Buds and Buddettes,

Short Question:

9.3WSM - Has anyone actually done this round?

SSGA

Not that I'm aware of . . .

I've seen a .35 cal. wildcat on 300 WSM brass but nothing at the 9.3 mm diameter yet. It sounds cool yet I wonder if the 325 WSM is the largest bullet diameter that will perform in this type of case. I had heard that Win. intended to make a 338 WSM instead of the 325 but discovered during the R&D process that the common bullet weights in .338 did not function properly due to lack of case capacity. 8mm cartridges are pretty rare in North America and a 338 WSM would have made much more sense here, so I wonder if there wasn't something to this that made them choose to stop at the .323 dia. FWIW, Remington did not pursue anything past the 300 RSAUM.

Yes, the 9.3 round has been done...

I have done the 8mm, 338, 9.3, 375, 41 cal., 44 cal. and 45 caliber on the 300 WSM case....

Thanks Assassin,

Do you have any ballistic tables on this round?

I have a 458Alpine which is the beefed up version of the 458WSM, and am looking at the Kestrel to go a little flatter in trajectory......

SSGA

The 9.3x62 or 9.3x74 would be better, but not in a SM. I don't beleive a 9.3 wsm could pass the 9.3x57. Jim

SSGA,

no Sir - I do not have any ballistic tables for these rounds. I had asked the customers that I had built the guns for to send me the reloading data that had developed and so far, I have yet to hear back from anyone. I got them started with a couple of starting loads and preferred powders but, I never bothered to chronograph any of these "starting" loads....

I believe it would equal the 9.3x64 or even 66 with readily available wsm cases.....having built a 458Alpine off the WSM case i see no reason the 9.3 wouldn't be a good choice after the 325wsm.

SSGA,
You cheeky bugger trying to avoid me. Ditch the 9.3 idea and use your Alpine case in 35cal. Lighter 200gr projectiles (to flatten trajectory) are readily available from soft (Rem) to hard (Barnes), plus 225gr (TSX and Nosler), 250gr is well represented ... and then there's Woodleigh's 310gr soft and solid for heavy stuff. Pistol projectiles like a 170gr FMJ or 158gr make perfect varmint projectiles.

Using the Alpine case ... 358Norma velocities shouldn't be out of the question as the straight 35Sambar was reportedly hot on the heels of the Norma.
Cheers...

Although not on the WSM case, there is a "9.3 BS" I believe (the "BS" being Barsness-Sisk) that was on the 350 Rem Mag case. It was written up in one of the gun mags a couple of years ago. Might be a point of reference anyway.

Hey Con,

With the New super aerodynamic 9.3 bullets out there the 360 Kestrel should easily out perform the current 9.3 cartridges and maybe take on the 338WM or 338LM in regards to wind bucking ability for the 300-400yd shots...?

I like the 35 cal but i cannot seem to find any good BC bullets.

SSGA

ssga,
Nosler Acubond not good enough? Aerodynamic and short enough not to take up case capacity will be the issue!!
Cheers...
Con

No it is good enough i guess...... but too close to the 338 to make a serious advantage claim over the wind drift and in the 366 there are two bullet weights in both Nosler and Barnes with BCs to match.........360Kestrel here i come :D

SSGA

SSGA,
Are you home yet?? If the 360Kestrel is a straight 9.3WSM ... are you sourcing reamer/dies or getting the chamber cut with a 300WSM followed by 9.3 neck/throater? Another option would be to have your 458Alpine reamer reground for the ... 9.3SSGA???
Cheers...

No it will be the Alpine case necked back down, and so as not to change the 458Alpine reamer as i have two people keen on building them i will need another reamer cut :rolleyes: this time with a longer throat......single shot 500yd toy....for use on big game ;) the reason I called it the "Kestrel"

Oh and yes i am home, the 9.3 is very popular in Europe :D

SSGA

ssga,
Okay, I see where your going.
Make sure you contact the Industek (or whatever their name is) mob that are bringing in the Russian bolt guns. Last I contacted them they were talking about bringing a few Russian 9.3x64s in, plus a few target projectiles (Russian sourced) in 9.3cal which may be good for punching paper and maybe game at long distances. Hey .. why dont you start a thread at AHN ... you chicken or something? :p
The 375/08 is also back from Shane Clancy with headspace tightened to 308Win specs ... about to start load testing again ... should keep me busy until the 458AR is built. :D
Cheers...

Got reamer diagram today........now just need to check the hip pocket.....!

The 9.3 BS is supposedly the equivalent of the 9.3x62, sayth Barsness. The 350 Rem mag case is thinner and a bit longer than the WSM case, but holds less powder. So this 9.3 WSM round would likely beat 9.3 x 62 ballistics.

