Here is picture of 100 cases loaded with CEB solid nose bullets
and hollowpoints. This bullet is a turned solid with wide meplat
or wide hollowpoint. .

Image

Here is picture of triball loads that fellows like for deer and hogs,
and just general tear em up fun, with using BPGS seal to improve
sealing under what are heavier loads. The balls are .600" and
315gr. each. The wadcup is a TUPRW123 that Precision sells.

Image


Our 585 caliber is modern bolt action continuance of the 577 Nitro
Express rimmed case, that many big game hunters like, usually
set up in double rifles. It has an interesting history, from the old 24ga
size to 577NE, to 585 Nyati with G&A picture of Ross Seyfreid
shooting one in a Ruger #1 under recoil knocking his shooting glasses
off, to the Trex of internet fame knocking guys over with recoil,
to our 585HE the strongest yet.

The 577NE is an offshoot of 24 gauge caliber paper cases, only they went
eventially to brass cases. Back in the 1860-70s, starting first with short
cases and black powder, cases built like shotgun cases, called the
577 Snider, then going to coiled brass cases, still with black powder,
then on to drawn brass cases, called 577 BP Express. then to 3"
and other longer cases with smokeless. The Snider started out with a bullet
of .570" diameter and through the progression to the 577NE bullet
diameter ended up at .585". This general bore diameter of cartridge guns
and muzzle loaders, it is really interesting on how they developed
and were used by military and then hunters over the years. The Snider
was necked down to make the 577-450 , a military round used all
over the British Empire, by the tens of millions.

Bases of both 24ga and 577NE are about the same. Now we have made a
24ga FH, a slight regression to earlier times, by taking 577NE brass, and
reducing rim diameter to 24ga specs. Two minute job. And
stamp the caseheads 24 ga.

For shotgun upgrading in power and range, It is all about increasing
the power in easy to find brass cases, stronger actions, and finding
reasonable price rifled barrels. Same barrels we found for 585, work for 24ga.
The 577NE brass we make 24ga drawn cases from, for example are
about a third the cost of 600NE brass, or getting turned 24ga cases made.
We could use 24ga thin cases but they are a pain, expand way too much,
with slug loads which makes resizing without crumpling cases a problem.

Info about the power in types of guns normally set up with 24ga FH,
break actions, bolt shotguns,etc. In thin brass 24ga case, 440gr slug
goes 1500, with about 2000 ft lbs, that's in a 2.5" Magtech brass case.
Now using the better, heavier 3" brass we got, we can increase speed
to 1750 fps increasing energy 50%, going to 2000 fps about doubles
energy. And going to 2300 which good brass holds ok, in heavy barrel
gun, gets us near 2 1/2 times the energy. About 37-40,000 psi which the
actions hold in this smaller diameter case, compared to 12 gauge size.
So makes relatively smaller bore shotgun, 24ga, with 458WIN power.
.Perfect with Minie bullets. Perfect for deer and hogs, bear, etc.

Great for slug hunting in shotgun only areas. We mark barrels 24ga
and cases 24. A decent case that is complimentary to our 585HE....Ed

Guys asking about using 585 CEB bullet in our 12ga super
sabot. Here is picture, We just took off the bottom band and couple
middle bands on the CEB and it fit perfect in our 12ga sabot,
which uses .575" slugs. Hollowpoint one pictured 700gr in the
sabot loaded in brass case. Can be used in plastic case with a
special made hollowed out long roll crimper.

Image

Getting some more interest in our 585HE.
An application for our 585 HE is for guys with old military 14.5mm
PTRDs, to use our case with chamber insert. In many places 14.5
cases are scarce, real expensive, as well as most 14.5mm cases
being steel are not the easiest to resize/reload. Our case sizes
like regular cases and can be easily reloaded many times.

