    9.3 x 57 load data

    There is not much data for the 9.3 x 57.
    So this is some of what I have found

    https://castbulletassoc.org/blog/art...7-mauser-loads


    https://loaddata.com/Cartridge/93x57...Husqvarna/1018


    Handloader Magazine - February 1987 - Issue Number 125 … has an article on the 9.3 x 57

    Found a 358 Win load for a 275 grain bullet in the Lyman #45 manual for H335 - These will work as starting loads.

    9.3 x 57, now I have 4 of them....
    3 L46 and one M98. I think it is a disease.
    And I have settled on IMR 4064 as it is currently obtainable here
    The max load as published by Handloader #283 seems to have the most potential with no pressure signs.

    The Husqvarna M98 took a Leupold M96 rear base and a Leupold FN M98 front base.
    Being a hoarder pays off, Now I have a FN M98 rear base and a M96 front bace set that probably does not fit anything.
    Trying it out with Cast 200 grain 0.366" bullets later today.
    Some of the Husqvarna bores will require a 0.367" or larger bullet

    Please keep us updated with any load development. I've been on the fence about the .358 Win or 35 Whelen, then not long ago I read about the 9.3x57 and wanting to learn more.

    10X is right, certainly about my 9.3 husky. First I had to thin the necks of some cases. For the bullets I shoot them unsized, running them through a .370 die just to seat checks and lube. Can't argue with the results!

    You may want to consider the 9.3x63...
    Possibly the inspiration for the 35 Whelen. The 9.3x63 was around before the 35 Whelen

    you are spot on about thinning the necks of cases.
    A 0.367" bullet with reformed Federal 30/06 brass will not chamber without thinning the neck wall.
    I use the neck thickness of 8x57 Gevelot brass reformed to 9.3 x 57 as a minimum neck thickness standard.
    I put the Gevelot brass in the trimmer and adjust the cutter so that there is 0.001" or less between the cutter and the neck, then I trim all of the federal brass to that thickness.
    This is using a Forester Case trimmer- and forester parts are extremely difficult to get in Canada. The forester system works but is slow and care must be taken while trimming.

    Any suggestions and systems for thinning necks would be appreciated.

    What has me thinking the **x57 case is it is the middle of the road between the .358 and 35 Whelen, and that is just were I want to be. I know you can load the Whelen and 9.3x63 down, but the **x57 is something interesting.

    Husqvarna made these guns in in two actions, the model 96 - the Husqvarna model L46 and the M98. I think the M98 has a great deal of potential as it is a 50,000 cup plus action while the L46 is usually loaded to 40,000 cup or less.
    I know that I have no signs of pressure using 358 Win loads for 285 grain Privy Partisan bullets and IMR 4064. And some of the cases are on their eight or ninth reload with no signs of case separation.
    Others may have different results.

    BTW: my M98 Husqvarna has NOT been shot much. It has butt plate rather than a recoil pad. Recoil is somewhat sharp....

    And I have discovered all 30/06 brass is not equal when reformed to 9.3 X 57.
    8 x 57 brass gives no problems with neck thickness and 0.367" powder coated bullets can be loaded and fit the chamber nicely.
    Some brands of 30/06 need to have necks trimmed as they don't allow a 0.366" bullet to be chambered and have rather thick brass in the part of the neck reformed from the shoulder of the 30/06

    So out will come my Forester neck turner that came (unused) as part of an estate sale.

    The guys at the nitro express forums have loads of data for the 9.3x57 especially with the Privi Partisan 286 grain round nosed bullet at 45 grains IMR 4895. Remember the original velocity was approximately 2000 feet per second. A slower powder may give you a few more feet per second. But if deer hunting I don't think they will notice. And the max pressure level is 40k. And some of you will be loading that cartridge in the Swedish 1896 action which is a lot less tolerant then the 98 action such as the 148 series. Hope this helps.

    I know that's a typo samari, you have to mean 286 gr. Prvi bullet. I bought a couple hundred of them right after I got my 9.3 X 57 Husky. Seem to be good bullets and they certainly shoot well in my rifle.

    10x, any neck turner I've used was not nearly so quick or accurate as thinning necks on my lathe. Even using the lathe, as you said, a fella has to be careful. And no, -06 brass is not equal. All the makers are different at some level. I necked down some Lake City -06 brass and it was THICK. Made for good cases but it was more work than necessary. Generally I am not a Remington fan but I have found their -06 brass to be the best to form from....so far.

    Sharps4590, thanks for the heads up, sometimes the arthuritus (spelling) doesn't always cooperate with the eyes. I've slugged my 148 which is the 98 mauser actioned version and that was an eye opener. .370 in the throat. Slight frostiness in the bbl but as yet haven't shot it. Have to glass bed the front receiver ring and the tang as mine has no recoil lug like a standard 98 mauser. Mine dates back to 1928 as one of the members on the gunboards forum looked up the serial number. Frank

It should be easier to form Federal and Remington are probably the softest brass out there. Do not use them in your M1. The primer pockets will enlarge giving you loose primers and possibly slam fires.

    I have formed 9.3 X 57 from Federal brass and have discovered the necks do need trimming if I decide to use a 0.367" or larger cast bullet. Brass thickness goes from 0.012" at the mouth of the case to 0.015" where the case was swaged down to make the neck.
    My solution, expand the necks of my formed brass to 0.41", build a mandrel that is 0.41" for my forester trimmer, neck trim the expanded brass, then run it through a 9.3X57 die again.
    Next batch I do I will be including this step.
    I anneal the 30/06 brass, trim it to length, use a 0.338" button to expand it, then a 9.3 X 57 die to form it.
    I will be adding expanding the brass to 0.41" neck trimming, annealing, and then running it through the 9.3 X 57 case again - making sure I have the die backed out enough to give me minimum head space.
    Annealing brass is simple - A propane torch, a pan of water 1.5" deep that keeps the case head cool, heat the cleaned brass until the flame gets a yellow orange tinge - about 5 to 8 seconds, Do this in a room with low light and you can see the brass change colour - the colour change will move down the neck. When it is about 0.25" (1/4 inch) below the shoulder move to the next case. Some folk will knock the brass over into the water to cool it quickly. I have found that is not needed.
