My next project is a Hubel 700, single shot. I think I've figured out a muzzle break that would rival or beat JP Ent.'s idea, but wouldn't deafen the shooter. Gotta try it. Anyway, I need a 50bmg action to get started. Money is definitely a factor, but strength is the focus. Also, who'd be best for chambering and fitting a PacNor for it?

You need to talk to Ed about this.

There's the bochard(sp) and hagn actions. Talk to Ed or Rob
jeffe

mmpyro--The actions jeffe mentioned will work.
Rob's Borchardt is beautiful gun.
Also a McBros.Being it is belted case
the ideal that I like the best
is a McBros bolt action. I will be getting a
State Arms to test with in next month
as it is less costly. Still a strong action
and a shellholder type action.I have
barrel chambered, and a stock. Its a
big thumbhole stock I found on ebay.
With hairy loads in it, thumbhole is best.
Maybe Pacnor will do work for you.
I can send anyone the chamber drawing
so they can have reamer built.And it is
the chamber specs that will work as
I have fireformed in the chamber.
Now as for the brake, please try a long barrel
first, like I have on 12GA FH. You need wt
and getting the muzzle heavy helps recoil.
I watched tailgunner shoot my 12ga FH and
he handled it like a 243.It has long barrel
and right balance, with same kind of power.Ed.

Ed,

the Borchardt action Rob is using is bigger than the original, isn't it? Where does he get them?

Rich

Idaho-Yes much bigger as it was designed for
bmg. Borchardt Rile Co in NM. Al Story design.
505-535-2923. Ed

Thanks Ed, I'll contact Borchardt this afternoon, seeing as we're only a couple hundred miles apart... Also, do you have a barrel in mind besides Pacnor?

nmpyro - my barrel is a Pacnor and super nice inside. Never looked any where else for
700 barrel.You might check Bauska,
Badger, and Kreiger.If you get Borchardt
or McBros actions set up to do bmg,
the extractors will work with no changes.
You are planning on the full length
700HE? Ed

Yes, around 27-30 inches. No use loading powder you don't use. Can't decide on a nice laminate stock or rugged synthetic though pretty and heavy -versus- versatility.

Mr. Hubel,
I just spoke with Penny at PacNor (I guess it's hunting season up there, by the way), I think I'll go with a 30 inch barrel. Also, if I can get hold of him, I'm leaning towards Mr. Story's Action and Stock. Thank you for the references and advice... I'll let you know when I need the Chamber Specs.
P.S. Can we get together to get 10 or so empty brass?

nmpyro-Yes I can get you 10 cases.
Email me. And I will start supplying others
also.For now a limit of 10 per person.
Asking same as 12GA FH- Which i was getting
10 bucks 4 of which is shipping.
So 700HE case 6 bucks-bullet 2 bucks
plus shipping(bullets cost over $2)for
single dummy for collectors.Total 12 bucks
for case, bullet, and shipping for one.
And for gun builders, bless their bravery,
empties for loading 6 bucks ea plus shipping.
So ten would be $70.That's the starting
price for "one" 700NE.I have a bunch done and
have got grinder jig setup and fireform barrel made so will speed up making cases,this winter
and those shooting can get more down the line.
But your not going to wear a case out unless
you shoot 1000 gr at 4 grand all the time.
I know you will like the Borchardt.
And don't get a fast twist barrel, 1 to 20
or 22 will be fine. Your going to get
better velocity, thus get fast enough spin to stabilize 1000gr bullets.In fact that twist will do for 1500 gr bullets.Ed

anybody got a picture of this borchard action ? or dimension info ?

is this a falling block action or am i confused ?

tomo577- Yes it's a big falling block.
Here is picture of Rob's in 12GA FH. Ed

Other actions that guys building 700HE
suitible for full pressure
may want to check, is Bat Machine bmg
actions. If I wanted to run moderate
pressures, I could switch barrels and bolthead
in my Savage that has 12GA FH. But no
reason to, right now. State Arms at 850 bucks
will be a good test rifle. Some companies
AR uppers for bmg size cases, are decent
prices also. With the time I have now,
I can make about a thousand cases this winter,
so that should get a lot of pyros
in the heavy recoil mode.Ed.

