Any Positive comments? No changes to the .308 but a neck to 9.3. Keep your bullets to 250gr or less. Seems a bit large in bore size but in my experience the larger bore gets the advantage of a greater expansion ratio. I poo poo off any person that says the 358 winchester is just a mid range round. If so, then so is the .308. But we all know better than that! A lot of terrorists know better first hand. I actually don't care if it is a midrange only affair. Here in Misery my longest shot on whitetail has been about 125 yards and more often than not 50 or less. One was 10 yards but he had a broken front leg. A pass through on the doe got him.

Modern day 9.3x57, I'd prefer the 375/08 as you have better choices in lighter projectiles, plus the option of a 270gr RN.

Use 358 win brass and change te 5 into a 6. 368 Win
I would just rather use a 358 Win.
Perhaps use Shortened 9,3x62 dies and reamer to length.

It's one of those "WHY" cartridges. It would be a good one, ever bit as good as the 358 or the 375-08...slightly larger than the 35 cal, slightly smaller than the 375...just a "tweener" and heavier bullets are available for the 9.3.

Basically a "one off"...bragging rights maybe, lots of negativism probably...great for a mauser action but so would lots of other slightly larger cases...9.3 x 57, 62, 64, 375 Ruger and all the -06 case, WSM cased calibers.

Hard to justify except for "Justdoingitforkicks".

Someone probably has done it already somewhere.

Agree with 'Justdoingitforkicks' category.

For the short action aficionado the .375-08 chamber would make more sense. Just run .375 Whelen headstamp brass into the FLR die and trim to proper length; engrave the barrel '.375 Whelen - Improved Short'. Good to go.

Likely falls into the 'Justdoingitforkicks' category as well...

A 9.3-06 might be interesting, somewhat like a 375 Whelen. The 9.3 is attracting quite a bit of interest in my hunting/shooting circles. Sisk did one on both a 350 Rem Mag (9.3 BS) and an 8mm Rem Mag (9.3 Sisk Magnum).

9.3 '06? In that case just get a 9.3x62.
9.3 '08? certainly doable but you will need custom dies, and reamer, which are expensive. No good reason for either.
Go with either 9.3x57 or 62.

Just think, you could out run your bullets!

I would opine that there are several similar cartridges out there. 9,3 by: 56 or 57mm that would be much more cost effective. Of course, I am one to talk, building a 550 caliber cartridge on the 505 Gibbs.

9,3*54r sako (rebored mosin-nagant)

or wildcat 9,3-8*57irs for express rifle.

I don't think its a do-able cartridge, just not enough powder capacity IMO..I would however suggest that if one had to have short action, or a lever gun, then the only feasable wildcat would be the 9.3x284 Win.

That article from Sisk/Barsness is what got me going on the 9.3x62. I have a drilling in 9.3x72R and the 9.3BS looked pretty cool. In the end I stuck with the 9.3x62, and the 358 Win.

I think a 9.3-08 is a great idea, but the 358 Win covers it. On the other hand, the 35 Whelen is a great cartridge, but the 9.3x62 beats is what the Whelen should have been. I wanted 35 Whelen for many years, but the 9.3x62 beat it in every way.

While I shoot the 358 Win with 250 grainers, it is better with 225. I wouldn't even call it a mid range caliber. Short range; perfect woods cartridge for whitetail, or close in black bear.

I would do a 9.3x57 or better yet a 9.3x62 and be done with it..Wildcats are fine, but duplication of a factory cartridge is questionable and only for those who need to get a real job!

What action did you have in mind if you were to build one? It'd be expensive, but it would be fun to have an ultralight 9.3-08.

Your limited on an action, probably just use a 98 Mauser with a short box, short bolt stop. but that would accept a 9.3x62 without modification ?? Seems like a 9.3-08 is chasing your tail, it has no upside that I can see.

I suppose you could use a Rem 722, a Ruger 77 308, etc. Maybe a Ruger Int. manlicher, but you will still have duplicated a 358 Win.

Doable? Lots of people love their .358 Wins, wich gives 2400 fps With a 250 grs bullet. A 250 bullet from a 9,3-08 will go faster, and a 250 375-08 will go faster still.

