SHOOTING POSITIONS — Prone, Standing, Sitting, Kneeling

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.

F-Class competition grows in popularity every year. Unlike F-Open, the F-TR (Target Rifle) class is limited to the .223 Remington (5.56×45) or .308 Winchester (7.62×51) chamberings. F-TR rifles also use bipods rather than a front rest. But these are no ordinary Harris-style bipods. Modern F-TR bipods have a wide footprint for added stability and many F-TR shooters favor SEB Co-Axial joystick bipods (aka “Joy-Pods”). Today we are featuring an F-TR rig that showcases the types of components, and accessories used by top F-TR competitors — including a coaxial bipod and Labradar Chronograph. If you’re considering getting started in the F-TR game, take a close look at this modern F-TR build from Forum member DM.Oakes.

Modern F-TR Rig with Borden Action, Krieger Barrel, and SEB Joy-Pod
This handsome .308 Win F-TR rig features a smooth-running Borden BRM action, 30-inch 1:10″-twist Krieger barrel, and an X-Ring Laminated Wood stock. Up front is a coaxial “Joy-Pod” joystick bipod. This is a state-of-the art, wide footprint bipod used by many competitors at the Worlds in Canada. The long joystick allows the “driver” to quickly adjust both elevation and windage in a smooth, continuous motion. The Joy-Pod can be adjusted so it will hold setting during the shot — you don’t have to “hard-hold” the joystick. Many shooters let the joystick slide through their fingers as the rifle moves back on recoil. With a little practice (and careful placement of the rear sand-bag), the tracking is excellent and you can slide the gun right back to point of aim after each shot.

Action: Borden BRM
Trigger: Blue-printed Jewell BR
Barrel: Krieger 30″ / 4-Groove / 1:10″ twist (.30 Cal)
Chamber: .308 Winchester with 0.170 Freebore
Stock: X-Ring Laminated F-Class
Scope: Nightforce 12-42x56mm Competition
Potential Name: Blue Thunder

» Full LabRadar Field Test/Review by Ray Gross

If you are considering purchasing a LabRadar Chronograph system, we strongly suggest you read the very thorough and informative LabRadar Review by Ray Gross, past Captain of the USA F-TR team. Ray notes: “It takes me about 3 minutes to set up [my LabRadar] at the range. Because there are no downrange screens, I do not have to hold up other shooters on the range like I would when setting up a traditional chronograph. The convenience alone will mean that I will use it more often than my old chronograph. Every time I take it out, I enjoy it a little bit more.”

SUMMARY: This article reviews a device that “triggers” the LabRadar chronograph to register bullet speed. Rather than activate by sound or Doppler reading, this $35 JKL Inertial Trigger works from the rifle’s instantaneous recoil pulse when a shot is fired. After some frustration with his LabRadar when shooting at a range with reflective surfaces, our tester is now reporting that 100% of his actual shots are being captured correctly by his LabRadar chrono equipped with the JKL Inertial Trigger. He won’t use his LabRadar without it now. Other users have become instant fans of this inertial LabRadar trigger as well. It is very affordable and it works great. VIEW LARGE PHOTO.

JKL Inertial Trigger for LabRadar Chronograph

Product Review by F Class John
The LabRadar chronograph has been one of the most revolutionary tools in the shooting world because of how it collects velocity data, how it reports (and stores) that data, and, ultimately, the ease with which it can be positioned and operated. However, it’s not a perfect system. A majority of the complaints come from users whose LabRadars sometimes fail to record all the shots fired in a string. For the average plinker, this may not be an issue. But for serious shooters trying to do ladder tests or load development requiring all shots to be reported, it can be frustrating when a shot is missed.

Traditionally, LabRadar has recommended trying different settings that compensate for the gap between the unit and muzzle as well as well as having different options for how the unit recognizes a shot fired. While these options work to some degree, they aren’t a guaranteed fix especially when shooting at ranges with concrete baffles or with roofs, walls, and dividers that can alter sound waves. While nobody can precisely explain why shots are lost under certain circumstances, the fact remains it DOES happen. In addition, the default system can sometimes pick up stray shots from nearby rifles.

Not willing to give up on this sophisticated chronograph, many shooters have looked for a foolproof way to prevent such failures from happening. In fact, for this shooter, the frustration was so high that I actually sold my first LabRadar and went back to another chronograph before ultimately buying another LabRadar almost a year later. But I made that repeat purchase only after vowing to finding a way to make the LabRadar work — EVERY time, for EVERY shot.

See How JKL Inertial Trigger Works in this Video

JKL Inertial Trigger — Outstanding Product That Works Great
Enter the JKL Gen 2 Trigger for the LabRadar. This is an easy-to-use, inertial-driven trigger that activates simply from the recoil of your gun. The unit consists of a small rectangular pad attached to a long audio cable. All you do is plug in the audio cable, attach the pad to your gun with the provided hook and loop (Velcro) material. Then (important), you must change the LabRadar trigger settings from “Doppler” to “Trigger”. The unit works great and is easy to set up. In my experience, the unit will activate no matter where you place it on a stock. However the recoil of every gun is slightly different, so you will need to make sure you find a location that doesn’t interfere with your shooting setup.

