I have already bought a Tradex Husqvarna M-96, in 9.3x62. I don't want to alter it.

But now I'm interested in a 9.3x64 Brenneke. Specifically, I'd like to buy another 9.3x62 or 9.3x57 and have it reamed out to chamber the Brenneke 9.3x64 cartridge.

Assuming you can safely ream out on of those 9.3x57 or 9.3x62 actions, to build a 9.3x64 Brenneke, with one of those Tradex Mausers, which specific action would you look for?

There is a confusing assortment of Swedish Mausers, German Mausers, Husqvarna M-96, M-98, Husqvarna 1600, in 9.3x57, 9.3x62 etc...
 
Personally I would only build a 9.3x64 on an M98 or FN98 action.

Also I've heard a lot of those 9.3x57's have short throats and pushing it from 57 to 64mm apparently causes bad erosion. I'm no gunsmith, but the throat is important to accuracy.

Also the Brenneke has a magnum boltface which requires the bolt to be opened up; not a big deal at all of course.

In the past couple days a lot of the 9.3x62's have been cleared out on tradeex, as well with the M98 9.3x57's. The Swedish Mausers are military M96's, German Mausers are military M98's and the Husqvarna are commerical small ring 98 Mausers
 
First, the pressure rating of the 9.3X64 is way over what you want use in a M/94/96/38 small ring action. Not that the action won't stand it, but it won't leave any room for safety if case head separation occurs.

Your best bet would be in getting a M/98 Large ring action, if availlable of the late FN manufacture.

But, it's wont be as simple as just rechambering the barrel; you will have to open up the bolt face and more than likely change the feeding ramp angle, and work up the magazine lips... not as easy as it looks like for a hobbyist "gunsmith".
This would have been way more easy if you started with a already magnum fitted action.. Then, it's almost a matter of only swapping barrels.
 
^ OK, so I start by looking at the M-98's. I had already come to that conclusion.

So how do I know if it's a large ring action?


Edit:
I looked up the cartridge diagrams. I see the problems... :(

I don't want to blow your bubble, but I hope you're a patient guy. For an "affordable" rifle, anyways, depending on your budget. While I am a real fan of the various 9.3, when I want more punch I go with a 375 H&H and now a .358 NM.
Maybe a bit less cool, but much cheaper to start with.

You have the big bore thing in a bad way. :D
The 64 is what I would own...Who makes brass?

What about a Montana action?
 
Seems you may get a Voere 2165 imported from Sporteque (Qc). They presently seem to have some stock in Europe.

RWS is pretty much the only source of brass that I could find. They also have factory loads for it. RWS is carried by quite a few retailers in Canada, but be prepared to pay a fair amount for the stuff.

Personally if it was me, I'd buy an 8x57mm FN98 from tradeex and then just re-barrel to the 9.3x64....or 9.3x66 Sako....or .376 Steyr. If you're looking for that "cool" factor.
 
I would definitely recommend a newer 98 action if you can find one, and I would go with a new barrel, since a lot of the older sporter barrels will be too small in the chamber area. The Brenneke is rated pretty high for pressure (like 64000 PSI on one website), so you definitely want to be on the safe side. I bought a prechambered and threaded Heym hammer-forged barrel from Bits of Pieces in BC, but I don't know if they still carry them (best barrel I've ever owned, by the way). I posted my Brenneke project in the Gunsmithing forum a while back, where I showed how I made my brass from .338 Win Mag. Basically I just used a small lathe to turn the belt off the brass, reduce the rim a bit (it's not a Magnum bolt face; about halfway between standard and magnum), then lube it up and full-length size it. I was surprised how close the case dimensions are to the .338. My rifle was an old 8mm mauser K98 that had seen better days finish and barrel-wise, so I did a full conversion.

I'm going to revive this old thread because I have a question on this subject.

I have a commercial FN98 and am looking to rebarrel it to a 9.3. It is currently chambered in 7mm RM. Would the current boltface function with a smaller case head like the 9.3x64 Brenneke, or even a 9.3x62? How much messing around would be required to make it feed with either of the cartriges? How much are we talking about for 9.3x64 brass and dies?

The bolt face will not work with the 9.3x62, and the brass will be very expensive for the 9.3x64, if you can find some.

On a side note, Epps is showing Zastava M98 Mausers chambered in .375 H&H for $780. I know it's not the 9.3x64, but the two are virtually identical in performance and you get the M98 action to boot.
