Would a 577 Tyrannosaur safely chamber in a Ruger No. 1 if rebarreled would it actually fit in the gun or is the case to big?  To be great, is to be misunderstood. | ||

Not sure there is enough "meat" in the feed tray to allow it to be milled down enough for the shell to slide into the chamber for one thing.  Doug Humbarger NRA Life member Tonkin Gulf Yacht Club 72'73. Yankee Station Try to look unimportant. Your enemy might be low on ammo. | |||

Two or three years ago a poster owned a #1 in 577 NE. It took a little more than just a barrel job but not too much. Can't remember all the little details. "Experience" is the only class you take where the exam comes before the lesson. | |||

major thread diameter of the ruger is what, 1" ? less threads and .680 (?) for the trex case... or less than .2" per side of barrel thickness. there's more than one reason that the trex is generally on an enfield.... jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

If someone could figure out for me if it could be done. Id be more than glad to build this rifle and of course be the smuck to shoot it.....call it a weakness but I like big ass guns  To be great, is to be misunderstood. | |||

positron, I do not know how similar it is in size, but J.D. Jones of SSK has made a ruger #1 in his 600 JDJ. I think it is a 577 necked out to .620. It may be about the same size as a T REX, but it has a special heavy barrel on it and gives off around 8500 ft. lbs. of energy. | |||

If you want recoil you can rebarrel it to 550 Magnum without a great deal of trouble. With 700 gr bullets at 2400 fps it is also in the 8500 ft lb range. Same case as your 460 but blown out to 55 caliber. If you ran it at Weatherby pressures you could probably up the fps to 2500. Fun o'plenty! Tore my rotator cuff last month with mine.

We are getting 510HE cases made now at Jamison Int. Use 50 cal barrel, rimmed case, over 3.55 inches long, straight case, brass lasting many reloads, and 8500 ft lbs is just light starting load with 600 gr.Can go to almost 12,000 ft lbs.Case specifically designed for #1...Ed MZEE WA SIKU | |||

You could chamber a No1 to 577 Nitro. That would give you more chamber wall thickness though still not as much as would be nice, and possibly weaker brass than the Rex. You won’t be able to load this as hot as a T Rex in a bolt action but I’m sure you could achieve recoil beyond your desire to shoot. The Nitro Express is much sexier and seems appropriate in a single-shot. Marshall Jones | |||

Alan Hall, down Clanton, Alabama way builds what is likely THE stoutest DGR single shot actions you have ever seen. He, of the BR Hall actions and former partner with Ed Shilen (also designed the Shile DGA). I expect even the Huber line would all fit on one of these. 1-205-755-4099 last I heard. regards, Rich | |||

Suppositron... I'm guessing you're 23 years old, +/- 2 years. Do yourself a favor, and quit trying to blow yourself apart with recoil. You're doing your shooting a great injustice. Anybody can get behind the latest 877 Brontosaur and pull the trigger. That only proves you know an ever diminishing amount about shooting big bores. Not that you need a PhD from Nitro Express U., but a little common sense will go along way in developing your ability to shoot large, heavy cartridges. Your 460 Weatherby not that bad??? Awesome!! Once you've nailed down MOA accuracy with it, and do it with boring regularity, then move up in caliber. I do however expect that by the time you're that good with a 460, you will have grown up enough to know better than to want a 577 built on a #1.

Im behind you 100% no matter how old or young you are!! I say build it and be sure and post us some video clip! I went through the same thing you are. I ended up with a 600ok and have enjoyed it greatly. Im now trying to acclimate myself to the price tag of a Searcy 577. This may take a while! Good Luck, KP Double Rifle Shooters Society | |||

Ed, I spoke with Alan Hall this afternoon. He is, sadly, not in production of his falling block action any longer. He is pushing 60 and slowly easing into retirement. Sigh........... Rich | |||

Wow Mancannon was right about my age I was 24 at the time when I posted this,but now Im 28 and after 4 years of college, and 2 years in my career. I still want a 577 Tyrannosaur, not sure if I want it in a Ruger No. 1 though. But I guess there is no cure for stupidity! KMG3000 aka Positron | |||

Not a matter of stupidity, just a matter of wanting to try something different and asking people who might have walked that road for some assistance. Absolutely nothing wrong with moving ahead on your project. The Big Bore forum is filled with astounding feats in huge calibers that "can't work" except many of us have used them with great success.

