Applied Ballistics has released powerful new ballistics software, the Applied Ballistics Quantum™ App. This state-of-the-art mobile App provides a complete ballistics solver plus profile management tool for long-range shooting. Featuring an all-new user interface, AB Quantum™ includes a host of new tools and features for competitive shooters and hunters.
“Ballistics can be complicated, and it is our job to simplify what’s important so that shooters can hit targets”, said Applied Ballistics Founder/Chief Ballistician Bryan Litz. “The AB Quantum platform meets this goal and more. By integrating the ballistic solver with other support tools, shooters will have a complete management system to … put rounds on target faster and easier than ever before.”
Applied Ballistics Chief Technology Officer Nick Vitalbo said that the goal was “to create the most intuitive, feature-rich ballistics application on the market, seamlessly integrating with the entire Applied Ballistics ecosystem of products. AB Quantum™ will be our flagship platform, driving the future of AB-integrated devices [and transforming] the way [customers] use their existing AB-enabled products.”
Quantum™ Ballistics App — New Features Overview
AB Quantum™ creates a new paradigm for ballistic solvers and integration with Bluetooth®-enabled devices. With a host of new features, the platform is designed to save time and add performance for users of all skill levels. The all-new user interface is designed with single-handed use in mind, putting all major features just a swipe or tap away from any screen, which allows users to rapidly obtain solutions in the field or at a match. The simplicity and versatility of the app interface creates an intuitive experience for both new and experienced users.
Two new features — AB Quantum Connect™ and AB Quantum Sync™ — enable users to quickly connect to other AB-enabled devices and sync gun profiles between them in seconds, as well as back those profiles up to an encrypted server for peace of mind and easy restoration. The new platform automatically saves changes made to rifle profiles and updates connected devices. AB Quantum™ also includes customizable Range and Multi-Target tables. After creating a range or target card, it can easily be shared via email.
AB Quantum™ platform has impressive, innovative features:

Do you enjoy shooting pistols for sport, or perhaps you carry a handgun for self-defense? If you’re like most of us, you might benefit from a “refresher course” on the fundamentals of handgun shooting. The NRA has created a useful Infographic that covers important basics of handgun marksmanship — key things such as Sight Alignment, Trigger Control, and Handgun Hold.
Here are the first two (2) lessons. Click the link below to see all SIX (6) training topics: Sight Alignment, Sight Focus, Trigger Control, Breath Control, Hold Control, and Follow-Through.
Video Shows Sight Alignment, Grip, Stance, Trigger Control and More
In this USAMU video, SGT Shane Coley talks about the basics of sight alignment and trigger control. But then SGT Coley talks about other important control factors such as grip, arm position, and body stance. For rapid-fire shooting, you need to have a good arm and body positioning to control recoil and get back on target quickly. This video is a valuable complement to the NRA Infographic because it demonstrates all the important pistol fundamentals during live fire, at the range.
RCBS has a good successor to the venerable RCBS Trim Mate. The RCBS Brass Boss features six rotating stations that handle all your brass neck-brushing, chamfering, deburring, and pocket uniforming chores. The RCBS Brass Boss includes tools for all six stations: inside VLD chamfering tool, outside deburring tool, primer pocket cleaners (small/large), military crimp removers (small/large), primer pocket uniformers (small/large), case neck brushes (four diameters), and a tub of dry case neck lubricant. MSRP for the Brass Boss, RCBS Item 90390, is $219.99. The best price we found is $169.99 at Natchez — a very good deal.
This machine has two different rotation speeds for the toolheads. Four stations run at 350 rpm, while the two other stations run 57% faster, at 550 rpm. That give you a choice of spin speeds. You can work fast for tougher chores like military crimp removal, and slow down for inside-neck chamfering, which should be done carefully.
Larger and taller than the older RCBS Trim Mate, the Brass Boss has one more station (six vs. five), plus a more powerful motor. This should make the Brass Boss more competitive with the popular Lyman Case Prep Express, $168.59 on Amazon.
Keith Glasscock is one of America’s greatest F-Class shooters, as well as a highly respected wind coach. A High Master, Keith finished second overall at the 2021 NRA F-Class Long Range Championship in F-Open division. He also finished second at the 2020 F-Open Nationals, and second at the 2019 F-Open Nationals. His consistency is unrivaled, which means he definitely knows the secrets of competition shooting and loading ultra-accurate ammo. Recently Keith has started PRS/NRL competition, bringing his shooting skills to those popular tactical disciplines.
