Does anyone have any experience, or know someone who has any with this? I've got a standard commercial mauser action that needs to be built, it's really becoming a problem just sitting there! I've been searching around, and from what I can find it seems the 404 was actually designed for the standard action, but you have to remove metal to get it to fit/feed correctly, and you need 375 H&H length bottom metal. Any pros or cons with doing this? Thanx for all the help guys!!

You are right in all cases..

a standard action can be cut to make it work, and if you are wise, you'll pull the most you can from the back, not front, of the action.

a m70 in a 300RUM is the perfect doner.

jeffeosso,
If one has a m70/300rum to start with, other than changing barrel, what else needs to be done? What if you start with a rem 300rum? Thanks

Barrel, some on the feedramp, and done ...
if you start with a m700, forgetting that its a push feed, it would be a VERY slick feeding rifle. A bit odd, but no more so than a 416 rem on a rem...

seriously, it's a rebarrel

He has the correct geometry for both the magazine and the feed rails programmed in his CNC. With expertise like that, it's a cinch and guaranteed to feed based on the correct geometry.

I owned a very sweet H&H built on a post war F.N. commercial action (no cut out for stripper clip feed). A fantastic carry rifle (under 8lbs loaded) but...for a PH's point of view ...NB this applies only to a PH, for you as a client it isn't important -
1) To reload the magazine you had to "hook" the rounds in under the rear reciever bridge.
2) Ejecting a live round wasnt always easy. There was a little cut out in the front reciever ring where the nose of the bullet was ment to flip out through. Didn't always happen.

Compared to the cogwsel & Harrison I owned built on a P17 action the H&H was much slower to reload, and if you needed to change from soft to solid (or visa versa) in the chamber, could be done "eyes off" For both operations you needed to look what you were doing with the H&H!

Still the lad that paid me a kings ransom for the H&H is Very Happy with it. It goes Bang every time he pulls the trigger and there are no issues of the safety poping on during a relaod - which is what got him run over by a buff when he was using a CZ .458 Lott!

A different Idea I like alot is to build the rifle up as a single collum feed. There are at least two companies in Begium that make magazines, floor plate etc for such a conversion. Damoulin outsource their components and I have magazines form two different makers!

Need to work the bottom of the front reciever to make it accept single collum feed and install new floor plate and magazine- done. Still will not eject live rounds without a fiddle though

How many frigging times do I have to explain about the CZ safety modification on the CZ so that the bolt throws the safety off when the bolt closes:

Stuart Satterlee? I'll run by his site and see what he has to say. Thanks new_guy!!

Totally agree, I love mine. It's easily the best bang for your buck in a semi custom or full custom 404j. I even used the existing wood stock w/ a few mods. It's very accurate & 100% reliable w/ everything but those pesky FP solids from NF.

I'll post a pic when I get home but with the new bbl. installed it fed fine w/ the RUM follower. I shortened the existing wood stock, added 2 steel cross bolts, Dakota 1/4 rib & NECG banded front. It's a great shooter. I call it mu 42cal varmint gun.

I have had a number of .404 on FN actions and 98 Mauser actions and M-70 actions..Dennis Olson did the metal work, I did the wood..

Dennis opens the magazine up in the rear and probly removes less than a hundred thousands from the ramp and thats zilch..A little rail work and presto they all worked like a charm.

I would not waste a big action on less than a 505 Gibbs or that ilk...

I can't think of a better caliber than the 404 Jeffery's, but from a practical standpoint the .416 Rem is about tops.

If using a Rem or Win Mod70 action in 300 Rum wouldn't you have to open up the bolt face for the 404 Jeffery, not just a rebarrel?

I have .404 built on a 1935 Brailian Oberndorf standard size action (metal work finished, waiting for the stock work) by Jack Haugh in Indiana that feeds perfectly. He made the quarter rib, barrel band front swivel, & barrel band front sight ...... the rifle looks like a new "old" English rifle, and like I said, it feeds four down perfectly (Blackburn bottom metal). When finished, it'll be a real classic.

Here is mine done on a M70 RUM:

That is a very good looking rifle. Jeff

mr rigby on this forum has a .404 built on a VZ24 action.

For what it's worth, SABI Rifles of RSA makes 500 Jeffreys on standard M98 actions. His method of modifying the magazine well is to take 1 1/2 MM (.060") from the front and 3 1/2 MM ((.140") from the rear. I believe that would work and not weaken the lower locking lug recess for the .404J as well.

Okay, so a rebarrel job on a .300 RUM and some work on the feed rails and that's it? That sounds a little to good to be true! Is it really that easy?

Thanks Jeff, I am happy w/ it.
Mikey, that is pretty much all I did was have my gunsmith drop a new bbl. in & the feed rails needed a bit of tweeking & away you go. As you can see, I even used the RUM stock w/ a few mods. A CZ will be the cheapest way to go for sure, but the M70 RUM makes a nice rifle for a semicustom price.

fredj338, that is a great looking rig. I've been considering doing the same thing for my first big bore.

Could this be done on a Sako 75 300rum?

Thanks. I don't see why not a Sako RUM, but it won't be a CRF?
