Applied Ballistics has just launched a great, new online resource for shooters: The Science of Accuracy Academy. This subscription-based website is launching with nearly 30 podcast episodes, with many more planned, as well as video content, Zoom classes, and much more.
The main goal of this new online resource is to adapt and modernize the delivery of content coming from Applied Ballistics LLC. In past years, books, DVDs, and seminars were the primary avenues for delivering information. Modern technology has evolved, and the delivery of information can be done in more efficient ways such as streaming videos, podcast discussions of book and seminar content. In addition to being a more modern delivery platform, The Science of Accuracy Academy allows for more frequent updates than traditional books and DVDs.
Bryan Litz, owner of Applied Ballistics LLC tells us: “I’m very excited about this avenue to share what we’re learning in the Applied Ballistics lab. I think many shooters will benefit from the podcasts, which contain very insightful discussions and can be enjoyed in your car, or as you work. We look forward to publishing more of our research thru the Science of Accuracy Academy”.
About the Science of Accuracy Academy Content and Programs
Below, Bryan Litz comments about the Academy’s new podcast offerings and other interactive content. Bryan notes: “We’ve benefited a great deal from practicing the scientific method, and we want to share what we’ve learned.”
Book Content via Podcasts — Many of the podcast episodes are specific reviews of Applied Ballistics book chapters. I’ll sit with Mitch or Francis (both experienced, champion shooters) and discuss the chapter, what it was like to do the tests. We will also discuss behind the scenes problems, as well as what we’ve learned since publishing the books. This lets subscribers get knowledge from the books. And, as a podcast, you can listen while driving, working out, or whatever.
The World of Doppler Radar — In recent years we have spent considerable time visiting shooting matches with the AB Mobile Lab and running Doppler radar. Between that and some of the government contracting work, we’ve built up a lot of experiences and it’s been a long time since a book was published. This Academy is a great outlet for us to update the shooting world on what we’ve been doing and learning.
Ballistics Science and Precision Loading — We’ve been doing hardcore ballistic science for the past few years and have a lot to share. We’ve come to see some aspects of handloading and shooting in a fundamentally different way. For example, understanding the statistical nature of precision has caused us to re-shape how we make decisions in the handloading process. As a result, we now better understand cause-effect relationships and can make deliberate, reliable progress as a result.
Bryan Litz Announces the New Science of Accuracy Academy
The Lighter Side — Bryan told AccurateShooter.com: “Some of the podcast episodes are much less serious! We have fun arguing about which shooting disciplines are harder. For example, Mitch Fitzpatrick and I talk with Francis Colon and Chad Heckler about PRS vs. ELR shooting. We discuss what we like and dislike about the different sports, what we would like to see changed, and what competition shooting has meant for us as individuals. This open-ended format explores long range shooting from the technical to the personal and everything in-between.”
At the request of our readers, we provide select “Deals of the Week”. Every Sunday afternoon or Monday morning we offer our Best Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, optics, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.

Loading at the range remains important in the Benchrest for Group discipline. In a Special Report below, past IBS President Jeff Stover explains how loading methods (and hardware) have evolved over the years. The advent of accurate, affordable electronic powder dispensers, such as the RCBS ChargeMaster and Frankford’s new Intellidropper, have changed the game and made it easier to load efficiently at the range. And quality manual powder measures are fast and can be very consistent, with a little practice. Loading at the range permits competitors to tune their load to the conditions, change seating depths, or even choose different bullets to suit the barrel’s preferences on any given day.
Although pre-loading is not uncommon, most 100/200-yard group shooters usually load at the match, often between relays. The goal is to shoot smaller groups by staying “in tune”. In a game where 5-shot groups “in the 1s and Zeros” is the goal, tuning loads for the conditions helps deliver match-winning accuracy. Nearly all competitors in this short-range discipline shoot the 6mm PPC cartridge, or a PPC variant.
Loading at the Range — Then and Now
In benchrest shooting for group, loading at the range has been de rigueur for decades. In the Score discipline, preloading is usually the custom. The main reason is that, in Score competition, only one Aggregate (warm-up match and five record targets) per day is usually shot. That would be less than 50 shots, assuming a few sighter shots. Also, the 30BR, the dominant Benchrest-for-Score cartridge, is very amenable to pre-loading.
By contrast, the Group discipline includes 21 targets (two warm-ups and twenty record targets) over a weekend, usually shot with 6PPC-chambered rifles. Many times, the 6PPC shooters may tweak their loads through the day given changing atmospheric conditions or simply trying to find the correct tune to “dot up”. This term, “Dot up”, means the shots are essentially going through the same hole, or closely so.
