I ordered a 9.3 x 57. Anyone know of a good bullet mold for such?

I found some 270 gr cast bullets with gas checks for sale. There are a few sources of jacketed bullets. Speer and Nosler make such bullets. I have found a few loads for the rifle and I guess Norma reloading manual has it listed.
Bullet molds and gas checks and reloading data are fairly scarce. I think I will be working on the rifle this summer as my project for the summer.

and a Vernier sight. It's marked up to twelve-hundred yards. This one shoots a mite further.

Now I'm not familiar with the cartridge but I would guess it's just a necked up Mauser case?
Which firearm manufacturer is building the rifle you just ordered and what do you intend on using it for if you don't mind me asking?

A few friends and I have ordered 10 former private sporting rifles out of Germany at a decent price. The one I selected is a 98 Mauser action. We are sort of buying pig in a poke. However, I am highly hopeful.
The 9.3 x 57 should be a little more powerful than a 358 Winchester as it has a slightly larger case and a larger bore diameter. The Loads I have seen go up to 50,000 psi - I assume that is measured electronically rather than the crusher method.
After taking a chamber cast and slugging the bore and making a careful inspection, I think I will start with IMR 4064 and the Speer 270 grain bullet with loads about 15% lower than I have seen published. I will work up until pressure signs start to show. A chronograph will be used to aid in loading.
I am also going to order some cast bullets with gas checks and try to determine if 2200 fps might be possible.
I suspect that it would make a good deer and larger game rifle at close range.
For cases I plan on using 8x57 necked up.
These days I spend a lot more time shooting at paper and steel than at game. I applied two places for elk tags but those are hard to get.
I bet that with cast bullets or Speer 270 grain bullets it out to bring a deer down.

I'm guessing 9.3 is real close to .357?
And on the 8x57 case .
My guess it should be a perfect match for close range Deer and Elk. Real close to Jack O'Conners .338X57 which he determined to be the ideal close range cartridge and pushing the same weight range of bullets.
As I recall the 9.3 has been popular in Northern Europe for a long long time, for Moose and large deer. Kind of odd it is nearly unheard of in the states.

Sounds like a fun project to me. I think it would be quite useful on a Black Bear nunt with hounds where you know your shot would be close and you would have plenty of energy too.
A cartridge like that wouldn't need a long barrel in order to produce the velocity like our more popular higher capacity cartridges so popular today with most shooters. I'm not entirely sure IMR 4064 will be quite fast burning enough, but that's just a guess on my part as I don't have any of my loading data available here. Sounds like the project will be a heap of fun to play with..

That does sound like a neat project!
If I remember right, 9.3 corresponds to .366

I think your right Jack. .366 popped into my head on the drve to work this morning.
I can't remember where I stumblrd onto it but remember reading of SCANDINAVIAN OR SWEDISH HUNTER hunitng in either Alaska or Canada with a 9.3 Double rifle, said it was the only rifle he owned and it would drop anything he had ever hunted.

1 inch equals 25.4 mm exactly. Sooo to get the diameter of the barrel divide the size in mm. 9.3 by 25.4 which = 0.366 according to my calculator
I tried 6 mm and 7 mm and 8 mm and I expected .244, .284, and .323 but I it did not come out that way.
Then I thought back to some of the old cartridges such as the Newton etc.
It seems some barrels are measured by the bore diameter and some are measured by the lands of the rifle diameter.
It would make it too simple if it were .358 (which is approximately 9 mm) as there are lots of bullets and moulds for the .358.
If I can get a hold of a digital camera I will post it when I receive it and get pictures.

9.3x57 Mauser is a rimless, necked case and is based on the 8x57 Mauser Dates back to 1900 or earlier and was used in both Mauser &mannlicher sporting rifles. it is about the same class as 358 WCF & 35 WCF. bullet grs. 232, powder/grs 3031 47 , MV 2330 , ME2785.........bullet grs, 286, powder/grs. 3031 43, MV 2070 ME 2705 Both are Norma bullet & load.

Bounce, Thanks.
I am not familiar with Norma powders. Is their 3031 similar to IMR3031? slower/ faster?

I can't tell you? I just took this from Cartridges of the world.

I don't recall any Norma powder with a number like 3031.
My guess is that Norma was listing loads using several different manufacturers powders, like IMR-3031.
That's just my guess, though.

Well that will help. It seems that IMR3031 and IMR4064 are about medium burn rates. Perhaps H4895 and IMR4895 would work well also (& W748).

I think your going to find that the 9.3X57 is a great rifle to play with. Most of the 9.3's are some really heavy hitters. Kind of like the .375's. Maybe not a long range cartridge but out to 300 yds it will be a hammer. Awsome close range Moose and Bear cartridge. A guy I use to deal guns with was a guide at one time and always used a 9.3X74 double rifle as his dangerouse wounded bear gun. If a person wounded a bear and it got into the really thick stuff they would get him and his 9.3 to go after it. He said it really does a job at 5' on a griz. I suspect that a bear would be hard pressed to tell you the differance in how hard either of the 9.3's hit  Their a hammer. |
