9.3 x 57

[Hornet37]

Any information on load data and Bullet manufacturers is very welcome.

Husvarna L46 made in 1942
I am looking for a 0.366" bullet of 200 grains. I already shoot a cast bullet (Powder coated) but would like to find a commercial hunting bullet that can be pushed to 2350 fps or so.

Several companies produce 9.3mm bullets and factory ammunition. Swift, Barnes, Hornady, Lapua, Woodleigh among others produce bullets. Google is your friend here. Jacketed SPs or 'solids' are usually in the 230-286gn range because they suit both cartridge and likely quarry species - 9.3mm is a popular calibre in Africa and in Scandinavia for larger species. The 9.3X57's one-time popularity in Europe and among European settlers in Africa goes back to its being based on the 7.92X57mm military cartridge and therefore facilitating production of modestly priced rifles using the 1898 Mauser action. Its 9.3X62mm bigger brother is usually preferred though for larger animals such as Scandinavian moose. Both have modest ballistics and that in fact is why they work so well, especially in the first half of the last century before fancy monolithic, twin-core and bonded core designs appeared - a heavy slow 286gn RNSP cup & core penetrates massively on large tough African plains game and Scandinavian moose that can run as heavy as 1,000 kg whilst holding together and expanding fully.

You might look at Hawk bullets. They work great on game and we're very accurate in a 405 winchester. The 285 grain soft points in prvi factory ammo in 9.3x62 work well on deer and would probably do good on elk.

If it is not very expensive I would rechamber for 9.3x62 a much more satisfactory cartridge:components are also easier to find at least in europe.

You may have to search for a 200 grain bullet in 9,3mm; they seem to start at about 230 grains and go up. Graf's has a pretty good assortment, but no 200 grainers. Same with Midway.

Neither company ship to Canada... Sadly.

Then there is the bigger, bigger brother...

Not only was this cartridge popular for African hunting but the cases, available from RWS, were used to produce several wildcats at the time I was working with the cartridge. The examples from Nosler are typically under powered and they have the wrong case capacity. But typically we would achieve 2850 fps at moderate pressure using the Swift 250 gr. A-Frame from a 26" barrel. This was a favored cartridge for the M98 Mauser conversion because the bolt work and feeding work was fairly simple.

that is very close to a 06 case. did anyone ever neck up the 30-06 case to around .39/ 9.3? I think I remember a round a little over 40 cal with the 06 case

There's a .375 and .400 Whelen; been around for a L-O-N-G time. Also a .416 based on the -06 case. The 9,3mm is .366", FWIW.

No, it's not - look at the case dimensions. The 9.3X62mm IS very close to a 9.3-06 (only as it preceded the 30-06, you could argue that's not the right way round! )

The 9.3X64mm Brenneke - as introduced to the thread by @Kurz - is a substantially larger / higher capacity number than those cartridges based on the 30-06 or the 9.3X62mm (which were based on the 7.9X57 and 7X57mm Mausers). Whilst the 7.9 Mauser and those subsequnet numbers based around its case-head design use a 0.473" case-head and lower body diameter, the 9.3X64mm is 0.496 dia at the case-head and 0.507" above the groove. Its capacity is ~88gn water compared to ~68gn for the 30-06 case. At 88gn capacity it has a marginally greater capacity than the 338 Win Magnum (85gn).

The Brennecke design dates from the late 1920s and was introduced to challenge English cartridges like the 375 H&H Magnum (95gn water capacity) whilst remaining short enough to fit a standard M1898 Mauser action with only magazine box alterations and a bit of extractor fettling needed. It was (still is) a very effective design and was immensely popular in Africa for many decades.

The nearest thing you'll find to a factory provided larger calibre necked-up 30-06 of that pre-WW2 period is the Westley-Richards 318 Nitro Express introduced in 1910 and which uses a 0.330" dia. bullet and is easily mistaken for a heavy bullet 30-06 loading at first sight. (That's how I found my first few - they came in a large box-load of junk surplus mixed origin 30-06 M1 and M2 ball rounds dating from the 1920s to 1945. It took me a minute or two to realise this was a different cartridge not an unusual '06 loading.)

on the nosler page above it says the 9.3x64 holds 73 grains of water not 88. there is no way that case which is close to an 06 case can hold 88 grains of water

 

[Laurie]

Nosler's water capacity figures are those for usable capacity with the bullet seated at the quoted COAL. (If you look at Nosler loads tables for any cartridge you'll see a variety of quoted capacities depending on the bullet being loaded.

The 9.3X64 value comes (as do the 30-06, 375 H&H etc) from QuickLOAD whose compiler generally uses actual brass samples. This is an overflow value, ie the case filled with water level with the mouth. (The program reduces the available volume in its calculations after the bullet model and COAL are selected to obtain the usable volume for the powder charge.) Since all cases are measured the same way, the results are comparable.

In the Nosler data case, Nosler quotes COAL as 3.345" with the 250 Spitzer and Accubond. Input the latter into QuickLOAD at that COAL and the program says the bullet occupies teh equivalent space to 14.691gn worth of water retaining the volume of 73.313gn water for the powder charge (then converted to the more usual CC measure for pressure / velocity computations). Same as Nosler quotes, QED. The 30-06 'overflow' value will be reduced by an equivalent amount with say a 180gn bullet loaded to SAAMI COAL.

It may surprise that the Brenneke case holds more than 30-06, but if you compare cartridge drawings you'll see that its nominal case-body diameter at the shoulder junction is 0.474", ie one thou' greater than the 06's case at the rim/bottom of the body, and over 30 thou' greater than at this point. For a 1927 design, there is remarkably little body taper. Also, the case-head to body shoulder junction is just over an tenth of an inch longer for the Brenneke.
