Every serious shooter needs to know the muzzle velocity (MV) for his load, so he can run ballistics solvers. And very consistent MV with low Extreme Spread (ES) and Standard Deviation SD is vital for consistent long-range shooting. You need good components and reloading techniques for low ES/SD. You want a good, reliable, and consistent chronograph to record your muzzle velocity — there are many good types now, including the compact Garmin Xero C1 and the handy Magnetospeed units which attach to your rifle.
Today we feature a new 55-minute video from Bryan Litz of Applied Ballistics. In this video Bryan explains how to measure muzzle velocity with various chronograph types and then explains some methods for optimizing your ES/SD. Bryan explains: “Muzzle velocity is an important variable for long range shooters. This video covers some key concepts for beginners and also goes into some advanced topics that are not normally encountered to keep it interesting for experienced shooters as well.”
This video from the manufacturer explains how to use the excellent Garmin Xero C1 radar chronograph. This popular new unit has proven to be user-friendly and very reliable. The ultra-compact size makes it easy to transport and deploy at the range.
Get a Good Ballistics App — Consider the NEW AB Quantum App
Once you have recorded your muzzle velocity successfully you can use the MV data with your known bullet BC and range altitude to plot the trajectory of bullet flight. This will tell you the correct scope elevation setting for the distance of your target. We recommend getting a good Ballistics App for your mobile device so you can run ballistics at the range.
Definitely check out the impressive new AB Quantum App from Applied Ballistics. Consumers can now download the AB Quantum App for either iOS (Apple) or Android devices. There is a free basic version, as well as an Elite subscription, which unlocks many more features for just $2.99/month or $19.99/year (see chart below).

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.
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!
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.
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 2.2 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.
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.

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.