An unexpected benefit of using the JKL trigger is that it gives you a larger area in which to place your Labradar unit, making it more convenient to setup on benches or range stations. I found this a welcome relief since the LabRadar originally seemed somewhat fussy about where I placed it. Now I can place the LabRadar in more convenient locations — as long as it’s still near my gun and pointed at the target correctly, I get consistent bullet speed data.

Are There Issues with “False Positives”?
If there is any downside to using the JKL Inertial Trigger, it’s that a very hard bump or aggressive working of the action can trigger a false reading. However these are easy to identify in your data, because the speed value is way lower than true fired shot values. Simply remove that low entry or otherwise ignore it in your calculations. To be fair, this “bump activation” really doesn’t happen very often once you get used to using the inertial trigger.

SUMMARY — Outstanding Accessory for LabRadar Users
Bottom line — if you own a LabRadar, then definitely get a JKL Inertial Trigger. Priced at just $35.00 this device is not expensive, yet it’s one of the most effective accessories you can buy for the LabRadar. I’ve recommended these inertial triggers to dozens of shooters. Every one of those guys who did buy a JKL trigger says they can’t imagine using a LabRadar without one. If you love what the LabRadar can do, but have been frustrated with shots not getting recorded 100% of the time, then definitely get yourself a JKL Inertial Trigger. It turns a good system into an amazing system. JKL Industries states that its inertial trigger “will work on anything from a .22 LR to a suppressed system or with standard rifle and brake.”

To optimize your loads and to generate precise ballistics tables, you need a quality chronograph. Having precise readings of bullet muzzle velocities lets you calculate ES and SD to determine the most repeatable load with least vertical dispersion. Very accurate velocity data is also essential to created a precise drop table for long range and to predict the effect of winds. There are many good chronographs on the market, ranging in price from around $100 to $1000, not counting tripods.

Today’s Saturday Movie showcase features a variety of modern chronographs. We include comparison tests, as well as video reviews of the new, small-format Bulletseeker Mach 4 and AndiScan Micro A2 Doppler Radar chronographs. If you are in the market for a new chronograph and have the resources, you should definitely consider one of these new small chronos, which are easy to set-up and can be mounted directly to your rifle. For those with a limited budget, MagnetoSpeeds still offer great performance for the price. However, you may have to conduct load tuning separately with the MagnetoSpeed removed.

Triple Chronograph Comparison Test
LabRadar, MagnetoSpeed, and Shooting Chrony Alpha Master

This video has an interesting comparison test with three chronograph devices operating at the same time. A Shooting Chrony Alpha Master unit was set up downrange, while a modern LabRadar was placed to the right side of the rifle. On the barrel of the rifle a MagnetoSpeed chrono was attached. This allowed the tester to compare shot velocity values from all three chrono systems at the same time. The video creator explained: “I was curious to see if my old [Shooting Chrony] chronograph could still give me useful velocity information compared to using the newer MagnetoSpeed and LabRadar.”

Chronograph Functions and Features — Vortex Nation Podcast

In this 78-minute video, experts from Vortex explaining how modern chronographs work. The discussion covers the technical features of various chronographs. Multi-time F-Class National Champion Ian Klemm and former sniper Tony Palzkill examine different chronograph types, explaining how they operate. Ian discusses the pros and cons of different chronograph designs, and provides many good tips for chronograph owners. This 78-minute discussion covers multiple chronograph designs, including LabRadar, MagnetoSpeed, and Caldwell Ballistic Precision. There is also extensive discussion of ballistics in the first 20 minutes.

MagnetoSpeed vs. Caldwell Ballistic Precision Chronograph

In this video the host compares a MagnetoSpeed with an older, first generation Caldwell Ballistic Precision Chronograph, mounted a few yards downrange on a tripod. The tester favored the Magnetospeed saying it was “incredibly accurate” while being much easier to set up and transport. He also says the MagnetoSpeed App was very “user-friendly”.

Bulletseeker Mach 4 Radar Chronograph (Rifle Mountable)

NOTE: Skip Forward to 5:40 to see the Bulletseeker field-tested as mounted on rifle and on tripods.

The Bulletseeker Mach 4 is a new radar chronograph that mounts directly to your rifle. The advanced Bulletseeker features 120 Ghz radar with a beam-forming lens. Developed in Europe, with made-in-Germany core components, this unit is sold in the USA for $999.00 by Longshot, trusted maker of long-range target cameras. We think this is a game-changer. You get advanced radar ON YOUR GUN, with no need to haul around a bulky LabRadar.

Comparison test with the Bulletseeker Mach 4 and LabRadar

Another Bulletseeker tester was very impressed: “Based on my experiences with the device it seems like a good product that does everything it advertises. All the benefits of a LabRadar without the drawbacks.” (SEE Product review HERE.)

