Hey Guys... the 50 ae based encore has got my thoughts going.. (yes, JDJ did it with a .510 bullet)

So, does anyone have a drawing of the 50 ae? Or better still, let me buy a couple pieces of once fireds...

I would like to know the rim diameter and length...

here's my thoughts of the
500 jeffitto plinker

Mexican mauser action
50ae or 500 SW brass
loaded for 535 woodleighs or lead GCs

1200-1400 fps?
2"-2.5 oal

quickload, even though it complains about the bullet being .510, gets there with a 2" 50ae

Jeffeosso, why not use a 50 Beowulf? It is simply a lengthened 50 AE.

This is the 50 AE.

Rim diameter - .54"
Base diameter - 0.54"
Case length - 1.285"
Bullet diameter - 0.5"

Jeffeoso,
I shoot a 50AE in an AR-15 carbine. With the 325gr Speer bullets @ 1700fps using H110, accuracy is very good.

I also shoot a 50BMD (460wby case cut to 2", loaded round is 3.6"OAL) in a Sako that was originally a .30-378Wby. It shoots BMG bullets (or any other .510" bullet) from the clip (3 down, 1 in the tube).

I'll send you some AE cases if you want.

BMG

You're taking the backwards way around of how I came to getting a 500 Jeffrey 3 years ago. A buddy had a line on some long 50 AE cases ~1.6" that were being run for some bench rest guys who wanted a new short stubby case to play with. Anyhow, I thought it would be a neat little thumper on turk 98.

Well, I started looking for a barrel, and another buddy had a Douglas blank he'd planned on using for a 500 Jeffrey. I couldn't pass it up for $50, then he mentioned he was selling the 500 Jeffrey brass, and well I started to think about things, so I bought the brass, then obtained a P-14 action, sent it to Mr. Ricks, and ended up with something much more potent then a stretched 50 AE.

As an asside, the 50 action express uses the .500" bullets, but JD calls the .510" version the 50 American Eagle. The buddy that got me interested in the special brass used to have a 50 American Eagle Encore. He was able to push 600 gr to 1100 fps from a 14" tube. You should have no problems reaching 1200-1400 with a 535 gr from a rifle length tube.

"This is the 50 AE.

Rim diameter - .54"

Kent in IA,with all due respect,but you`re wrong
at this point.
Rim diameter of the .50 AE is .514",same as rim
diameter of the .44 Magnum.This allows easy
caliber conversion for Desert Eagle pistol owners
(no need to change the bolt)The .50 AE is a model
example of rebated rim cartridge.

AFAIK the .458 SOCOM cartridge is also based on
elongated .50AE brass,and has the advantage of
using bullets with much better BCs.

Regards

Jeffe- Go with the .50 Beowulf it has absolutely NO redeeming features at all( except that it will shoot out of an AR-15 and fits the mag)! It has an extremely rebated rim, uses LARGE PISTOL PRIMERS, Headspaces off the rim and takes .500 Bullets ( to get around probable california gun laws). It's apparantly not very accurate either!
Think of it, you can finally use a .223 boltface remington for something in .50 caliber!- Oh, I forgot, the bullets for it have exactly the same B.C as a flying ashtray for at least a 100 yrds.

Jeffe -

The elongated brass Paul H is referring to is likely our original batch of 458 SOCOM BASIC brass. I need to check, but I may still have some. It is 1.6"-ish long, has the same rim as the .308 and has the old 50AE head stamp. Got one sitting here that is fitted with the HAWK 700 gr spitzer in .510 caliber, and it's overall length is .... 2.81" ....

As Darth stated, we use it to make a 458 version, that gives a shoulder to head space, and formed brass is available. We use it with the 600 gr Barnes in suppressed AR-15s .... subsonic, full auto. (BTW, Rob, the rim on the Beowulf is the same as the 7.62x39, not the .223)

But looking at the project, and considering the action you're looking to use, may I suggest a different approach?

Take a piece of RUM brass and cut it at 2.000". Now you have brass rated for much higher pressure (65K instead of 35K psi), with the full size rim (less chance of bolt-over miss feeds ...), and in the straight wall version it should hold a .510 bullet just fine. But now you are talking custom dies, reamers, etc.

Depends on what you want to do. Cheap and easy, go with either the Beowulf or the 500S&W. More expensive but possibly more versatile, go the other route.

Or wait about 2 more months and let me tell you about a crazy project we have going that would fit your needs quite nicely.

-RobMarttW- I just meant that Jeffe knows how to open the boltface of his trusty .223 rem to fit the mighty .50B. He needs to save his Mexican Mauser for a 404 Jeffe -Rob

MartytW - are you referring to the 510 Phalanx? I noticed that on your website. Will that be available in FAL style rifles? I am not too interested in an AR10, but a FAL would be interesting to say the least. By the way, what case is the 510 Phalanx based off of?

Yep, that must be the same run of brass, as it had the .473" rim dia. I forgot about that detail.

Rob - Figured as much, that Mexican Mauser deserves better than the Beowulf

Kent - The Phalanx is on hold barring lack of serviceable brass. Until we find a source of good brass, we are not doing anything with it. Now, the other project, we started it for the AR-10, but with DSA bringing out a new FAL, we may need to give them a call. And Jeffe's bolt action might like this round too. The project sponsor would like us to hold off releasing details, but those that have seen it are intrigued by it ....

I just found something `bout the .458 SOCOM
This is velocity and accuracy chart-.458 SOCOM
fired from a 17" barrel(Tromix AR upper)

Corbon 300grs JHP (FL) 1839fps 1 1/2in./100yds

*-subsonic load
Interesting thing is:
A 300grs Barnes X after smackin` a heavy steel
plate expanded to 1.25" WOW!

All groups from the bench off sandbags at 100 yds

I`d really like to know the BC of that Hawk 250-
grainer.(velocity!!! )

All above info taken from article by D.M.Fortier
".458 SOCOM:Monster Sledgehammer from Tromix"
GUNWORLD April 2002
"The new .458 SOCOM cartridge was developed by an
associate of Tony`s Maarten("Marty")P.ter Weeme.
Its development was a result of an informal
discussion with a senior member of the U.S.
Special Operations community following the Task Force Ranger debacle in Mogadishu,Somalia
as described in the book 'Black Hawk Down'"

MartytW..is that you?!

"Yup,just look at my signature line at the bottom.

OOPS! Now I See it!
Thanks for the heads up!It`s an honour to have posts with you.

How about .416 SOCOM ??
A stout load under a 400grs,416" Barnes X-
BC-546 !!
Seems like good recipe for a big bore,flat shooting,hard hitting cartridge!

God bless the victims of 9.11.2001
We`ll never forget!!