If you have advise to give then be nice and give it without belittling others. For over a decade I have also been hashing, rehashing, and played with the idea of building one. Many have told me and as previously posted here a #1's chamber walls would probably not be thick enough for the pressures the T-Rex operates at and this makes sense. Also, #1's are too light, it would be difficult to build the Ruger heavy enough for the recoil. I have learned so much from the people on internet gun boards I hate to read negative posts. Every time I ask about the T-Rex all the answers either say a GMA action (too expensive for me), a Bauska (can't find an affordable one), a MRC Professional Hunter (still hoping), or a Winchester Enfield with a P-14 bolt. If brass ever becomes available again I will stock up. The one gunsmith who has been recommended to me for this more then once is Marshall Jones (marshall@jonesfort.com). Does anyone else have any suggestions? That being said, the .600 Overkill makes so much more sense and it's name is second in coolness only to the .577 Tyrannosaur. But, guns are like women. Who know why one loves one and not another. It is what makes it all interesting. Decisions, decisions, always decisions... Kmg3000, PM me and we can compare notes. | |||

Well where I am at right now is I have the barreled action of my Ruger No. 1 packed up and ready to go to Pac Nor for rebarreling, if on Monday when I talk to someone in tech support about choosing between the 500 asquare or 577 t-rex, and they tell me the 577 cannot (or they won't build it) I will have a barrel made up and installed on the action chambered in 500 asquare, as posted previously for some stupid reason these are the only two cartridges I like, go figure? | |||

500 A-Square works great in the Ruger No. 1. I have done one. Make the barrel a straight 1.200" diameter shank/knoxform for 6" then straight taper to 1.000" muzzle diameter at 27" muzzle ... Then the rifle will weigh 10.5 pounds dry, with Ruger walnut. Bell and Carlson makes a rugged synthetic for the Ruger No.1. Add 4 scope rings, picatinny base on that barrel shank, and a scope and bipod, and a screw-on muzzlebrake, and slip-on recoil pad and you are up to 13 pounds in no time, and shootable for accuracy at 1000 yards. .577 NE works because the case is narrow at base, and it is a low pressure cartridge, enough metal in chamber wall for that. The .577 NE rim is the thing that has to be cleared in ejection past tang safety, safety has to be recessed. The .577 Tyrannosaur is just too big in base and too high pressure to be safe in the Ruger No.1 barrel thread O.D. Don't do it. | |||

I second RIP's post. FORGET a .577 T-REX in a Ruger No.1. If you want a T-Rex so bad why not just buy a A-Square Hannible in that caliber. They show up from time to time. The barrel wall thickness is far too little for full power T-Rex loads! My guess is it will eventually kaboom! Good luck finding Brass too. My advice is build yourself a 500a2 and learn how to shoot it! With 600 gr bullets at 2500fps they provide endless entertainment. -Rob Never underestimate the power of stupid people in large numbers to do incredibly stupid things- AH (1941)- Harry Reid (aka Smeagle) 2012 Nothing Up my sleeves but never without a plan and never ever without a surprise! | |||

Easiest for big power to put my 585 HE in a #1. More than a trex, and less the trough has to be opened up. even less metal to remove from trough than doing the 577NE. It is real long and in fallong block works great. I put it in a couple of FBW falling blocks already.The Ruger extractor works great with rimless belted cases.Ed  MZEE WA SIKU | |||

I'd look close at Ed's 585HE if I was seeking what you seem to be. See it: http://ammoguide.com/cgi-bin/a...BMHdjnAMOK&catid=699 Jack OH GOD! {Seriously, we need the help.} | |||

Yes. Agreed. And, the 585HE will fit in CZ550 or any other gun that can handle the 505 gibbs. It is the smallest head diameter for a 577 with undisputed adequate head space and body taper. There is a surprising amount of competition in the 577 space. Factory brass, we have that now, right? I believe AHR said they would be happy to build one on the CZ. I would not buy the time of day from ASquare. | |||