And a PTRD with almost a 5 foot long barrel could get 650gr
spitzer bullet to about same speed the 14.5mm gets a 900 gr using
3 times as much powder. About 3300 fps. Or get a 900gr at 2800.
Great possibilities for fun shooting. For tactical use in a place
where it would be useful to reload in the operations field, where
steel cases are scarce. 100 of our cases do over 2000 reloads.

Image

I like Enfields to put our 585HEs in, for reasonable cost guns, the
actions once sporterized are one of the longest for long cases. .
Here is inexpensive way to fancy up the Enfield Bolt handle by
cutting the dogleg part of the old handle off and welding on
inexpensive contoured handles I found, one of which is like
Ruger 77 handle, the one on the right . Something even a novice
like me can do.....

Image

A lot of guys are crazy about CEB bullets. Here are light 450gr
ones in our 24ga FH. That hollowpoint can range in weight 450gr
to 700gr depending on how much we cut off the back..
The 24ga FH brass case is nice complement to our 585HE,
for shotgun only deer hunters that want a .585" caliber,
and easy to find big bore bullets.... Ed

For lightweight plinking, deer hunting, etc, in 585HE as well as 24ga FH
here is picture of 58cal Hornady sabot that holds .451/.452" light
bullets 225 to 300 gr. A way to shoot targets economically. Low recoil
but a big bang and satisfaction. A 250 gr bullet would go about
mach 4 with a top load..

Image

Here is what 585 bull barrel, target blank looks like, 1 5/8" OD and 32" long.
It'll go in heavy action of some kind. 4th one from the left. The one in yellow
sleave on top, is a heavy contoured one with muzzle of .980". we got a
bunch of them and so does McGowen.

Image


Here is picture, nice cast bullet I like for the 585HE and 24ga FH.
It is .585" diameter and 650 gr and these particular ones are a
hard lead alloy, plus they've been heatreated. They are about as
hard as copper jacketed softs pivtured. These in .575'' size would
work in our 12ga sabot..

Image

But to penetrate good and do great damage to game or target they
can be fairly soft lead and hollowbase like Minie Bullets. Here is picture
of timber drilled through with .585 soft lead Minie from 585HE.
Picture is the back of 6x6 timbers where Minie bullets came out.

Image

Guys experimenting with multiple ball loads in 12ga wadcups, here is a
way to keep them together group wise.Ed

Here is picture of our NEF 12ga FH with Hogue Compstock. It has the
recoiling cam and springs in the hollow butt plus some weght,

Image

Here is a variety of slugs and bullets that fit in the 12ga dangerous
game slug, lock on sabot. BPI sells that DG slug.

.Image

There is couple 585 videos on Swann Gunsmithing's Facebook site;
Of our 585HE in first Ruger #1, that was done in Australia.It was set up
for the poster Tankhunter on the AR big bore forums. That gun killed the
first AUS buff, killed by a 585HE, that I posted picture of above. You can
go direct to the page and click on the videos to watch the test firings..

https://www.facebook.com/swanbarrels/videos


Here is picture our 585HE in a Montana PH action in a MPI stock, with the
style of a CZ stock and metal will be finished with a Gun Kote finish.


Image


Here is picture of a 585HE we did in a Mauser 98 as a
singleshot test gun. We used a composite stock we
adapted to fit action. Weighted to 12 lbs.
Enfield in back, you can see it is longer.

Image

And speaking of singleshots a fellow in the Yukon is
just finishing up one in a Ruger #1.And the 24hr Campfire
forum has over a million views of this thread, ..ED

The 12ga FH isn't the first wildcat case built on BMG brass, it was preceded by
target rounds like the necked down 338 Talbot, the cut off 700 DKT for big game,
necked down to .416 and . 458, and more, but the following one was way
before them, in my favorite rifle caliber, for .585" bullets.

One of first modern era 585 caliber wildcats, since WW2, the 575 Miller-Greiss Magnum,
was first mentioned in the fifties, It was made from BMG brass shortened to 2.70" long
and necked up from 50 cal to .585". But actually if cut off first, it would be annealed, necked
down to hold 585 bullet. Fairly sharp shoulder.

