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 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
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.
 Part 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.

In 2015, IMR® Powder introduced a new line of powders with Enduron® Technology. These powders are designed to address several performance gaps as powder technology has advanced. Here are key features of the Enduron line of propellants:
- Enduron powders contain an additive that drastically reduces copper fouling in the gun barrel. Copper fouling should be minimal, allowing shooters to spend more time shooting and less time cleaning a rifle to retain accuracy.
- The new Enduron line is insensitive to temperature changes. Whether a rifle is sighted in during the heat of summer, hunted in a November snowstorm or hunting multiple locations with drastic temperature swings, point of impact with ammunition loaded with Enduron technology will be very consistent.
- Enduron powders provide optimal load density, assisting in maintaining low standard deviations in velocity and pressure, a key feature for top accuracy.
- Enduron technology is environmentally friendly, crafted using raw materials that are not harmful to the environment.
New IMR 4955 for Larger Cartridges
For 2016, IMR has introduced IMR 4955, a new Enduron extruded powder that is a top performer with popular cartridges such as 270 Winchester, 25-06 Remington, 280 Remington, 300 Winchester Magnum and many more. This new powder falls directly between the new IMR 4451 and IMR 7977 in burn speed, providing excellent performance for most big-game cartridges. Like all Enduron Technology powders, IMR 4955 is temperature insensitive, as shown below.
Adding this propellant to the Enduron line filled in an important place on reloading benches. IMR 4955, plus the original three Enduron powders, provide excellent loading solutions for cartridges from 223 Remington to the massive 500 Nitro Express Magnum. Further, in these days of powder shortages, these new Enduron powders can fill a gap by providing comparable performance to select Hodgdon® powders. Specifically, IMR 4955 is a great choice for cartridges that work well with Hodgdon H4831.
IMR Enduron 4955 is available in one-pound (1 lb.) and eight-pound (8 lb.) containers from quality reloading retailers.

Leupold now offers easy online ordering for custom riflescope dials for your elevation turrets. A custom CDS dial lets you simply “dial the yardage” to have the correct elevation at distances near to far. For example, as shown below, if your target is at 550 yards, you simply dial 5.5 on the turret index. This is possible because the dial has been customized with the particular ballistics of your rifle and your load.
“Leupold engineers do all the hard work in the lab, making sure it’s easy and fast in the field,” said Rob Morrison, Leupold’s global marketing VP. “All the shooter has to do is provide us with ballistic information. From this simple data, a custom-calibrated dial is laser engraved for that specific load.”
Order Multiple Dials for Different Bullet Types
Leupolds’ custom CDS dials are tailored to the exact load used. With the ability to quickly change dials, it’s easy to set up several loads in a single rifle with a single riflescope. Transition from coyote loads to big game cartridges with a simple change of the dial. Or you can get different dials for different cartridges if you move your optic from one rifle to another. To order a CDS dial, call 1-800-LEUPOLD or visit Customshop.leupold.com/custom-dials and click on the appropriate dial for your riflescope.

Here’s a new tactical-style rifle you should consider if you are involved in the Tactical/Practical shooting disciplines. It features a modern, adjustable Archangel stock with the smooth, made-in-Japan Howa 1500 action, outfitted with a detachable 10-round box magazine.
Legacy Sports, distributor for Howa rifles, is offering the new Howa Archangel Rifle in .223 Remington and .308 Winchester. The ambidextrous, carbon-reinforced polymer stock features a click-adjustable cheek-riser, adjustable length-of-pull, grip storage compartment, plus front/rear quick-detach flush cups. There is also a clevet, integrated, push-button bipod attachment system. The Howa actions mate precisely into the stock and ride on aluminum pillars.
In .223 Rem or .308 Win, the complete rifle, with either 20″ or 24″ barrel, starts at $915.00 MSRP, including 10-round mag. We expect the actual street price to be around $800.00. That makes this a more affordable alternative to the Ruger Precision Rifle, which is commanding $1200.00+ these days (if you can find one). Note: Archangel Mfg. offers this Howa 1500-compatible stock in Black, OD Green, and Desert Tan, but it appears that the initial Legacy Sports complete rifle will be in black only. These rifles are fitted with the very good HACT adjustable two-stage trigger and 3-position safety. The Howa Archangel rifle is also available (for about $230 more) in a scoped package with a 4-16x50mm Nikko Sterling Scope (see below). For more information call Legacy Sports at 1-800-553-4229 or visit LegacySports.com.
Note: If you already own a rifle with a Howa 1500 barreled action, you can purchase the Archangel AA1500 stock separately (MSRP $355.99) from Arizona-based Archangel Manufacturing. This company also offers similar stocks for Rem 700, Springfield M1A, and K98 Mauser barreled actions, starting at just $202.99 for the Mauser variant.

