ELR Factory Style — Savage .338 Lapua Magnum Shoots One Mile

Savage BA110 .338 Lapua magnum 1 mile

When we first ran this story a few seasons back, it proved immensely popular with our readers. In case you missed it the first time around, check out what can be done with a factory Savage 110 BA at extreme long range — 1760 yards (one mile). Shooter Mark Dalzell did a great job with the video, which features multiple camera views so you can see the shooter and the target at the same time. Enjoy!

This video by Mark Dalzell demonstrates the long-range capabilities of the Savage 110 BA chambered in .338 Lapua Magnum. Mark took his “BadAss” rig out to the southwest Nevada desert just north of Jean Dry Lakes. He placed a 2’x3′ target way, way out there — a full mile (1760 yards) away. At that range, flight time to target was 3.75 seconds! Sighting with a Nightforce 5-22x50mm NXS scope, Mark needed a few shots to get on target, but eventually made multiple hits, using 67 MOA of elevation and 2.25 MOA left windage. You can view the hits starting at 1:56 time-mark on the video. (Mark had a second camera set up closer to the target — this displays frame in frame in the video, and if you watch carefully you can see the strikes.) The ammo was HSM 250gr HPBT match with a 3.600″ COAL. The shooting was done at 8:13 in the morning, with clear conditions, very light winds. Temp was 57°, humidity 24.5, Density Altitude 3666. Video soundtrack is La Grange by ZZ Top.

Good Shooting Mark. That’s darn good for a factory rifle. You also had the elevation dialed in real close before the firing started! That shows a good knowledge of your ammo’s long-range ballistics. We also noticed how effective that muzzle brake was. Recoil looked about the same as an un-braked .308 Win.

Big Presses for Jumbo-Sized Cartridges Used in the ELR Game

Ko2m king two miles ELR .416 Barrett cheytac .50 BMG Extreme long range press

In the ELR game, particularly the King of 2 Miles (KO2M), it’s “go big or go home”. The top shooters run large-capacity cartridges that push large-caliber, ultra-high BC bullets at very high velocities. Bullets launched by cartridges such as the .416 Barrett can sustain supersonic velocities at Extreme Long Ranges — and that’s what it takes to win. The .416 Barrett can launch a 550-grain solid bullet at 3000+ FPS.

2018 and 2019 Kings of 2 Miles Loaded on RCBS Presses
So how do you load jumbo cartridges such as the .416 Barrett? It takes a big, heavy, super-strong reloading press. We’ve learned that two recent King of 2 Miles champions, Paul Phillips (2019) and Robert Brantley (2018) both loaded their KO2M ammo on RCBS AmmoMaster .50 BMG presses. Phillips loaded .416 Barrett ammo, while Brantley loaded a similar .416 MCS cartridge.

In 2018, Robert Brantley topped the field using his custom .416 MCS cartridge. Then in 2019, Paul Phillips won the K02M competition shooting a .416 Barrett, with Brantley a close second. Both Phillips and Brantley use the RCBS AmmoMaster .50 BMG single stage press kit and RCBS .416 Barrett dies to hand-load for extreme long-range. “My ammo has been much more consistent after switching to the RCBS press and dies,” remarked Phillips, who runs the Global Precision Group. Brantley said he uses RCBS products for most of his reloading needs — from the dies and AmmoMaster, to the ChargeMaster and Brass Boss. His custom .416 MCS loads launch a 550-grain bullet more than 3,100 fps.

Long Range Shooting on a Spinning Planet — The Coriolis Effect

Whittington Coriolis Effect
Photo by Dustin Ellermann at Whittington Center Range.

The Coriolis Effect comes into play with extreme long-range shots like this (2100 yards at Raton, New Mexico). The rotation of the earth actually moves the target a small distance (in space) during the long duration of the bullet’s flight.

Coriolis Effect Bryan Litz Applied BallisticsWhen you’re out at the range, the Earth seems very stable. But it is actually a big sphere zooming through space while spinning around its axis, one complete turn every 24 hours. The rotation of the earth can create problems for extreme long-range shooters. During extended bullet flight times, the rotation of the planet causes an apparent deflection of the bullet path over very long distances. This is the ballistics manifestation of the Coriolis Effect.

