338 to 404 Jeff Login/Join

Is it possible to convert a Win Classic 338 mag to 404 Jeffery? I've heard you can convert a 30 06, so the 338 should be ok? I really don't need the 338 since I've picked up a 300 H&H for my plains game rifle. Thanks for your help. James

Be a lot easier to build a 416 Taylor.

But a 404 and a 300 H&H would be classic...a 416 Taylor? Pffft.


Cool

.. If I wanted to push a .423" bullet I would make a 425 Express ...It will kill anything as well as anything else will , and you will always have brass ....


.If it can,t be grown , its gotta be mined ....

416 Ruger makes more sense now that it's been officialized and factory brass will be available.

And neither are classic anything. I would rather go thru the trouble and build the 404 Jeff.

A 404 is always your best bet IMO..It is truly a classic, I wouldn't be without one. But then I am a total nostalgic I suppose.

James,

Another vote for Dennis Olson. He did some feeding work on my .404 based on a ZKK 602 action. Excellent fellow to work with.

Ray or David, How do I get in touch with Mr. Olson? If I am able to get the conversion it will only be a 404 Jeff. I'm totally into the classics that's why I got the custom 300 H&H built on a Mod 70 pre-war action.

Reading Kuhnhausen's mauser book, I'm led to believe that converting a standard length mauser to a cartridge like the 375HH or a 404 Jeff. dangerously weakens the action. Is that what you were talking about with the conversions that Mr. Olsen does?
At the moment, I'm hoping to put a 9.3x62 barrel on my VZ24, but I'm looking forward to a 375 H&H in the future.
Thanks!


Dave

It certainly can if all the metal removed to make room is taken from the front of the reciver and magazine box. If done correctly, about .120" is taken from the rear of the magazine well and .060" is removed from the front of the well and great care is taken to NOT cut the feed ramp at too shallow an angle. Zastava and many reliable custom firms have been doing this for a century or more and I haven't heard of their guns blowing up or even less catastrophic failures. I would believe that if Dennis Olson does the job, it will be done right.

Tip Burns, Canyon Lake, Texas built 2 404 Jefferys for me on Montana Rifle Co. Long actions. John Valicek of Canyon Lake did the stock work. Roger Kehr did the engraving.

MasterRifleman,

Thanks for the info! I had been reading an article in Sports Afield about the 404 and it mentioned that "thousands of Mauser 98 rifles chambered in .404 Jeffery were delivered to colonial officers, rangers..."

As seemingly rare as magnum length M98 actions are, I wondered if these were converted standard length M98s.

Great website, by the way! I only found it recently. Thanks for the info.

The guns sent to Africa that were placed in the Game Depts inventory were not M-98 Mausers, but in fact were FNs in 404 Jefferys and many of them are still in use in Tanzania and perhaps in Zimbabwes Game Dept Arsenals..

I have a beautiful FN 404 about 10 years ago and let it get away from me. It fed 110% and was very accurate..but it had an old muzzle brake on it from yesteryear and that bothered me so I peddled it for a good price..wish now I had kept it...
