i talked to rmc they said they could/would make brass

So you called Dave Casey and he told you he would make 577 T-Rex Brass for you? 20 Pieces? That's interesting. Please confirm. Maybe I'll have him make my brass since he apparently has some new equipment at his disposal.

yes im pretty sure i emailed him some time at the end of 2010 and asked for either 20 or 100 peices of 577 trex brass . i just sent him another on last nite . i will post what he tells me . i didnt see a price on betrams website for 577 trex just all the other BB's .if not i can get it made locally pretty easy . But id rather buy brass from someone who specalizes in it . Im pretty optimistic about the MRC .

What would your local guy be "making it" out of ... I'm asking cause there would be quite a few folks in the inductry who'd like to know how that works. By all means let us know what Dave Casey says re making T-Rex brass for you.

Best way is to make an order from Horneber.
I ordered 550 pcs of 577 TRex brass to be done with it for my lifetime...
Excellent brass.. Can`t get any better than that.

theres a college teacher here who is a machinist , hell he even machined out parts and built his own lathe lol . in his spar time he builds minture functional steam engines . and he did the papper work for a serial number and built a 50 bmg from raw material exept the barrel he doesnt have a barreling machine . he could make my brass shells from the right brass monoblock .Also ive been think about what ROb said about the 600 ok. jamison has readily availble brass plus tooling cost for a rifle is easei(R) than that of the trex. i shoot some ideas to MRC about a rifle and what not . RMc makes brass for tapered shells according to their price list they have the 577-450 listed .and 43 mauser which i think is a necked shell. i will let you know for sure within a few days .

Look- Machined brass is good for 38,000PSI max period! I've made brass rifle cases and so has Macifej. Our lathes cost 100k and hold .0001 or better all day long. We are both real world CNC machinists not some guy with a home made lathe in his basement.
Machined brass cases will let you run a TRex at 1500fps or so, duplicating the mighty 45-70 or there a bout. You need Drawn brass to withstand pressures greater than that.Period. No body we know of will make you 20-100 pieces of Drawn brass for a near extinct caliber. Do you have any idea what the tooling costs are for that? Yup you could contract with Horneber and pay thousands for 500-1000 rds and wait a year or more and also deal with the import issues or you can take my and others advice and go with a proven and safe approach.
Finally, read my post on the sticking brass issue. My guess is Horneber brass won't stick at the same pressures. Everything else does at least in my gun.
BTW- push machined brass over 38kpsi and it won't stick it will just go boom! that's why we use drawn brass cases.
If you have to have a .577, call AHR and buy a .585 AHR. Your better off with a .600ok and I should know as I invented both cartridges, but your not listening anyway.-Rob

I wanna see how someone' would make a T-Rex case on a lathe ...

Rob,
ah, i think you can gert 20-25kpsi on turned brass .. but NOT loaded past 577 2 3/4" nitro for black levels in a trex

Jay - watchign them make it would be fun, the first case ... wathcing them shoot a 50k psi load is something i would do from behind a blast screen.

Hey guys, remember "rule #1",

Keith

Jeffe- Turned brass cases can work into the 30kpsi range but lower is certainly better. If I were to make a turned bottlenecked case, I'd turn a long straight walled case,then anneal and neck it down in steps with hand dies. I'd then do a final fire forming step in the guns chamber. That's a lot of work for a extinct cartridge. Yup 50kpsi in such a case would be a real bomb.
hog killer,I fear your right. -Rob

Why would the turned case be a bomb?

It has to do with brass strength. In making
regular drawn cases the annealing and drawing
process with the machinery, more than doubles the
strength of the brass, where the lathe turning
of regular brass bars to make cases doesn't
add any strength.It has a lower strength rating,
less than half of drawn cases. This rating is
especially critical in the head area of the
case so that it won't blow out.Ed

OK, thanks. I think I understand.

Four of our best, (Macifej, Robgunbuilder, jeffeosso and hubel458)
have contributed to this thread and the guidance is top notch! I
just hope you all don't ever get tired of straightening guys like me
out when we stray off the proper course.

Bigfivejack- it's not about straightening folks out. It's about experience. I've made tons of mistakes and generally learned from them and the ones others have made. I've actually built these guns myself as have others here. I may come across too harshly with some, but I don't suffer fools well in real life either!
The TRex seems like such an attractive cartridge till you get into it. Then you find it's just a can of worms and a money pit for the unwary. I do my best to give folks good hard earned advice and sometimes they listen and sometimes they don't. I spent a ton of time on developing the .600 ok to avoid all the issues with the .585Nyati and TRex and it has met all those goals. AHR has the recipe downpat and delivers the guns in a reasonable timeframe with no problems at a reasonable cost. I continue to recommend them highly.-Rob

I surely do not get offended at your
style. I have learned so much here from
the guys who post their experienced
based info. As long as that goes on here
I'll be around to benefit.

Rob may come down harshly here sometimes (and in my opinion for good reason) but don't let him fool you, he's a great guy in real life.
And don't think he's b-s'ing you about the things he's done and has - I've been to his place and I've seen the toys/tools/equipment he has - he doesn't talk about half of it. When he says "Been there, done that" from what I know and have seen, he has.
Plus he has a lovely wife to keep him in line

Well I do have a wife that I would

not trade for any other. But these other

"things" that our experts have, and the
knowledge that they have, I wish...

