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.”

Are you curious about bullet stabilization? Do you understand why bullets can tumble or become unstable if the velocity gets too low or if the twist rate is inadequate. Here is an excellent video from Gunwerks that explains Bullet Stabilization.
This animated video starts by showing the design/shape differences between an older-style rifle bullet and a newer VLD-style bullet with higher BCs (Ballistic Coefficients). Generally speaking, the longer a bullet gets relative to diameter, the more RPM is required for stability. And to achieve that higher RPM you need more barrel twist and/or more RPM. The video illustrates where the Center of Gravity and the Center of Pressure are located. These are farther apart (in relative terms) for a VLD or Hybrid-style, long-nose bullet.
When the bullet is in flight there is an angle of attack. This is exaggerated in the animation for illustration purposes, but it is important to understand the the attack angle affect stability. The rotation rate (Revolutions Per Minute) is a function of bullet velocity as it leaves the muzzle and the twist rate of the barrel. Since long VLD-style bullets need more stability, the barrel twist rate needs to be higher than with shorter, fatter bullets. This is pretty much try for all calibers.
The importance of adequate barrel twist rates for bullet stabilization is further discussed in this next video featuring Bryan Litz of Applied Ballistics:
Bullet Stability and Twist Rates
In this video, Bryan Litz talks about bullet in-flight stability and how to calculate barrel twist-rate requirements for long-range bullets. Bryan explains that bullet stability (for conventional projectiles) is basically provided by the spinning of the bullet. But this spin rate is a function of BOTH the nominal twist rate of the barrel AND the velocity of the projectile. Thus, when shooting the same bullet, a very high-speed cartridge may work with a slower barrel twist rate than is required for a lower-speed (less powerful) cartridge. For match bullets, shot at ranges to 1000 yards and beyond, Bryan recommends a twist rate that offers good stability.
The United States Postal Service allows shipment of long-barreled rifles and shotguns via the U.S. Mail. However, regular citizens who do not possess an FFL are NOT allowed to mail handguns at all.* You must use UPS for handguns (or ship via an FFL). While the USPS allows rifle and shotgun mailing there ARE many rules and regulations with which long gun shippers must comply. Here are key USPS Gun Shipping Rules from the official USPS website. CLICK HERE to Read All Gun Shipping Rules.
U.S. Postal Service Rifle and Shotgun Shipping Rules
432.1 General
Mailers must comply with the Gun Control Act of 1968, all of the provisions of postal law in 18 U.S.C. 1715, and all other all federal and state regulations and local ordinances affecting the movement of firearms. The following also applies:
a. The Postal Service may require the mailer to open parcels containing firearms or air guns or give written certification that the weapon is unloaded and not concealable (see note 1).
b. Short-barreled rifles or shotguns that can be concealed on the person are nonmailable.
c. No markings of any kind that indicate the nature of the contents may be placed on the outside wrapper or container of any mailpiece containing firearms.
d. Mailable matter must be properly and securely packaged within the general packaging requirements in DMM 601.1-7.
e. Except for shipments between licensed dealers, manufacturers, or importers, all regulated firearms must be mailed using a USPS product or Extra Service that provides tracking and signature capture at delivery (see note 2).
432.3 Rifles and Shotguns
Except under 431.2, unloaded rifles and shotguns are mailable. Mailers must comply with the rules and regulations under 27 CFR, Part 478, as well as state and local laws. The mailer may be required by the USPS to establish, by opening the parcel or by written certification, that the rifle or shotgun is unloaded and not ineligible for mailing (see note 1). The following conditions also apply:
a. Subject to state, territory, or district regulations, rifles and shotguns may be mailed without restriction when intended for delivery within the same state of mailing. These items must:
1. Bear a “Return Service Requested” endorsement.
2.Be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.
b. A rifle or shotgun owned by a non-FFL may be mailed outside the owner’s state of residence by the owner to himself or herself, in care of another person in the other state where he or she intends to hunt or engage in any other lawful activity. These mailpieces must:
1. Be addressed to the owner.
2. Include the “in the care of” endorsement immediately preceding the name of the applicable temporary custodian.
3. Be opened by the rifle or shotgun owner only.
4. Be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.
d. Mailing of rifles and shotguns between licensed FFL dealers, manufacturers, or importers are not restricted. The Postal Service recommends that these items be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.
e. Except as described in 432.3a, licensed curio and relic collectors may mail firearms meeting the definition of curios or relics under 27 CFR 478.11 domestically to licensed FFL curio and relic collectors in any state. These items must be mailed using a class of mail, product, or Extra Service that provides tracking and signature capture at delivery.
f. Firearms meeting the definition of a rifle or shotgun under 431.4 which are certified by the curator of a municipal, state, or federal museum, which exhibits firearms to be curios or relics of museum interest, may be accepted for mailing without restriction when mailed between governmental museums.
g. Air guns (see 431.6) that do not fall within the definition of firearms under 431.1a are mailable. A shipment containing an air gun with a muzzle velocity of 400 or more feet per second (fps) must include an adult signature service under DMM 503.8. Mailers must additionally comply with all applicable state and local regulations.