They rebated the rim quite a ways down to .618" to maybe fit 98 Mauser bolt.
Maybe used a special hogged out, reworked action. Listed as
shooting 750gr bullet about 2400 fps. It holds about 150gr of ball powder under
a 750 gr bullet, maybe little less than 3" 50cal spotter case, where our 585HE holds
180gr under a 750gr'.

We made one for experimenting on a full length BMG case.With rim left same as the base
and would need a BMG or PH sized bolt and action. I'm glad to be a big bore wildcatter,
and happy to be in the company of big bore nuts, old and new. Years ago when guys did
big wildcats on BMGs, they took what was available, full length BMGs to rework, and but
maybe back then they could have used the 3" BMG spotter case, by shortening the neck,
if they could have found couple barrels full.

But it takes a lot of work to reform and shorten cases that much like M&G, with the multiple dies,
multiple annealings, and case trimming and extreme reworking of regular rifle actions,
which is why I like our 585 case, simple and straight, any regular, long bolt action, or
falling blocks, break actions, etc, a 585 good for dozen or more heavy loadings,
and moderate loads, last forever..

For our 585HE , made it a size, actually new belted size, to fit regular size, long bolt guns,
(not BMG actions)that didn't have to be used from tripod so to speak, and could be put in a favorite
gun of many, the Ruger #1, other falling blocks, without taking metal out of the feed trough.
To get the same and/or more powder space as a cut back, really shortened, BMG case, like M&G,
wildcatted to 585, or other short cases, we made longer case and worked with guys
with a group buy, to get a factory run made. A miracle. We thank all gun nuts for the help.

Here is picture from the great site, cartridgecollector dot net, of the M&G Mag .Ed

Sorry to be away so long. Health and money problems.
Here are couple 24ga FHs break actions, a CBC with monoblocked
585 barrel in it, and a guys NEF he had a 585 barrel monoblocked in.
The 585 barrels are perfect fit for 24ga, and 585 Minie Bullets
are a perfect for barrel and 24ga case fit.

Image

Image


Another matter---It seems strange for me to ask for help when
I ask guys on the net for help at times. . But I really am in a bind.

That is truth, Our small income disappeared from our farms truck
garden business, as my my knees are shot and can't hardly
walk, I can't do field work, etc. And the wife's lung condition
got so bad she can't work.. So we finally had to quit that,
but were and are in debt. We need little extra money to try
to keep our health fixed up and pay bunch of back bills and utilities.
As well as needed for traveling to doctors, treatments,drugs, etc.

Could you all maybe get together with others on these forums
and kinda take up a collection to help get me out of my troubles and
debt. Like 10 or so bucks each put into our paypal account as gifts.
And if you want to mail it, contact me to get you
my mailing address.

The Paypal email is je@gunownerstv.com

Best Regards- Ed

PS-- I really need help. Not astronomical amounts, but fairly fast.
Just a little from each to help. A quick boost so to speak.
We never made anything on the 12ga FH, etc, work and research.
The little coming from sale of 585 brass, dies, barrels,etc,
goes to pay to the places, where rest of the money
is owed, for getting them made..Ed

Here is picture of a lightweight Barnes bullet in 24ga FH.
Guys cut the back off of 750gr bullet off to get 500gr weight.

Image

Here is picture 58 cal Minie slug that's little long on the side for our 12ga
sabot, with the front of the slug above the grooves swaged to fit in
sabot. The swaged front third of the slug fits next to the internal ridge in
sabot and the sabot doesn't bulge out.Just run front into a die
and punch it back out.

