A 585 HE ...shot  with moderate heavy load......
Here is a 375 HE target gun  set up, by Asteroid Precision...
Here is video of it being tested... And with a 350gr bullet about 3450-3475,
bolt opened easily with one finger...And he's  just getting started
and is checking on  better powder, Ed..

Here is recap simple setup  to get faster loads with 12ga sabots
& slugs, Example using break actions...., reaming  chamber
 in a 12ga break action to 3.5" with a 3.5"  12ga reamer, that isn't
 something needing special order, and use 3.5" plastic cases , or
get 3.5"  brass cases made. With mag shotgun primers and
our slower powder loads you can get a  quarter more speed,
which gives 50% more energy...
585 Hubel Express  video, 190ft/lbs recoil, heavy  load,  gun little light.....
Another view of  Asteroid Precision's.... 375 HE target gun,
Here is our  416 HSM we are developing next to 416 Barrett, Ed

190 ft lbs, Good Lord man, that hurts thinking about it. Lol, my little 300wsm is only 27ftlbs in my rifle. This is a great recoil chart for the different calibers and weights. I love big boomers, love the excitement and anticipation of the recoil. Lol, but 190 might be a little too exciting.

Sometimes lady luck just bends you over and calls you Sally
I came into this world with nothing, I still have most of it left.

Some people are like Slinkys. Pretty much useless but still make you smile when you push them down the stairs.

There is no right way to do something wrong.

Everyone brings joy to your life. Some when they come into it, others when they leave.

Well load down a bit and 2-3 lbs in the butt, shoots nice.


Get down to 12,000 ft lbs instead of 14,000,  Ed

Here in picture of the cases, are shown the steps in making
our 416 HSM case, from BMG brass,, Ed
We might have a company that is doing a bolt gun with an action
between BMG size and longer rifle actions used for 375 HE, 
375 Lethal, and Cheytacs.. To use for our  416 HSM without
having to do extreme rebating of the rim.
Here is picture of 620   416 hsm cases half done. Done on cnc ,
that slimmed them down, cut new rim and extractor groove. 
There are over 500 more at cnc getting done now, plus we  have
1000s more bmg cases we make them from, when needed..
This case is public domain and if anyone wants to make
them we can give the steps involved...Ed.

Holy frick id be afraid of touching off the trigger on one of those things!

Purpose should drive the Purchase......
The "one shot group". A way to save time, money and barrel life!

For big long cases our testing is showing that the 416  easier to get powders to work with,  less problems ..
Maybe building a target gun,don't have  375 barrel all ready, maybe go 416....
We got cases, 416 HE and 416 HSM, as well as 375...
CEB and others will have bullets...CEB  will be doing .416 in  450gr, 475gr, 500gr, 525gr and 550gr
Got sent 5 thick sided sample cases, same OD base as  585/375.416 cases, same belt, just .180" longer, 
 did a 416 HE, chambered extra barrel , cases stick over 50k. They have about .042" total taper,  .021" per 
side, when I necked couple to 416. That is a lot of taper , twice the taper of my 416HE...hanging up at 50k.. 
I could maybe go to 65k with these if we made taper with ..012" - .016" more taper to each side, but that is 
no way to build target cases. I'd have to crunch down case shoulder diameter. And would look like 30-30. 
And crazy part is, the case has enough brass material to thin up sides and stretch them way out to 4 or 
more inches,, They weigh 150 gr more than our 585/375/416,, but with real thick sides they actually 
hold less than our 416 HE with thin sides, that is .180" shorter...Our case does 65k ok without sticking.. 
And we can make super long 4" cases work if we had means to get them built, as we have 
15 powders slower than HBMG.Here is pic of thin and thick sided cases, sectioned for comparison.Ed..

Here is a drawing depicting the layout of  thick and thin sided cases,
like my 585/375/416 HE thin sided ones and the thick one in picture.
And my 585 case is not perfect,  as where it transitions from the
heavier corner to the side it isn't gradual, so case separates there
shortening  case life. There are others made that way including brand X.
The dotted line is what it should be............
Others have sent cases to section and look at, that are built thick sided and they 
stick also for the folks, If a longer case with about 5 sq in of side surface sticks and 
don't spring back, the coefficient of friction is about .01 then the pull needed to move
 it is 2500-3500 lbs..That is for big cases with normal amount of slant to the sides.
Here is picture of  six nyati and gibbs size cases sectioned.. the5th one is present 585 HE
and 6th is thick sided version. 1st  600  OK which essentially nyati basic case left straight, belt added
In the picture the nyati gma is one we built most of our first 585s on. Before we had factory run. 
Reworking made it in size that is my 585 HE,  but that brass had the sides of perfect thickness, 
not too thick, but thin without sharp transition my new factory 585s had, they  last forever as 585s......
 Fourth one is an older nyati case I used to make about 10 of my 585s from,had thin sides, heavy corner 
and sharp transition from the corner, tested  20 years ago, and they would separate after 4-6 hot loads
as 585s, my factory 585 with right powders, as a 585 will get  10 hot loads, and necked down to
416/375  4- 6 hot loads, right powders used, Moderate 577 equivalent,  factory 585 at least 20 loads..Ed.