FOUR TIPS for Safer, More Secure USPS Firearms Shipping
Here are some other helpful suggestions when shipping long guns via USPS:
1. Bring a copy of the destination FFL holder’s license to the Post Office, just in case the staff asks for confirmation.
2. Use a Shipping Mode that Requires Signature on Delivery for confirmation.
3. Ship Priority Mail for faster delivery and BUY INSURANCE to cover complete replacement value of the firearms. Some guns may be damaged, but insurance is needed to cover full gun value with a lost/stolen shipment.
4. Double tape the ends of the box, and put plenty of padding around the muzzle and buttstock INSIDE the box.
* While ordinary (non-FFL) person may never mail handguns, there are some types of handgun mail shipments allowed by manufacturers etc. to Government and U.S. Military recipients:
432.21 Authorized Persons
Subject to 432.22, handguns may be mailed by a licensed manufacturer of firearms, a licensed dealer of firearms, a licensed importer of firearms, or an authorized agent of the federal government or the government of a state, territory, or district, only when addressed to a person in one of the following categories for use in the person’s official duties, and upon filing the required affidavit or certificate:
a. Officers of the Army, Coast Guard, Air Force, Navy, Marine Corps, or Organized Reserve Corps.
b. Officers of the National Guard or militia of a state, territory, or district.
c. Officers of the United States or of a state, territory, or district, whose official duty is to serve warrants of arrest or commitment.
d. USPS employees authorized by the Chief Postal Inspector.
e. Officers and employees of enforcement agencies of the United States.
f. Watchmen engaged in guarding the property of the United States, a state, territory, or district.
g. Purchasing agent or other designated member of agencies employing officers and employees included in 432.21c through e.
432.23 Manufacturers, Dealers, and Importers
Handguns may also be mailed between licensed manufacturers of firearms, licensed dealers of firearms, and licensed importers of firearms in customary trade shipments, or for repairing or replacing parts.

Here’s something all shooters need — a smartphone App that calculates bullet-hole group sizes from your own photos. The Ballistic-X App is simple to use. Take a photo of your target, set some values (such as bullet diameter and distance to target), then use the touchscreen to place circles around each hole. The App will calculate group size (in MOA or Mils), distance to point of aim, and provide all the info in an overlay. Then click “save” to record your group for posterity!
This App works well, is relatively easy to set-up, and costs just $7.99. It is available for both Android devices and iOS (Apple) devices. There are other ways to measure group sizes from target images, such as the excellent On-Target program, which we have used for years. However On-Target requires a software installation on a Windows platform desktop or laptop. Ballistic-X is a simple, easy-to-install App with versions for both Android and iOS (Apple) Mobile devices.
The Ballistic-X App has a relatively easy-to-use interface. Of course you can choose either MOA or Milrad group values, and Inch or Metric dimensions. There are various labeling options that provide useful info for Load Development. There is even an ATZ (Adjustment To Zero) feature for adjusting your turrets.
How to Use Ballistic-X App
1. Select Photo Source — Choose Camera to take new photo or get image from Photo Library.
2. Set Reference Values — Select Bullet Diameter and enter Distance to Target.
3. Establish Scale on Image — Mark two points on target photo to set scale. For example, if the target has a 1″-square grid lines, mark two points on grid for 1″ distance.
4. Mark Point Of Aim — Put the central X on the aim point.
5. Designate Shot Locations — Place the green circles around each shot.
6. Finalize Data Display — Position Overlay, select size/color options, and export file.
Android Options — Range Buddy FREE App
Along with Ballistic-X, there is another Mobile App, Range Buddy, that also measures shot groups. Range Buddy is currently offered for Android devices only. It is FREE, but has adverts. Range Buddy isn’t bad, but users complained about the program crashing, and there are compatibility issues with newer phones. We recommend you pay $7.99 and stick with Ballistic-X.
Think you can shoot fast with a bolt gun? Bet you can’t beat these Norwegian speed-demons. In 2019, Inge Hvitås set a Mad Minute World Record, putting 39 rounds inside a 16″ circle at 200 meters, all in a single minute. At the same match, another Norwegian ace fired 48 rounds in a minute, with 38 in the bullseye. Now that’s spectacular speed and accuracy. We first ran this story in 2019 when the record was set. Wikipedia reports this is still the current record. So we believe no one has ever put more rounds on a 16″ target at 200m (with a bolt-action rifle) than Inge Hvitås. We include videos showing Inge’s amazing sequence.