Bryan Litz of Applied Ballistics discusses explains the Coriolis Effect in his Ballistics Books and Seminars. Bryan notes that Coriolis is “a very subtle effect. People like to make more of it than it is because it seems mysterious.” In most common shooting situations inside 1K, Coriolis is not important. At 1000 yards, the Effect represents less than one click (for most cartridge types). Even well past 1000 yards, in windy conditions, the Coriolis Effect may well be “lost in the noise”. But in very calm conditions, when shooting at extreme ranges, Bryan says you can benefit from adjusting your ballistics solution for Coriolis.

Bryan explains: “The Coriolis Effect… has to do with the spin of the earth. You are basically shooting from one point to another on a rotating sphere, in an inertial reference frame. The consequence of that is that, if the flight time of the bullet gets significantly long, the bullet can have an apparent drift from its intended target. The amount [of apparent drift] is very small — it depends on your latitude and azimuth of fire on the planet.”

Coriolis Effect Bryan Litz Applied Ballistics

Coriolis is a very subtle effect. With typical bullet BCs and velocities, you must get to at least 1000 yards before Coriolis amounts to even one click. Accordingly, Bryan advises: “Coriolis Effect is NOT something to think about on moving targets, it is NOT something to think about in high, uncertain wind environments because there are variables that are dominating your uncertainty picture, and the Coriolis will distract you more than the correction is worth.”

“Where you could think about Coriolis, and have it be a major impact on your hit percentage, is if you are shooting at extended range, at relatively small targets, in low-wind conditions. Where you know your muzzle velocity and BC very well, [and there are] pristine conditions, that’s where you’re going to see Coriolis creep in. You’ll receive more refinement and accuracy in your ballistics solutions if you account for Coriolis on those types of shots. But in most practical long-range shooting situations, Coriolis is NOT important. What IS important is to understand is when you should think about it and when you shouldn’t, i.e. when applying it will matter and when it won’t.”

Great Book — Modern Advancements in Long Range Shooting II

Bryan Litz Applied Ballistics Modern Advancements Volume 2 II testing pre-order

This is one of the very best books ever published about Long Range shooting. Based on sophisticated testing and research, this 356-page hardcover from Applied Ballistics offers important insights you won’t find anywhere else. Modern Advancements in Long Range Shooting – Volume II, a major treatise from Bryan Litz, is chock full of information, much of it derived through sophisticated field testing. As Chief Ballistician for Berger Bullets (and a trained rocket scientist), author Bryan Litz is uniquely qualified. Bryan is also an ace sling shooter and a past F-TR National Champion. Moreover, Bryan’s company, Applied Ballistics, has been a leader in the Extreme Long Range (ELR) discipline.

AUDIO FILE: Bryan Litz Talks about Modern Advancements in Long Range Shooting, Volume 2. (Sound file loads when you click button).

Volume II of Modern Advancements in Long Range Shooting ($44.95) contains all-new content derived from research by Applied Ballistics. Author Bryan Litz along with contributing authors Nick Vitalbo and Cal Zant use the scientific method and careful testing to answer important questions faced by long range shooters. In particular, this volume explores the subject of bullet dispersion including group convergence. Advanced hand-loading subjects are covered such as: bullet pointing and trimming, powder measurement, flash hole deburring, neck tension, and fill ratio.

Each topic is explored with extensive live fire testing, and the resulting information helps to guide hand loaders in a deliberate path to success. The current bullet library of measured G1 and G7 ballistic coefficients is included as an appendix. This library currently has data on 533 bullets in common use by long range shooters.

Bryan tells us that one purpose of this book is to dispel myths and correct commonly-held misconceptions: “Modern Advancements in Long Range Shooting aims to end the misinformation which is so prevalent in long range shooting. By applying the scientific method and taking a Myth Buster approach, the state of the art is advanced….”