In case you haven’t heard, Sierra has a great new 7mm match bullet, the 183 grain MatchKing (item #1983). This bullet boasts an impressive 0.707 G1 Ballistic Coefficient (BC) at 2300+ fps. These bullets also have very consistent bullet-to-bullet BC, thanks to the tips being “pointed” at the factory. Sierra explains: “A final meplat-reducing operation (pointing) provides an increased ballistic coefficient for optimal wind resistance and velocity retention.” Top F-Open shooters have told us that these bullets shoot exceptionally well, with minimal vertical dispersion at 1000. “Holding waterline” at long range is a reliable indicator that the BC is very uniform from bullet to bullet.
The design of this bullet represents a radical departure for Sierra. The 7mm 183gr MK employs a new bullet shape with a special geometry: “To ensure precise bullet-to-bore alignment, a unique bearing surface to ogive junction uses the same 1.5 degree angle commonly found in match rifle chamber throats.” Mark Walker, Sierra Product Manager, explains: “We thought instead of using the typical ogive radius that can allow slight misalignment, why not use the same straight angle that is used in the chamber leade on the bullet ogive to force itself to always align with the bore? Once past that area, we use a traditional high caliber ogive radius[.]”.
Insight Into Sierra’s New 7mm MatchKing®
by Sierra Product Development Manager Mark Walker
In late 2015, Sierra introduced a new 7mm MatchKing® bullet with a different type of ogive. As part of the introduction, I had the opportunity to use them at the F-Class Nationals held in Phoenix with very good results. While at the match, several people had questions about what exactly was different about the ogive on this bullet as opposed to our tried and true blended tangent ogive. So with that in mind, hopefully this blog will answer those questions.
In the past, Sierra has typically used a tangent radius ogive design on our MatchKing® bullets. This is one of the most forgiving ogive designs due to its ability to shoot extremely accurately when jumped, as well as, jammed into the rifling. On rare occasions, some of our MatchKing® bullets have used a secant ogive due to design constraints. However, this ogive is much more sensitive to changes in seating depth than the tangent ogive so we tend to shy away from it. When we decided to work on this new bullet, we wanted to see if we could improve on the accuracy of even our best shooting tangent ogive bullets.
One of the main factors of what makes an accurate shooting bullet is how it aligns itself with the bore when fired. If a bullet is slightly crooked when entering the bore, it will cause inaccuracy on the target. We set out trying to think of ways to make sure that the bullet has no choice but to align itself with the bore perfectly.
The first part of the barrel to encounter the bullet is the leade in the chamber. The leade is an angle that is cut into the leading edge of the rifling which helps to guide the bullet into the bore. To illustrate how current bullets fit into the leade, picture a cone (leade) with a ball (bullet) sitting inside it. The ball can be rotated in all directions and the cone cannot force the ball to orientate itself in any particular direction. When a bullet with a radius encounters the leade, it behaves in a similar way. Now this of course is a very simple example and of course advanced shooters use tight necks and brass that is perfectly formed to the chamber to make sure the bullet is aligned as perfect as possible. However, there is always a small element of misalignment that is possible even with all this precise preparation.
This brings us to the ogive on the new 7mm MatchKing®. We thought instead of using the typical ogive radius that can allow slight misalignment, why not use the same straight angle that is used in the chamber leade on the bullet ogive to force itself to always align with the bore? Imagine the same cone as above (leade) with an identical cone (bullet) sitting inside of it. The cone inside has no choice but to align itself perfectly with the cone that it is sitting in every time. With that in mind, we designed the area of the bullet which contacts the leade in front of the bearing surface using a straight 1 1/2 degree angle instead of the typical radius. Once past that area, we use a traditional high caliber ogive radius to provide a very sleek, high BC bullet.
I hope that explains our thought process behind this new bullet. In our testing, it is one of the most forgiving high-BC bullets we have ever made.