Watch Inge Hvitås Set New Mad Minute World Record:

Mad Minute World Record — 39 Hits in One Minute (60 seconds)
At the Haga shooting range in Norway, spectators witnessed spectacular speed shooting in 2019. Norwegian shooter Inge Hvitås set a Mad Minute Challenge World Record with 39 hits in ONE MINUTE at 200m. The target was a 40cm (15.75″) bullseye placed at 200m (218 yards). Fellow Norwegian Jesper Nilsstua also shot brilliantly, sending 48 rounds down-range in one minute. Jesper had 38 hits, missing the record by just one. Both shooters were using iron-sighted Sauer 200 STR target rifles, which are normally chambered for the 6.5×55 cartridge. For this event, magazines are limited to 5 rounds and shooters may use slings but no bipods or other support.
Amazing Bolt-Gun Cycling Speed — 48 Rounds in One Minute
Another Norwegian ace, Jesper Nilsstua, missed the Mad Minute Challenge record (by one hit), but boy was he fast. Dennis Santiago (who has done his own Mad Minute drill), was dazzled: “This dude didn’t get the new world’s record of 39 hits in 60 seconds. He ‘only’ got 38 hits after getting off an amazing 48 shots in 60 seconds. Watch the smoothness of his shooting. It’s amazing.”
NOTE to Readers: This video is hosted by Facebook. It may be slow to load. But it is worth watching.
For the Mad Minute Challenge in Norway, a standard 200m DFS target was used, with 1 point per hit within the black area which is 40cm (15.75″, or 6.9 MOA) in diameter.
Norwegian Mad Minute Challenge — Event Rules
The organizers of the event posted: “The Mad Minute Challenge [is] a modern edition of a old military drill. This is a place for sport shooters to … share experiences on the subject of speed shooting with bolt-action rifles. The Mad Minute Challenge is all about the sport! To make a attempt for the record everyone must follow these five simple rules:”
Rapid-Fire Shooting Comparison Video
To illustrate the remarkable speed of Norwegian champion Inge Hvitås, this video shows Inge (top of frame) compared with other skilled competitors shooting the same 1-minute course of fire in Lesja, Norway.
About the Original MAD MINUTE
“Mad Minute” was a pre-World War I term used by British Army riflemen during training at the Hythe School of Musketry to describe scoring a minimum of 15 hits on a target at 300 yards within one minute using a bolt-action rifle (usually a Lee-Enfield or Lee-Metford rifle). It was not uncommon during the First World War for riflemen to greatly exceed this score. The record, set in 1914 by Sergeant Instructor Alfred Snoxall, was 38 hits.
Listed as “Practice number 22, Rapid Fire” of The Musketry Regulations, Part I, 1909, this drill required at least 15 shots on the Second Class target at 300 yards. The exercise was just one of several annual tests to classify a soldier as a sharpshooter, first or second class shooter depending on the points achieved.
Research indicates the Second Class target was a 48″ x 48″ square with 24″ inner circle and 36″ outer circle. The sight mark was a central 12″ x 12″ shape representing a soldier. ALL hits scored points (3 for center circle, 2 for outer circle, 1 for outer square). NOTE: Though some sources say the Mad Minute drill used a 12″-diameter round target, this appears to be a mistake from Ian Hogg’s book “The Encyclopedia of Weaponry”. No other source mentions a 12″ circle, which would be a mere 3.82 MOA. In reality the true drill target was a 48″ x 48″ square, roughly 15 times larger. (From No.WikiPedia.)
Shown are funnel with ultra-long drop tube (which helps get more kernels in the cases), RCBS Chargemaster (in wood box), and Hood Press (similar to Harrell’s Combo press).
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.
NRA Media offers a series of informative videos about the Science of Shooting, covering a wide range of topics, from eye dominance to long-range ballistics. These videos feature high production values, with super-slow motion segments, as well as helpful computer graphics to illustrate the principles covered.
The videos are narrated by Jessie Harrison, a top action pistol shooter (and the first women ever to achieve USPSA Grand Master status). Jessie is assisted by talented shooters such as Top Shot Season 4 Champion Chris Cheng. There are 40 videos in the Firearm Science Video Series. Here are seven good NRA science videos, with links to others below.
BULLET TRAJECTORY — Factors at Play and Zeroing Strategies
Host Jessie Harrison (formerly Jessie Duff) and Veteran Air Force Sniper and Long Range Expert George Reinas help us understand the factors behind bullet trajectory. NOTE: There are some exaggerations in the graphics in the videos, and inconsistent terminology use, but it’s still a helpful basic primer on the subject of trajectories. This popular video has over 1 million YouTube views.