Keith has a great YouTube Channel with new content every week. On Keith’s Winning in the Wind channel, Keith offers 235+ informative videos on a wide range of topics including wind reading, reloading, component selection, load development, and training.
For today’s Saturday Video Showcase, we offer eight of our favorite Keith Glasscock videos. These cover many key topics — ballistics, barrel care, gunsmithing, bullet sorting, reloading, maintenance and more. Each video has important points that can benefit any competitive rifle shooter, whether you shoot in local 100-yard fun matches or compete at the National Level in F-Class, LR Benchrest, Palma, High Power, or PRS/NRL.
For most disciplines, if you want to achieve maximum accuracy and consistency, you should have your action bedded. This provides an optimal “seating” for the action which quells shot-to-shot motion and helps reduce vibration. Gunsmiths say a good bedding job can produce immediate benefits. In this video Keith Glasscock explains how to check your stock bedding and discusses the realistic benefits you can expect in group size and consistency over long strings.
Keith Glasscock is one of the very few PRS/NRL competitors who has shot F-Class at the very highest level, finishing second three times in F-Class National Championships. PRS/NRL and F-Class are very different disciplines with different challenges. F-Class is shot prone with time between shots and target distances from 600 to 1000 yards. In PRS/NRL competition, you are shooting from multiple positions, at many distances from 100 yards on out, with fast follow-up shoots. For F-Open, you want an extremely accurate load that can deliver sub-quarter MOA groups at 200 yards. For PRS/NRL you don’t necessarily need that level of accuracy (though it helps). But you also need a load that is very consistent, has relatively low recoil, but can also provide sufficient impact energy to clearly show a hit on distant steel. In this video, Keith Glasscock explains his reloading objectives for the two disciplines.
Hard carbon is the bane of rifle shooters. Hard carbon build-up in the barrel can adversely affect accuracy, and in extreme cases, can lead to increased pressure. If possible, you should clean your barrel(s) soon after a match (or shooting session) before the carbon fully hardens. We’ve used Wipe-Out Foam right after a match (with an hour soak time) and that dramatically reduced the amount of brushing required. In this video Keith Glasscock explains the negatives of hard carbon in your barrel, and he discusses how to diagnose the problem and how to remove the carbon build-up efficiently.
Benchrest and F-Class shooters don’t worry about magazines, because their rifles typically employ single-shot actions. However, with PRS/NRL rifles you’ll be shooting from a magazine. Likewise many hunting rifles use magazines to enable quick follow-up shots. In selecting the best magazine(s) for your rifle and discipline you need to consider a variety of factors including fit, capacity, reliability, and, yes, cost. In this video Keith Glasscock examines a variety of magazines for bolt-action rifles used in PRS/NRL competition as well magazines for hunting rifles.
Barrel break-in is a controversial subject. With premium finish-lapped barrels from top manufacturers, some ace F-Class shooters get away with hardly no break-in — just shoot for score right from the get-go. On high-quality custom barrels, we’ve had success with minimalistic break-in with a few wet patches ever 3 rounds for the first 20 rounds. However, with relatively rough factory barrels, you may get better long-term results with a systematic break-in process, even using specialized products on your patches. In this video Keith Glasscock explains break-in procedures he’s found to work for various barrel types and applications.
In general, we have gotten the best match results with loads showing an Extreme Spread (ES) under 13 FPS and an extremely low Standard Deviation (SD). We know that F-Class and ELR shooters competing at 1000 yards and beyond definitely want an extremely low ES to minimize vertical dispersion at long range. That said, some short-range Benchrest competitors look at group size more than ES/SD. In this video, Keith Glasscock talks about the reloading process and methods for lowering ES and SD. Proper brass prep is important, as is precise powder measuring. And long range shooters may want to test 3 or 4 different powder types to find the one that offers the best combination of accuracy and low ES/SD.
Should you sort your bullets? If so, should you sort by weight, OAL, base-to-ogive, or max diameter? Which factor? Well the answer is “it depends”. You need to carefully examine a couple dozen bullets from each batch to see how consistent they are. We had some Lapua bullets that were ultra-consistent with 97 out of 100 within .0015″ base to ogive length. We used those bullets unsorted to set a local range record at 600 yards. On the other hand if you find significant differences in weights, diameters, or bearing surface lengths, you probably should sort. One tip — many shooters do not consider the width difference in bullets. We have seen 6mm bullet diameters vary from 0.2428″ to 0.2436″. We have one 3-groove 6BR barrel that likes the skinny bullets and another 6-groove barrel that definitely prefers the fatter bullets.