Guy sent thick sided 375 case, next size base  diameter up from Nyati.He said,
'Yes I ran them in a ___________ rifle built by ____, the best I 
could get was 44000 psi, any more and they were stuck''
Big bore guys. other forums over the years related that trex/african case in 585
size, thick sided cases, stuck when they loaded them over 45k psi. 
Another just sent us,  thick sided 375, long case, same base OD as our 585 HE,
416 HE, 375 HE, and Mitch's  375 Lethal, and the thick ones stuck  over 45k psi.
Now you can fill those cases up, with ultra slow enough powder so they won't
stick, but powder is too slow for max speed. Might get a little more 
speed, with thick sides case, but case got to be  4- 4.5  inches long..
. Anyone needing a sectioned case of the ones I made the first of my 585s from,
 contact me, if they want to get a general idea of what case side thickness should
 be, in Gibbs size cases on up to about trex and 375 VM size case diameter. 
Here is pic of our 585 based case next to brand X and thick ones, both have 
same sharp, thinner, corner, where transition from heavy angled corner, to the
 side, the carbide draw rod could easily be reshaped with diamond wheel,
 just by grinding off sharp transition corner.  Then sides would be perfect.., .
Here is picture of 416 HE in a Choate target/varmint stock guy is doing,
using long action BSA U9 action.Setting in stock ready to do bedding..Ed

Here is picture of  thick 375 case sent to me, with thick sided trex  case, and our HE case,
The thick 375 case is .050" bigger OD base, but inside is no bigger than HE cases..
These thick sided 375s stuck for the guy using them, when loaded over 44,000 psi....
Got guys asking and doing it,  to do 416 HSM  case for BMG actions, so  leaving rim same,
as  the original bmg rim, so  will neck them,  fire form to the longer shoulder, like the others.  
Base a little bigger, Shoulder  same diameter,  same 30 degree slant, neck will be same..
Inside of case still has close to same shape, volumne within 3 % as ones we slimmed down more.
Some want to use bmg actions and can't wait for intermediate actions, or already have bmg action.
And they are really getting interested in the complete line of 416 CEB bullets now being done
clear up to 550 gr...
So there will be 3 versions, one for actions  .750" bolt, one for  .800-.850" bolt,  
And one for bigger bmg bolts. The ones for BMG called 416 HSM2 ..
Here is   416 HSM  guy working in a Montana PH, in a heavy thumbhole target stock. Ed

Here is sectioned 585  HE case in the middle, we first  made from
another case, years ago  before we had factory run of brass and
 it had perfect thickness on the sides and inside corrner.
We could fire them many times without sides thinning..
First case is  factory run of  our 585 HE,  3rd  is case that is too 
thick of  sides and sticks at high pressures..
Pic of  our factory run cases necked down to 375 and fired 4 times
at high pressure on the right,  with unfired case on the left. 
Our case is not perfect but does work...Ed

About 416 cal bullets............
The heaviest 550 gr for Extreme ELR probably  be best 8 to 1  twist , in 416 caliber bullet,
and 520 gr 9.5 to 1, and 470gr 10 to one, Some barrels I picked up are  10 to 1.......
Now a novel idea is to lighten rear of bullet with small shallow hole drilled in base, might do better
long range.which would allow 10 to one barrel stabilize the heavier 550 gr bullets for ELR.
Making bullet nose heavier makes it more stable in flight, needing less spin,
like our hollow base 585 cal minie bullets only need 48 to 1 twist, or less
while out regular 585 bullets need about 24 to 1 to stabilise them..............
The winner of the King Of 2 Mile shoot last week was using 416 Barrett with a 1 to 10
twist, with a 500 gr CEB Lazer bullet, ...Robert Brantley, with Manners Stocks....
Paul Philips was third with a 416...
GOOD NEWS-- There is now an importer and seller of our 585 HE brass getting set up here,
 in US, hopefully will be in stock, few weeks........   http://bertrambrass.com .. .. Caleb Hallet..
Have got another  intermediate size action besides the Montana PH our guys working on,
to do speed testingwith. It is  big long REM style action that can take our 416 HSM, ED
