Got your attention?

No, the .416 Rigby is not dead.

It suffers from a 45 degree shoulder -- easily remedied:

Take my .395 Tatanka reamer and put a .416 pilot on it.

Change the 45 degree shoulder to a 20 degree one by reaming the .416 Rigby chamber just enough to be a "go" for the .395 Tatanka go guage.

This will sleek up the .416 Rigby and actually give it more case capacity and a shorter neck that is still longer than caliber.

Finally, the .416 Rigby has been improved.

Any .416 Rigby rifle can be fixed with a .395 Tatanka reamer with removable pilot, and .416 pilot. The original neck and throat will not be altered, just the shoulder angle and neck length will change.

Call this the ".416 Rigby-Tatanka" or ".416 Rigby-T."

Brass is made by engraving or stamping a "-T" on the .416 Rigby case head, after fire forming.

Just a thought while out on a Sunday drive.

Of course a Ruger No.1 in .416 Rigby would be a great candidate for either .395 Tatanka (re-barrel) or .416 Rigby-Tatanka by a simple re-chamber.

The Ruger No.1 would be great with a 26" or 27" barrel, in .395 Tatanka. This would make it as long as a 22" or 23" bolt action, since the No.1 action saves 4" in length.

Harry McGowen supplies a barrel up to 28" long at no extra charge, your choice of contour.

$180 for 4140 Chrome-Moly
$280 for Stainless
All are button rifled and cryo-treated.
1:12" twist is the only twist I have paid for tooling on.

The "GSC Contour" is a great one.

Get a 28" barrel and trim it back until the Ruger No.1 balances.

RIP you are on the job 24-7........

RIP! You're killing me!!! I have my 416 Rigby dies already! You couldn't have this Epyphony, say, 2 months or so ago? We could've had CHD wip up a cost saving multitude! Dude!!! I'm up to my arse in future projects!

458 AR

395 (ruger)
6.5 Grendel
550 Express (WTH)
500 AR (need a bigger bore long range shooter!

RIP, I missed all the preceding episodes on the inferior shoulder angle of the .416 Rigby. And I'm pretty pissed off that nobody told me about it until now, even though being misinformed has become a way of life since I had the misfortune to discover AR. So, what is it I get by changing the shoulder angle?

ahh rip...one of the few wildcatters who have it worse than i...

post pics when you get a dummy round

....the devil's workshop. Physician, heal thyself.

Do I really need a .375 Ruger, .395 Ruger, .416 Ruger???? Of course, the correct answer is...
When did NEED ever enter the equation?
Boomstick, I hate you.

..........Now if the 416 Rigby just had a belt it would truley replace the need to rechamber a rigby to 416 Weatherby........But it is a great step in the right direction........What is the Tatanka,s shoulder angle ???

PROF 242...I SEE A SWITCH BARREL IN YOUR FUTURE...WITH 4 TUBES...338, 375, 395 AND 416

After all these (what a hundred years...?) years, and on my fourth 416 Rigby with the factory Ackley-style Improved shoulder, now I hear that it is defective...what about all those thousands of dead Elephant, Rhino, and Cape Buffalo that now have fallen to a defective design? What am I to do?

Rich
DRSS

"...come here Momma, the hogs is got me..." Bob Wills version of Faded Love.

BoomStick, am it total agreement if that .375 Ruger in left hand comes out sooner than expected. Most of my rifles have an extra barrel or three.

prof242,
The sample .395 bullets are supposed to be in the mail to me now, with bulk quantities available after Gerard gets done with the AIM show in RSA.

I'll mail a sample .395/340-grain HV, SP, FN to any "Made Man" such as yourself, if you wish, when I get them. Just a teaser.

Upon further consideration, we need a rimmed .395 for Ruger No.1's and Searcy doubles:

45/120 3.25" necked down to .395
or
470 NE necked down to .395

Which of these shall become the 40 Tatanka Rimmed: 40 TR

Revived by special reguest:

The .395 Tatanka lives.
The .423 Rigby is in line behind 5 other 'cats in various stages.

