Do you have a hankering to shoot Extreme Long Range (ELR)? Then you’ll want a large-caliber cartridge with plenty of boiler room. Some of the most successful ELR cartridges have been based on the CheyTac family, including the .375 CheyTac (9.5×77) and .408 CheyTac (10.36 x 77). Now brass for both these jumbo cartridges is offered by Peterson Cartridge. This Peterson Cheytac brass has proven to be tough and long-lived. And it is capable of winning — Derek Rodgers won the 2017 King of 2 Miles (K02M) event shooting a .375 Cheytac with Peterson brass. Here’s a report on how Peterson developed and tested its tough CheyTac cartridge brass.
Developing and Testing CheyTac Brass
Report by Peterson Cartridge Co.
Our president, Derek Peterson, has live-tested our most recent iteration of the .375 CheyTac (aka 9.5 X 77). He started with five casings, and did a full-body resizing after each firing. He got 17 firings out of each before he started to notice the early signs of case head separation. [Editor: Theses were with extremely high pressure loads.] He then took another set of casings and after each firing he just bumped the shoulder back, like a typical reloader would. He got 20 firings out of those casings.

Low MV Extreme Spread
On the first two shots the muzzle velocities were within 12 feet per second of each other. On the 3rd and 4th shots the muzzle velocities were within 6 feet per second of each other. By the 5th shot the muzzle velocities were within 1 foot per second of each other. Now that is how you can put two bullets in the same hole down range.
No SAAMI Spec for CheyTac Cartridges
As many of you probably already know there is no SAAMI spec on these calibers. So, without a SAAMI spec there is no stated maximum pressure for a service load. However, there IS an international spec on the .408 [promulgated by the] CIP (Commission International Permanente). And the CIP max pressure for this round is extremely high. Our partner in Europe tells us it is probably unnecessarily high. Our partner loads these rounds and they have a standard load for the .375s which is also quite high. So that is the pressure we did our testing at. To even achieve that pressure, we had to use a compressed load. We are explaining all this to say that you [should not use] a load that hot, and therefor you will most likely get more reloads than we did[.]
Peterson Brass Goes Through 11 Dimensional Tests
With all the casings we make in any caliber, we perform a battery of in-process, real-time dimensional checks. [We test] 11 different dimensions continuously throughout each shift. Some of these are tube cylindricity, mouth to body concentricity, primer pocket diameter, length to shoulder, overall length, and more. These measurements are automatically fed into Statistical Process Control software. If a dimension begins to drift from nominal we can catch it immediately and correct it.
Peterson is Fully Committed to CheyTac Brass Production
Peterson Cartridge purchased additional manufacturing equipment designed specifically to produce these large casings. Our capacity is 5-million casings a year. We are committed to there not being a shortage of these calibers ever again.
Derek Rodgers is the 2017 King of 2 Miles. He is also the first-ever human to ever hit the maximum distance target target at 3368 yards (1.91 miles) in competition. His cartridge choice? The .375 CheyTac. Derek ran Cutting Edge Bullets in Peterson brass with Hodgdon H50BMG powder.
Q: Why did you choose the .375 CheyTac cartridge?
Derek: When I was asked to join the Applied Ballistics Team, I needed to get an ELR rifle built in a short period of time. I was under a very tight time schedule to get the project complete. In an effort to eliminate variables, I decided to keep things standard and as simple as possible. I chose the .375 CheyTac for the ease of getting components. The larger rifles are more difficult to get components quickly and I felt like the .375 CheyTac had enough attributes to be competitive at ELR distances.

