Inertial Trigger is a Great, Low-Cost Upgrade for LabRadars

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

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.

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

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.”

Saturday at the Movies: Chronograph Tests and Comparisons

shooting chronography comparision product review test video saturday movie

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.”

Saturday at the Movies: Firearms Science Series — 7 Smart Videos

NRA firearms science videos ballistics chronography mil-dot eye dominance

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.

CLICK HERE to Access All 40 NRA Firearm Science Videos »

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.

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!

INTERNAL Ballistics — Cartridge Ignition and Bullet in Barrel


NRA firearms science videos ballistics chronography mil-dot eye dominance

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

pistol shooting science Jessie Duff NRA Ballistic PendulumThis 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.

Big Bore Brilliance — Paul Phillips Optimizes the .416 Barrett

global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bullets

Paul Phillips Ko2mPaul 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.

global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bulletsAfter 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

RCC Brass (CNC-machined)

Vihtavuori 20N29 Powder

RWS primers

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:

global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bullets
global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bullets

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.

High-Quality Portable Base for LabRadar Chronograph

If you currently own a LabRadar, or plan to buy one soon, there’s a smart new accessory you should consider buying. Matt Owens of ArkcoMachine.com offers a great, compact Quad Base for the LabRadar that works better than the flat, orange baseplate offered by the manufacturer.

Matt, aka “Arkcomatt”, explains: “These are machined from aluminum and put together with stainless steel screws. The rubber feet are held on with screws also. No more coming off. The legs have nylon washers between them and the base for smooth operation. The screws are torqued and thread locker applied. One of the best things is, with the standard attachment, it will fit in the case with the unit. No more having to take apart! Just fold the legs. It takes up less room on the bench and allows you to get it closer to the rifle. It is very stable and holds up very well in high winds.” ORDER BASE HERE.

arkcomatt swivel mount labradar quad baseArkco Machine’s folding Quad Base costs $89.95. The base offers better stability than the LabRadar factory mount, and is also easier to transport because it folds. This makes your LabRadar easier to deploy on a bench or when shooting prone.

Arkco Machine now offers handy swivel (ball) mounts for mounting your LabRadar to Arkco’s Quad Base. Choose either the Quick-Release Heavy-Duty Swivel Mount ($24.95, see photo at right) or the basic Light-Duty Ball Mount, just $10 (shown below). We like the Heavy-Duty unit because it can also be used for spotting scopes.

Arkco Machine also offers stainless spike feet for use when prone shooting. The spikes (shown below) screw in the same holes as the rubber feet.

labradar base unit arkcomatt stainless folding

Forum Member Praise Arkco Machine’s LabRadar Folding Base:
You can read user reviews of the LabRadar Quad Base in this Forum Thread.

Bullet-maker Bart Sauter has one of these bases now and he endorses it: “These bases are great for the LabRadar. Stable and compact — completely grab and go!”

Forum member Peterson1 agrees: “This is more stable than the Labradar base for my use–off a concrete BR bench, yet takes up less space. Also easier/quicker to set unit up and aimed at target. Never take the unit off for transport in LabRadar case. Only negative — you can’t trade in the factory LabRadar base toward purchase of this base. So buy smart the first time!”

Forum Member SkiUtah02 uses the base with optional spiked feet: “Met up with Matt at the Sierra Cup and bought my base with … spikes for the feet to put into the ground. Just had a chance to test it today and it worked great. I removed the rubber feet, and screwed in the four spiked feet, added a threaded-rod-coupling nut onto the bolt so that I could mount an old photography lighting stand swivel head to the base! Worked perfectly. Thanks Matt!”

Mobile Power Sources for SmartPhones, Tablets, & LabRadars

LabRadar FosPower USB Battery pack charnging LED

Today’s precision shooter is connected. He or she is likely to bring a number of electronic items to the range, such as a smartphone, tablet computer, Kestrel, LabRadar chronograph, and more. These digital devices all require electricity to operate. Unfortunately, most ranges don’t include convenient charging stations for your gadgets. Therefore you need to bring battery back-up. Here are three good options, with storage capacities from 10200 mAh to 42000 mAh. The first unit is fully weather-proof, so it is good for hunters and tactical shooters exposed to the elements. The largest power pack, with AC outlet, is quite versatile and works well on car-camping trips.

1. FosPower 10200 mAh Waterproof Charger, $29.99

FosPower USB Battery pack waterproof shockproof LED

When you’re at the range or on a hunt, it’s smart to have a USB-output battery pack for smart phone, target-cam monitor, even a LabRadar. There are many battery packs available, but most are fairly fragile, with exposed ports. This “ruggedized” FosPower 10200 mAh charger is different. It is waterproof, dust-proof, and shock-proof. (IP67 certified: dust and water resistance for up to 3ft/1m for 30 minutes under water.) It can handle all that a PRS competitor or hunter can dish out. It even has a handy LED light. Right now it’s priced at $29.99 with FREE Shipping for Prime members.