One of these was recently put together in Australia where we have access to a monolithic 'soft' of 190gr weight. Owner is still playing with that projectile plus the 232gr Norma. Nothing wrong with both it, and the slightly larger again 375/08.

+1 Wildcats are fun, but this is certainly not one that I would waste my time or resources on. A slug as substantial as a 9.3 deserves at least 57mm of capacity, preferably more. Better to just buy a 358 Win or 9X57 and spend your wildcat $$ on something else.

That would make it a 9.3x51mm

How much difference are the paper numbers comparing this chambering to a .375winchester?

in my mind it doesn't seem much at all?

There is nothing wrong with using the 308 case from as small to as large as you can get...and there is ALWAYS a nitpicky bit when comparing different cartridges...something bigger and something smaller...the something "better" is in someone's mind more than in actual use.

ANY of the midsize case/calibers will do a good job on the game most people shoot...antelope/deer/black bear/elk etc. Very few get to go to Africa and very few get to go after moose
and if you would like a neat, bragging rifle the 9.3x308 will fill the bill nicely, but be prepared for the usual BS, not everyone has the sophistication to understand all the nuances in the wildcat/"Igottabedifferent" milieu.

I still think a 9.3 WSM would be pretty slick.
Hope to build one someday.
But my g-smith went to work for Blazer.

That's a very good one as is using the 284 case...each basically adding maybe 10-20 gr H2O over the smaller cases, in steps. Basically you gain the heavier bullets as you go up in caliber and more velocity as you go up in volume.

The Rigby case has also been used, shortened a bit and the Gibbs case shortened to work through a short action would get you even more pizzazz.

Hey...it's all good...each working to a particular niche for those that like to experiment or just mess around.

Or you could caliber up a 8,5reb to 9,3
and have the same performance as 9,3-284.

Actually I have wanted to get a 375-284 for years. But I wanted it in a Savage 99. Haven't found a 99 in 284 I could afford. I was thinking a clip model if they made it. But I can find affordable 99s in .308.

I think it would be a hog basher of fantastic levels.

It would be wonderful in a AR10.

My 458 SOCOM would be a basher of pigs too, if I get to hunt them.

the only good reason for any wildcat with the plethora of calibers on cases these days is because you want one to tinker with...

I understand these are common in your neck of the woods. Wonder if anyone has ever done this converstion on an SVD/Dragunov. Now THAT would be interesting!

I have 2 358s, a 9.3x57, 2 x 62s, but a 600 Remmy that needs a barrel. 9.3-08 or 9.3x51 still sounds good to me in spite of the naysayers.

I have a reamer for a 338 x 308AI.

Still thinking about this project and now have a different base to work from, a 673 in 350 Rem Mag. Thanks for all the naysayers. I helped to identify you guys. Like steelhead on the 'fire you are duly recognized. And Ray, I always value your thoughts. You have helped steer me in certain directions over the years. And I can't bring myself to rebore that Ruger tanger F/S to this project or just to 358 Winchester...….. Yet. I think the 375-284 is still in my mind and still cruising for the 99C to build it from. Packy

Pakrat,,
I built a 338/284 on a 99 Savage and it would balistically clone a 338-06 except for the fact that you just cannot push a 99 action to bolt action pressures no matter what anyone says..

The cases tend to stretch and come apart after about three loadings,due to rear lock up, so keep a 45 cal. wire brush handy to get the other half of the case out of the chamber, that's what I did..I figured out it was good to about 3 grs. short of the 338-06 for a max load and around a 100 to 150 FPS slower..It just didn't work out for me..Also you have to tinker and RECUT the rotary spindle and only Dennis Olson seems to have that figured out..so I got a 1909 and built a 9.3x62 always a good option. I think you would have the same problems, but a clip model would make the conversion much easier and less expensive. Ive often wondered if a Browning BLR might not be a better option??

bent fossel,
Do-able is in the mind of the beholder, in my mind it is not a do able caliber, didn't mean it wasn;t an option, In my respect I would just buy a 358 win..sorry if I misguided my post to include all...