March Scopes (from DEON in Japan) has unveiled a remarkable new riflescope, the likes of which has never been seen before. The new Genesis ELR Scope has more elevation travel than has ever been packed into a scope before — 400 Minutes of Angle. That’s four or even five times as much as most other optics. This will allow the Genesis to get you on target, with no special external mounts, at three miles with a .416 magnum cartridge*.
For other popular cartridges/calibers, this is the range you can shoot and still have sufficient elevation travel with the Genesis. This is with the built-in elevation alone, no need for adjustable mounts, tilting rails, or prism systems:
.224 Cal to 2450 yards** | .308 Win to 2950 yards | .338 Lapua Magnum to 4000 yards
Take a good look — we bet you’ve never seen anything like this before (Big PHOTO). The new Genesis was unveiled at the IWA trade show in Germany this morning. The video below shows the Genesis being unveiled by Mr. Fumio Shimizu of Deon Optics and UK/Euro Distributor Gary Costello. Thanks to Vince Bottomley of TargetShooter.co.uk for the report from IWA.
NOTE: Click the Speaker Icon to hear audio.
How Much? Global Price for the March Genesis isn’t finalized yet, but March USA just took the first order at $5000.00 USD, without accessories. March expects to start shipping in four (4) months.
Claimed to be effective up to three miles with popular large, magnum ELR cartridges, the New Genesis sets a new benchmark in the Optics field. This won’t be cheap — posting on Facebook, a March representative said the the price is “still to be determined” but will be “approximately $5000 to $6000″. One of our Forum members just placed the first order in North America, and was told the base price (without accessories) was $5000.00 plus $50.00 shipping.
The All New March Genesis 6-60x50mm ELR Rifle Scope
The new March Genesis represents a revolution in scope technology/design — the dawn of a new era for ELR (extreme long range) shooting. The Genesis concept began in late 2016 when a group of world-class shooters asked for a scope that could be used effectively at ranges of two miles and beyond…
The chief engineers of DEON Optical Design took on the challenge and produced several prototype designs, tested extensively on three continents. Eventually DEON produced a truly ground-breaking optic — a new beginning in scope design. The Genesis ELR rifle scope offers up to 400 MOA of elevation, which will allow the shooter to shoot from 10 yards out to 3 miles*.
The unique design of the Genesis allows the shooter to always see through the central part of the lens, producing clarity, definition, and minimal chromatic aberration. This holds true even on 400 MOA! On other scopes, when the extremes of elevation are used, you won’t get the same performance — you may seen distortion and darkening. Also incorporated into Genesis is the proven DEON ‘High Master’ lens system — super ED lenses with high-refractive glass offering very high resolution and natural colour right to the edge of the image.
March Genesis 6-60x56mm Specifications:
– 400 MOA of total elevation travel with Zero-set feature (300 up, 100 down)
— 6-60X Power First Focal Plane (Highest FFP zoom ratio and magnification sold)
— 150 MOA of total windage travel (75 MOA left and right)
— 50 MOA per turn, 1/4 MOA clicks
— Wide-angle eyepiece with 25 degrees apparent field of view
— Eye relief 67-82mm and exit pupil 3.3mm at 6X to 0.93mm at 60X
— Six-step illumination module with on/off clicks
— Integral Picatinny mounting-points on the main frame.
— High Master ED lens system with 56mm objective.
— Side-Focus Parallax from 10 yards to infinity.
— FMA-MT MOA-based Reticle for ELR (MIL-based reticle coming later)
— Central gimble system and slider bearings with main frame (worldwide patents pending)
— Weight 1.5 Kg

* March says there is 3 mile range with a “.416 Cheytac”. Well, there is a recognized .416 Barrett cartridge and a .408 Cheytac. March says the .416 Cheytac is a “special wildcat … developed due to licensing needs for Norway.”
** March lists “.224 Cal”. We assume this refers to the .223 Remington cartridge, but it could be something completely different, such as a 22 Nosler, or .224 Valkyrie.

The King of 2 Miles event, and other Extreme Long Range (ELR) competitions, have spurred great interest in ultra-long-range shooting. The challenge of making the “longest shot ever” can be compelling. Some shooters have recently claimed World Records for mind-blowingly extreme distances. But you can’t have meaningful records without uniform, accepted standards. If you take 100 shots to hit a target at 3 miles, is that really a record — or just dumb luck? And if you hit the target just once after trying for hours — it that really worth bragging about?
ELR Central, an organization founded by Bryan Litz and his Applied Ballistics Team, hopes to promulgate new standards under which an ELR World Record can be established. Multiple hits will be required, with a uniform 36″x 36″ target size. No longer will shooters be able to claim a world record if they hit a barn door with a single shot. Under ELR Central’s proposed standards, in order to set a World Record, the shooter must place three consecutive rounds on a 36″ target with no sighters. As Kelly McMillan notes: “Now THAT is a record people can aspire to break.” On Facebook, one wag asked: “You mean we can’t walk in a hit with 32 sighters and claim it?” To which Kelly replied: “Though that seems pretty common — NO!”
ELR Central explains: “ELR shooting is the pinnacle of small arms precision shooting and so it’s natural that record setting is a big part of ELR shooting. Historically, world records for ‘longest shots’ have not been formally defined. As of 2017, ELR Central has published a set of guidelines and standards by which official world records can be established.”
Coming Soon: ELR Record Competition in Nevada, 1/21/2018
To help establish its new standards for ELR World Records, ELR Central will host a competitive ELR World Record Event on January 21, 2018 at the Front Sight Firearms Training Facility near Pahrump, Nevada.
Next month, ELR Central will host its first-ever ELR World Record Event. ELR shooters can showcase their skills in an organized, 3 for 3, on-the-record competition. Targets will be placed from 1500 to 2500+ yards. Shooters will have 3 shots, starting from a cold bore to attempt a World Record. This event is open to the public, and free to spectators. Registration is $50 per shooter. Contact Kathy.Barnhart [at] appliedballisticsllc.com for more information.
Big Rigs prevail in the ELR game. Here is the massive barreled action for Paul Phillips’s latest ELR rifle, which boasts a 38″-long tube.
Heavy, high-BC bullets are best for ELR competition. Derek Rodgers won the 2017 K02M Event shooting a .375 Cheytac with 400gr Cutting Edge Bullets.