Image

And some info about 12ga FH and other hopped up shotgun slug loads,
You know we use couple of the rifle powders, slower than shotgun powders, .
We like to use IMR 4759 for some loads and slower RE17 for others where
we have room for larger charges. Those two powders are ignited ok in large
diameter cases like 12ga, 10ga, 16ga, etc, without needing BMG primers.
But we have always been looking for easy to ignite powders of the RE17
type, in all temps, that has a speed between the IMR 4759 and the RE17.
RE17 uses different mfg process to put the deterrents in the powder kernel to
control speeds, which allows much easier ignition, because the deterrent is
not all on the outside of the kernel. RE17 ignites easier compared to 98%
majority of rifle powders with all the deterrent on the outside.

But there are some out there made by Nitrochemie Switzerland, who makes
RE17, RE26, RE33, etc, for Alliant. It's the ' RELOAD SWISS' brand available
for those folks in UK and Europe, They are called- RS 40, about same speed
as RE12, RS 50 & 52, about same speed as RE15, RE60 & 62 same as RE17.
Also one ' Vihta Vouri ' powder called TR140 available over there,
that Nitrochemie made..

Many guys can't get IMR 4759 anymore, some can't get RE17.
Be nice to get some of RS 40-50-52 powders or the V V TR140 shipped, if ever
possible, into the states, would really be great help for hairy slug load work.
But the guys in UK/EU now can load some real hairy, slow powder, slug loads,
we experimented with, even though not having IMR 4759....Ed

We got guys wildcatting our 585HE case,


Image

Here is picture of that 375 Warlord next to our 585 case he made it from.
He is going to make couple later necked down to 416, and 458.
There is another guy working on doing one necked down to 357 wildcat.

Image

Here is a picture of our poster Biebs on AR, 585 HE, in a MPI stock.
He used a big Enfield action, with a fancy jeweled bolt.

Image

We found couple other big actions for our 585, that can even feed really
long overall length loaded cases, like 4.5" long or more, if you are
using long pointed bullets for real long range target and hunting work.
One is Lawton 8000 Cheytac action, and the other is Stiller Cheytac actions
made similar, just a newer version. Both actions come in 1.45" diameter
and a 1.60" diameter receivers. Work for 24ga FH .. Ed

Here we kill two birds with one stone so to speak,

Best case sizer is the MEC Collet Super Sizer and it can double
as a case holder when we roll crimp. Much better hold than
the ones made to hold cases for crimping, that cost a lot.
Save cost of a holder, plus have best sizer around

Image

Here is couple different setups our guys checking for our 585HE
in a long, Lawton Cheytac action. First laminated thumbhole stock.
Second in a Hogue Compstock. The action can mount a scope rail
like shown on the table in 1st picture or a receiver sight in 2nd picture.
The scope rail is a piccatiny type.

Image

Image

The stocks used were wide ones for REM long actions, just add recoil
block ahead of recoil inleting for the longer action, drill new screw hole
Open the stock forward to original bolt hole for longer cases and mag.

About Enfields for our case, one of my favorites, Some don't like the
sporterizing, welding bottom metal straight. Many think straightening
is a huge job needing special jigs. Easier just use one being added on for a jig
with a bolt, to weld on the straight extension, Do top weld, then cut old
extension that is under off with a thin cutting wheel, then weld bottom.
When we bolt the short piece on the one we are straightening, we grind
the short slant off so the added piece lays on there flat.
The one you cut off can be used as the top extension for the next one!!!
Just keep on building...Ed

Here is a fancy stocked 24ga FH built on a NEF, built by
a guy in Canada. Its straight back, high comb
stock, handles recoil great.Neat looking work... Ed

Image


About our 2.17" 585 BB case for lever guns, pistols, etc,.
It is made from our 585 case cut back to 2.17" long.
With loaded length of about 2.8" work in lever guns, etc.
Work in 71s, later 1886s, Henry steel frames made for 45-70.
One guy is putting one in single shot action set up with
Contender style pistol grip for testing in long rifle barrel,
to simulate pistol recoil..Be very brisk recoil in a case
that holds 110 gr powder under a light Minie bullet.
Maybe work in a Rossi Judge with heavy barrel.
Or rolling block rifles and pistols...Gonna try one in 1887.
Got first one in one of our guys Greener GP for testing..

