Does anyone have any first hand experience with the 9x57 mm Mauser?  Would love to hear about it if you do.

Right now Midway has  9X57 brass (one box of 20) on clearance sale for about half price.

Its allowable pressure is 40 KSI, so even though it's bigger than a 358 win it's performance is slightly less. Of course in a modern made rifle it could be perked up to do about the same thing as a 35 Whelen. Just depends on the rifle it's chambered in. Even at less than 40 KSI it'll certainly take care of anything that needs shooting within reason.

Back in the day I had a nice German Greifelt sporter made up on a commercial Mauser action. Made cases from factory 8mm brass. RCBS dies were employed. As it happened the grove diameter was .362  but gave good hunting accuracy. The cases needed to be trimmed to be satisfactory in this rifle. The proof marks plainly stated the rifle was a 9x57 which is another story.  My loads at the time ran 2200 fps. using 250 gr. Remington bullets and IMR 3031. Did care about pushing this rifle since the scope mounts were dovetailed into the receiver.  In this day I would consider the cost of dies and the benefits over .358 Winchester or .338 Federal.

I had a beautiful little guild-made German rifle with all the touches.  I read they were made for the Germans in Africa between the wars.  The cartridge doesn't get a lot of respect and is certainly not recommended for dangerous game, but I had a blast reloading for it.  I carried it a few times for deer but never got to use it.

I had good results with all the faster IMR powders, 46 gr 4064 gave me 2100 fps, 43 gr 3031 was good for 2070, both with the 250 gr Hornandy.  I got a 240 gr gas check mold and loaded 45 gr 4064 for 2185 fps and 42 gr 3031 for 2120.  I had some 245 gr Kynoch factories that gave around 2250, although one sounded wrong and only clocked at 1415.  Hmm.

You can shoot pistol bullets but they wont be accurate.  I was determined to try and I built a crimp die by drilling out a piece of wood to accept the front of the cartridge, then drilled a small hole coming in from the side, put a decapping pin in and tapped it with a hammer 3 or 4 times around the neck just below the base.  I think my brass was 8 m/m, worked fine as I got it, but the previous owner might have worked it in some way.  Congratulations on your new toy.

Also shot some of the 9x57 Kynoch factory ammo. Stopped shooting it when one case split length wise through the head and primer pocket. No damage done but that ended shooting that old factory stuff.

Most of the Cablea's have a few of both the 9x57 and 9.3x57 in nice older mauser actions. They sure come up nice to the shoulder. They got a bunch of them from Sweden when they change the tax laws on guns. They are marked Carl gustaff and Husquavarna.  Really nice smooth actions

Howdy, Mine is a Greek 98 8x57 that I had Delta Gun Shop simply rebore to .358 w/ no other changes to the chamber ect. It is a wonderful ctg. as I simply use 8x57 cases, a set of 9x57 Redding dies and any .358 bullets. W/ the Lyman 57 reciever sight and a bead on the front I have a simply wonderful wet/beater woods rifle. I have even left the mil. rear sight (w/out the ladder) and front band on but may recut the front base dovetail to a standard 3/8" so I can have different front beads ( there are few mauser size dovetail aftermarket beads available now). I use any 358 Win loads and most minimum 35 Whelan stuff w/no problems. I found a LOT of 8x57 mil ammo a few years back (Turk Berdan) and pulled the bullets, ran them over the 9X expander ball and seated .355 Speer 125 RN SP (also 200 grn RN)  over the Mil. powder/primers and they shoot just fine (saved the 8mm bullets for my BNZ 8X). Works really well on the local varmints! I usually use 250 Horn. RN's for serious work but mostly shoot the 200 gr. RCBS 200 gr. GC at about 2000 FPS for banging around. I wouldn't hesitate to have one bored for the 9.3 (.366) or the 9.5 (.375) either but would probably go for the 9.5 as there are more bullets/molds available. Be careful my friends!-Muddy