Bart Sauter of Barts Custom Bullets has acquired a LabRadar chronograph. He was curious to see how his loads performed in actual match conditions, so he brought his LabRadar to a match and set it up right on his benchtop. What he learned was quite surprising. For one thing, Bart found that tuning for the best accuracy (in the conditions), was NOT simply a matter of maintaining velocity. Read all about Bart’s experience in this AccurateShooter Forum Thread.
LabRadar Report by Bart Sauter
Bart posted: “I shot a short range NBRSA match [in March] with the LabRadar on the bench! The benches were quite close, but the LabRadar was able to pick up my shots even with the other guns going off very close to it. This is a pretty impressive piece of gear.”
It’s great for tuning. I can’t say for sure but what I saw with the PPC is that just maintaining a certain velocity will not keep the gun in tune.”
One Forum member asked: “Was the LabRadar able to pick up shots that far back (behind the muzzle) and to the side? What setting did you have it set at?”
Bart’s LabRadar unit had no trouble picking up shots when set on the bench, a bit behind the muzzle. In fact, Bart noted: “Yes it can go a long way back. At home I could get back up to around 8 feet and pick up the bullet. It’s more sensitive about the side distance. I had mine on level 4. You can be a lot farther behind the muzzle then advertised. You can also point it at your buddy’s target and get his velocity.”
Bart set his LabRadar to be triggered by the shot: “I had a tuner on the gun but no muzzle brake. [The Chrono] was set to be triggered by the sound of the gun. When you move back you have to play with the trigger level. I put mine on a tripod and was able to pick up projectiles 8 feet back, but from the side had to be within 18 inches.”
 Long-Life Battery Power
Powering the LabRadar at the range is not a problem. Bart used a portable battery pack that can power the LabRadar for a long time: “I bought a RavPower battery pack from Amazon.com. It was the most powerful compact cell phone charger they had and [it costs about $30.00]. It was able to run the LabRadar for two full days without recharging and still had juice.”
The LabRadar is a pretty expensive piece of kit, but there’s nothing else like it on the market. Bart notes: “The LabRadar itself is about $560.00. The stand is $29.95 for the bench mount and the padded carry case is $39.95. So you’re around $630.00 plus shipping.”

Have you ever left your plugs or muffs at home when you took a trip to the range? That’s happened to most of us. That won’t be a problem now, so long as you have your eye protection. Browning now offers ANSI-rated safety eyewear that includes corded NRR 25 earplugs stored in the frames. That’s a clever design — one less thing to worry about.
Browning’s new Sound Shield shooting glasses feature ear plugs stored on a retractable cord in the end of the frames. Now, if you have your shooting glasses with you, you will always have hearing protection as well. The end of each sidepiece opens to release the corded retractable ear plug. The ear plugs have a NRR of 25 dB and are replaceable and washable.
Sound Shield shooting glasses feature polycarbonate, wrap-around lenses with a frameless design to provide additional coverage and eliminate blind spots. The glasses are available in two different styles (Large/Medium) with either yellow or lightly-tinted indoor/outdoor lenses. All lens types exceed ANSI Z87.1 impact standards. A soft rubber standoff nosepiece reduces slipping and lens fogging. According to the Browning website, these Sound Shield glasses may be offered in a kit that includes NRR 27 ear muffs, but we don’t know if that is available yet.