The Kestrel 5700 Elite Wind Meter boasts sophisticated ballistics capabilities and LiNK Bluetooth connectivity. With the Kestrel 5700 Elite, once you enter data about bullet type (and BC), velocity, zero, and rifle, the Kestrel can calculate come-ups and wind corrections. The Kestrel 5700 can “talk” to a mobile device that runs the Applied Ballistics APP that contains bullet databases and allows you to easily enter key information such as muzzle velocity, bullet BC, zero distance, velocity, wind, and environmental factors. In this video Keith Glasscock explains the Kestrel 5700’s features including the ability to program sectors for a PRS/NRL match.

Caldwell Brass Retriever
Tired of bending over or kneeling down to retrieve your fired cartridge brass? For older shooters (including this Editor) getting down on the ground to pick up brass is tough on the lower back and knees. Here’s a product that makes brass retrieval quick, easy, and pain-free. The Caldwell Brass Retriever works quite well with a little practice, once you apply the correct pressure. While it won’t always grab every fired case, it will capture nearly all, and that can really make the job go much faster.
One owner praises this as a “very good tool” that is “a lot easier on my back.” While it can work on grass, gravel, and hard-packed earth, the unit works best on smooth, hard surfaces. Currently priced at $47.46 on Amazon, it is an affordable tool.
Caldwell states: “Spend less time bending over and picking up brass at the range and more time shooting. The Caldwell® Brass Retriever picks up brass, saving your back and time. The Brass Retriever can pick up rifle and pistol brass quickly and efficiently. The retriever comes complete with a roll cage separator that allows you to dump the collected brass into a bucket quickly. It is collapsible as well, making it convenient to transport. The retriever’s handle expands from 28″ up to 57″ tall.”
Brass Retriever Owner Reviews
Here are Amazon reviews from actual purchasers. It’s clear the device is not perfect and can miss a case or two. However, the Brass Retriever does grab the vast majority of brass on the ground, sized .223 Rem or larger diameter. This will save time and reduces stress on your back and joints:
“This thing … does a terrific job of collecting the brass from a standing posture quickly and efficiently. It helps to have the cases on a smooth surface like concrete or dirt without a lot of vegetation. But we used it on open desert yesterday and it collected nearly every case with a single pass. It’s now a permanent piece of gear in the stuff we take when target or ground squirrel shooting.” — Hans H.
“This WILL save your back. The only drawback is you can’t overload it with brass. After couple dozen pieces (or less) it will start dropping brass while you’re attempting to collect others. That’s the limitation (one of them). There is a short learning curve (15 min.) in which you’ll learn how much brass is too much And how you need to orientate the wires to pick up the brass. It doesn’t do as well on gravel or high grass as it does on a smooth, firm surface. Even with its limitations, it’s a keeper. Just empty every dozen or so pieces and it works very well.” — Jeff M.
Specialized Tool for .22 LR Brass
NOTE: The Caldwell Brass Retriever is designed primarily to recover reloadable rifle and pistol brass, with case diameters as fat as .223 Rem or larger. Some people state it can be used for smaller .22 LR cartridges too, but there is a much better product for that.
The UniqueTek Rimfire Brass Wizard is optimized for picking up .22 LR rimfire cases. It has a smaller basket with wires spaced closer together. It can also pick up pistol and rifle cartridge brass but will hold fewer cases than the original Brass Wizard or the Caldwell Brass Retriever. The Brass Wizard “Rimfire” The Brass Wizard “Rimfire” comes standard with the telescoping handle and includes a”Dumper” accessory.
Rifleshooter.com does some great original research — providing “hard data” you can’t find anywhere else. Here are the eye-opening results of Rifleshooter.com’s 6.5 Creedmoor barrel cut-down test. You may be surprised at the results. Read on…
What do you get when you cut a 6.5 Creedmoor-chambered barrel down to just over 16 inches? A lot more velocity than you might think. Our friends at Rifleshooter.com conducted a remarkable barrel cut-down test with 6.5 Creedmoor test rifle, shortening the barrel from 27 to 16.1 inches in one-inch increments. Surprisingly, with a 142gr Sierra MK, the total velocity loss (as measured with a Magnetospeed) was just 158 FPS, an average of 14.4 FPS per inch of barrel length. With the lighter 120gr A-Max bullet, the total velocity loss was 233 FPS, or 21.8 FPS average loss per inch of barrel.