In some ways big bore shotguns and rifles are sexy.
By looking at the shape of the fire and smoke cloud....
Thanks for picture, to the great NitroExpress Forums site.


Image

Here is picture of another neat sporterizing deal for Enfields.
On those without rear bridge pocket welded up, we just mill down
and shape it so debth of the pocket matches bottom section of
weaver rail and screw or epoxy it in. Shape to drive in hole tight.
Can use as a rear scope ring mount or mount for peep sight
like a compact UTG sight...Ed

A poster reading our threads said '' I'm slowly becoming a recoilapheliac''..
That is neat term , and very glad that folks are catching the big bore fever.

Here is a simple, yet neat peep sight we can use on the rear sporterized
bridges of Enfields, works on other rear bridges also.Including shotguns.
I like peep sights the best for most shooting. They also come with flat
bottoms also for bridges and receivers that are flat on top.

Image



Here is another pic of our guys 24ga FH in the NEF

Image


On straight sided cases like our 585 HE the die set has a mouth expander
die to make it easy to insert bullets. The die flares the mouth, but I always
felt that doing what is really a relative relatively sharp flare, and then the slight
roll crimping the same area of the case into a groove on the
bullet or slug, shortens case life.

So I just use expander plug out of the die, by hand, using just the bottom of
of the expander plug and just push it in a little, wobble it around a small
amount, bullet goes in ok, case mouths last longer, good for dozens of loads,
with moderate hunting and target loads.Only takes a few seconds and less
work that has to be done in the press ... Ed

Here is video by Corlanes Sporting, Dawson Creek, BC, CAN.
Known as Rocky Mtn Rifle. Video is on Youtube of testing our
585 HE in a barreled action, they are building for a guy. They are
shooting it into their big bullet trap with test load..

Picture of Rossi singleshot with 585 barrel mono-blocked into it,
chambered for our 585 BB 2.17" case, for testing in a light rifle
with just pistol grip to simulate the case in pistols. Others going to
put case in leverguns, autoloaders. We got lots of cases. Ed

Here is picture of a great old time 8bore double.
I like those old outside hammer, big bore guns.

Image

The style of most break actions singles aren't the greatest, that we
we used for 12ga FH, 10ga FH, other caliber barrels we mono-blocked
in them like .585" bore for 585HE and 24ga FH.. One that is close
that we have, is the Magtech.

Well the guys have found one that is super strong lockup and looks
real nice. And has the good quality look. It comes 12ga light shot barrel,
soon be monoblocked to rifled 24ga FH, the little brother of the 585HE.

Told company if they did them NEFUltra style, rifled, heavy 12ga slug barrel,
for shotgun caliber only hunters, they couldn't make them fast enough.

Image


Here is picture of 585HE, In an Enfield that Bret and Darrel in Minn
set up with great camo finish, with nice brake job. It is in a Hogue, recoil
reducing, rubber coated, Compstock.Great job they did.. Ed

Kind of a neat suppressor,

Here is folder shotgun, the guys set up as 24ga FH.
Shoots nice, looks nice, it a more expensive break action,
compared to many others.

Here is picture of a MN a guy is doing 585HE in..
It is singleshot. Redid bolt handle, mounted it on the bolt
further back, so the port could be lengthened for our long case.
Also puts handle back where it is easier to grab.
Needs, more shaping, polishing, blueing, scope rail added.

Here is a helix driver seal we made by cutting base from helix driver

wadcup, good for fullbore roundballs that are too big to go in cup.

Best one to cut off is shortest `12ga one BPI has.


Image



Here is picture of a 585HE made on a Stiller bolt action for guy in Canada.