McBros also makes a 3 shot box mag repeater action. I built my first 700RLG ( My version of the .50BMG blown out to .700) on one. Worked great and even fed surprisingly well. Huge flat nosed 1000gr BRIDGERS that would go through anything! Pac-Nor has my original barrel profile design, consider it carefully as alot of thought went into it. twist rate etc. Be carefull about the thickness of the muzzel, cause even at 24 inches you have enourmous pressure remaining. I just drilled a lot of 1/8 inch holes in the end of the muzzel with an indexing head and it worked fine! Later we added a Vias style brake. Buy McMillians TAC stock to make it portable. In the end it weighed 18 lbs and was shoulder firable. For a hoot I put a Eotech holographic sight on it(McBros actions come with weaver mounts) and had a ball-Rob

Gentlemen,
I just got off the phone with Mr. Story... He has an actrion 90% completed that he said I could get (starting at $3000). But he needs something from the ATF to be sure it's classified as a sporting cartridge. 3 questions Mr. Hubel...
#1 Do you think I could get a copy of the approval (or maybe send it to him)?
#2 How can I send you some money for 10 cases?
#3 Do you have chamber specs, so I can get started having a reamer made?

Thanks for everything guys, I can't wait to get a sight picture on this thing.

nmpyro-I will send him a copy of approval letter
from ATF Tech division.And to anyone else who needs one.You can send pmt to-
Ed Hubel
7455 W Stevenson Lake Rd
Lake, Mich - 48632.
I will send you a chamber and case drawing
along with cases,with my toll free
number on the drawing so that reamer
guys can call if any questions.
My # 877-551-2605. Ed

Mr. Hubel, Got to thinking. For my first 700, I might not want to drop $3K on the receiver. Called State Arms and will fax the FFL to him on Monday, Pac-Nor has my specs and is just waiting for the go. I want to triple check everything first. State Arms said the barrel shank needs to be 1.440 X .720 long (before threading 8tpi), Pac-Nor says that sounds too short. I tried to explain that the casing is outside the receiver, but maybe I'm missing something. Also, I sent you a check for some cases and specs, let me know if you need or can think of anything else. Thanks

nmpyro-- Yes that's the right size and length
shank. 1.44 by .720 long.Threaded 1 & 7/16
by 8. Plenty strong as it is much larger than
the biggest regular bolt actions.My Savage with 12ga FH has 1.120 x 20 thread,
and it is only .870 long and a third
of the thread has 3 machined grooves through
for the tooling that did the bolt carrier
grooves.And it's ok.You should let whoever
does the threading and chambering cut the
shank. Just get a blank from Pacnor or
they profile I think for same price.If you
have them profile to match action make it as large as you can and look right with action.
State's 50 cal guns have barrel breech dia of 1.625 inches, but go heavier if possible.
And have muzzle 1.3 in min.
You'll need the weight.Ed

Just out of curiosity -what are you using the 700HE for? Or is it just a thing you like to have?

Anway you look at it you need guts to pull that trigger!

Thanks Mr. Hubel. Man, I tell you, this would go much faster if my work schedule didn't keep getting in the way. Pac-Nor's already closed... so I'll get it ordered in the morning. I think I'm going to go with a cylinder contour (for extra weight), 30", 1.75"Dia. Thanks for the blank suggestion, makes sense. I'll let you know 'bout the progress.

Cewe - I'm trying to plan on a Mongolian or Russian "safari" in a couple years, other than that, I can't give you a "makes money sense" answer. Bigger, Badder, Better, and it helps to be the only one around

cewe- First as the developer of the case
I want be half as famous as Elmer.
But seriously, a way to get much more power
than 700 NE at a small fraction of the cost.
In a bolt action for great strength.

nmpyro- Yes I think looking at pics of State arms actions that 1.75 in at breech
will look just right.Ed.