Bullet Dispersion and Group Convergence
Bryan Litz Applied Ballistics Modern Advancements Volume 2 II testing pre-order

Part 1 of this Volume is focused on the details of rifle bullet dispersion. Chapter 1 builds a discussion of dispersion and precision that every shooter will benefit from in terms of understanding how it impacts their particular shooting application. How many shots should you shoot in a group? What kind of 5-shot 100 yard groups correlate to average or winning precision levels in 1000 yard F-Class shooting?

Chapter 2 presents a very detailed investigation of the mysterious concept of group convergence, which is the common idea that some guns can shoot smaller (MOA) groups at longer ranges. This concept is thoroughly tested with extensive live fire, and the results answer a very important question that has baffled shooters for many generations.

Bryan Litz Applied Ballistics Modern Advancements Volume 2 II testing pre-orderPart 2 of this Volume is focused on various aspects of advanced hand-loading. Modern Advancements (Vol. II) employs live fire testing to answer the important questions that precision hand loaders are asking. What are the best ways to achieve MVs with low ES and SD? Do flash hole deburring, neck tension, primer selection, and fill ratio and powder scales sensitivity make a difference and how much? All of these questions are explored in detail with a clear explanation of test results.

One of the important chapters of Part 2 examines bullet pointing and trimming. Applied Ballistics tested 39 different bullet types from .224 through .338 caliber. Ten samples of each bullet were tested for BC in each of the following configurations: original out of the box, pointed, trimmed, pointed and trimmed. The effect on the average BC as well as the uniformity in BC was measured and tabulated, revealing what works best.

Part 3 covers a variety of general research topics. Contributing author Nick Vitalbo, a laser technology expert, tested 22 different laser rangefinders. Nick’s material on rangefinder performance is a landmark piece of work. Nick shows how shooters can determine the performance of a rangefinder under various lighting conditions, target sizes, and reflectivities.

Chapter 9 is a thorough analysis of rimfire ammunition. Ballistic Performance of Rifle Bullets, 2nd Edition presented live fire data on 95 different types of .22 rimfire ammunition, each tested in five different barrels having various lengths and twist rates. Where that book just presented the data, Chapter 9 of this book offers detailed analysis of all the test results and shows what properties of rimfire ammunition are favorable, and how the BCs, muzzle velocities and consistency of the ammo are affected by the different barrels.

Chapter 10 is a discussion of aerodynamic drag as it relates to ballistic trajectory modeling. You will learn from the ground up: what an aerodynamic drag model is, how it’s measure and used to predict trajectories. Analysis is presented which shows how the best trajectory models compare to actual measured drop in the real world.

Finally, contributing author Cal Zant of the Precision Rifle Blog presents a study of modern carbon fiber-wrapped barrels in Chapter 11. The science and technology of these modern rifle barrels is discussed, and then everything from point of impact shift to group sizes are compared for several samples of each type of barrel including standard steel barrels.

About the .375 CheyTac Cartridge

Peterson .375 Cartridge Brass Cheytac K02M

Some of the most successful ELR cartridges are based on the CheyTac family, including the .375 CheyTac (9.5×77) and .408 CheyTac (10.36 x 77). This .375 CheyTac cartridge has proven to be tough and accurate. And it is capable of winning — our friend Derek Rodgers won the 2017 King of 2 Miles (K02M) event shooting a .375 CheyTac (9.5×77).

.375 CheyTac — K02M-Winning, World-Beating Cartridge

Derek Rodgers was the 2017 King of 2 Miles. He was also the first-ever human to ever hit the maximum distance target target at 3368 yards (1.91 miles). 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.

Read the Wind Like a Pro — Smart Advice from Emil Praslick III

Berger Bullets Applied Ballistics Wind Reading Zero direction speed windy

Emil Praslick III is widely recognized as one of the greatest wind wizards on the planet — a master at identifying wind value and direction, and predicting wind cycles. As coach of the USAMU and top civilian teams, Emil has helped win many high-level championships. In the three videos we feature today, Emil, who works with Capstone Precision Group (Berger, Lapua, SK, Vihtavuori) and Team Applied Ballistics, explains how to determine wind direction and velocity using a variety of indicators. Praslick, now retired from the U.S. Army, was an 18-time National and 2-time World Champion coach with the USAMU.

