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

It should work fine......I've built on the SB brace before.....what are you doing for a buffer.....? If you are running a heavy pistol buffer that is the issue.....you'll probably wind up taking the weights OUT of a standard buffer...shoot me an email I'm here to help you figure out what is up.

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.., .

Hey folks new to the AR45 platform. Put together one of Justin's AR45 lowers with a Macon Armory DI upper with a 7" barrel along with a SB Tactical PDW pistol brace.

I also picked up a New Frontier blow back upper. After reading a little more from past posts, it looks like it will not work,


I'll post up pics when I can figure it out.

General Discussion / 1911 Build Class
« Last post by DRC on March 05, 2018, 08:18:43 AM »
Deep River Customs is now hosting a 1911 custom build class at Montgomery Community College Gunsmithing School, May 13-19, 2018.

The Deep River Customs 1911 custom build course will give provide students with instruction on the theory and specific steps necessary to complete their own custom 1911 handgun. The class will consist of lecture, demonstrations, and hands-on training from a full-time professional gunsmithing instructor and professional gunsmiths.

Emphasis is placed on the design and function theory of the 1911 style handgun as a basis for a logical approach to custom pistolsmithing practices. Rather than simply memorizing a series of steps, students will be encouraged to “think their way” through problems based on a thorough understanding of the firearm.

Students perform vital operations such as fitting of the slide to frame, precision barrel fitting for utmost accuracy, modifications for reliability, trigger work, fitting of grip and thumb safeties, fitting of sights, and shooting for accuracy and reliability. Theory necessary for understanding of each of the mechanical interactions that make each of these steps possible will be stressed throughout the course.

Students will leave armed not only with a complete custom 1911 pistol, but with a greater understanding of what makes this design tick, as well as knowledge of the tools and operations necessary to produce a one of a kind masterpiece.

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.

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..
