This is the big thing for us Aussies .50 bmg primers are a pain to get here and there to dear !!

Can the .700 Nitro Brass made by betram be shortened to fit and have the rim turned off and an extracter groove added ??

How many rounds could the PH hold and could we get 2300-2400fps from the 1000 gr woodleigh if this where possible.

At the moment I am cold with anything on the .50 BMG case.......................although I do have a 160 or so of them.

Cheers PC.

If you are interested in having a magazine-fed bolt action rifle in 700 caliber, you might look at AHR's 700. There are a few people on this forum who have them and a picture and details on AHR's site.

If you redid 700NE you'd have to find
a way to headspace.Like a belt, like mine.
AHRs are beautiful guns,but pricey.
That diameter case works better with bmg size
primers for dependable ignition with the
powders you should use. Not having to
use starter powders. My 700s are headstamped
with no bmg name on them, and I will have bunch of reamers done with one at Pacnor for Karl
and a few others to get set up with
barreled actions. .I think we can
find someone to import finished cases, as long
as there isn't a military designation on them.
I can put a bushing in to use regular primers
as I did on a couple, for 12GA FH testing.
Just some extra expense and time.
Also I will have specs at CH4D for sizing
and loading dies. Ed

Ed rocks!!!

Even if you pay $10 per case, thirty should last you an Aussie Lifetime. Cut back on visits to the RSC for a month and you can afford that many.

If size is a concern, the AHR is actually a .680" diameter bullet. I will be shooting it three weeks from Saturday. Ed's is the full monte, .700".

Ed,

my friend and I might be looking at a barrelled action...........maybe yours is the go if we can get a bushing put in for the primers as long as that wont weaken them and blow them up !!

Bullet diameter .700 in (17.8 mm)
Neck diameter .728 in (18.5 mm)
Base diameter .780 in (19.8 mm)
Rim diameter .890 in (22.6 mm)
Case length 3.50 in (89 mm)
Overall length 4.20 in (107 mm)
Primer type Boxer

With 10 thou taper and 20 thou shoulders this could work...

keep the rim and base @ .780"

kinda like the 577 Trex.

700 Mastadon? cant wait for the cloning to kick in

PC- The bushing will take anything the case
will and cases easily took 40 psi in 12ga.
In one test my cases took full load of
Blue Dot and a lighter bullet, and extracted
easy from my test barrel. The bushing is
behind the bmg web of the base, with
only pressure fron flaskhole.My cases
shipped to you may be in the 10-12 dollar
range for import and all, and many times
less money than machining on 70 dollar NE
cases. I plan on after a few fellows are using
700 and others planning to, that we will get
a couple runs of brass made.There and here.Ed

Ed,

Still wondering if this I something I want to go through with and wondering I f just buying the action in the first place and then the .700 Barrel and just waiting until a run of suitabel brass is done By Bertram Brass...........is that what you guys are talking about ?? A case thats a copy of yours with a standard primer size made by Bertram ?? or similar company ??

Its just that its getting harder and harder to get stuff from the states and its a real PITA.

PC- that may be a good way to do it.
Just have barreled action ready.
Bertram is making bigger cases and much
better quality, and we'd have him to do some
for you,Karl, and friends, as there is
great interest over there. And have Jamison
do some here. Maybe in both primer
sizes, small for sure.I can test safe loads
with starter powders for everybody.
Everyone factory loading these large case
sizes with their recipes, don't talk
about them much. Ed

Ed,

my friend and I are Paying for our MRC's tommorow.......are all MRC PH's going to be the special larger thread size or do I need to specify that ??

An important requirement for us (and I assume Karl) is;

Bertram Making Brass (have you spoken to Bruce Bertram ?)
Being Able to Use Woodleigh Softs
Taking Normal Primers (I'd rather learn how to do a starter load and filler etc. than to have to try and obtain the big primers when I needed them.

When and whom do we buy .700 Nitro barrels from and at what price ??

The reason I was dubious was that I remeber how painful building the .585 was and getting all the stuff together and this looks as though it is going to be more difficult and a much harder road

PC-- Ask them to get you the larger barrel thread.They may have them all large thread.
Pacnor has barrels and I will have a reamer
there if you want them to chamber and headspace to your action.
There pricing is on web site and seems to be about $320
for a 1.375 or 1.5" 700 barrel. Chambering, headspacing,
truing action, etc, listed as $250, but may
be less as I am furnishing reamers.
I think Karl is planning on
that. Maybe actions could go to them first.
And I will find a way to get
a few cases imported so you can shoot,
while we get a run going.And I'll put in small
primers pockets for you.
I have talked to him a little about different
cases.Emailed also. Discussed 4bores,etc
It will just take bunch of us lined up
to get run made. I will be sending him
info on my 700 before end of the month.
Doing some final testing on case expansion
and longevity. Ed

Ed,

I spoke with my smith (buily mine and another mates Nyatis) just before and he said he would prefer if he could just get the Actions, barrel blank, reamer and guages and he be incontrol of the project as far as his work goes. I just spoke with Karl and he feels this might be a good idea as well for us aussies as its so hard to keep track of where everything is at from here when things are going from shop to shop.

How long Before Bruce Bertram can be organised to make brass and make it to take normal primers ?? with .700 Hubel on the head stamp ??

PC-I will get an extra reamer made for your guy
there.Yes that would be better so that a whole bunch
of you can get guns made there.I will email Bruce
tonight, and get an idea of how long will take to
tool up.Ed.

Ed's 700 is cool, Penny (Pac-Nor) confirmed my order (barrel and chambering) this morning. Just waiting on June-July delievery of actions.

For barrel sizes, seeing that the PH is 1.505"
action diameter and cartridge does need some
weight, Pacnor sells 1 3/8" and 1.5" barrels. My
one Pacnor here is 1.5" tapered to 1.15". My other
is 1.375" to 1.10". It is easier
to get them long and heavier and take it off
than go too light can't add any on.And
with decent wt and length I don't think you
need a brake.Ed.

Dirk-- The barrels I got were straight blanks
and I tapered them myself.Both barrels are 32" long,
and I have 8" straight breech section,
then tapered them clear to the muzzle.

I was figuring that perhaps they could go
from MRC to Pacnor then to customer, but today talking to
my FFL guy thinks that they have go to buyer's FFL holder to get transfered legaly, then buyer sends to smith or it
can go to Pacnor.Anyone here know how this
works for sure?

As for the work Pacnor does, when it is done,you
or your smith would have to do, bluing,
stock, magazine, extra lug, and sights/scope mount.
The 1/4 rib, brake as extras.Still some to do...Ed

Ed,

My friend and I have decided we are getting to give it a miss for a bit..................not out for good but for a few months. I have hunting trip coming up and need to fund that before this.

Just to add,

I want to be able to buy cases from Bruce that takenormal primers when that happens I will then purchase an action.

If you guys go with a bushing, Pse thread it in. Dont press fit it. Very Very bad things can happen with any form of weak primer support. I've had cracked cups on CCI-35 primers nearly blow up my .50BMG rifle.-Rob

Yes the bushings I did I threaded in.
I found a brass fitting at hardware, that
works by reaming out bmg pocket a little,
threading it with a tap Ih happen to have, screw in fitting, face off
fitting flush, then a ream out the hole
that was in fitting to take large rifle
primer.The reamer sats od and the debth
so that primer has a shoulder to bottom on.
And the web of the case ahead of bushing
is still all there for great strength.
Just takes time and little dough.Ed

Ed,

IIRC you take possession of the action thru your FFL holder. After that, you are sending it to different shops for work, no FFL needed.