Test Procedure
Five (5) rounds of each type of cartridge were fired at each barrel length and the velocity data was recorded with a MagnetoSpeed V3 barrel-mounted chronograph. The rifle was then cleared and the barrel was cut back one inch at a time from 27″ to just over 16″. NOTE: During this winter test, the air temperature was a very chilly 23° F. One would expect higher velocities across the board had the outside temperature been higher.
The photo below shows how the barrel was cut down, inch-by-inch, using a rotary saw. The barrel was pre-scored at inch intervals. As the main purpose of the test was to measure velocity (not accuracy) the testers did not attempt to create perfect crowns.
6.5 Creedmoor vs. Other Mid-Sized 6.5mm Cartridges
The 6.5 Creedmoor is a very popular cartridge with the tactical and PRS crowd. This mid-size cartridge offers good ballistics, with less recoil than a .308 Winchester. There’s an excellent selection of 6.5mm bullets, and many good powder choices for this cartridge. When compared to the very accurate 6.5×47 Lapua cartridge, the 6.5 Creedmoor offers similar performance with less expensive brass. For a tactical shooter who must sometimes leave brass on the ground, brass cost is a factor to consider. Here’s a selection of various 6.5mm mid-sized cartridges. Left to right are: 6.5 Grendel, 6.5×47 Lapua, 6.5 Creedmoor with 120gr A-Max, 6.5 Creedmoor with 142gr Sierra MK, and .260 Remington.
When asked to compare the 6.5 Creedmoor to the 6.5×47 Lapua, Rifleshooter.com’s editor stated: “If you don’t hand load, or are new to precision rifle shooting, get a 6.5 Creedmoor. If you shoot a lot, reload, have more disposable income, and like more esoteric cartridges, get a 6.5×47 Lapua. I am a big fan of the 6.5×47 Lapua. In my personal experience, the 6.5×47 Lapua seems to be slightly more accurate than the 6.5 Creedmoor. I attribute this to the quality of Lapua brass.” Now that Lapua offers 6.5 Creedmoor brass with small primer pockets, the 6.5 Creedmoor is even more attractive.
The creator of Rifleshooter.com also operates a Custom Rifle Building enterprise and gun shop in Long Island, New York: 782 Custom Guns Ltd.. He tells us: “We offer an unparalleled level of gunsmith machine shop services in the Long Island region. From precision rifles (USMC M40A3/A5/A6 XM3 clones) to customized Remington 870 and Mossberg 590 shotguns, and customized 1911s, chances are if you can dream it, we can build it!”
Ask 10 shooters about barrel cleaning and you’ll get 10 different opinions. This reflects that fact that different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa). To come up with the right solution, first you must understand the nature of the fouling in your barrel.
John Krieger Interview with AccurateShooter at SHOT Show:
The debate about the proper care of a match barrel is a hot one, spiked with folklore and old wives’ tales, Lohman said. He and his staff set out to set the record straight: “We tried to interject some science into the discussion of cleaning a match barrel,” he explained. In his article, Lohman writes:
Why worry about a little barrel fouling when the throat is subjected to a brutal 5,600° F volcano at 55,000 PSI? To investigate these and other questions about taking care of a match barrel, we spoke with a dozen experts and share their knowledge in this first of a series of articles.
After listening to folks who shoot, build barrels or manufacture cleaning solvents for a living, we concluded that even the experts each have their own unique recommendations on how to care for a match barrel. But they all agree on one thing — the gun will tell you what it likes best. Because the life expectancy of a match barrel is about 1,500 to 2,500 rounds, the objectives of cleaning one should include: preserve accuracy, slow the erosion, and remove fouling — all without damaging the gun. This article doesn’t claim that one cleaning method is better than the next. Rather, we set out to interject a little science into the discussion and to share some lessons learned from experts in the field.

For this Sunday GunDay article we feature a “blast from the past” — David Tubb’s engineering tour de force, the Tubb 2000, or “T2K” for short. With the remarkable T2K, David earned multiple NRA High Power championships, and David shot the first-ever perfect score in the NRA Long-Range “any sights” championship two decades ago.