I will post this lineup of dummies later this weekend:

.395 Tatanka
.416 Rigby-Tatanka
.423 Rigby

That rimmed .395 for singles and doubles turned out to be the .395/400 Nitro Express 3" Aboriginal. That could also be called the 10.03x74R.

We are proceeding at the usual snail's pace with R&D at RIP Arms, LLC.

Thanks RIP!!

RIP,

I think you've improved something that doesn't really need it. If you want higher velocity, just crank up the pressure. If you want really high velocity start with .416 Weatherby bases and take off the belt and push the pressure hard.

Is there a need for more velocity than is allowed by the standard shaped case?

Well, doing so and trimming back a few ten thou would allow you to use it in a standard action....

Who said practical or easy has anything to do with it?
This about ultimate perfection.
They will work better in full auto with the 20-degree shoulder!

The ideal candidate for the rimmed .395 would be the 500/416 case. A simple neck sizing would do the trick I'd say. The brass is made by Horneber.

You don't get it Mac.
400 Nitro For Black Powder 3-Inch had a .395-caliber bullet. Purdey bastardized the caliber to .405", and there was never a true 400 NE born of the predecessor BP cartridge, by increasing the bullet weight and powder charge to "Express Train" levels.

Same way the 450 NE 3-1/4" came from the BP then BPE then NE loadings. Ditto the 500 BP, BPE, then NE. Ditto the 577 BP, BPE, NE.

Modern powders and bullets will allow my pipsqueak to reach all-around status.
There can be only one true 400 Nitro Express and it has to be done with a straight-sided case (not bottle-necked), and it must be done with a .395 bullet, not .405, not .408, not .411 ...
Get it?

I got it! I didn't know there was a master genealogical plan for derivative provenance!

I'll make a .395" from 500/416 cases and call it the .395 DUMB "Der Uber Bastard Mutt". No chance of anyone thinking it's a "proper" wildcat.

Oh yeah! I gotta write up this genealogic eugenics and get it published in a gun rag for posterity. At least there is AR.com.
Cheers!

The 500/416 necked to 395 would be a 500/400
I would think you were more of a 577/400 kinda guy Mac...

Although a 500/400 sounds cool...

400 grains@ 2400fps in a single shot Ruger#1 would be cool, kinda like a 416 Rigby.

I'll leave that one for you Boomer. The .666" Teufel dies are almost ready. The tooling for the .666" FN's is about a week out. The .475" Teufel Rimmed cases and slugs are ready to go on the machine and I think I am finally getting close to having the 2-Bore V2.0 cases & 3500 Grain FN's done.

I called CH4D.
The last time they sent dies out for heat treatment was in October 2007.
The 400/.395 NE dies have been sitting, awaiting heat treatment, for at least a month.

I hope the addition in sheer mass of the .666 Teufel dies to the batch awaiting will get it rolling toward heat treatment soon, and the 400/.395 NE dies with it.

ideal combo would be 577/500 necked to .400 ... that is the true 577/400, and MINE .. nah, ya'll can have it

OH YEAH!!!

I'm gonna git me sum 700/577 cases from Dieter and neck them to .395" and make me uh 700/400!!

So take that Y'all!!

The 500/416 is getting Rigby performance so the 500/400 should be a winner.

Long range PG and DG with oomph...

But after seeing the light compact doubles used for the 9,3x74 it makes me want the classy 400 NE

Yeah, we really need to change (improve) the .416 Rigby, it just doesn't work, everybody knows that and a wildcat is always a better option!!

Hi Ray.
You obviously don't get it either. If you want me to kiss yours, then you can kiss Ol' Spot too. Mine and the horse I rode in on. Should add some color to that white 'stache of yours.

Left to right, all with 20-degree shoulder and 2.900" case length:
.395 Tatanka
.416 Rigby-Tatanka
.423 Rigby
.458 Rigby

Thanks again!
