Has anyone successfully got a .416 RUM or .416 Steyr up and running? Inquiring minds (with no projects at the present time) want to know how they work. The Rigby is a great cartridge, just a tad too large, IMHO.

If you're looking for ballistics, the RUM is about the same as the 415 Dakonta, off the 404 case. Easily achieves the 2450 fps or whatever you like from a 400g bullet, with lower pressure than the Rem (H&H case.)
The Remington does the job, but I alwas liked the loks of the 404 case, and the thought of having a little more room than needed.

John Noveske built at least one 416/300 WSM and several 458/300 WSM's.

You know, the 416-284 (~.50 at the base, 2.1" long) would be smaller than the 416 Taylor (.511/2.5), and the 416 RUM (.550/2.85) would be even bigger than the 416 Remington mag (.511/2.85). Quite a span there.
Whatever you're looking for, someone's done it. The RUM/404 case will duplicate all but the high-pressure Rigby loads.

Ifin/whenin Bob makes it back, I might be building a 416/376 on a mexican mauser.

Jeffe,

You mentioned the .416 Steyr a while back, I don't have a need for a true stopping rifle but I'd like to add some thing a bit more capable to the gun rack. Right now that tops out at 9,3x62, .405 in a #1 and of course the ultimate buff killer - Marlin Guide Gun.

Back to reality, something that pushes 400gr .416ish bullets to 2,200-2,400 fps in a rifle small enough to actually carry all day.

I wish you'd get that Steyr built so we know it works.

Rick,
you could always grab a ruger 77 in someting MAG, send it for rebore and have it chambered for 416 taylor.. generally about 300 bucks.

you would probably have to shorten the barrel a hair, as it would get pretty thin, in most cases, but a 22 or 20" 416 T would be light, easy, and pack a whallop

jeffe

I've been looking for a 77 in anything magnum, seems to be a dearth of them around here. Douglas even has a reamer in .416T and 4 or 5 bbl blanks laying on the shelf.

I'm curious if the .416/.376 or the .416T makes the better cartridge once you figure parent cartridge availabillity, ballistics, magazine capacity and ease of feeding.

416 maverick looks good, what do you think?

Attractive looking little cartridge, Lazzeroni is claiming one up and three down in their action. I found a reference that it's @ $100.00 per box of 20 rounds for factory ammo.

The .416T is looking more and more like the real deal from a cost stand point or I may just build a .458WM since a good friend gave me a set of dies in that flavor and it shares bullets with the .45-70.

yup...416 taylor and 375 taylor should be a factory cart (minus the belt please) go for the taylor, it has lots of fans on this site

The Dakota is 540 base and body diameter and the assorted Ruger mags are .532/.530.

Is there any factory loaded and chambered big bore powered cartridge that fits everything listed below?

Bigger than 40 Caliber
Has a .532 rim and smaller body dimension
Without a belt
Short enough to fit in a factory Ruger sized action
and
Gives true big bore capability?

Fjold,
You've got the idea

The Steyr cartridge has a .496 rim and .501 body, plus it's beltless, hence my interest in the .416/.376 wildcat. Wonder how many you can stack in a standard Mauser magazine? Unfortunately, after playing with load from a disk it looks like it may only push a 400gr bullet to 2,000 if you're lucky.

I'm calling this the .40 Something Sansabelt Magnum.
Using Fjold's basic specs and looking for 2,200 fps / 400gr bullet / .40ish caliber.

At the risk of sounding like a broken record, I'll say it for the third time in a week:
416-9.3x64mm Imp!!! It's a 416 Steyr "long." AKA, 416 Taylor beltless. AKA 416-45/90 Rimless.
It ought to act just like the Taylor.
There's 50 caases on sale in the classifieds as we speak....

does anyone have this?

someone run this on quickload and check the stats on this please

also can someone do a quickload on a 375x64 brenneke

I think the attraction of the .376 Steyr as a parent cartridge instead of the 9,3x64 is that Steyr brass is more readily available in the US. If memory serves, some of the 9,3x64 shooters have had trouble finding good brass.

Correct me if I'm wrong but it shouldn't be a big problem for a capable smith to change the bolt head on a '06 length action to fit either the Steyr or x64 and then it's a simple rebarrel no matter which route you take.

is it me or does no one complain about the rebated rim of the 64 brenneke?

what are the case volume diferences between the steyr and the brenneke?

I love the 376 and I'm thinking about the 416 Z-Hat because I have magazine limitaions. Otherwise, the 416 x 64 sounds like the way to go!

I have a 416 Aagard (416/376) but don't have it stocked yet. I'm hoping for a little better than 2000 fps with a 400 gr.

