Hello

I've got a completely idiotic idea. I will let construction of a Rugen No. 1 to something really serious. I bought a No. 1 Tropical 375HH that I intended to use for this purpose.
I know there is one who built a 577Ne on a No1. So that is my aluminum, but the question is if the box is capable of 577 T.rex sleeve alt 585 Nyati sleeve. A No. 1 in cal 500Ne would be nice and smooth right, but now I have a big gun.
Excuse my translation, but perhaps it goes anyway.

Do you have any good ideas?


Sincerely Michael

I might add that I will probably use 577 or 585 cal because it is the biggest I can get on via Lothar Walter. It seems difficult to get hold of a pipe 600 from USA because of export regulations. My own theory is that the boundary lies somewhere between 577Ne and 577 T-Rex if I refer to the diameter brass

the 577 NE, with horneber brass, can be loaded up past human tolerence in a #1.. no need for a trex

Thanks for your answer ;-)

But,,, you mean that I can get up to speed with 700 grains bullet to a T-Rex have? At least I nearby. Do you have any examples of charges?

I like the 577NE. I wish Hornady would offer loads.

Here in the states. SSK Industries does Ruger #1's to 577 bore.

If the 577 NE works, then why couldn't the 585 Nyati also work on a #1? Or does the rebated rim disqualify it? (Not that I have any desire!)

You can put my 585HE long case in the Ruger #1
easier than 577 and it will outrun the T-rex.
With my case more clearance in the trough.
The Ruger works with rimless cases perfectly.
Here is picture of 2 FBW falling blocks
that I put it in and Ruger will do also
as well...Ed

Here is a good suggestion. Whenever the words .585 NYATI enters your brain, lie down immediately until the thought goes away!You will thank me later! The .577NE is a much much better idea. No the rim isn't the issue either.-Rob

But you are right, as always..

. Helo. and thanks

But ,,,,, Robgunbuilder you tell me to forget the 585 Nyati, do you mean when oxå me to forget the 577 T-Rex? I understand in every way that it is easier in every way to build and get the stuff into a 577 Ne. Here in Sweden there are not any, I have to crawl all around the vorld vide. I refer to Reloading dies and brass, where should you buy such a sensible thing to cost?

Swensken, both robgunbuilder and Jeffe, are telling you. That a 577NE will give you ALL of the recoil you can handle in a #1, Plus it is easier to reloaad than an Nyati.

And extract.

585 Nyati is a prick of a cartridge to extract compared to the 577NE.

Yes, it makes sense what you say. It is getting so that I would ask that the weapons maker in the kammra 577Ne. Everything speaks for it. One or two rebound damper piston in, what do you think?
No one who wants to recommend where I can buy caps and tools??? Anywhere, as long as it is simple and that they have it at home ..

Sincerely Mikael

I would avoid the T-Rex and .585 Nyati like the plague. I own both and they are the least favorite of all my big bores. Both cartridges are a PIA in many ways. The .577 NE will give you all the recoil you can handle and we know it works in a Ruger No.1. I dont even know if there is anyone making T-rex brass anymore?-Rob

I have a #1 tropical, in 458 Lott, I'm not sure I would want something bigger in a 9.5 lb rifle. I would try and shoot one before you built it, Or You might end up with a used rifle for sale with only 1 shot out of it.

on trex - i think jamison is planning on a run.. been hearing that for some years..


the 577 NE is "only" 19gr smaller than the trex. same bullet. If you use ANYTHING other than bertram, you can get nyati speeds .. bertram will probably get sticky.....

if you want a monster in a #1, the 577 NE is the answer ... but its going to be LIGHTweight, and a monster ...

Well Rob, You are probably right but I dont agree.. The 577 TRex is a nice design in my opinion. I am on the other hand not as experienced as you regarding building big bore rifles. I have never noticed a single problem with my rifle in this caliber. Easy to load for, easy to get 2500-2600 fps with a 750 grs Barnes Banded solid and 2400-2500fps with an 800 grs GS solid. Can reload brass more than 20 times with max loads if I anneal brass every 4. time..
Only problem is a rifle weight of 13 Ibs and severe recoil. Not my favorite to drag around in Zims October heat chasing elephants.. But nice to have around when going into the really thick stuff where visibility is measured in feet rather than yards..
In real life I am dead certain that there is absolutely no practical difference on elephants between this cartridge and your 600 OK. Thats the only reason I havent build me a 600 OK yet.. If your 600 had seen the light a year or two before I might have chosen it, but I am not sure.. The 577 works wonderfully

And by the way - Dieter Horneber can still make anyone a run of 577 TRex brass if they need it..
I dont cause I ordered a lifetime supply a few years ago for the same reason..

I've thought long on this, but I do not really know what I want. But I am leaning towards making it a 577 Ne.Vad do you think about weight, I can control the weight a bit by how serious I am attaching a pipe. 7kg I say, is it too little?