Olympic Gold Medalist Jamie Gray demonstrates the four positions used by competition shooters: Prone, Standing, Sitting, and Kneeling. Helpful overlay graphics show how the human skeleton aligns in each of these positions. This video should help hunters as well as competitive position shooters. If you shoot silhouette, definitely watch this video!
INTERNAL Ballistics — Cartridge Ignition and Bullet in Barrel
What happens inside the barrel of your gun when you pull the trigger? In this edition of Firearm Science, Jessie Harrison goes over internal ballistics, which studies the combustion of propellant, the pressure developed, and the motion of the bullet along the bore of the barrel. There are some good 3D animations showing how the powder charge ignites and the bullet moves through the barrel.
CHOKE TUBES and Shot Patterns — Shotgun Science
With over 2 million YouTube views, this shotgun-centric video is the most popular of all the NRA Firearms Science series videos. Here Olympic trap shooter Corey Cogdell explains how choke tubes affect a shotgun’s shot pattern in this edition of Firearm Science. We recommend that all Shotgun hunters watch this video — it explains the effect of choke tubes very well.
ZEROING RIFLES for Long Range — Tech Tips
The process of zeroing rifles for long range is covered in this Firearm Science video featuring George Reinas, a veteran Air Force sniper. George demonstrates how to adjust his scope to compensate for bullet drop at long range. Our friend Dennis Santiago was involved in the making of this video, which was filmed at the Burbank Rifle & Revolver Club in Southern California.
CHRONOGRAPHS — Calculating the Speed of a Bullet
This video shows a conventional chronograph with front and rear light sensors. The bullet first trips the front sensor and then the rear sensor as it flies over the unit. The difference in sensor time is used to calculate bullet speed. This is not the only kind of chrono in common use today. The popular MagnetoSpeed chrono works by tracking the bullet as it passes over two magnetic sensors mounted on a bayonet-style fixture on the barrel.
The high-tech LabRadar chronograph employs Doppler Radar to measure the speed of a bullet without the need to send the round directly over sensors. No need to set up tripods down-range. Just set the unit near your rifle’s muzzle, on the side. There is also an inertial trigger accessory for LabRadars. Interestingly, this video also explains how, in the days before electric lamps, digital processors, and radar, scientists used a mechanical “Ballistic Pendulum” to calculate bullet velocity using Newtonian physics. The Ballistic Pendulum (shown at right) was first used in the mid 1700s.
EYE DOMINANCE — How to Determine Which Eye is Dominant
Host Jessie Duff and longtime shooter Krystie Messenger demonstrate how eye dominance affects aim and teach you how to determine your dominant eye in this edition of Firearm Science. There are very simple tests you can do to determine your eye dominance. This Editor is right-handed but left-eye dominant. All competitive shooters should check for eye dominance. If you are cross-dominant, you can alter your head position or put a paper patch on one frame of your shooting glasses.
Powder and primers are still very pricey but (thankfully) we are starting to see the price of factory-loaded ammunition slide down a bit. Here is a great deal for rimfire shooters. You can now get CCI .22 LR Standard Velocity 40gr Target Ammo for just $4.99 per box, with flat-rate shipping. This is good, reliable ammo for plinking, practice, and rimfire pistol work. And it will probably be good enough for NRL22 competition if the targets are not too far out.
Save $1.40 per Round or More by Training/Competing with Rimfire
The ammo price differential is why many PRS/NRL competitors are now doing more rimfire matches than centerfire matches. At $4.99 per 50-round box, this CCI ammo runs just $0.10 (ten cents) per round. Compare that to handloaded 6mm Creedmoor ammo. These days, you might pay close to $1.00 per round just for bullet, powder, and primer. And then you must figure in brass costs and barrel depreciation. A good 6mm barrel may lose its competitive edge after 1500 rounds. That means each centerfire shot could cost you $0.40 (forty cents) or more just in barrel depreciation, assuming the cost of your new chambered/fitted barrel is $600. So you see why rimfire makes sense from a budget standpoint.
Research indicates the Second Class target was a 48″ x 48″ square with 24″ inner circle and 36″ outer circle. The sight mark was a central 12″ x 12″ shape representing a soldier. ALL hits scored points (3 for center circle, 2 for outer circle, 1 for outer square). NOTE: Though some sources say the Mad Minute drill used a 12″-diameter round target, this appears to be a mistake from Ian Hogg’s book “The Encyclopedia of Weaponry”. No other source mentions a 12″ circle, which would be a mere 3.82 MOA. In reality the true drill target was a 48″ x 48″ square, roughly 15 times larger. (From 
This video shows a conventional chronograph with front and rear light sensors. The bullet first trips the front sensor and then the rear sensor as it flies over the unit. The difference in sensor time is used to calculate bullet speed. This is not the only kind of chrono in common use today. The popular