Just ordered my barrel from Pac-Nor. I think (as I don't have a lathe or mill, sucks huh?) I'll have State Arms chamber and mount the barrel up there.
Next question... good reference for a reamer? I have to wait for the specs to send (unless someone already has them from you), but it seems like it should all come together pretty quickly.
Anyone know a good shoulder surgeon?

How about a Farq? I don't know who made it, not mine, but it's a 700NE:

Waffenfabrik Hein makes an action for the .700NE that should work also. If you look hard on e-bay you can find some .50BMG actions like the Maadi-griffen that would work pretty well.-Rob

That big Farky would be nice, but is more than
the Borchardt I think.Sure would be nice
to have.. Besides the 700NE it
could do 700HE, 12GA FH. Ed

nmpyro-- The funds got here and the cases
and cartridge and chamber drawings should go
out to you on Monday.Manson Reamers can
do a good job and I can talk to him
anytime there are questions.He is down the road a couple hours drive.Ed

Thanks Mr. Hubel,
As soon as I get the specs, I'll send them. Not long now!!!!

Mr. Hubel,
Got the casings in... AMAZING, scared me just looking at the case. Can't imagine looking at the muzzle. Defintely excited to get this gun finished. Thank you for the "sample", That's a lot of brass around there. I'll let you know when I get with State Arms. Adios

could you pleasae post the website for State Arms?
thanks
Rich

Rich www.statearms.com

The sample nmpyro is referring to is
a sectioned case, to show the thickness
and strength of our 700HE case.I know
they will last many firings like
the 12Ga FH.Ed

Rob,just got back from Africa and was thinking of a 700NE for the next trip!Do you have a few pics of the gun.Will the Granite action work as I want a "lighter " version,maybe a 22" barrel and total weight around 12 pounds at most.3 or 4 shot would be fine with qtr rib,banded sight,etc....What you think? Tom

The .700 in your post is a "Mastodon" Action by giles Whittome of London, he built rifles on that, a smaller (.400 bore class) and an even larger action upto 2 bore.

The 2 bore action was a close copy of an Alex Henry sider hammer falling block harpoon gun on dispay in the Royal Armouries Museum in Leeds, West Yorks, England.

I do have a some more info on Whittome rifles including the .700 if you are interested.

If the weather cooperates(no rain and
a little sunshine) tomorrow we will fire
off the first 700HE Test rounds over the
chrono. Been a long time comimg.The one
on the right in picture.First is a
458 Win, 2nd my 458HE,3rd my 510HE.Ed.

Whoo Hee--700HE. Shot some 850 gr Woodleigh
hollowpoints. I made them hollowpointed
to get 1000gr down to 850 gr for the first
session. 260gr of W-760, 2650 fps.. 300gr of
W-760, 3000fps.. 300gr of 748, 3200fps.
300gr of my H335 blend 3450fps.
I made a screw on breech from
a 10 lb 2' nut, u-bolted temporarily my
chambered barrel on a 150 lb I-beam mounted
to my tall 400lb shooting table. It has no extractor, but didn't need one. the 760 and
748 loads the case slipped out with my
fingers and the 335 hotter load case come out
with real light pry from a short screwdriver.
The case rim and 2/3 of extractor groove
protrude from barrel like in bolt rifle
so it is easy to grab or pry out.
Case showed minimal expansion, resized
easy, just one fired 8 times, used to
see how many times it is good for.
With that weight of bullet can't get enough powder behind it to stick a case hard.
Unless you used Bullseye.Ed

Ed,

850gr bullet at 3450fps! Yowza!!!

Great job and keep the reports coming.

John

Saarfikid- way to go dude! Just got back from TEXAS! I would talk to Waffenfabrik Hein about their .700NE action. I think it just might work. A Borchard will definately work as will a Mcmillan. I have a reamer too. Send me a PM and we can take privately.-Rob

I want to see this scaled up to take
700HE, 12ga FH, 700NE, 50bmg, Rob's 700, etc,
or even 4bore, 8bore,20mm, 900HE.Anyone else
interested jump in. Were going to give it
a try. Ed.

you'll be able to use synthetic furniture. That chunk of steel is going to weigh thirty pounds by itself!!!!

Man, i need a PH with a huge bolt to do the 700 DA
