I know this has to hvae been done before, but I'm not finding any info online, maybe you guys can help.

Take a 375 type case (Wby, 416 rem, H&H) with the Rem/Wby minimal taper and sharp shoulders, neck up to .423 and be sitting between 450/400 and modern 404J ballistics. Anyone know what this would be called? Not the 425 Expres, thats on the 2.5" case. I've got a lot of 300 Wby brass and I think I might be done with the 300 so I have a rifle and brass, but don't want all the expense of making a true 404 Jef

I like to have a belt or a shoulder but I dont like both but that is me. I would like to see a 404-374 H+H but no "Improving" what you will have is a belted tapered case without a shoulder. slick feeding!!! rebore a 375 and use a neck throat 423 reamer. fireform or just neck up formed brass. Call it the 423-375



If you lose your ammo just buy some 375 and swap bullets using an expander and your ingenuity. this wildcat has a little performance increase with the larger bullet but the ease and cost of conversion and ease of forming cases to be found in Africa is the beauty.

use a 458 winmag case, and its called a 425 african express ... by savage....

using full length cases would cause one to spend about 1K just for the action...

He already has the longer action.

Reboring a 375 to 404 is the way imho.

I would sell or trade the 300 for a 375.

keep the sights ect and feeding should not be an issue on an unimproved case.

I already HAVE the 3.6" action, so thats not a problem. Now if I wanted to build a normal 404 J, then yes, I'd be looking for a CRF M70 and spending over 1000$

However, I'm no purist by any means, so my push feed M70 will do just fine.

So the 425 Express...just longer lol thats what I'm looking for. I didn't even stop to think that if I had the belt, I'd need no shoulder *doh* so thanks for pointing that out BS. I also like the pull-and-shove idea in the worst case scenario of lost ammo.

So no info on this? I mean seriously...this has to have been done lol these 2 cartridges are SUPER old, and it seems every case has been necked up and down in every conceivable caliber

Selling/trading the 300 wouldn't really get me very far. I don't run into many 3.6" rifles used around here as it is, and the stock has some scratches, which is why I got it so cheap. I'd probably only get 150$ trade or sale from a LGS on it. Cheapest route is just to rebarrel

also makes a great case for the 375 Taylor, as I'm sure 338 Win Mag ammo can be had around the world, pull the bullet and stuff a 375 in there!

Being that the shoulder and neck juncture of the 375 is so shallow it would be easier to get the neck to feed simply expanded formed brass.

I would use an expander die and a hammer or rock if need be. Big Grin

Think of this as a 458 lott but a lot more taper and lower recoil.

NICE!

I just got a few emails from my gunsmith about doin a switch barrel on this rifle. I think having a 300 and 404 barrel (maybe a 375 Wby stuck in there too) solves a lot of problems! That covers everything I could ever want to shoot at in 1 gun. Of course if something happens to that gun, well its rental time lol

Bent -

I see lots of 411 and 404 wildcats on places like Qual Cart, but they don't tell you what they are, just the name. I KNOW someone had to have done a 375/404 before, but I can't find any info about it. If it IS the 424 OKH then thats even better, because Qual Cart has brass. If you find out anything please let me know!

Why not neck 458 Lott brass to 423?

Now that Hornady is loading the 404 Jeffery, the original is the poorest way to go anyway...
Nr. 2 is the .425 Express.
Any other is not poor at all...

I got another confirmation that the 424 okh had a shoulder so it was an improved case. So this is new that I know of so far.

Yes forming Lott brass will be easy. The idea of using modified factory 375 ammo in a pinch was a neet idea.

The original 404 is still not the cheapest way, Bent. Brass costs more, I wouldnt use factory anyways as I reload, and the modifications needed to the action raise the price of the rifle conversion. And really all this is, is an extended 425 Express more or less.

Using 458 Lott brass would be the same as using 375 H&H brass lol neck one up, or one down. Heck I could even use 8mm Rem Mag, 416 rem Mag or really just about any full length 2.85" case. I already have 100 pc of 300 Wby brass, so this is probably what I would use. Might be a little tough working the brass out straight, but at the same time once its in season Midway sells 1x fired 375 H&H brass for 10$ per 20

MileHighShooter.

Multiple confirmations that the 424 was an improved case with a shoulder.

This seems to be an undone wildcat so far.

Pete from Quality Cart said we could do the unimproved version headstamped at the same cost as the 424.

Only question is what to name it bewildered

404 Safari?
423-375?
404 H&H?
10.75x73?

Let's just call it a 404-375 for now.

As you can see the neck of the 404 is 2 thou larger than the 375 shoulder. so the necking up will take out the shoulder.