Our write-up this week focuses mostly on “hardware” because David’s performance with the rifle speaks for itself. He has won eleven High Power National Championships at Camp Perry, and in 2004 David mounted a scope to his rifle and captured the Long-Range “any sights” Championship with a 1450/1450, the first and only perfect score ever logged at Camp Perry. He did this all with his trusty 6XC-chambered T2K, shooting the DTAC 115gr bullet in a 1:7.5″-twist Schneider P5 barrel. For more information about this remarkable competition rifle, read on.
[Editor’s NOTE: Because this is an article from our older Archives, some technical details may have changed with time. For all specifications on current TUBB rifles visit DavidTubb.com.]
Mag-Feed Action with Unique Bi-Camming Bolt
The action is machined from 17-4 stainless steel to true benchrest quality standards. The design features a solid top with a loading port. This increases action stability, stiffness, and strength. The loading port is easily accessible and is angled to aid the shooter in single loading rounds. The Tubb 2000 is fed via 10- or 20-round box magazines.
“I prefer using 20-round magazines with the Tubb 2000 because it provides a secure hand hold when shooting off the bipod. For across the course competition, the 10-round magazines are the best choice as they do not encumber sling-supported shooting positions. There is no difference in the functioning or reliability of either capacity magazine.”
One-finger Bolt Operation
Low effort bolt operation was a key goal in the design of the Tubb 2000 action. The exclusive bi-camming design employs two cams that engage during bolt lift to radically reduce bolt lift effort. Bolt lift is 75 degrees. The cone-faced bolt has two locking lugs which are narrower and taller than on conventional actions. This design allows the magazine to be mounted higher in the action for smoother, more positive feeding. The bolt handle is designed for superior performance in sustained fire operation. Its ergonomic shape allows operation with a single finger, if desired. The bolt is machined from 8620 carbon steel and rides back into the butt extension, under the shooter’s face so the bolt can be operated without the shooter having to change his head position. This low center of gravity also improves the rifle’s feel and performance under recoil.
The action features a full-length Picatinny rail that will accept Weaver®-style mounts. The action’s adjustable sight mounting system allows the rail to be mounted at one of three pre-set mounting angles — 0, 5, and 10 degrees — to allow the shooter to level the sights to fit his shooting style. A custom base is available to mount match iron sights. All barrels have a small section at the muzzle turned down to accept a clamping-style front sight mount or cant indicator.
The T2K’s Lock Time is ONE millisecond — over three times faster than a Model 70 Winchester.
Barrel Configuration
Tubb 2000 rifles featured hand-lapped stainless steel match barrels with the exclusive “Tubb Contour.” This unique contour maximizes accuracy and minimizes weight — it’s the perfect balance. According to David: “It’s a contour where the barrel wouldn’t shoot one bit better if it was one bit bigger.” The Tubb 2000 was conceived as a “switch barrel” gun — it’s designed to be easily re-barreled by the customer. This feature means that the same rifle can support different calibers and shooting disciplines. Finished barrels in a variety of calibers were available for “do-it-yourself” installations. The gun shown here has a Schneider barrel.
The Tubb 2000 has, over the years, been offered in a variety of chamberings including: .22-250; .243 Winchester; 6mmBR Norma (6BR); 6XC; .260 Remington; 7mm-08; and .308 Winchester. Available accessories include finished barrels, extra 10- or 20-round magazines, cleaning rod guide, adjustable bipods, custom adjustable handstop, fore-end weight rail, and cant indicator.
Trigger, Stock Adjustment and Other Features
The Tubb 2000 uses the superb Anschütz® fully-adjustable two-stage trigger (with safety); one of the finest available to the precision rifleman. This trigger can also be adjusted to provide single-stage operation. The buttstock assembly, forend, buttstock clamping block, and magazine housing, trigger guard assembly are made from 60-series aluminum, hard anodized in the customer’s choice of 6 colors: light and dark teal, purple, red, forest green, and black. (The T2K Tactical (see below) comes in matte black only.) These four parts are each available in any of the listed colors, allowing the purchaser to design his own distinct rifle.
