Here it is, using the 2004 posting of specs by Saeed's own measurements of his brass:

I could have done this 8 years ago, but had to get some wildcatting out of my system.

No doubt the .375/404 Jeffery is the ultimate hunting rifle cartridge for many reasons.
Saeed's cartridge measurements from 2004 are good enough.

I am going to use those as brass maximums.
and will design a reamer to fit that.

Here is the cartridge drawing, using the RCBS.Load tool, Cartridge Designer:



Here is that one piece of brass Saeed gave to me in Tanzania, 2010, loaded with a Barnes TSX .375/300-grain bullet to exactly 3.750" COL:



And here is the Norma 404 Jeffery brass loaded with a Sierra .375/300-grain GameKing bullet for fireforming:



I am all set.
No need for anyone to bother with anything else for me.
Thanks to Saeed for the design.

I have confirmed brass neck diameter of loaded ammo as 0.405", using Norma 404 Jeffery brass.

The reamer neck diameter will be an accurate 0.408" diameter, same as Saeed's reamer, the only actual spec known on that reamer.

The throat however will be identical to that of the 2001 CIP spec for the .375 WBY.
The smallest 3-shot/100-yard group of my life was shot with that throat and a John Bridger copy of the Walterhog .375/300-grainer.
That will do.



I plan to have Rusty McGee of Falls of Rough, Kentucky build two rifles for me in .375/404 Jeffery Saeed.
No. 1: CZ 550 Magnum with 3.8" magazine box length and 26" barrel
No. 2: Mauser 98 with 3.6" magazine box length and 23" barrel

BTT just to get above the closed poll.

A chicken in every pot, a .375/404 Jeffery Saeed in every Rifleman's hands ...

Who is this Jeffery Saeed fellow?

Yes, that was a good one.
So is this cartridge.
So is that Saeed fellow.

All the best with the efforts.One day when I can have the rifle built, I shall ask your suggestions.

Best-
Locksley,R.

RIP,

Saeed's 375/404 is by all accounts a great calibre and it is his creation. It belongs to him.

I have been carrying a 404J in the field the last few years and I would be hard pushed to improve the capacity of 400 grains. It is considered a classic and puts down big game well. I was recently given a .500 which is a very big hitter. I am sure this will replace the 404J as a carry gun. Saeed's 375/404 would make for a great medium bore and both the mentioned calibers are greats and have proved themselves time and time again in the field. My observations would be that the .375 H&H is the better with select ammunition. Other greats like the 9.3 by 62 and 64 have to be considered and the the .338 something or other. Commercially I think we are pretty much covered on mid range calibers.

RIP: That is simply awesome accuracy. What was your velocity? GOOD FOR YOU!

Surely it does. Just as surely, Saeed does not mind some imitation of his cartridge.

So I have been carrying a 404 Jeffery in the field longer than you? I started that 9 years ago. Bison was the first game to fall to mine.

... and I would be hard pushed to improve the capacity of 400 grains. It is considered a classic and puts down big game well.

So what else is not new?

I was recently given a .500 which is a very big hitter. I am sure this will replace the 404J as a carry gun.

I was shooting sub MOA 3-shot/100-yard groups with Mitch Carter's 577 T.Rex in 2001.

I was getting on paper at 942-yards with a 500 A-square and Hornady 750-grain A-Max bullets at 2150 fps MV, before the turn of the millenium.

The 500 Mbogo is my Wildcat and it went to Tanzania in 2010.

I am not impressed by a 500 Nitro Express.

Yes, I cut my teeth on a .375 H&H , it will do. But I am a gunnut and a RIFLEMAN from Kentucky, where we have a long and proud tradition,
of the Kentucky Rifle, even if it was made in Pennsylvania.
I would rather be a man of 200 rifles than only 100.

Other greats like the 9.3 by 62 and 64 have to be considered and the the .338 something or other.