AndiScan Micro A2 Doppler Radar Chronograph (Rifle Mountable)

In this video, our friend F-Class John tests the innovative, ultra-compact AndiScan Micro A2 Doppler radar chronograph. This unit is small enough that it can be fitted to your rifle, or attached to a front rest or mini tripod. John tested an early pre-production model. The production model is now available for 800 Euros on the SQI-AndiX eShop. The manufacturer notes: “The next large 2023 production series is expected to be ready by the end of February.”

Product Description: “The AndiScan Micro A2 is an advanced ballistic velocity Doppler radar for measuring muzzle velocity of projectiles. It operates in 24GHz frequency band. It is a highly integrated and extremely small form-factor device that is intended to be directly mounted on the rifle. This frees the user from a complicated setup alignment and it also allows to perform measurements under dynamic conditions. It is the first device [with] this form-factor on the public market.”

JKL Inertial Trigger for LabRadar

The JKL Inertial Trigger for the LabRadar is an easy-to-use, inertial-driven trigger that activates simply from the recoil of your gun. Rather than activate by sound or Doppler reading, the JKL Trigger works from the rifle’s instantaneous recoil pulse when a shot is fired.

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.

Paul Phillips is a past King of 2 Miles, and one of the world’s top Extreme Long Range (ELR) Shooters. He recently showcased one of his ELR rifles that shoots the .416 Barrett cartridge with huge, 550gr Cutting Edge bullets seated in CNC-machined RCC (Robertson Cartridge Company) brass that costs $10 per case.

Even with these giant-sized cartridges, Paul Phillips is getting remarkable accuracy. He recently went out to a snow-covered rifle range to do some testing. We include some test results in this article. Paul’s rig delivered 1.056″ to 1.748″ 3-shot groups at 500 yards. That’s .202 to .335 MOA for three shots. (1 MOA = 1.047″ at 100 yards, or 5.235″ at 500 yards). That’s very impressive accuracy for such a big cartridge with serious recoil.

Confidence is Gained from Consistent Accuracy

Report by Paul Phillips
After being retired from my 30 years of service in military and law enforcement, I started my own company, Global Precision Group LLC. We specialize in Long range shooting. I am currently doing some R&D for a new ammunition company, Ultimate Ammunition, (UA) out of Las Vegas. UA specializes in Military, Law Enforcement, and Custom ammunition.

On this particular day, it was a very cool 15 degrees F. I was testing ammunition for the .416 Barrett. Since winning the King of 2 Miles in 2019, my team has been looking at ways to make everything better. The competition is fierce and everyone is getting better and better. Finding single-digit Standard Deviations (SDs) is a must. Holding SDs under 5 FPS can be what it takes to win.

After several weeks of testing, I think I found the perfect combination for the .416 Barrett in my rifle. My optimal load runs about 3000 FPS using the following components:

Cutting Edge 550 Grain Solid Bullets with Tips

Loaded for ~3000 FPS load velocity goal

I figure if I can keep my 3-round groups under two inches consistently, I have a chance to win on any Sunday. The average group size of these groups was 1.47 inches at 500 yards. With big bore rifles it gets very costly to test. That is why I am limiting my test groups to 3 rounds. See below:

Note the single-digit Extreme Spread and SD for all of these three-shot groups, as recorded by the LabRadar (see below). The average SD for these three groups at 500 yards was about three.

NOTE: This is an animated GIF with THREE images, alternating every 4.5 seconds.

Not just the ammunition deserves credit. I also have to give credit to the quality Manson reamer, BAT action, Bartlein Barrel, Bix’N Andy trigger, Manners ELR stock, Nightforce Optic, and Accu-Tac bipod with my new P skis. All these gear/hardware items, combined with quality ammunition, allow these kind of groups.

Do you own a LabRadar chronograph, or perhaps you are planning to add one to your range gear this season? With a LabRadar, you don’t have to go downrange to set up the chrono on a tripod and fuss with bore-sighting. LabRadars are excellent chronographs, particularly when paired with an inertial trigger.

Here is an excellent accessory that can be easily fitted to LabRadars. This Edelkrone StandONE all-terrain foldable camera stand can provide a stable base when shooting from a bench or the ground. It can quickly and easily adjust to uneven ground so that your LabRadar sits properly vertical and square to the horizon. The versatile Edelkrone StandONE sells for $119.20 at B&H Camera.

Note how the StandONE can adapt to uneven ground through the multiple hinges on the legs.

Forum member X-47B found this stand and he says it works great with his LabRadar. He is a commercial photographer, so he is familiar with the latest and greatest camera stands. In our Shooters’ Forum he posted: “Working in commercial photography and video I come across all different equipment. When I got this Edelkrone StandONE folding base, I realized it is the perfect base for a LagRadar. Works on friction, no ball-head needed. It works on any terrain and folds up tiny, so it’s perfect for prone or the bench.” Stated load capacity is 15 pounds, and this is made to hold expensive camera gear, so there’s no problem placing a LabRadar unit on top.