It was made for the poster Spooksar on Africa Hunting and Accuratereloading,

by Corlanes/Rocky Mountain rifles, in Dawson Creek BC Canada, with a

Stiller action, Timney trigger. the stock is a blue/grey laminate. He imported

the barrel, cases, dies, etc.. from us, through Prophet River in Lloydminster AB.


Image



That action similar to Lawton we had and neighbor got, that won the King Of The

2 Mile shoot at Whittington, with the 375 Lethal cartridge the neighbor made,

from our 585 brass. Made it full length case,.. It is big one on the right.

He made an 18 lb gun with McMillan target stock, a huge scope, tripod..

Nice thing is we don't need BMG action.ED

Fellow big bore nut, Nathan Vale in AUS, has worked with

Bertram and got the run of full length 12ga From Hell cases done.

Drawn 12ga long cases as strong as BMG brass with unbreakable rims.

Any wanting to get some, contact Bertram at the email -----

b.bertram1@bigpond.com ......





Some more on wildcat 375 Lethal Cartridge and Mitchell Fitzpatrick's win.......

.375 Lethal Precision Arms LLC rifle shooting prototype solid 400gr Berger bullets.

Mitchell built this rifle himself using a McMillan A5 Super Mag stock, Rock Creek barrel,

Nightforce ATACR MOA scope, Phoenix Precision Bipod, and a Lethal Precision Arms

muzzle brake. Lawton Action. Lethal Precision his own gunsmith shop, will make

these target rifles for anyone into target shooting and long range hunting..


Remarkably, Mitchell nailed first- and second- shot hits at the 2477-yard target,

a full 1.4 miles away. It is windy out there, makes shooting hard with a time limit.

The prototype 400 grain Berger Bullets solid performed great, (G7 BC of 0.56 at 3000 fps).

Here is 585 HE in an Enfield, in a Choate Heavy Varmint Stock. These are super strong.

The butts of these can easily be weighted. Couple guys doing them....... Ed

Here is a picture of the 12ga FH brass case that Nathan

Vale had Bertrams make. Next to short plastic case.

Image


Here is a picture of our 585BB headstamp. Perfect lettering

for our case as it came from production line,.

Image


I like Hogue stocks, but they aren't made for singleshots.

We use singleshots for our 12ga FH and 585HE.

Here is picture of a NEF we set up for 24ga FH and we adapted

a Hogue 1300 Winchester Hogue to it. Looks a lot better, and

handles recoil easier than factory, Butt hollow, easy to add weight,

Here is picture of 585 case in the Lawton bolt, and the wildcat

375s and others made from our cases, work in bolt also. Ed

Our friend Brian from the far north went to Africa with his 24ga FH he did in
a NEF break action and got 3 nice buffs with it. Good job.


Our 585HE, 700HE and the great 12ga FH are now in the new COTW book
published in Oct, now out for sale,



We now have our target 375 HE cartridge, made by necking down our 585 HE.
The other couldn't make enough 375s, so we started our own. It has different
shoulder taper, length, neck length, improved over the other one...Got a bunch
guys doing it, most into the 2 mile shooting venues, We're making cases,
testing, reamer prints at reamer guys, we are getting guys going. King of 2 mile
shoot last year really got the interest booming for 375 necked from our case,

Here's how we size and seat 375 HE, a simple die, a 1" die, no huge dies needed
A die we can make with resize reamer from reamer guy, a regular die body,then
pass on to the next guy, one reamer can make whole bunch of dies for folks.

I do primer work separate, not in the press.That way I can clean pocket, check
flash hole,....... SO First with lock ring set, I size cases.

When coming back out of dies with case, we notice the case still well centered,
held straight, when it is down as far as the length of the 375 HE neck... IE
the sides and shoulder corner still supported tight. About .35" down.