Video ONE: Wind Theory Basics — Understanding “Wind Values”

In this video from UltimateReloader.com, Emil explains the basics of modern wind theory. To properly understand the effect of the wind you need to know both the velocity of the wind and its angle. The combination of those variables translates to the wind value. Emil also explains that the wind value may not be constant — it can cycle both in speed and velocity. Emil also explains some of the environmental conditions such as mirage that can reveal wind conditions.

Emil Praslick III Berger SWN Wind calling reading

Video TWO: Determining the Direction of the Wind

Key Point in Video — Find the Boil
Emil explains how to determine wind direction using optic. The method is to use spotting scope, riflescope, or binoculars to look for the “Boil” — the condition in mirage when the light waves rising straight up. The wind will generate that straight-up, vertical boil in your optics when it is blowing directly at you, or directly from your rear. To identify this, traverse your scope or optics until you see the boil running straight up. When you see that vertical boil, the direction your optic is pointing is aligned with the wind flow (either blowing towards you or from directly behind you).

Video THREE: The No Wind Zero Setting

In this second video, Emil defines the “No-Wind Zero”, and explains why competitive shooters must understand the no-wind zero and have their sights or optics set for a no-wind zero starting point before heading to a match. In order to hit your target, after determining wind speed and direction, says Emil, “you have to have your scope setting dialed to ‘no wind zero’ first.”

Coach of Champions — Emil Praslick III
SFC Emil Praslick III, (U.S. Army, retired) works with Berger Bullets and Applied Ballistics. Emil served as the Head Coach of the U.S. National Long Range Rifle Team and Head Coach of the USAMU for several years. Teams coached by Emil have won 33 Inter-Service Rifle Championships. On top of that, teams he coached set 18 National records and 2 World Records. Overall, in the role of coach, Praslick can be credited with the most team wins of any coach in U.S. Military history.

Big Boomer .50 BMG Boasts Impressive Half-MOA Accuracy

.50 BMG Richard King Texas half-MOA

A few seasons ago, Texas gunsmith Richard King built an impressive .50 BMG target rifle for a customer. Equipped with a beefy McMillan stock, this rig has delivered some very impressive accuracy. Check out that target shot during break-in. Using On Target software, we measured this 3-shot group at 0.476″ or 0.454 MOA. Not bad for a beast with VERY serious recoil. Do you think you could beat that 0.476″ with your AR15 shooting puny .223-caliber bullets?

.50 BMG Richard King Texas half-MOA
Compare the dimensions of that massive 50-Cal action to a Rem 700 action in the middle. When you’re shooting a Fifty, size matters!

On Facebook, some folks were surprised a guy could wring that kind of accuracy out of a monster .50 BMG. One wag posted: “Yikes! He will need flinch therapy after shooting that beast.”

Another Facebooker joked: “When shooting a .50 BMG you say…In your best Crocodile Dundee voice…that’s not a gun, THIS is a gun!”

Richard King responded that this customer has quite a bit of experience with jumbo-caliber rifles: “Remember this is the guy that shot a .338 Lapua in a two-day F-Class match. Recoil might actually be easier on this 50, given the fact that it has more weight and a brake.”

.50 BMG Richard King Texas half-MOA

Richard King showed us the monster 13-lb BAT action for this rifle at the 2018 Berger SWN. Honestly, the big BAT .50 BMG action was HUGE — with the bolt fully extended it was the size of your forearm (to the finger tips). Richard joked “This weighs almost as much as an F-TR rifle (before optic) all by itself”.

Richard King Berger SWN BAT action

Specialty Tools for the Big .50 BMG
Yes, the .50 BMG is one huge cartridge. Thankfully, there are some special tools for loading the jumbo-size round. Giraud Tool produces a specialty comparator for the 50-Cal cartridge. The double-ended .50 BMG comparator is quite versatile. In one orientation you can measure base-to-ogive bullet length and also measure cartridge OAL from rim to bullet ogive. When reversed, you can use the comparator to measure cartridge headspace. Priced at $33.00, Giraud 50 BMG Comparator gauge is constructed of 303 stainless and fits most any vernier, dial, or digital caliper. CLICK HERE for more info.

