Someone might share the balistics on this round? 9.3x57. And its history? Why was it chambered in a 96 mauser in lieu of a 98? I would have thought the 98 would have been the way to go....???/

9.3 is .366/7 am I correct ? and the case is a blown out 8mmx57?

This round is new to me...any info appreciated.

Hi Exit!

the 9,3 is .366 that is true and the fact that 9,3x shares the same body as the 8x57 is also true.

The reason for a 9,3x57 in the 96 rifles is that it´s a lowpressure round with lots of charm.

In sweden it´s a typical moosecaliber that sends a 232 or 286 grain bullet down the path.

If you have one make sure to get Norma cases and remember if it´s a Husqvarna that they can be liberal to say the least regarding size in the chamber.

Best regards Chris.

The 286 gr bullet loads to about 2000-2100 fps, the 270 Speer about 2100-2150, and the 250 gr ballistic Tip (discontinued but an Accubond version is comming) about 2250.

It's a very mild-shooting, heavy bullet round with lots of killing power. Cases are availble from Norma or you can run 8 x 57 cases in the sizing die and go shooting.

The Swedes made tens of thousands of them on '96 actions. For a while in the 30s it was the only sporting round chambered in Husqvarna commercial rifles.

What kind of pressures/volocity could you expect from a 98 action?
I've got a yugo 24/47 that I haven't decided what to do with.This could be an option if I can find a good barrel.

Chris, I have a Husky 146/ m98 arriveing next week. Whats the scoop on the "liberal chamber size"?

On the 9.3 x 57, the pressure limitation will be the brass regardless of the action. Just like you can't run 62,000 psi in a bolt action, neither can you run thin 9.3 x 57 brass to 300 Win pressures.

Huuhh? What?

Affectionately known in Sweden as the "potato thrower". Don't let the moniker throw you, favored as a moose killer that gets the job done very effectively without a lot of recoil or meat damage. A nifty old round in a Husky bolt rifle, Tom Kessel has one he just sold on Guns America if you want to see what one looks like.

I had no idea the 9.3 case was weaker or thinner than 8x57 cases which I would be using anyway.
I load the 8x57/250woodleigh to 2300+ with H4350.The load came from woodleigh and is a safe load in my rifles.
It would seem to me that the 9.3 using the same case, bullet weight,and pressure levels would generate higher volocities and energy.
Were am I going wrong?

Yentna River,

You hav eto remember that in factory trim this is a low pressur eround designe dfor us ein the 96 action, as susch Norma loads to 36,000CUP and their reload data goes to 46K. I interpet your question to mean, if overloaded in a 98 what velocities can you expect. Well, I'd look to the 8x57 vs 8mm-06. Loaded to the same pressures as the 9.3x62 which is similar in capacity as the 8mm-06 you can get within probably 100 fps. It would be easier to get a 9.3x62 unless you already have a 98 chambered in 9.3x57.

I like it as is, 285's at 2100 fps or so. When I want more I drag out my 9.3x62.

With case capacity falling between 358Win and 35Whelen and with a slightly larger bore it sould come very close to 35Whelen when loaded to its potentual in a mod98 action.I would expect 2400+ with 250gr bullets would not be hard.

No way you can safely get this out of a 9.3x57. You must be thinking of the 9.3x62, which easily exceeds 35 Whelen ballistics.

I get 2550fps from my 35whelen, 57gr IMR4320,250gr Hornady SP out of a 22in barrel.The same 250gr bullet can be loaded to over 2300fps in the 358Win.
Since the 57mm case capacity falls between these two and the bore of the 9.3 is .008 larger,why wouldn't we expect the vol. of 250gr bullets to fall between them as well?

Point well taken, Steve. A standard .358 rifle can push a 250 grain bullet at 2390 fps and that's with the bullet eating up a lot of powder room( initial volume). That restriction disappears with a properly magazined and throated rifle.Vis-a-vis, .244 (6mm) vs .243, 6.5x57 vs .260, 7mmx57 vs 7mm-08, etc. The heavier the bullet the greater the disparity between any of the two comparisons or contrasts if you will. roger

Ok so next question. Is it possible to re-chamber a 98 action in 9,3x57 to 9.3x62? using the same barrel that is? I this worth it? I'm thinking lobbing 285 grainers at a true 2500fps.

???

At that speed your not really lobbing them anymore are you?

Yeah, that came out wrong. I meant you can't run 62,000 in a 30-30 case when it's in a bolt action, and you can't run 62,000 in a 9.3 x 57 either for the same reason (thin brass). I know because I tried, LOL.

It was a pretty common conversion; just a reamer job. Some of the earlier '96 and '98 Husqvarnas in 9.3 x 57 had "9.3 MM" on the barrel with no length markings so you didn't have to remark the barrel when it was reamed to x 62.

For that reason it is always recommended to make a chamber cast on an old Husky marked "9.3 MM" to be sure it isn't rechambered to x 62 before you assume it is still a 9.3 x 57 and fire a short round in it. All the 9.3 x 62 factory Huskys were so marked on the top of the barrel

Exit31,

In a standard length 98 action it makes perfect since and is done quite often. A 286gr bullet at 2450fps is what you get from the 9.3x62.With good hand loads a bit more. Unfortunately, mine is a Yugo 24/47 (intermediate length) action.
