If I were to build a 9.3mm WSM, would I be able to make it fit into a short action and still have adaquate powder capacity? What kind of performance could I expect from such a caliber? 9.3x64 type performance?
I suspect you would limit yourself to very light bullets, why not the 338 case if you want a wildcat 9.3...or just shoot a 9.3x62, lots of components out there readly available...
The 9.3x64 is a wonderfull round and I could sell you a lot of RWS cases, dies and even loaded ammo, at wholesale as I think I have mine sold..Just a thought.
I can't imagine where a 320 Gr. woodliegh would end up in the WSM case, probably on the primer
Adirondack Joe, I have a friend that did something similar only one a standard action. He took a 375 Dakota case and necked it down to 9.3. It has a 26 inch barrel and he uses RL19 and got 2950fps with a 270 speer bullet. I want to see how it shoots the 286 NP and woodleigh.

I've got a Lazzeroni Patriot (the slightly bigger brother to the WSM) that is necked up to 9.53 (.375) and I can easily get 2550 fps with a 300gr Nosler...I would expect you could get 2500 fps with the same bullet without straining anything and that isn't anything to woof at as most factory 300gr loads (except the Heavy Mags etc) do well to reach 2500 fps in a 24" barrel.

Ray, I have been waiting patiently for the past 5 months for my smith to complete my 9.3x64. I should have it in my hot little hands by the end of next week. What all do you have in terms of brass and bullets? Cobalt
My friend Brian Smith,who posts on HA,is making a 9.3 WSM as we speak.Make a post directed to him over there and he will be able to answer your questions.He also did a 35 on the Remington short case,but before Remington introduced it (he cut full length 300 Ultras down).

Jim Busha at Heavy Express has two lines of cartridges on modified .348 Winchester brass (rim turned off, taper removed and sharp shoulders). He doesn't show a 9.3 on his site, but you can get an idea of performance from the .358 and .375 cartridges he does have there.
Winchester knocked off his .300 in their .300 WSM design.
Joe, check out the 17th edition of Handloader's Digest. Norman Tonn has 2 9.3 wildcats. One is based on the .338 case and the other is based on the .348 Win. Very interesting article.
Curtis, That 348 case is blown out and the rim turned off, and is basically a 300 RUM case when finished...Not a lever round...
I strongly suspect a blown out 348 case necked down to 9.3 in a Win. M-71 would be a bit hot for that old action unless one loaded it with care. the 348 as is would be my choice, close enough for Gov. work.
Mr. Tonn used the .348 based 9.3 in a Siamese Mauser and kept pressures low in accordance with the capability of the action. But, I bet the Winchester '86(?), help me out lever guys!, would be strong enough as a buddy built an Ackley Improved .348 on his. Is that the right model, Ray? Has 2 locking bars that come up into the bolt?
The 348 Winchester was chamberd in the Model 71,with an updated 1886 action.Since they chamber them in everything from 30/348 up to 45/348 Ackley Improved (which outshoots todays 450 Marlin and rivals a 458 Winny),I'm sure a 348 necked up to 9.3 would work fine in the action.