The Neck ares that will give the bullet tension is .45" or just over a cal length neck.

so taper to 2.4" and 2.85" length.

I think 300 @ 2500, 350@ 2400, 400@ 2300 and 450's @ 2,200 would be a good goal for this case.

So in the spirit of "poor mans 404"

Cheap brass and a rebore or rebarrel away. Minimal mods.

Go figure, after so many ideas, the one new idea is combining 2 ancient cartridges together lol. I'm in love with it, the ease of building, loading, brass, getting stuck without ammo and just fitting some 423 bullets in a 375 case. And I think you're right on with those ballistics, old 404 numbers should be a breeze.

Now, as far as the chamber itself...how do you propose I go about that? New reamer, or just rebore a 375 H&H and see if that "creates" the chamber we're looking for?

Glad you like it!

Well if you had an existing 375 maybe you could get by with opening up some 375 dies and a neck/throat reamer but a rough and finish reamer is best and to have custom dies made. Also got to make sure the 375 barrel profile is thick enough for the rebore.

If you start from scratch with a new barrel you could do a combo of using the 375 reamer with a floating pilot and the 423 neck throat reamer.

There are a few ways to cut corners but a whole new set of reamers and dies is best.

Yes, I think this Idea is long overdue. with the advent of the rise from near death of the 423 bullet thanks to hornady and North Fork this is a beauty.

It's beauty comes from its simplicity and practicality... or the best you can get when wildcatting.

The 404-375 name is important. First off if you know cart nomenclature it will tell you what it is from the name and if you made a 404 stamp you could headstamp your own brass using 375 cases.

Add this to the other few but fine belted no shoulder rifle cases.

So 404-375 H&H it is! I am curious about doing my own stamping though...I'll have to look into that more. That would be great, seeing as H&H brass is about as cheap as it gets!

And don't forget Barnes and Woodleigh in the .423 arena Wink More then likely, I'd play with Hornady and Barnes first, just for the simple fact they're cheaper bullets.

Powder should be an easy one too, I've got plenty of 4064 and 4350, I see those in 375 recipes frequently.

Glad to hear clap

Well I assume you will be doing the switch barrel on you WBY action right? If so a new barrel of at least a 1 in 12 twist to keep the 450 woodleighs stable imho. Well first things first... For the sake of lead time an order of the reamers are a priority. Dimensions would be easy since they are of all known factors. A dummy round or two would be good to play with and measure dimensions of necked up 375 brass. If headstamped brass was wanted that is a 4 month lead time. Headstamp brass is nice but only needed to travel but it is cool.

So a list that comes to mind.

Dummy rounds
Reamer order
Dies order
Barrel order
Trip to the smith
Form brass
load
BOOM! BOOM

Making wildcat history is fun banana

Oh yeah... what barrel length would you use?

Well I guess I'll have to get me some H&H brass..although I have a few pieces of 300 H&H, I don't think the simple up sizing will come out the same. And then some .423 bullets. Good thing the gun show is next weekend!

Barrel and smith stuff is already taken care of, I have a pal who is a 'smith for a very famous and widely used shooting sports supply business. In fact, in a few months when you're watching the weekend shooting shows and you see little segments from Larry Potterfield about the ongoing 300 Wby project...guess who is building that gun Wink

Well, if you wanna go cheep...
The new cat is in the prosess, and I like it, but it is not a poor mans .404.
Poor mans .404 would be to buy a factory CZ and use Rum brass. Not 100 % reliable, but close.
This cat is of course cheep when the chamber is made and dies are bought, but...

But hey, good luck, mate!!

As I put on the other thread there is a diferential on the custom stuff but the cheap brass, reloading and cheaper smithing bill will help make that up.

I hold the 425 Express in very high esteem! Fact of the matter is though, I have a 3.6" action to work with, so I wanted a full length cartrdige without modding the action to feed the larger 404 Jeff.

I like the cartridge idea and I think it would have been a better cartridge for H&H than their .400 H&H with its .411 caliber bullet. Also, had H&H produced this round I believe they’d have used the UK norm of identifying the parent case first followed by the caliber – the inverse of the USA norm that you’ve used - in naming this cartridge. I also doubt that H&H would have given Jeffery, their competition, any credit in this cartridge by using the .404 designation in its nomenclature.

So I perceive that they’d have named the cartridge one, or all, of the following:
.375/.423 H&H Magnum, or
.423 H&H Magnum, or
.423 Belted Rimless Nitro Express (.423 BRNE)

Cartridge was conceived by Cameron Hopkins, and designed by Whit Collins. It is a 300 Win Mag case, necked up to accept .423 caliber bullets. Savage, to my knowledge was the only gunmaker to ever offer it as a production rifle in that chambering.
