Just finished a 577 T-Rex for a customer that I thought you might like to see. It's built on a Granite Mountain Arms action, 22" octagon barrel without muzzle brake, quarter-rib with dovetails for scout scope mounting, vertical-stack mag box, and a steel butt-plate. [IMG]

WOW! That'll be a thumper.
Very nice rifle Wayne, well done.

Cheers.

Beautiful rifle – bet it’s a thumper with the steel butt-plate.

The fore-end balances perfectly with the barrel length. If you don’t mind sharing, how long is it?

great work!

The forend is 8-1/4" long from face of receiver.

Wayne, VERY nice, as is your usual build. No brake or recoil pad?...I thought Superman passed away some time ago :-)

Just just a lovely piece of artistry, from butt to muzzle. What a hunk of walnut!

I guess the shooter will wear something for recoil
absorption. Why did the customer select THAT .585
caliber over the others available? It is a GREAT
lookin' rifle,and coming out of your shop it's a winner
for sure!

Beautiful build!!

Beautiful object, but what exactly is the purpose of a rifle that you can't really use?

I have some difficulties understanding why someone would commission such a job, expensive in time, labour and money, just to hang it on a wall or keep it as a conversation piece.

The fellow we built it for has quite the collection of big-bore rifles all the way up to 4 bore. He wanted to fill a niche with the T-Rex, and really, the T-Rex is the ultimate .585 caliber: nothing else comes close to power or WOW factor. He had been wanting to build the rifle for a couple of years but had been unable to find brass. He found 100 cases last year from a private party and away we went. We built him a 700 AHR just like it a couple years ago. Now he needs a 600 Overkill, don't you think?

Why do people collect anything? Why should it be any different with rifles?

Beautiful work!

I can just see that wonderful engraving on the buttplate impressed permanently in my shoulder.

Thank you.

Wow! That's one hell of a varmint rifle. Dave

It all hinged on finding 100 pieces of brass.
I hope it was the good old Horneber stuff that was highly touted once upon a time.

Simply elegant with the transition from round breech to octagon under the integral (I am sure) quarter rib,
with rugged and functional express sight and scout scope.
The beautiful square bridges will never be marred.


I can't say the same about anyone who would shoot full power loads in this rifle.
He might get marred for life.

How much does that rifle weigh without the scope?

For the sake of art, I sure hope that rifle never goes flying like with ...

One of Saeed's Champions with an original A-Square Hannibal The Cannibal T-rex: May The Torque Be With You!

wonderful rifle !
But would not shoot it !
...tj3006

Reminds me of jack O'Connor talking about the old man that shot the double rifle and had his false teeth fly out of his mouth.

man, that is just what a rifle like that needs- a scope

RIP,

The rifle weighs 11-1/2 lbs without scope. I regulated the sights from the bench using a Lead Sled with a 25 lb bag of shot on it and a bunch of Martha Stewart Terry-towels for padding. The load was pretty stiff, 180 grains of H4831sc with a 750 grain Woody SN. It lifted the Lead Sled clear off the table. No harm to rifle or shooter. Would I shoulder-fire it? No.

Nice looking rifle

Bitterroot,
Seems you have a good load.
H4831 will do it all in the T-rex.

If Superman wants a varmint bullet load, just for some variety, here is Mitch Carter's best,
a 650-grain Woodleigh with 193.0 grains of H4831, he tested for 3 shots at 100 yards, indoors, with a 6X fixed-power Leupold and a muzzle brake,
total rifle weight (on a BBK-02 barreled by Harry McGowen) was 14 pounds, 26" barrel and synthetic stock.
Velocity was 2539 fps from Mitch's 26" barrel:



For whaling, maybe a 900-grainer load similar to the one I shot this group with, coached by Mitch, 160.0 grains of H4831.
Two bullets grouped tight at 100 yards, by the third shot I was flinching:



Superman is likely not maxed out with only 180 grains of H4831 with 750-grainer:



My hair turned white soon after I shot that last group above in 2001, even though Mitch's rifle had a recoil pad, a muzzle brake, weighed 14 pounds, and I was wearing a Magnum Past Pad.
The torque is still there, and the lighter the rifle, the more it tends to want to fly, like for Saeed's Champions.

If you pucker real tight and not flinch, these ultra-big bores will shoot amazing groups.

Since we're on a 577 'kick', I bet a lot of you haven't seen the compilation video I made many years ago of Saeed's 577 shooters. I added a soundtrack and it still makes me laugh...

That was a sick joke that Saeed pulled on those poor souls. None of them, except for the last guy, had any idea of what was about to happen to them. It looked like most had never held a rifle before. I hope no one got hurt.

What an absolutely beautiful rifle! Now, Spielberg should have posed with that one for sure!

i give up. why would anyone want to shoot a rifle that offers a real possibility of a detached retina, cerebral hemorrhage, or a broken clavicle??? is permanent injury something you pursue for fun? please enlighten me...

We're men, that's what we do.

I think the real possibility of any of those injuries occurring are way overblown. I broke my clavicle and a bunch of ribs riding dirt bikes. I guess we shouldn't do that either?

If they are overblown, then why shoot from a lead sled with 25 lbs of ballast? real men would shoulder the sucker and fire away from a bench.

I had a original A- Square Hannibal in a TRex and sold it a few years back. I think the guy I sold it to fired it once. I have not missed it. That butt- plate while a work or art could create a great bloody tattoo! Might never go away!-Rob

Rob, the customer has some type of strap-on device either lace-up leather cushion or sissy pad. He's not a novice and knows what he's doing. He just doesn't like the look of rubber recoil pads and it's not like he's going to be shooting it on a regular basis. He'll probably shoot it a couple of times then hang it up and go shoot his 4 bore or 700 double.

Big Doggy 700..?

650-grain Woodleigh with 193.0 grains of H4831

My top 650gr load in the 585HE, 200gr H335 in an Enfield

with 30" barrel. Test gun 14 lbs, Over 2" nice thick pads.

Thick pad on the stock and thick slipon padover that/

Gun locked onto 200 lb weight on my standup bench. 3000fps.

Did all my hairy load testing that way. Ed

Loved it until the part about the steel butt plate.

Beautiful gun. I'm just not a fan of. The caliber. I think even Bigdoggy 700 has only fired a few of my old Heym .600NE loads. There is a limit to how much pain anyone can endure!-Rob

Even with a PAST on, I can't look for long at that magnificent monster! The buttplate itself looks painful...

I love that barrel! I am actually considering a build like that albeit with a recoil pad and a slightly less manly caliber. Beautiful job Wayne.

Shooting it on a bench is just nuts!

The recoil of the Trex wasn't a problem. It was the crappy A-Square brass. If you pushed the load the brass stuck in the chamber and you had to use a mallet to open the bolt. You can duplicate and exceed the max loads of a Trex with 750 gr bullets in the. .600 OK without needing a mallet. I think Eds .585. HE is the best of the big .585s-Rob

Well I can easily go to 2600 fps and no high pressure indication with a 750 grs bullet in my 577 Tyrannosaur with a 23,5" barrel.. I find the design flawless.. I only use the good quality Horneber brass I bought 500 of some years ago.. Bad brass dont make the design bad..
I will never quit mine, but must admit that my 500 AccRel with 21" barrel and 8 Ibs is my preferred ele rifle from now on launching 570 grs -600 grs CEB and North Fork FN solids at 2300-2350 fps...