2. EasyAcc 20000 mAh Battery Pack with Fast Charging, $42.99

USB

If you want to charge multiple devices, such as a tablet and a LabRadar, you need serious capacity. The EasyAcc 20000 mAh battery pack can charge up to four devices simultaneously. Notably, this $42.99 Battery Pack charges faster than most other 20K packs. It has two power input ports, allowing it to fully charge in 6-7 hours. (We have another 20000 mAh battery unit that takes over 16 hours to fully charge!). This unit will charge an iPhone 7 six times, a Samsung S8 four times or an iPad Mini two times. Note, 78% of Amazon purchasers rated this unit Five Stars (with 13% Four-Star reviews).

3. Jackery 240Wh USB, 110v AC, 12v DC Power Station, $199.99

USB

Many folks have asked us “How can I use a laptop, chronograph, or electronic powder dispenser that requires 110 volt AC power when I’m at the range?” Sure you can take power from your car’s 12 volt cigarette lighter jack, but you’ll still need a very long cable and a 12 volt to 110 volt step-up transformer. If you run a cable from the parking lot to the bench or shooting bay you’ll have to leave a window open in your vehicle and fellow shooters can trip over the long cord.

A better solution is to get a portable, combo USB + 110 volt + 12 volt power unit. This versatile 240Wh Jackery Power Station will drive a 110v device, 12v units, PLUS charge a USB tablet and cellphone, all at the same time. You can run a LabRadar for DAYS with this advanced Lithium Ion power-pack. It will also power CPAP machines and other 12v devices. One nice feature is rapid charging. Before your range session or camping trip, plug this into the wall. It will get fully charged in about 3.5 hours from a 110v outlet. Also this unit can recharge from a paired Jackery solar panel ($179.99 sold separately, see below). By itself (without solar panel) the Jackery portable power source is $199.99 on Amazon. See Jackery Product Store.

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 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.”

NRA Firearm Science Videos Offer Insights on Many Topics

NRA firearms science videos ballistics chronography mil-dot eye dominance

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 Duff, 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 over forty videos in the Firearm Science Video Series. Here are five NRA videos, with links to others below. You’ll find all NRA Firearm Science Videos HERE

BULLET TRAJECTORY — Factors at Play and Zeroing Strategies

Host 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.

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!

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

pistol shooting science Jessie Duff NRA Ballistic PendulumThis 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.

JKL Inertial Trigger — Great Upgrade for LabRadar Chronograph

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

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 LabRadar’s 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.

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

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.

Chrono Test — LabRadar vs. MagnetoSpeed vs. Oehler 35P

labradar chronograph test magnetospeed V3 oehler 35P 6mmBR Ackley BRA

We see comparison tests of cars, cameras, and other hardware. But how about chronographs? What could we learn by setting up three different chronographs, and running a 20-shot string over all three at the same time. One of our Forum members, Randy S. (aka AAA) did that very test with three of the best chronographs you can buy: LabRadar, MagnetoSpeed, and an Oehler model 35P. The MagnetoSpeed was attached to the barrel of an F-Class rig, with the LabRadar placed on the left side of the shooting bench. The Oehler 35P was positioned about 23 feet downrange. The photo above shows the set-up. A 20-shot string was recorded with the results in a spreadsheet.

AAA talks about this interesting experiment in a Shooters’ Forum Thread. Here is his report:

Comparison Testing Three Chronographs

We all have our favorite chronograph. Each gives a number, but how would that number compare to the same round fired with another chronograph? I wanted to know so a friend and I set up the following test with three chronographs: LabRadar, MagnetoSpeed V3, and Oehler Model 35P.

For the test we fired Berger 105gr VLDs over the three chronographs simultaneously. The test rifle was my 6mm BR Ackley (BRA) F-class rig with fire-formed brass and 200 rounds on the new barrel.

Chronogaphs Tested
LabRadar
MagnetoSpeed V3
Oehler Model 35P
Temperature: 86 deg. F
Elevation: 854 feet
Cartridge: 6mm BRA (105gr Berger VLD)
Time between shots: 45 seconds

To start off, five rounds were fired to make sure all systems were recording and to warm the barrel. Then the test was 20 shots fired across all three instruments with 45 seconds between shots. The Oehler was set 7.5 yards from the muzzle so 12 FPS was added to the recorded value.

We were using the internal trigger on the LabRadar. The manual says the Vo indicated is the actual muzzle velocity when using the internal trigger, but not if using the Doppler. The 12 FPS Oehler adjustment (back to MV) was based on the Berger Ballistics Calculator.

The LabRadar Chronograph is on sale now through 12/7/2019. Buy for $499.95, a $60.00 savings.