Loading at the range was a bit different when benchrest competition was in its infancy. The 1951 book, Modern Accuracy by Bob Wallack, is the best of the early benchrest books. Copies can be found, from time to time, on eBay or Alibris. It is a fascinating survey of benchrest as it existed more than six decades ago. There’s even coverage of a controversial target that was argued over at the time. In it, there is a photo of Wallack using the rear bumper of a car at the bench to clamp his reloading tools. Things have come a long way compared to the range loading set-ups of modern shooters. Here you can see Bob Wallack way back in 1950:
Modern loading bench set-ups shown in this Special Report belong to top shooters Howie Levy, Bob Hamister, and Kent Harshman.
The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).
All Vihtavuori reloading powders are of the cylindrical, single-perforated extruded stick type. The differences in burning rate between the powders depend on the size of the grain, the wall thickness of the cylinder, the surface coating and the composition. Cylindrical extruded powders can also have multi-perforated grains. The most common types are the 7- and 19-perforated varieties. A multi-perforated powder grain is naturally of a much larger size than one with a single perforation, and is typically used for large caliber ammunition.
Other types of powder grain shapes include sphere or ball, and flake. The ball grains are typically used in automatic firearms but also in rifles and handguns. The ball grain is less costly to produce, as it is not pressed into shape like cylindrical grains. Flake shaped grains are typically used in shotgun loadings.
Web thickness in gunpowder terminology means the minimum distance that the combustion zones can travel within the powder grain without encountering each other. In spherical powders, this distance is the diameter of the “ball”; in flake powder it is the thickness of the flake; and in multi-perforated extruded powders it is the minimum distance (i.e. wall thickness) between the perforations.
The burning rate of powder composed of grains without any perforations or surface treatment is related to the surface area of the grain available for burning at any given pressure level. The change in the surface area that is burning during combustion is described by a so-called form function. If the surface area increases, the form function does likewise and its behavior is termed progressive. If the form function decreases, its behavior is said to be degressive. If the flame area remains constant throughout the combustion process, we describe it as “neutral” behavior.
The cylindrical, perforated powders are progressive; the burning rate increases as the surface area increases, and the pressure builds up slower, increasing until it reaches its peak and then collapses. Flake and ball grains are degressive; the total powder surface area and pressure are at their peak at ignition, decreasing as the combustion progresses.
So how does the shape affect pressure and muzzle velocity? In general, it can be said that powder that burns progressively achieves a desired muzzle velocity at lower maximum pressure than a powder that burns neutrally, not to mention a degressive powder. As grain size increases, the maximum pressure moves towards the muzzle, also increasing muzzle blast. Muzzle velocity and pressure can be adjusted by means of the amount of powder or loading density, i.e. the relationship between the powder mass and the volume available to it. As the loading density increases, maximum pressure grows.
With the high cost and reduced availability of factory ammo, more shooters are loading their own ammo. When good 9mm pistol ammo was $10/box, it might be hard to justify handloading. Now that 50 rounds of factory 9mm can run $25 or more it certainly makes sense to reload. The same is true with rifle ammo if you shoot large quantities, or if you simply can’t find your preferred ammo for sale these days.
To increase productivity when reloading large quantities of ammunition, many shooters are thinking of getting a progressive press. Because multiple operations take place with a single pull of a lever, a progressive press can produce way more ammo in a given period of time than any single stage press. With a progressive, on the ram up-stroke, the multiple stations can simultaneously remove spent primer, full-length size case, drop powder, seat bullet, and crimp (if desired). Most progressives are also set up to prime cases with the ram in the lower position — though some guys prefer to prime manually.
Progressive presses aren’t just for high-output pistol ammo or bulk rifle ammunition. Good progressives can be adapted to do certain reloading tasks for top-on-the line match ammo. You might use a progressive for decapping, priming, and sizing, then throw powder and/or seat bullets separately. Some Champion shooters do use progressives to load their match ammo! For example 5-Time National Long Range Champion John Whidden and 2020 Berger SWN F-Open Champion Jay Christopherson both use progessive presses for some (but not all) operations.
To help you get started with progressive presses, here are six videos from UltimateReloader.com that cover seven popular machines, from the elite Mark 7 Evolution to the affordable Lee Loadmaster. With many of these machines you can add separate vertical bullet feeder systems that further increase loading efficiency. Machines Covered: Lyman Mark 7, Dillon XL-650, Dillon XL-750, Dillon RL-550c, RCBS Pro Chucker 7, Hornady Lock-N-Load AP, and Lee Load Master.