Friend of mine had a 577NE built on a Ruger No1. The struggle is to keep weight up. With a lightly profiled Lothar barrel, x2 mercury reducers, replaced stock bolt and every other trick to add weight ... its barely 13lb. Amazingly mild to shoot even when loaded with 750gr at 2150fps. But ... I dont think you want to push the Ruger No1 action to the limit with a case of this diameter. Match classic 577NE velocities and be happy!
Cheers...

Anyone know how much chamber wall thickness you have at the base off hand? I am not near any of my specs.

SSK has thier 600JDJ which is just the .577NE with taper taken out. It's tickling the toes of the .600OK but I sure as hell wouldn't want to shoot it in a #1.

I'm with trying before you buy. Pulling the trigger on a rifle that has +6800 foot lbs of recoil is a lot different than effectively hitting a target with that amount of energy in a normal weight rifle. My under 10lb 500 Jeffery is a real shoulder puncher after about 10 rounds. Hence my recent purchase of a 450-400 double that shoots like a tame pussy cat all day long. YES I LOVE RECOIL but work yourself up to it. I routinely warm up with a few full steam 458 Lotts before I jump on the 500 Jeffery train. Yes its a lot of fun but work yourself up to it slowly otherwise you'll have a nice big rifle in your gun safe that will collect a lot of dust rather than hunt a lot of game.

Brad

take a look at saeeds new trex shooting videos- there seems to be a new #1 in them

Buffalo- I have to admit I like the T-Rex cartridge much much more than the NYATI. The issue for me is the A-square Hannible rifle I have for the T-Rex. Awful gun that reminds me too much of Art Alpin( rest in pieces). The .600Ok with 750gr slugs will still beat the T-Rex with same bullet weight. -Rob

I shot a #1 in 600 NE several years ago. Ten pounds was not enough, but for once I was in agreement that a brake was necessary.

I am quite sure Rich is being perfectly accurate!

I always thought the .577 NE had the max rim diameter to put in a No.1....?

Yep,
600 JDJ is just the 577 NE necked up to 600, taper begone!!!

RIP,
Yes, but he DID refer to the 600 NE....

It's a pussycat & mine weighs 10.5lbs

Just the thing for goat! and I'll bet its a stopper..

Hello Svensken

Here is my 600 JDJ Ruger No.1

Its my "fun-gun" addition to my Dangerous Game Rifle collection.








The 600 JDJ is one of JD Jones' creations from about 20 years ago. JD wanted to put the power of a 600 Nitro Express, into an affordable Custom Ruger No.1 Tropical. Although the 600JDJ caliber is actually a 577/600 wildcat cartridge, (577 NE opened to 600) its case capacity is exactly the same as a standard 600 NE, but with the head dimension being reduced by .035" and the case length being slightly increased with a slightly smaller rim dia. So, why not then just chamber the Ruger in 600NE? That extra .035" barrel wall thickness and the smaller rim dia., adds a lot of strength to the finished rifle. "Full-House" load is 1900 fps with a 900g bullet.

Correct me if I am wrong but I believe the action can be opened up and rethreaded to allow for a larger barrel shank diameter. I have a #1 in 500 3” and it makes for a good woods rifle. Kile on these threads shot an elk with it at 200 yards with no problems though.

A big problem with going any bigger than the .577 NE rim diameter is getting a Ruger No.1 extractor to work.
The .600 NE is 0.050" bigger, won't work.

The problem with using a barrel shank/knoxform greater than 1.130" or whatever goes on the Ruger No.1 diameter is the forearm hanger.
Even 1.200" is too big without some modification.

My 20 Gauge Ex Purgatorio 3.5" on the Ruger No.1 failed because the rim is bigger than a .577 NE rim.
The 20 gauge rim is only 0.766" in diameter. Too big to work.

The low pressures involved with the NE cartridges with the skinny barrel diameter on a Ruger No.1 knoxform makes it OK for .577 NE, or .600 JDJ.
Using a straight cylinder contour for the entire length of barrel should be considered.
About 1.130" muzzle diameter.
The .585 Nyati or .577 Tyrannosaur would be dangerous in the Ruger No.1.
Not dangerous to game, just dangerous to the shooter and bystanders.

One of these days that 20 Gauge Ex Purgatorio 3.5-Inch may get built on a Sharps 1874 replica from Pedersoli.
That action can handle a bigger rim than the Ruger No.1,
and shotgun pressures from purgatory, with .615-caliber/920-grain lead slugs.
But I am having too much fun with other things right now.

Due to the limitations of chamber wall thickness if you want maximum power from a No. 1 go with the 550 Magnum, which is just the 460 Weatherby case straight out. It's also the easiest conversion. Since it's a 460 case you can run it at 460 pressures. I cannot, however, even imagine the recoil with full power loads.
