The guy put it in heavy thumbhole stock, thick pad,

no worse than shooting 12ga magnum goose loads

in a  8 lb  shotgun. Ed

There are guys on Castboolits forum experimenting with
locking on plastic bases securely on slugs.
Making their own front heavy ones for smoothbores.

Here is picture of our 585BB case next to long 585HE.




Here  is another view of  the great camo job on the
585HE Enfield,  a top view.  Ed

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.


 



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.


 



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

[hubel458]

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

Vale had Bertrams make. Next to short plastic case.




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

for our case as it came from production line,.




 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

[hubel458]

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

Congratulations!

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

Africa with  our 24ga FH he did on a NEF,  in 2nd picture








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

[gitano]

Wow.

[Jorge in Oz]

Nice Buff

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..





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

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




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

So far 340 gr to 3700 and 360gr 3600.




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

[hubel458]

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




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



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.



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..





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

I like the looks of that 416 HE, but don't think I would like shooting it.

Guys asking about strong economical bolt gun to use for  28ga and
410 ga and  32ga with brass cases and higher pressures than plastic cases.
They can use a MN bolt action, here is pic of one with
our 585 case in the action.Guys can get  Magtech brass cases or have
 RMC make them....Guys can make 32ga case from 500 NE,
410s from 9.3 x 74 brass, etc..



Here is picture of our 416 HSM case sectioned next to original
BMG case on the right sectioned, to show that we still have
enough thickness in the sides to handle  high pressure,
in a case with 310 gr capacity..We are getting the wildcatting
work set up so we can do at least hundred a month.
We have lots of 585s,  375HEs,  416 HEs,  408 HEs.....
And working toward getting 416 HSMs in big numbers.



Here's comparison of  416 target cases, 1st  416 HE,  have whole bunch.
Second is model of what I'd have made  on  medium machine, if I could,  
the 416 HE Long. It has capacity of  230gr..
Third is our 416 HSM which we are working on making by wildcatting bmg
cases, And if  had run long cases, make longer 375 HE necking down 416 ..




Bryan Litz just recently shot 3 shot group at 2 miles using Paul
 Phillips heavy barreled, target rifle built by Lethal Precision in  
375 Lethal Mag(585HE necked down, very  similiar to 375HE )...
 It grouped 17.5 inches tall by 22 inches wide.

Applied Ballistics shooter Mitch Fitzpatrick just hit 3 of 5 at 3520 yards,
 weekend 10-13th  at Valdina Ranch , west of San Antonio.
Also used the 375 LM case similar to our 375 HE
Great shooting at the 2017 World's Longest Shot Challenge. Ed