I'm still wanting to do the 35 caliber version, but my 358 win savage barrel is not beefy enough on the chamber end to be rechambered in the fat cartridge.

SSGA,
Drop S&F a PM at AHN and show him the Kestrel ... I know he's umming and ahhing about what to do with his Featherweight 300WSM ... this might stir him up a bit. Mind you I dropped off a case for a wildcat 50cal on a 2.1" case that might drive him ga-ga. I think the short 50cal may be good for an honest 2150fps with a 535gr and is based on available brass from Bertram. Basically a short 500Jeffery with rebated rim at 416Rigby dimensions.

Done S&F has got an email......working on what basics i have got this round with sniper length barrel won't be far short of the 338LM bit only be 100fps in it :eek:

He has even load suggestions.

Try the 35X284. I have a .375X284 on a Mauser. The 284 has about the same case capacity as a 06.

Struggling with my German........Sorry unsure about his 9.3 bullet.

This Bullet has a BDC of .340 and the weight is about 185 Grains at 12 Gram and about 155Grain at 10Gram.
He is saying, that this bullet at high velocity has a greater impact and penetration then the equivalent of heavier standard bullets on game.
http://www.lima-wiederladetechnik.de/9,3-mm/Bilder/9,3-mm-KJG-spitz.jpg

This is for the 9.3X64 with the 10Gram (~155Grain)

Flugbahn (Fightpath) (He considers +- 2"(5cm) as the optimal for point blank)
Weite [m] 0 50 100 150 200 250 300 (Distance)
Schnelle [m/s] 1.056 1.003 951 902 855 809 785 (Speed)
Bahn [cm] -4,5 +1,2 +4,4 +4,9 +2,4 -3,5 -13,0 (Flightpath)

Leistungen (Penetration) 1" is 2.54cm)
Fleisch [cm] 66 65 63 62 60 58 56 (Meat)
Knochen [cm] 13 12 12 11 11 10 9 (Bone)

The velocity conversion from m/s to ft/s is 3.28 ie. 1056 m/s = 3464 ft/s. (Remember in Germany the .(Period) id the Thousand separator and the , (Comma) is the Decimal)
This really sounds fantastic, but he thinks, since only the drivebands are engraved by the rifling, therefor there is less friction and higher velocity!

The German Hunter likes an exit wound, so the can track game better!?

ME, I like a bulge in the skin on the other side, so that the bullet expends ALL its energy inside. But that's just me and my 2.01 Cents Canadian. :D

I hope this helps. If you need some translation, I'll try to help.

Wolf

Holy cow......that is a light bullet...

If the case i put it in gets it too 1150m/s then we are in for a surprise!

[Hi Guys, Pete Lincoln here. I'm a Custom Riflesmith in Germany. I'm currently playing with a couple of 9.3 wildcats.
The 9.3WSM is in the final build stages at the mo. just as soon as the postal service find the **** finnishing reamer that Dave Kiff sent on 10.10. I alread did a barrel by using a 300WSM and a 9.3 x62 reamer, it worked but the 2 different manufactured reamers gave a little step that i wasn't happy with.
The rifle will be based on a Howa 1500 for a start, before i migrate it to one of my own actions.
I would be interested in sharing any load data with anyone who has done it already.

next up (reamer is here) is a 9.3x.338LapMag

then a 9.3x308win

then 9.3x7.62x39 as a subsonic round.

anyone needing translation from German let me know.
ref the Lutz Möller bullets, some swear by them, some swear about them, nothing ventured nothing gained is what i figure,
all the best Pete

Pete,

Great when you do get it up an running could you PM me with some idea of the velocities?

SSGA

If you hear back from them, please post the data. Id be interested to see how the case pushes the larger bullets. I love my .325 WSM though.

The 9.3x62 or 9.3x74 would be better, but not in a SM. I don't beleive a 9.3 wsm could pass the 9.3x57. Jim

Geez! What kind of speculation is that. The WSM case holds about 15 grains more powder than the 9.3x57.

I have loaded and tested WSMs in 338, 358, 366, 375, 416 and 423. I have dies for all of these and have developed loads for all of them. Don't buy into the notion that if it would have been good Winchester would have done it. All of these are very useful calibers and the WSM case begins to dish out energy as the bore is opened to 338 and up. The 416 will lauinch 350 grains at 2400 fps, just on the heels of the 416 Taylor. The 366 shoots 250 grains at 2750 fps and is a good compackage with lots of thump.

That is the our 423 Dakota necked to 366. I did it in 375 and there is one still in use. The 9.3 on that case would be a good one, lots of space for powder.

Thanks Murphy very much appreciated! I have my 458Alpine (a 458wsm Blown Out) shooting 300gnrs comfortably at 2800fps in a 22" barrel 11yds from the muzzle, that is why the look at the 360kestrel on the same case.....:D