Dream Day for a Vintage Rifle — Iron Sights Hits at 2240 Yards

World Record Iron Sights K31 Buffalo bison Utah
World Record Iron Sights K31 Buffalo bison Utah
Magnified 8X view looking down-range at buffalo target.

Could You Hit a Steel Buffalo at 2240 Yards (1.27 miles) … with Iron Sights?

Impossible as that may seem, that’s exactly what Ernie Jimenez did some years back at the North Springs Shooting Range in Price, Utah (elevation 5,627′). Shooting a milsurp Swiss K31 rifle chambered for the 7.5×55 Swiss round, Jimenez placed four hits on a three-foot-high, bison-shaped steel target placed a staggering 2240 yards from the firing line. Not bad for a rifle which Jimenez acquired many years ago for just $99.00. Of course he did have plenty of misses along the way (and Ernie even managed to hit the plate shielding his camera).

This video is set to start half-way through, when the shooter starts making hits:

The whole process was recorded on video and posted on YouTube. The Long-Range Shooters of Utah say this is an official Guinness World Record for longest shot with iron sights. We can’t confirm that, but it still is an impressive feat. Jimenez had to compensate for a huge amount of bullet drop. His K31’s long-range military sights helped but he still had to aim well over the pink bison. To see how far that target is, watch the video at 14:30 — a camera at the firing line zooms all the way back until the bison is nothing but a tiny dot. The photo below show the target at 8X magnification, but it’s still barely visible.

Here’s the unmagnified, “naked-eye” view from the firing line. Can you see a pink buffalo at all?
World Record Iron Sights K31 Buffalo bison Utah

Bullet Dropped Over 400 Feet along its Trajectory
To roughly gauge the bullet drop, we took a 7.5x55mm Swiss load from the Hodgdon Reloading Center. With max “book” load of H4350, a 168gr Sierra HPBT has a muzzle velocity of 2524 FPS. According to JBM Ballistics, that bullet will drop over 400 feet during its flight. That’s lot of hold-over! Assuming a 100-yard zero, 59° temp, and 5,600′ altitude, JBM calculates that the drop to 2250 yards is a stunning 210.9 MOA — that’s 4969.9 inches, or 414.15 feet!

David Tubb Talks about KO2M and Extreme Long Range Shooting

David Tubb’s long-range rifles have performed well in Extreme Long Range shooting. AT the 2019 NRA Extreme Long Range Championship, David Tubb won the Heavy Gun Division. In this video, created during the King of 2 Miles (K02M) competition at the Whittington Center in New Mexico, David talks about the challenges of ELR shooting, and cartridge selection. Big, heavy, large-caliber bullets with ultra-high BCs are favored for the ELR game, but recoil and cost must also be considered.

.375 and .408 CheyTac Brass for ELR from Peterson Cartridge

Peterson .375 Cartridge Brass Cheytac K02M

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.

.375 CheyTac — K02M-Winning, World-Beating Cartridge

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.

Sunday GunDay: .416 Barrett for King of 2 Miles Competition

Derek Rodgers .416 Barrett ELR KO2M king of 2 miles Beast 2 McMillan stock Nightforce ATACR scope extreme long range New Mexico

Today we feature a big-caliber rifle used for the most prestigious Extreme Long Range (ELR) competition, the King of 2 Miles. This rifle was built for Derek Rodgers, a talented shooter with amazing credentials. An F-TR World Champion, Derek is the only shooter to have won the F-Open USA National Championship AND the F-TR USA National Championship. Derek also won the 2017 King of 2 Miles competition. Last Sunday GunDay we featured the 33XC rifle used by Clay Rhoden to capture the inaugural American King of 1 Mile competition. That story was quite popular, so this Sunday we offer an even more powerful rig, Derek’s .416 Barrett with a massive 40″ barrel.

Derek Rodgers won the King of 2 Miles competition in 2017, so he knows all about Extreme Long Range (ELR) shooting. While Derek won his 2017 KO2M title shooting the .375 CheyTac cartridge, Derek decided that something even bigger was in order. So Derek commissioned this impressive ELR rifle chambered for the jumbo .416 Barrett cartridge. This big round drives heavy Cutting Edge solid bullets from 475 to 550 grains in weight.