SAFETY BONUS — Why You Need a Lock-Out Die
The RCBS Lock-Out Die can also be used with some Dillon and Hornady progressive presses.
If you load pistol or rifle ammo with a progressive press, we strongly recommend you get a Lock-Out Die from RCBS. This unique reloading die will prevent your progressive press from advancing if the dispensed powder charge is more or less than about 0.3 grains too high or too low. The Lock-Out Die really works.
The Lock-Out Die works by using a central die detection rod that sets its vertical position based on the height of the powder column in the case. Through an ingenious design, if the powder column height is too low or too high, the rod locks in place as you start to pull the press handle. This halts the press before the ram can lift and the cartridge plate can advance. Unlike a beeping alarm system (which can be ignored or defeated), the Lock-Out Die physically stops the movement of the press ram and prevents a bullet being seated in the “problem” case.
It takes a bit of tweaking to get the Lock-Out Die detection rod setting just right, but once it is correctly positioned, the Lock-Out Die works smoothly in the background. The Lock-Out Die won’t interfere with the loading process unless it detects a high or low charge — and then it positively stops the progressive loading cycle.
While crafted for use in RCBS progressive presses, the RCBS Lock-Out Die can also be used on a Dillon XL Progressive or Hornady Lock-N-Load progressive — though it does take up one station which could otherwise be used for a final crimp die (after the seating die). This Editor has used the RCBS Lock-out die very successfully on an RCBS 2000 progressive press for many years.
News from New Zealand — AMP to Ship 10,000th Annealing Machine Annealing Made Perfect (AMP) can celebrate a real milestone. After shipping its very first induction annealer six years ago in February 2016, Annealing machine number #10,000 will leave the New Zealand factory next week. In that time, the AMP annealer has progressed from the original part-analogue Mark I through to today’s smart, fully digital Mark II annealer. Over the six years of production, over 55,000 annealing pilots have also shipped. Company president Alex Findlay says “AMP annealers are now standard equipment in many ballistics laboratories. We are proud that our annealer is considered mandatory on the reloading bench of precision marksmen worldwide. We export to every sports-shooting country. Our patented AZTEC system means that even a novice reloader can anneal with the same precision as a world champion.”
How the Computer-Controlled AMP Induction Annealing Machine Is Crafted
New Book about Annealing Made Perfect’s Business Development
To mark the occasion, AMP has released “Making Perfect”, a 320-page full-color book which chronicles the company’s growth from first concept in 2012, through the years of R&D, right up to today’s market-leading products, including the ground-breaking AMP Press diagnostic bullet seating instrument. This excellent book includes the full “Annealing Under the Microscope” series of research articles, which are fascinating reads for any AMP owner, or potential buyer.
In the process, Alex and Matt have worked with many of the leading figures of the shooting world. This fascinating book explains how two guys in New Zealand created a unique new product, and who helped them along the way. Alex send AccurateShooter a copy of this book recently, and we can affirm it is a well-written, interesting guide to the creation of the AMP annealer, and its remarkable technology. There are plenty of color photos that show, from start to finish, how the AMP machine was developed and perfected. AMP’s new Making Perfect Book is available on the AMP USA webstore with shipping from Las Vegas. It is also sold through AMP’s international webstore with shipping from New Zealand.
If you want smoother bullet seating, inside neck lube can help. Forum member Ackleyman II likes to add a little Mica powder inside his case necks before seating bullets. This is easily done with the Forster three-brush neck lube kit. Ackleyman tells us: “Many loads that I have will not shoot well with a dry neck compared to a neck that is cleaned and lubed with this [Forster Dry Lubricator] — the best $15 you have ever spent.”
The Forster Case Neck Lubricator features three brushes attached to a tough, impact-resistant case with holes for bench mounting. The brushes accommodate all calibers from 22 to 35 caliber. The kit includes enough “motor mica” to process 2000 to 3000 cases and has a cover to keep dust and grit from contaminating the mica. By moving the case neck up and down on the correct mica-covered brush, the neck can be cleaned and lubricated at the same time.
Function: Lubricate case necks for easier resizing
Contents: Kit with base, lid, and three nylon brushes
Lubricant: Includes 1/10 oz. of Motor Mica, enough to process 2000-3000 cases
Neck Lubrication After Ultrasonic Cleaning or Wet Tumbling with Pins
If you wet-tumble your cases with stainless media and solvents or ultrasonically clean your brass, you may find that the inside of the case necks get too “squeaky clean”. The inside surface of the neck looses lubricity. In this situation, applying a dry lube can definitely be beneficial. CLICK HERE to see story about ultrasonic cleaning.
