Can anyone tell me where I can find reloading data for the 9x57 mauser and the 9.3x57 mauser? I have stumbled across two of these rifles and want to add them to my Classic African rifle collection. I realize they are short to medium range calibers for plains game and would like to use them on my next Safari next summer. I hand load for a 8x57 and 9.3x62 so I am familiar with handloading. If anyone has experience with using .358 bullets in the 9x57 any information about this would be appreciated since .356 bullets are hard to find.

Thanks,
David Brown

The 9.3x57 is new ground. I have found a few recipes that will probably show up here and one that I have worked with.
Mine is 48 grains of Win. 748 in 8x57 cases with WLR primers behind a 250 grain Nosler Ballistic Tip. It shoots under 1" in my rifle but I cannot attest to the pressure but appears safe in my rifle.

I have had and shot a large number of 9x57 Mauser sporters over the years...all from the years when German East Africa was a thriving community and when they were commonly retailed in places like Nairobi to the local settlers/farmers.

I fired them a lot with both DWM factory loads, and my own 250 gr. handloads. I used only .358" diameter bullets in my handloads, but had no trouble duplicating the accuracy and trajectory of the factory loads, with no signs of excess pressures.

I am sorry I can't fish out those loads for you from my data, but I sold my last Commercial 9x57 in 1975 and the info has long been buried in my stuff.

I have the cabinet-makers coming today to give me a bid on cabinetry for my new workshop. Once I get the cabinets all up, I can start sorting out those records.

In the meantime, I would suggest looking in COW, and/or running the cartridge on Quik-Load for some starting data. Or, you can do what I had to do back when I started loading for it; Begin with starting .358 Winchester 250 gr. bullet loads from your current manuals, and work your way up

Welcome to the realm of the potato chucker, what the Swede’s affectionately call the 9.3x57. I have an old Husqvarna model 46 rifle, which is based on the Mauser 94 action. I hand load very conservatively for the rifle since its 77 years old and don’t want to stress the old gal. Hope you have fun with the old cartridge. In power level the 9.3x57 is about equal to the 358 Winchester.

Here are some links with loads (note: the last link is probably the definitive work on the subject):

Not to say the 358 Win is a bad round, to the contrary quite a good one, I have to disagree with you that the 9.3x57 is about equal to it. The 9.3x57 is much more cartridge then the 358 Winchester. Perhaps you meant it's equal to the 35 Whelen?

SmokinJ.

You are probably right in your assessment, but I don’t like to load to maximum especially in old guns. The 35 Whelen (based on the 30-06 case about 68 grains of water) has a larger case capacity (about 5 grains of water) than the old 9.3x57mm (based on the 8x57 case about 63 grains of water) which is more than the 358 Winchester (about 53.5 grains of water). So if I can keep the old rifle with a power level that approaches of the 358 Winchester, I am perfectly happy with it.

Setterrun, regarding the 9x57: use .358Win bullets, start with light 8x57 loading data, work up, neck up 8x57 brass.

My choice has always been, providing its a mod 98 action, is to rechamber to he 9.3x62..It is a snap to do. The 9.3x62 is one of the worlds finest cartridges and the best cartrige on the 06 size case for the larger big game and DG animals.

If the gun is a collector then one might not want to mess with it, but it would have to be very valuble for me not to change it.

I agree. I had a M96 I did that too. It turned the old Arctic potato flinger into a real pocket rocket. Since I had no use for another heavy rifle, I sold it to a friend who wanted to go elk hunting. But if I ever come across a standard length left hand action, I'll build one for my son in a heartbeat. 9.3x62 rocks!

It do Sarge, it do rock!

The 9.3x57 is good for driven game; moose and boar especially in Scandinavia.

It is one of the few cartridges that will not turn a Speer 270-grain 9.3mm bullet inside out. It is the same story with the Prvi Partizan 285-grain cup and core bullet.

One word of warning regarding the 9x57 Mauser. Be sure to carefully slug the bore. It can, and they do, vary between .354" and .358". Lee will sell you a custom swage die for less than $20.00 that will swage the bullets down. Never go more than 0.002" or 0.003" at a time. It is much better to run it through two different swage steps than bite off 0.004" at one time. Even if you can get it through the die, the bullet will spring right back up at least 0.001" to 0.0015".

Check the Norma book for loads. The loads above are good (mostly), but look at then as reference, not recipes.

I used to have A Mod 98 Haquvarna in 9.3X57 as well as a 358 Win Mod 70 and now I own a 9.3X62 as well as a 9.5X57 MS. The difference between the 9.3X57 & 358Win is small - with the 9.3 being able to use heavier bullets. it is well below the power of the 35 Whelan.

You should get good results with Varget - about 2550 fps with 232 gr & 2300fps with 286gr bullets. IMR 3031 would also give you good results but is not as stable in cold / hot weather.

The 9.5X57MS also gives similar results with 235gr & 270gr .375 bullets. The rifle of course is the silken smooth gentleman's rifle - the 1910 Mannlicher Schoenauer!

I always get carried away when discussing this particular lot of cartridges and old classic rifles.

Thanks for all of the responses, I apperciate the help.
