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 couple hundred a month.

We still have thousands of 585s, 375HEs, 416 HEs, 408 HEs,,Ed

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.

I understand that there was 2-3 times as many guys wanting to try the 2 mile shoot at Whittington than there was openings for.
So check out Tonopah, NV 2-Mile Match Aug 24 - 26, 2017
Dates are August 24 to 26 (site zeros on the 23rd)

Applied Ballistics shooter Mitch Fitzpatrick just hit 3 of 5 at 3520 yards, this weekend at Valdina Ranch , west of San Antonio.

Used the 375 LM case similar to our 375 HE
A great accomplishment at the 2017 World's Longest Shot Challenge. Ed

About 2 mile military sniper shot kill of Isis soldier in Iraq that is the latest news...

By Paul Philips, from FB...

In response to the latest amazing 2.1 mile Canadian Armed forces sniper shot in question, A lot of my friends have been asking if this is possible or not.

If there are any doubters out there?!

There will be many events in the USA where you can come watch 1-2 mile shots. Visit ELR Central, FB, for more Information. The science of accuracy and improvement of rifle components have made this possible.

Below is a photo of a 17x22 inch consecutive 3 shot group @ 2.05 miles made with my 375 Lethal Mag. Bryan Litz on the trigger and Emil Praslick on the wind.

In the other photo, these 3 impacts were made by fellow team mates Mitchell Fitzpatrick, Derek Rodgers and Bryan Litz. Emil Praslick and Paul Phillips on the wind. All three impacts were made with only 3 rounds each. So within 3 rounds for three shooters in a row we were able to make impacts on a 36 inch plate (1 moa) at 2 miles or 3613 yards.

The purpose behind our research is to help improve technology and increase our hit % at extreme ranges. This will help save lives and bring our troops home safely.

Semper - Fi !!

Picture of Paul's Gun. Mitch also holding it with him.
Mitch was last years 2 mile shoot winnerm and Mitch's shop built Paul's big gun..Ed

Shooters now are talking more; short, fat cases sticking, pockets not lasting as expected.
Trying to get best speeds the things raising pressures are bad case proportions, too fast of powders, and the debth of the bullet into the powder space, as shown in the picture below..
My 375, 416, etc testing loaded like bottom one, in longer freebore....Ed.

Anyone with Barnard P-Cheytac action, I need some info, I understand it has action dia of 1.53" and 3 lug bolt, and I need the bolt diameter

And I need a picture of the bolt face...Ed

Here is our 416 HSM we are developing next to 416 Barrett, 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...Ed
 
Here is picture of 620 416hsm 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.

For big long cases our testing is showing that the 416 easier to get powders to work with, with less problems ..

So if you got to buy new barrel, don't have 375 barrel and building new a target gun, maybe go with 416, we got cases, 416 HE and 416 HSM...

CEB and others will have bullets...
CEB will be making .408 and .416 Lazers

.408 ---- 425gr, 450gr and 475gr
.416 ------ 450gr, 475gr, 500gr, 525gr and 550gr

They will be testing around mid-February..

My bigger diameter, 34" long 416 test barrel, was 250 bucks, 1-10 twist, 1- 5/8 inch diameter, work for bullets, 425-450gr or so..;Ed..

Maybe building a target gun,don't have 375 barrel all ready, maybe go 416....

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 layoutof thick and thin sided cases, like my 585/375/416 HE thin sides ones and the thick one.
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. ..Ed

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. Ed.
 
Here is picture of six nyati and gibbs size cases sectioned..5th one is present 585 HE] and 6th is thick sided version. 1st 600 OK which essentially nyati basic case left straight, belt added

allnyati.jpg

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 ...they had thin sides and sharp transition, and then I tested these 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 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 when loaded over 44,000 psi....

Got guys asking and I'm doing it, to do my 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..

The inside of case still has close to same shape and volumne within 3 % as the ones we slimmed down. 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..Ed

There will be 3 versions OF 416 HSM, one for actions one .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.
It has a .805" diameter bolt... Ed