What cartridge would your chose to hit targets at long range … extremely long range, as in 2500 yards? Well, for ace competitive shooter Darrell Buell, the answer is the .338 Allen Magnum, a .408 Cheytac necked down to .338. This “super-sized” cartridge flings .338-caliber, 300-grain Berger Hybrid bullets at 3450 fps. That delivers some impressive ballistics at ultra-long range. Darrell got to “test-drive” a .338 Allen Magnum rifle at 2500 yards (1.42 miles) while teaching a Long-Range Seminar at the Legion Operator Training Group (OTG) Facility in Blakely, Georgia.* The rifle belonged to Christopher Sykes.
Shown below is the 338 Allen Magnum (AM) next to a .308 Winchester round loaded to an extremely long OAL. The .338 Allen Magnum is a wildcat based off the .408 Cheytac (Cheyenne Tactical) parent case. The cartridge’s inventor, Kirby Allen, states: “The .338 Allen Magnum, when loaded with a 300gr SMK, offers a legit 500 to 600 FPS velocity advantage over the 338 Lapua Magnum”.
Darrell says: “Yeah, it’s a beast [but] with that brake, it kicks less than my .308 competition rifle. It’s got more energy at 2500 yards than a .45 ACP has at the muzzle. The .338 Allen cartridges are standing next to the SEB Joy-pod, along with a standard .338 Lapua Magnum cartridge. With the excellent muzzle brake on the .338 Allen, I could spot my own hits with just the slightest twitch of the joystick. The rifle was not particularly heavy, consequently the pod would hold the crosshairs where you left them without a hand on the joystick.”
There was a lot of buzz at the Defiance Machine booth at SHOT Show. The new Defiance actions are beautifully made, and they have already been used in some impressive custom rifle builds. Defiance, based in Columbia Falls, MT, has rolled out a line-up of four (4) custom actions: Rebel, Mutant (for tubeguns), Renegade (for .408 CheyTac), and Titan (for 50 BMG). These actions all feature beautiful machining, with Wire EDM-cut lug ways, advanced-design extractors, and a true one-piece bolt. All action materials are pre-hardened before machining to prevent changing tolerances during heat-treating. Southpaws will be happy that both right and left-hand versions of all four actions are offered.
The Rebel actions feature a Remington 700 footprint for ease of inletting and stock compatibility. Notably, the Rebel actions are available in four lengths. Buyers can choose Medium, X-Medium, Long, or X-Long lengths to accommodate all popular factory chamberings and extended-length handloads. Multiple magazine well cuts are available for all of today’s popular magazine types including hinged floorplates, DBMs, or single-shot. For a rock-solid optics installation, Defiance can supply Mil-spec Picatinny rails with various built-in MOA geometry. This stout rail is secured to the action with five pins and 1/4-28 X 1/2″ screws. Base price on a Rebel is $1270.00 (Medium) or $1300.00 (Long), with many available extra-cost options. Defiance says delivery will take at least 60 days from order date.
We were very intrigued by the Mutant action with its integrated recoil lug. Offered in Medium and Long action lengths, Defiance’s new Mutant receiver is made specifically for the Eliseo RTM and RTS Chassis Systems. The Mutant features an extended tenon length for increased barrel thread contact and bedding surface. (Extended tenon is optional on the Rebel). The Mutant’s integral recoil lug adds rigidity and simplifies tubegun assembly. Medium-action Mutants are typically built with a Guardian mag-well cut to accommodate AI and AW magazines, while Long-action Mutants fit AI single-stack magazines and can be of Badger length or the longer CIP length for extended-OAL cartridge loading. The starting price on a Mutant action is $1200.00 (before options), and delivery is at least 60 days out.
The beefy Titan (50 BMG) and Renegade (.408 CheyTac) actions look like they will become very popular with the big-caliber shooters. These jumbo actions share the advanced features of their smaller cousins, but they are sized up significantly to provide additional strength, stiffness, and bedding surface. On both big actions double-plunger ejectors are used in combination with M16 extractors for reliable case ejection. Both Titan and Renegade actions are offered either as a single-shot or repeater. The Titan is currently sold exclusively through Proof Research, while the Renegade is not yet in production. Defiance plans to build 600 Renegade actions later this year, after demand is filled for the Rebels and Mutants. The anticipated price for the Renegade is $1750.00.
OK, we suspect we’ve whet your appetite. For final pricing (with customer-ordered options) and availability call Defiance at (406) 756-2727. For specs, features, and lots more photos, visit DefianceMachine.com. Contact Proof Research, 406-756-9290, with order questions about the 50 BMG Titan action.