The 9.3 mm put me to sleep, but I keep a couple in the safe.
.338s I have galore, from .338-06 Mauser Modelo Argentino, to .338 Lapua Longbow.
I slept with a .340 Wby all over Alaska starting in 1985.

Commercially I think we are pretty much covered on mid range calibers.

But none is so perfect as the .375/404 Jeffery Saeed.
This is my considered opinion after 49 years of shooting, since a 12 guage Ted Williams shotgun sent my little eight year-old butt tumbling.
In 1972 at West Point, at age 17 y.o., I scored 299 out of 300 on the rifle qualification.
I think they locked that last 300-meter silhouette to prevent a plebe from getting a perfect score, as part of the hazing.

I have wildcatted from .375 to .510 caliber, heavy on the .395 caliber, from .375/.338 Lapua Magnum (before I new it had been done before me) to .510/.416 Rigby 3" (500 Mbogo).

Thus, I have duplicated someone else's .375 wildcat before, member 2RECON's 9.5 x 70mm "Tornado" Magnum.
I now have German-made dies from Treibel, thanks to 2RECON.
See? No hard feeling.
He might even feel flattered by the imitation.

Do you really think you ought to criticize the bringing of the .375/404 Jeffery Saeed to us masses?
Call me "Prometheus."
And if you ever need some education on rifles and cartridges, I shall happily oblige to the best of my ability.

Let's get a rifle maker to chamber it and a ammo maker to provide the ammo. Call it the 375/404 Saeed. I'd be up for one!

Bill,
That was a 2717 fps load, but a little warm for that long-nosed Walterhog-Imitation 300-grain bullet in the .375 Wby with 78 grains of RL-15.

That load might work better in the .375/404 Jeffery Saeed, even though H4350 is the best choice for both cartridges with 300-grainers.

Robin,

"We'll keep the light on for you."

Use Enough Gun needs to "Use Enough Search Function" and catch up on the last week.

Use Enough Gun was in Mexico part of last week and had Not Enough Internet connection. Rip my friend, please cut me just a little slack! Sorry I didn't do some retro research! I'll learn next time!

UEG,
You are good. Very good if you got in and out of Mexico.

Rusty McGee is going to build two for me, at his Falls of Rough, Kentucky shop.

Reamer first by a guy named Dave,
then fire formed brass,
then dies by Hornady Custom Dies, mass production!

Saeed gets by using plain ol' Norma "404 JEFFERY" brass for the "375/404 JEFFERY."
A Barrel stamping of "375/404 JEFFERY SAEED" should work just as well.

If you want one, send your parts to Rusty McGee.
Parts is parts.

Canuck,
Update here:

Saeed may have had Redding and other reloading dies too.

I'll have Hornady Custom Dies.
Maybe some Redding dies too.



Reamer in the works.
Based on Saeed's brass measurements from 2004.
It will be perfect.

Again here is the brass spec.



I am combining a Dave Manson 404 Jeffery reamer base spec with a Dave Manson .375 Weatherby throat spec.

I have had excellent results from those reamers, in all regards to 404 Jeffery Norma brass compatibility and .375 Wby accuracy with Walterhog bullets.

The neck and shoulder and headspace specs come from Saeed's measurements,
as well as measurements of my Norma brass dummies, and one of Saeed's pieces of brass,
and my vast experience with designing wildcat reamers made in the past.
I just now finished a drawing of the reamer body using the RCBS Cartridge Designer tool,
with the rim and extractor groove zeroed out.

Will hand-draw the throat, and hand-draw the full Manson reamer print.

Then run it by Dave Manson for his opinion.

The reamer base diameter is 0.546": standard for Dave Manson and CIP, 404 Jeffery.

The length of chamber is 2.835" to allow the usual 0.015" extra for case stretching.
Those are the easiest two measurements to establish.

Neck-2 chamber diameter is 0.408" at case mouth.
Neck-1 chamber diameter is 0.409" at shoulder juncture.