Here’s the Big Rig that delivers those .416-caliber projectiles. This monster rifle weighs 40+ pounds and sports a 40″ Bartlein barrel — more length for more velocity. Derek’s ELR rifle features a McMillan Beast 2 stock, BAT EX action, and Nightforce ATACR 7-35x56mm scope. Derek explained why he moved up to a bigger caliber: “I built a new rifle with the anticipation of seeing impacts easier. It was not just a larger caliber being more effective on hitting ELR targets, but rather hoping that a missed shot would have a much larger impact. Impacts beyond a mile become harder to see due to terrain and vegetation. So any added dust or splash erupting from the earth is a decisive benefit over an equally-accurate smaller caliber.” Here is Derek’s full report on his .416 Barrett rifle.

Report by Derek Rodgers
Cartridge Choice — I chose a standard .416 Barrett cartridge as it allows for bullets up to and slightly exceeding 550 grains. It really does bridge the gap between the .375 variants and a 50 BMG. There are several great solid ELR bullet options from manufactures like Cutting Edge that range from 475-550 grains. These offer a variety of extremely high BC options for barrels that have different twist rates. Most loads will utilize the slowest burn rate powders commercially available. Good options are Vihtavuori 20N29, RL50, H50BMG and other powders with a similar burn rate.

Shooting the .416 — Tamer than Expected
An initial observation is that the rifle is very controllable and feels much like a larger F-TR gun. The rifle weighs 40+ pounds, balanced and stays on target very well. The recoil is manageable and linear. This seems to give a straight rearward impulse that does not affect positioning. This allows for quick repositioning into battery and faster follow-up shots.

Rifle Details — BAT EX Action, Bartlein 40″ Barrel, McMillan Beast 2 Stock
Derek’s .416 Barrett ELR Rig features a BAT EX action with a Bix’N Andy trigger. Out front is a gigantic 40″ long, 1:9″-twist Bartlein barrel fitted with a Terminator T5 muzzle brake. The handsome McMillan Beast 2 stock combines a lower center of gravity design with a higher butt location. Given that high butt geometry, McMillan cleverly fitted the higher buttpad with a port allowing the cleaning rod to pass through (see photo below). On top is a Nightforce ATACR 7-35x56mm scope in NF rings on a +60 MOA rail, with Holland 34mm bubble level. The stock is supported by a Phoenix bipod and rests in an Edgewood bag designed for the McMillan Xit F-TR stock.

Note the extended Buttpad height. That helps with recoil in prone position. This McMillan Beast 2 stock includes a pass-through hole for the cleaning rod.

Derek Rodgers Wins 2017 Ko2M with 3368-Yard Hit
Back in 2017, Derek Rodgers won the King of 2 Miles Competition at Raton, New Mexico. Derek, shooting with Team Applied Ballistics, was the first KO2M marksman in history to hit the target at the maximum 3368-yard (1.91 mile) distance. Here’s that historic shot:

At the 2017 K02M, with his McMillan-stocked .375 CheyTac rifle, Derek shot brilliantly from the start. He was perfect — without a miss — at the first three yardages: 1543, 1722, and 1888. He had some misses at 1953 and 2667 yards, but then he out-shot all competitors at 3028 yards, going two for five. No other shooter managed a single hit at 3028 yards. Then it all came down to the big one — the last (and greatest) challenge, the target at 3368 yards (1.91 miles). Derek nailed it… and the celebrations began.

Gunsmithing by Blake Barrel and Rifle in Arizona
Derek’s rifle was built and chambered by Bryan Blake of Blake Barrel and Rifle in Phoenix, Arizona. The chambering was done with a Manson Precision reamer. Derek explains: “Bryan and his family have been in the machine shop business for several generations and have the expertise and equipment to handle larger barrel diameters associated with F-Class to ELR-type rigs. I tried to consider all angles and potential pitfalls that might occur during the building process. However, Bryan added his own touches to make the project his own. He truly created a work of art and supplied a turn-key rifle that is meticulously built from the inside out and looks as great as the tolerances it holds.”