I would like to emphasize this point. The .600OK as designed by Rob and executed by AHR is an incredibly easy setup to deal with (not counting the recoil!).

Sorry ive been to tired to logon . But yeah ive been reading about,the 600 ok it has,what 11,000 ft lbs close enough to a 50 bmg but in a rifle that weighs 1/3 as much . I havnt seen a stock I liked to much on the gma action guns . Oh, I seen some 750 gr .620 bullet shouldnt it be close in velocity to the 50 . Mpi is,the only company who coukd make the stock,i want . Dont know what a barreled action would cost . I can get a 505 gibbs action from mrc for 1300$ mpi stock 900$ barreling cost ? 26" , no sights laminated gloss blue. With stainless action

Damn! All this talk about the T-Rex got me all hot and bothered...I just bought one tonight! Nice rifle...almost new with way upgraded wood. I recently sold my 600 OK and 700 AHR to a guy in Austria, so I had an excuse. I'll be getting over 200 cases with it, so I may be offering some up for sale.

will the 600ok or anyother .640 rim fit in a 1903 springfield ? found one locally for 650$ and that is one of my favorite rifles it would be cool to have a bigbore 03 with a made for it mannlincher stock .

Wayne at AHR would know, as well as others here.

Biebs,

Do you actually ever shoot any of these behemoths you buy and sell? You seem to go through them like fiber through a colon ...

Sure...like you, I have a lot of trees on my property that have a very high lead content!!!!

High velocity lead poisoning

Oh yah- a 1903 springfield is perfect for the .600ok. I think an even better idea is to start with a Ruger 10/22.-Rob

Does the crowd detect a hint of sarcasm????

For those on a budget, a type 99 Arisaka action is frequently used to build 505 Gibbs and T-Rex's. few experienced gunsmiths fear taking a Dremel tool to such advanced fireams technology. No one has talked about this option in 20 years or so but it's as viable today as it was then. Few have been successful with the M1903 Springfield due to fear of defacing us property, although hope springs eternal! Art Alpin first choice was the Arisaka but they were not as plentiful as the Enfield and cost more. The ground mums also negatively affected the aesthic design of the Hannibel. Art also considered the Moisin Nagant action, but after a successful raid on Bannermans island in the late 70s secured ample supplies of his beloved Enfield. He was arrested and convicted of dastardly deeds soon after.

For that much if you furnish barrel, we do real power, 585HE,
one of Enfields here and that includes dies and
bunch of cases. Done it in NEF, bunch Enfields, Mauser 98,
Ruger 77, Olyarms BBK. a PH, FBW S, and FBW L.
Now doing in CBC and Khan and 87 Win. Later in Ruger #1
and Sav 112 and more. I'll even do an Arisaka if one
is around reasonable. Ed

I really like thelooks of the type 99 an it is, claw extractor even the mighty rem 700 doesnt have a claw . Id like to keep that stock and old ww2 look but,have a big bore. ive seen them on gb for 100,400$. Hubel what that 585he look like . also will the 600ok fit the arisaka.i didntthink ithad a very ling action considering the 7.7 is only 58mmlongshell

Either can be put in Arisaka, as it is
like a Mauser action and I got 585 in Mauser.
You have to change bolt stop, bolt face, and open the
port. 585 is longer and here is picture
of one with 505 Gibbs. On the right.
Same loaded length as the Gibbs. Now
all of this is easier of course, with less crowding,
in an Enfield for couple hundred. Enfield about inch
longer than Mauser,Arisaka,Carcano, Mannlicker,etc.
In Mauser it is singleshot and Arisaka
would be about same. Smith here got 3 extra Enfields.Ed

so its a 577 ne with a rimless belt ? where the 577 trex is a blow out case with a neck and a huge belt . i here the 577's / .585 ( why are 577s really a .585 ? . are legendary for penetration . one guy who hunts with a sxs 4 bore told me that on a cape buffalo hunt he shot one with a 577 ne and it passed though it and it one behind it . he said the guide was pissed . As for the enfields i just like the looks of the type 99 id keep the bolt handle like is no bend just have the internals bigbored and barreled and have the stock refinshed in blonde or a bamboo color have it rechannled for the bigger diameter barrel .but the thing is cant i get 600ok brass from jamison whenever i need/want it but the 585HE would be custom order through you ?

ed
you are being lead along .. let it go

He is the one that gots to buy action, barrel,
if he sends to smith, through me, I got reamers,
and sell him dies and cases.Furnish load data.
I sell dies from here for exact same price
as they cost CH to make them and send
them here and CH just run off some more.
Trex is just a rimless, necked case, no belt.
Just .030" bigger on the base than 577NE.Ed

Just wait for the new run of Trex brass to hit the market and order a bunch

I should have some new Horneber 577 T-Rex cases next week, if anyone needs some quickly.

i need ~10, if you can spare em, i'll be happy to buy em

Jeff, will do. I'll let you know when they arrive....they're shipping next Monday.