This past Friday was April Fool’s Day, and there were some clever spoofs. One notable April First item came from Vihtavuori, maker of premium propellants. On April 1st, Vihtavuori (VV) announced a new men’s cologne — a “New scent for the avid reloader: Vihtavuori Eau de Gunpowder.”
Here is the product description:
“Our composition opens with an aromatic smokiness and lingers on the dark, addictive scent of graphite and nitrocellulose. A powerful and refined composition for the serious reloader who wants to feel connected to his powder every day. Try the essence of accuracy with Vihtavuori Eau de Gunpowder — you won’t be disappointed.”
Comments from Readers:
One Facebook poster observed: “I love the smell of gunpowder in the morning…” *
While another FB fan joked cleverly, “Will it be available in different burning rates?”
Finally, one astute poster said this Vihtavuori product actually has serious commercial potential: “I know today is April 1st … but I want this! It would market well I think!”
For April 2023 — Will Vihtavuori Offer a Fragrance for Females?
Recognizing that there are many very talented lady shooters in the world, we think Vihtavuori should also introduce a special scent for ladies, i.e. a Female Fragrance. Perhaps it could be called Parfume de Pistol, Fragrance de Firearms, or VV N°5.56? What do you think ladies, would such products sell?
Kirsten Weiss would be a great representative for a Ladies firearms fragrance.
* In the 1979 Hollywood movie Apocalypse Now, actor Robert Duvall famously stated “I love the smell of Napalm in the morning.”
Harrell’s Precision sells “semi-custom” full-length bushing dies for the PPC and 6BR chamberings. While the Harrell brothers do not cut the die to spec, they carry a large selection of dies made with slightly different internal dimensions. When you send in your fired brass, the Harrells choose a die from inventory with just the right amount of sizing (diameter reduction) at the top and bottom of the case. Given the quality, and precise fit, Harrell’s full-length dies cost $115.00 plus shipping. These are currently available for PPC family, 6mmBR, 6mm Dasher, and 6.5×47 Lapua. The folks at Harrells recommend checking if you have questions about die sizing: “Unless you know exactly which die you need, do not order online. We have 8 different sizes of each caliber. Please call (540)380-2683.”
Bump Measuring Collar
The Harrell brothers provide a nice bonus item with each full-length die — a neat, little shoulder bump measuring device as shown in the photo at right. Hornady sells a stand-alone tool that does the same job, but the Harrell’s bump collar is simpler and faster. To measure your shoulder bump, simply place the Harrell’s bump collar over the front of your deprimed case (before sizing) and measure the OAL with your calipers. Then size the case in your full-length die, replace the collar and repeat the measurement. You want to set your die so the shoulder moves back about .001″ to .0015″ for most applications. (With semi-auto guns you may want more shoulder bump, perhaps .003″.)
It was bound to happen sooner or later. With the price of primers rising dramatically, and supplies being extremely restricted, we are now seeing pistol and rifle primers being marketed as “precious metals”, distributed through elite jewelry stores. With highly desirable match primers selling for $350 or more (per thousand) on GunBroker and other websites, primer makers have realized that primers are an exceptionally valuable product. Modern primers, which appear like tiny gold-colored pearls, can actually be marketed successfully through jewelry outlets and precious metals vendors.
The “precious primer” marketing trend is coming from Europe, home of the world’s leading jewelry empires. Primer maker Sellier & Bellot has started this trend, announcing that its primers will be sold through elite jewelry vendors Cartier, Tiffany & Co., and Bulgari. Not to be outdone, primer maker Fiocchi intends to market its high-grade primers through Damiani, Leviev, and Harry Winston outlets.
Starting in May, Sellier & Bellot primers will be put on display next to diamonds, rubies, and gold necklaces at Cartier, Tiffany, and Bulgari stores. Primer buyers will be able to purchase standardized primers, or special edition gold-plated primers with ruby-red internal cores. Initially the primers will be offered in sets of five, priced at $250.00.
Not to be outdone, Italian primer-maker Fiocchi plans to bring out its own jewelry line of primers, which will be offered in sets of four with Gold-tone, Silver, or Nickel finishes. These will be more affordable, with the silver-plated Fiocchis available for just $20 per set of four. There will also be a special 1000-pack of silver-coated primers for customers. This 1000-count Silver Collectors Edition will retail for $2500.00.