So we put washer or another lock ring on, same thickness as neck length,
below original lock ring, screw down tight tight in press,

Dies had a 5/8 x 24 thread in top, had powder fill bushing and other stuff same thread,
reamed out from bottom to set bullet height, with ram, case,and bullet up,

After priming, loading in the powder charge, we carefully start(boat tail makes it easy)
bullet in case by hand, slide up in die, into holder, raise ram to to top, bullet seated
perfect. Die can have different thread in top as long as big enough to hold seating
bushing of some kind , that can be made from many items.

These target bullets held in by strong neck tension, no crimping needed, and notice
bullet point will get no marks or dents, fast, easy, no 380-500 buck special dies.
Bushing centering bullet on ogive is very accurate.

OVER 900 375HE cases piled behind presses getting done. About 600 on another
bench nearly ready. Small batches in shelves.And we will do more.

All 375 info, prints, specs, pictures, load data, etc, is public domain, worldwide,
for any target, hunting, etc, use..Ed

Here is picture of one of 3 buffs our guy from Canada got in

Africa with our 24ga FH he did on a NEF,


http://www.gunownerstv.com/brianbuff.jpg





Here is the neck die setup, with insert stems/plugs for the top that

are set in .020" steps to make our 375 HEs shown behind

from our 585HE cases. 900 cases behind and 600 on

another bench, mostly done, and 600 started elsewhere,

We also made a hydraulic form die, 375 HE test gun, starting with

lighter bullets, for example got 340 gr to 3700,

Will test up to 400gr We will find top speeds and powders needed

to get that, and have info where to get powders. Reamer prints are

at reamer guys, all prints and info is public domain... Ed

Picture of fellows at Vestals Gunsmithing test firing 585 HE

they built for a guy. They got 750 gr to almost 2800 from

ultra short barrel, not a full load . A regular barrel would be

over 2900, 14000 ft lbs with full load..

http://www.gunownerstv.com/585blast.jpg



Picture of our 375 HE cases, with little 378 WEA on left.

Middle case is with 330 gr, right case is 400gr bullet.

Image


Here is picture of out 375HE testgun, in heavy t-hole stock.

So far 340 gr to 3700 and 360gr 3600.

Image


Next 416 HE target case, these run through the hydro-die,

test gun done,will complete testing soon, to confirm specs.

When specs set, info will be sent to reamer guys

Soon will have 408 HE with specs set up also, for guys,

Smaller case 416s and 408s can be reamed out for

our bigger case .Ed

Here is picture of a brake on 12ga FH with real hot loaded
hollowbase lead slug, brake needed more clearance
for the expanding slug.

Image


Here is the before and after of 375 HE cases,
2 on left necked, 2 on right formed in hydro die after necking..

Image

Here is pic of 416 HSM second from left we are experimenting
with, going to see if we can make the ultimate 416 ELR case.
Can be 3.60" to 4.00" long, a long one pictured.
Holds over 280 gr ball powder under bullet. In the picture,
1st case is 416 HE, 2nd 416 HSM, 3rd 375 HE, 4th 378 WEA.

416 HSM will get 400gr to 4100 plus without needing BMG action,
470 gr 3800 plus , it may be the ultimate target, singleshot 416..
Case will work in fat bolt actions, with heavy enough barrel
to have good, milder, barrel harmonics and srtill be under 50 lbs.
A lot of the 2 mile type shoots are adopting 50lb limit.

Image

Here is picture of the 416 HSM fireformed once,
next to bmg case we make it from and as we
improve wildcatting process next few weeks
some specs may make small changes, now from
base to shoulder is 3.45", case 3.97" long. Ed..


Image


Manson has 416 HE and 408 HE prints, as well as 375 HE
He can also make you a resize die reamer from that info.
We got 700 cases in 416 and one more pass if 408s wanted, ,
Going to do lot more cases for these 2 sizes also,
Questions, PM or email. ph 989-644-5228..

Here are final specs for 416 HE.
Length 3.32", belt diameter ,655", base dia .635" ,
length base to to shoulder 2.860" , 30 deg shoulder.Ed