The buttstock is FULLY adjustable for length, height, cant (angle), and offset. The cheekpiece is adjustable for height. An easily accessible knurled wheel allows the shooter to adjust the cheekpiece from the shooting position. Shooter comfort is further augmented by an ergonomic pistol grip. All adjustment features on the Tubb 2000 were designed for easy shooter access. The butt extension, clamping block, shock housing, and buttplate all have index marks to allow the shooter to record and repeat adjustment settings. The tubular fore-end can be rotated and positioned to accommodate the shooter’s preference. An integral accessory rail accepts a custom adjustable handstop or bipod. The fore-end also incorporates a built-in barrel heat wave blocking system which eliminates optical distortion in the sighting plane.”
David Tubb Explains T2K Stock Adjustments
I advocate setting stock length a little longer than most people might. I am a firm believer that it is best to “reach” slightly for the pistol grip as this ensures a strong, secure hold on the rifle. I pull the rifle firmly into my shoulder pocket when shooting offhand, and also prefer to have what I would characterize as very firm contact between rifle butt and shoulder in the sitting and prone positions as well. When using a sling in prone or sitting, stock length (and sling tension) should be great enough so that, at the least, you have to push the buttpad forward with your hand in order to place the stock into the shoulder pocket. My buttstock is shortest offhand and longest prone. If my standing setting is “0”, I’m usually out about 1-1/2 inches for sitting and about another inch for prone. I have found that many people tend to shoot with a stock that’s too long in sitting and too short everywhere else.
I have found the cast off/on adjustment feature on the buttstock to be of great help to me in attaining the natural shooting positions I desire. For prone, I offset the clamping block so the buttplate moves outward [the index mark on the clamp is to the right of center on the scale on the receiver extension tube]. I swing it a little bit inward for offhand and slightly more inward for sitting. The amounts of cast on/off (in clock-face terms) are approximately 6:30 for standing, 4:30 for prone, and 8:00 o’clock for sitting.
Stock Length Adjustment Procedure
The buttstock is adjustable in length 4+ inches. This adjustment is accomplished by moving the buttplate tube in or out after loosening the four screws on the clamping block. Ensure that the buttstock tube is fully contained in the block. The extent of rearward (lengthening) movement is determined by the front of the buttstock tube fitting flush with the front of the block.
Stock Cast and Cant Adjustment Procedure
The buttstock is adjustable for cast or offset by loosening the four screws on the clamping block and swiveling the block on the receiver extension tube. The buttplate itself is adjustable for cant up to 360 degrees and after loosening the screw directly in the center of the rubber recoil pad is adjustable for height at approximately 1-1/2 inches. The cheekpiece is adjustable vertically approximately one inch. The vertical cheekpiece adjustment is accomplished via the top knurled ring. The lower knurled ring will then secure the setting.

There are many tactical-style video producers on YouTube. Many of these guys, to be honest, aren’t very knowledgeable about firearms, nor are they particularly good shooters. By contrast, videos hosted by Tactical Hyve regularly feature top Action Pistol, PRS and 3-gun competitors as well as military SPECOPS veterans. The vets include SEAL team members who really know their stuff. The Tactical Hyve YouTube channel currently hosts over 560 videos! Here are seven of our favorite Tactical Hyve videos featuring highly-skilled instructors.
1. How to Aim a Pistol with Iron Sights or Red Dot
We recommend this video for persons training for a CCW permit, or who are getting started in pistol shooting competition. The video shows proper technique for using iron sights. In addition, it offers some important advice for shooting with Red Dots. Shooting with Red Dot sights can be easier than with iron sights because you only have to put the dot on the target, rather than align front blade with rear notch. But it does take some familiarization to get things right. And persons with astigmatism can have challenges with Red Dot sights.
2. Five Most Common Pistol Shooting Mistakes
In this video, Myles, the founder of Tactical Hyve, talks about the five most common pistol shooting mistakes he sees in classes and how to correct them. Many folks begin pistol shooting without a qualified instructor. Or they try to imitate what they see on TV. This can lead to new pistol shooters forming bad habits. This video helps handgunners correct those bad habits. This popular video has 1.9 million views.
3. Dry-Fire Techniques with Pistol Master Champion J.J. Ricaza
Released on 8/4/22, this is the latest video from the Tactical Hyve YouTube channel. The featured shooter, J.J. Ricaza, a multi-time Steel Challenge champion, is one of the top 10 action pistol shooters in the country. Racaza show how to dry fire like a grandmaster in this video.
