Has anyone here built a 350 WSM? I'm debating getting either a 350 rem mag or 350 WSM built, 22" light contour barrel likely on a Montana short action. Performance wize I'd be content with a 225 gr triple shock at 2700 fps, which looks like the upper end of the 350 rem mag, and easily achieved with the WSM.

Favoring the wsm would be that I'd plan to pare it with a 300 wsm, and brass will likely be available longer than for the 350 rem mag, though I could easily enough make 350 rm brass. I'm not sure who makes dies for the 350 wsm or what the added cost would be for them.

I figure the upside of the 350 rem mag is Montana offers barreled actions so chambered, and dies and brass are off the shelf. I'm not sure which round feeds better, probably a toss up. If I went with theg 350 wsm I'd likely have Pac-nor barrel the action.

Do you mean the 35 Sambar?, 250gn@2700fps.(max) Have a look in Cartridges of the World(wildcats)
Designed specifically for Sambar Deer in Australias Victorian mountains.
If I was to have one I would Run the 270gn Northfork @ about 2400. I would be a real hammer at those short/moderate ranges,without unnecessarily stressing the gun or pounding the hunter.

Paul H,
The 35WSM is the 35Sambar as put together here in Oz. Give me a buzz if you want me to email the load data presented when it was written up over here. Just note that no pressure testing has been done to the best of my knowledge, just loaded up the one rifle until visible pressure signs developed. So whether it achieves its velocities at 55k or 75k psi is still unknown.

Given the weight of projectile you have chosen why wouldn't you just go with a .325 WSM and be done with it ? Unless you really want 2 guns and consider .300 and .325 a bit close together .
Suggest you Google Shortmags.org forum . Heaps of info. on wildcats there .

Of the two you mention, I'd go with the 350 RM. But I'd really prefer a 9.3x62.

Paul, I'd be willing to loan you my .358X 404 IMP reamer.You can always load down.

I built mine on a 98 Mauser. It's a single shot as I didn't want to extend the magazine.You only need one shot anyway.right? roger

I have a goodly selection of 35 caliber bullet molds, and componet bullets, so have no desire to go with the 8mm. I also believe the 8mm can't produce the same velocity as the 35 with the same weight bullets, and I can step up to 250's or 270's if I go after bigger game.

The 300 wsm is more of a reach and touch gun, I plan to drive 150's 3300 fps, the 350 will be more of a medium range gun with 225's @ 2700-2800.

Thanks for the responses, I'll have to look up the data on the 35 sambar.

Roger, thanks for the offer to loan the reamer, but I'll likely just send an action to Pac-nor and have them fit and chamber, as they already list the 350 WSM under the chamberings they offer.

Paul,

I have the reloading data for the Jim Busha HE Mag cartridges (would be the .358 WSM with a 40 degree shoulder). Here is what he got with a 24" MR barrel:

200 grain -- 3,050 fps
225 grain -- 2,950 fps
250 grains - 2,860 fps

Data is the max for the bullet weight, taken at 15 ft from the muzzle, and at 6,000ft altitude (Co. Springs).

That was a great looking rifle that David Stendall put together, he seems to be a very good smith !!

If you are looking to make a lightweight short action rifle you probably can not go wrong with either.

I had a Remington 700 Classic with 22" barrel that was in the mid 2700s with 225 grain Nosler Petitions....and just plain hurt to shoot. Dropped back to 60 grains of WW748 at 2660 and get .75 MOA and plesant to shoot. Sold that rifle after buying a M600 carbine and just loving the balance and the way it carries.

As to the availability of brass...don't think it will be an issue in this life time. It would be nice if someone would come out with a well construccted 225 and 250 grain load however.

Paul, I'm not familiar with the 350WSM but I like the 350 RM, I have one in a SS Ruger m77, killed a moose with it this year I'm now working on a better load (the 225 Noslers) One of the things I've found about the 350 is that it is a short bullet and having the neck of the brass get a good hold on the bullet is a little tricky. I am sending a round to Lee to get a crimp die. But that is something to keep in mind. I don't have a lot of experience with it but that's something you are going to have to deal with. They sound pretty close, and I agree I don't think there is going to be a brass problem with the 350 RM any time soon.

Hey Paul, My 350RemMag is on a M7KS with the 20" barrel and it is TOO short. You absolutely can not hunt with it unless you wear some sort of ear plugs. The 22" would be an improvement.

Have you taken a 300WSM and opened it to 35cal and then compared the Water Volume of it with a 350RemMag?

And what is the length of the magazine in that Montana Short Action?

I'm limited to 2.8" in the M7 which is fine for the bullets I use. But I can see where it would be nice to have a bit more room for the 225gr and heavier bullets.

Best of luck with the project rifle.

Bear Paw Jack....I and my friend who shoots a M673 just bought Lee Factory Crim Dies. I have not had a chance to load with it yet but did run into another M673 shooter who had loaded some 225 Noslers and they were shooting fine.

..as to how much muzzle blast....I am deaf so it doesn't matter.

Bob

Hot core,

I actually did neck up a 300 wsm case this weekend (looks good ), though I didn't check for powder capacity. I believe the montana short action allows a COL of 3.1", but I'm not positive on that point. Whether 2.8 or 3.1, the 350 wsm definately has the powder capacity for 225 gr @ 2700.

First things first, I plan to get a Kimber montana in 300 wsm, and if I like it, then I'll build a clone in 350 wsm.

I'm thinking the 22" is a good minimum to keep muzzleblast down. As much as I like to put earplugs in when shooting, when going through thick stuff with bears present, I just can't abide hearing protection, even the electronic muffs. One of my hunting partners had the electronic muffs, and it seemed he'd always be looking away from me when I'd try and get his attention.

Hey Paul, Everyone seems to speak real well about the new Kimbers. If I liked that M70 style, I'd probably get one to try out too.

I wear the Sonic Ear Valves when I carry the 350RemMag, but I certainly understand why you want to be able to hear everything thats going on around you where you are hunting.

I've shot 308Wins and 358Wins with 20"-24" barrel lengths over the years and never had a problem hunting with them. Just amazing to me that adding a few more grains of powder to what is used in the 358Win makes such a noise difference.

Anyway, I wish you all the best of luck with the two rifles. Sounds like a fine plan to me.