Shoulder angle of the reamer is 26-degrees-10'.

Free bore is a tight 0.3756" diameter for the .3750" bullet diameter.
Freebore length is a parallel-sided 0.3700" long.
Leade angle of throat is 1-degree-7'.

Ought to be perfect.
Stay tuned to this thread if interested,
the other is dead.

I'll post reamer updates here: SEE BELOW

I hope everyone gets the magic that obviously goes with this miraculous cartridge. Now if I could just get originator's money to go with it I might consider it. I can't match the author of this thread's prowess and great experience with all these magical cartridges but in 1956 at Ft Chaffee, Ark with an M1 I shot a 10 round 200yd course from standing to sitting with reload from the cartridge belt in the sitting position. The score was a possible and for those from Rio Linda that's 10 rounds in the VEE ring. It's really not that significant as i was only a draftee in Basic training. I also have a 375 H&H that shot a 20 shot (that's twenty) group from 100 yards from the bench. The group measured less than .750 for the 20 rounds. The twenty rounds were shot with no cooling or other interference from my Model 70 SS Classic in a David Miller laminate as fast as I could reload 3 rounds as that's what the magazine holds (The stock is slimmer than a regular model 70 as David Miller uses his own mag box which I didn't know till I had finished the stock so I cut the mag box to fit losing one round)so I don't have any idea I really NEED a super special 375. The only buffalo I have killed was with this gun with one shot and I doubt any of the magic rounds buffalo were any deader. Only animal I have ever lost with it was my first elephant from a misplaced brain frontal try. Now if by some magic you could produce large amounts of money I might be interested.

Missed this thread on my quick "scroll by" earlier.

Now I am up to date. Will not flog the dead thread any further and will stay tuned to this channel.

I was curious about Saeed's die mfgr just in case they may have kept a reamer drawing on file.

What do Hornady custom dies go for, and what's their usual turnaround? I am entering my 9th month of waiting for 450 Vincent Long dies from Dave at CH4D. I am very glad business is so busy for Dave, but my generation is not a fan of delayed gratification.

Thank you Sir! Interesting! And you got bragging rights there.

I get the drift that you too can appreciate that the cartridge, the rifle, and the sensual pleasures of the shooting itself
are ends in themselves.

And the older one gets, the more need for sensual pleasures coming from such sources, because of the unfaltering "professional small boy" spirit
trapped in a crumbling body. Seems to be the "case" for me.
Everybody is nuts about something, or they are "lifeless."
You know, we all have a right to be crazy, as long as we do not impose on others.
Only Walter gets to be crazy AND impose on others.

Hi Canuck,
Ben Syring is in charge at Hornady.
He is the "Custom Reloading Die Designer" by title.
I finalized an order for dies About June the 29th of 2011, and they shipped September 12, 2011, a month ahead of the schedule I was originally told to expect.
2-1/2 months instead of 3-1/2 months.
Refreshing!
And only $195.00 + S&H of $13.95 = $208.95
for something as exotic as the 12.7x68/49-10 aka .500/.338 Lapua Magnum.

I have been through the CH4D waits, and the Redding waits.
Hornady for me.
Excellent quality too.

Only question right now on this reamer is whether the shoulder diameter should be 0.5320" or 0.5310"?
Will add the throat and see what Dave Manson thinks of that shoulder diameter:

Will get something prettier than this to show to Dave Manson.
There is 6 thousandths of an inch of diameter taper per inch of chamber body length on this reamer.

Accurate Reloading.

As you were.

I do not think Dave will find any problems with this:



A rifle can be made, brass can be fire formed, then surely Hornady will make dies that make it all work.

Hopefully Hornady and Norma brass will both be compatible in this chamber with the same dies,
without any inside-neck reaming or outside-neck turning,
though real accuracy freaks may do as they please.
So I need to get some Hornady 404 Jeffery brass to try also.