Results of the Triple Chronograph Shoot-Out:

labradar chronograph test magnetospeed V3 oehler 35P 6mmBR Ackley BRA

LR-M is FPS variance between LabRadar and MagnetoSpeed V3. LR-O is FPS variance between LabRadar and distance-adjusted Oehler 35P. You can see all three chronos were very consistent. ES was identical with the MagnetoSpeed and Oehler 35P, while SD was identical with the LabRadar and Oehler 35P. CLICK HERE for spreadsheet.

The tester, Randy S. (aka AAA) says: “Judge for yourself, but I was impressed by all.”

Comments by Forum Members
Our Forum members expressed interest in this Triple Chronograph test. Some confirmed that the LabRadar and Magnetospeed give very similar FPS numbers, based on their own tests:

“Great test and thanks for sharing. I’ve tested my MagnetoSpeed and LabRadar together and results are always within 2-4 FPS of one another.” — Big D

“Very happy to see your numbers support my decision to buy a MagnetoSpeed. Had read reports comparing it to the Oehler and the numbers I get seem to be supported by my long range shooting results. Many thanks for taking the time and effort [to perform] this comparative test. Always good to get actual test results.” — Texas10

“I did a 4-shot test with my MagnetoSpeed and another shooter’s LabRadar a couple of days ago. The results were within 4 fps with the LabRadar being optimistic.” — Pat Miles

Forum Member Powderbreak studied AAA’s original spreadsheet from the chronograph trio test, then figured out the shot-by-shot FPS variance between the machines. He concluded that all the machines performed very well. Powderbreak posted:

Analyzing the Triple Chronograph Test — What Can We Conclude?

AAA did a great job of comparing the 3 chronos. What conclusions can be drawn?

1) I have not checked the manufacturer’s claims of accuracy, but the three chronos are very close to one another. There is no way for us to determine the actual true velocities, but we do not need to do so. Any of the chronos would be more than adequate for an accurate shooter.

2) The resolution of the three chronographs is actually pretty astounding. One foot per second (FPS) is a resolution of 0.033%.

3) AAA did a great job of reloading a very consistent round. With an extreme spread of 33 fps out of 3014 for 20 rounds, that is only 1.09% total spread of velocities.

4) There is a closer velocity match between the MagnetoSpeed and the LabRadar, but that does not mean the Oehler is less accurate. There is simply an offset between the Oehler and the other two. This could be due to the greater distance, the location, or the internal working of the Oehler.

5) Believe your chronograph, it is probably the most accurate reloading tool that you own.

Brian Litz of Applied Ballistics carefully explained the operation, set-up, accuracy and comparison of AB’s chronographs in his books. [Those books] are well worth the money, and give great insight into the workings of chronographs.” — Powderbreak

FosPower USB Battery pack waterproof shockproof LED

When you’re at the range or on a hunt, it’s smart to have a USB-output battery pack for smart phone, target-cam monitor, even a LabRadar. There are many battery packs available, but most are fairly fragile, with exposed ports. This “ruggedized” FosPower 10200 mAh charger is different. It is waterproof, dust-proof, and shock-proof. (IP67 certified: dust and water resistance for up to 3ft/1m for 30 minutes under water.) It can handle all that a PRS competitor or hunter can dish out. It even has a handy LED light. Right now it’s priced at $29.99 with FREE Shipping (on orders over $25.00).

2. EasyAcc 20000 mAh Battery Pack with Fast Charging, $37.99

USB

If you want to charge multiple devices, such as a tablet and a LabRadar, you need serious capacity. The EasyAcc 20000 mAh battery pack can charge up to four devices simultaneously. Notably, this $37.99 Battery Pack charges faster than most other 20K packs. It has two power input ports, allowing it to fully charge in 6-7 hours. (We have another 20000 mAh battery unit that takes over 16 hours to fully charge!). This unit will charge an iPhone 7 six times, a Samsung S8 four times or an iPad Mini two times. Note, 77% of Amazon purchasers rated this unit Five Stars (with 13% Four-Star reviews).

3. Webetop 42000 mAh USB, 12v DC, 110v AC Power Station, $108.99

USB

Many folks have asked us “How can I use a laptop, chronograph, or electronic powder dispenser that requires 110 volt AC power when I’m at the range?” Sure you can take power from your car’s 12 volt cigarette lighter jack, but you’ll still need a very long cable and a 12 volt to 110 volt step-up transformer. If you run a cable from the parking lot to the bench or shooting bay you’ll have to leave a window open in your vehicle and fellow shooters can trip over the long cord.

A better solution is to get a portable, combo 12 volt + 110 volt power unit. This versatile 42000 mAh Webetop Power Station will drive a 110v device, plus charge a tablet and cellphone, all at the same time. You can run a LabRadar for days with this power-pack. It will also power CPAP machines and other 12V devices. One nice feature is rapid charging. Before your range session or camping trip, plug this into the wall. It will get fully charged in 7-8 hours. It’s a bargain right now for $108.99 on Amazon.
