62 instead