The 9.3x64 doesn't have a rebated rim, per se. Maybe 5 thousandths ot something insignificant. Similar to the Jeffrey.
You may be thinking of its bastard child, the 284 Winchester, about whose rebated rim much has been said on both sides.
As to whether someone has it, pretty much everything under the sun has been done. Its performance is not a mystery though. In a slightly blownout configuration it will hold a wee more powder than the Taylor, with a wee less bolt thrust, and should certainly be capapable of 62k psi loads in a modern bolt action.
400g at 2300 would be likely. I've heard of people getting 2350 with the Taylor, but that sounds a bit scary to me.

can someone post a pic of the 416 aagaard please...is this pretty much a straight case with taper? who has one and what do you think of it. thanks

Belts are what make the 458 win,lott, ackley and watts WORK.. as well as the 470 capstick, 510 wells, 500a, 550 magnum and 550 express WORK.

Belts are rims pulled up for headspacing.. or rims are belts pulled down for.. no, wait, i dont want to finish that

I can hook you up with an EXCELLENT 7 remmag ruger 77, not mk2, tang safety, in FANASTIC condition

jeffe

Jeffe,
Thanks, but I'm a Mk-II kinda guy.

jeffeosso...do you have a 416 aagaard?

Boom,

I don't think many have seen a .416 Aagaard cartridge. Mr Mehaffey has a barrel and action but didnt' mention any ammo.

If after getting built it didn't work out a fellow could rebarrel to .376 or 9,3x64 and only be out the barrel costs.

Dangerously close to talking myself into a project...

loping a 416 bullet in a short action and no belt...what is not to like?

belt is like a long haired girl...

some like, some don't

can that be a sassy long haired red head with pouty lips daisy duke leggs and, and, and...

paladins post was entitled "sansabeltmagnum"

jeffeosso...can you make me a 416/376 dummy round? i'll pay for it.

Hi

Have You considered usig the 8x68S as base? I´ve seen an article on a 375x68imp used in Africa, very impressive. A 416x68imp would at least duplicate the Taylor performance and still fit in a std Mauser.

Regards
Heavydane

Stig,
Welcome to the forum.

The 8x68S is an interesting case from what I can see on Load from a Disk but unless it's radically improved it holds about ten grains less water than the .416T and only two more than the .376 Steyr.

Jeffe's right about the belt, unless a new case offers better feeding or more magazine capacity or improved ballistics the .416T is probably the best idea.

What's the magazine capacity on the 8x68S in a normal Mauser magazine? I believe the .416T is 1 up and 3 ready? The Steyr is 1 up and 4 ready?

http://www.lazzeroni.com/ct_sacart.htm

paladin...any thoughts on the laz 416 maverick?
or the 416 wsm?

Well, that's the thing.
Going from .522" to .473" leaves alot of room for "improvement."
Intersting to note the similarities between a blow-out x68 and the Newton round. (And a shortened Rigby for that matter!)

Didn't really finish the thought. (Getting old?)
With a .522" base, and even the same taper as a belted mag it will come out on top, though if you like you could get away with even a little less taper.
Say, around a 2" body, 30deg shoulder, .40" neck, 2.5" case, 3.34" COL, and .504" at the shoulder base. The belted is only about .511", but needs .532" for the belt, so as fas as magazine capacity, you're looking at .01" LESS for the x68 case....
Now, whether you can find a good supply of cases, another matter.

That's one of my concerns, this needs to be on something commonly available in the USA. After a bit of checking, .458WM isn't exactly common but .416T can also be made from .338WM I believe... .376 Steyr brass runs about $20 / 50 from Midway or Cabela's.

Oh well a local store has a nice used M-70 in .416 Rem for sale

Its almost a simple clean up job to take an existing 416 rem chamber out to 416 RUM and then just neck up 375 RUM brass. I did this a couple months back in a Rem 700 APR and fitted it with the 375 RUM magazine. Feeding is fine and there are 3 in the hole.

I took Speer 400s gradually up to 2600 fps with AA4350, and just quit. That's enough power, even if there is more. I have yet to scope it, but the shot consistency was outstanding at 12 fps SD.

It has all of the strengths and weaknesses of the 416 Weatherby without the belt. There was never an easier wildcat to load for: just stuff in 416s into the 375 RUM and lightly compress some 4350.

Recoil is a dead ringer for factory 458 Lott 500 grainers.

Hi Guys, If Stig or Stigge as he is know to be called elswhere is the Stig that I know and is regard higly on the http://www.robsoft.nu forum and http://forum.robsoft.nu/viewtopic.php?t=24915&highlight=stigges+hemsida where you can see some of his work or his webbpage: http://www.specialvapen.se/galleri.php. This guy really can put something nice together when he works.

PS Knowing Stig/Stigge by reputation and through the webb he is to modest to blow his own horn hence this resumé. Ds

/Best regards Chris
