Measure Pull Weight with Lyman Electronic Trigger Pull Gauge

lyman digital electronic adjustable trigger pull weight gauge

We like Lyman’s Electronic Digital Trigger Pull Gauge, which is faster and more precise than the previous model. The latest Lyman Pull Gauge measures trigger pull weights from 1 ounce to 12 pounds with resolution of 0.1 ounces (2.8 grams). It features an adjustable, 4-position rod which retracts into the gauge body. We think that anyone running match triggers below 2.5 pounds pull weight should have a gauge like this. Among the pull gauges on the market, we think the Lyman unit offers great performance for the price.

Good Pricing Currently with Major Discounts

This Lyman Pull Gauge has a $69.95 MSRP, but it’s now on sale at many vendors. Grab one of these gauges for $58.99 at MidwayUSA, $52.95 on Amazon, and $58.09 at Palmetto SA.

Features: More Precise Strain Gauge | Improved Grip Shape | Adjustable Rod Lengths

Lyman’s Electronic Digital Trigger Pull Gauge is designed to be the fastest and most accurate trigger pull gauge available. State-of-the-art strain gauge technology allows for repeatable accuracy of 1/10 ounce (2.8 grams). The gauge features a large, easy-to-read LCD display and you can switch from ounces to grams with the push of a button. The gauge can also deliver a pull weight average of the last 10 readings. That’s very helpful when working with factory triggers that may not be very consistent.

The Lyman Trigger Pull Gauge features a solid, collapsible rod with four locking positions. Being able to adjust length makes it easier to use the gauge with a wide variety of firearms — pistols, rifles, and shotguns. The locking feature prevents the rod from flexing when applying pressure to the trigger. When not in use, the rod conveniently collapses into the gauge body, making the whole unit more compact. The new Trigger Pull Gauge comes in an internally-padded plastic case that can be easily stored in a drawer or on your work bench.

How to Prep Once-Fired Lake City 5.56 Brass for Match Use

The U.S. Army Marksmanship Unit (USAMU) regularly published reloading “how-to” articles on the USAMU Facebook page. One excellent “Handloading Hump Day” post covered preparation of once-fired 5.56x45mm brass. This article, the first in a 3-part series, has many useful tips. If you shoot a rifle chambered in .223 Rem or 5.56x45mm, this article is worth reading. You can obtain once-fired Lake City 5.56x45mm brass for less than half the cost of premium .223 Rem brass.

This week, Handloading Hump-Day will answer a special request from several competitive shooters who asked about procedures for morphing once-fired GI 5.56mm brass into accurate match brass for NRA High Power Rifle use. The USAMU has used virgin Lake City (LC) 5.56 brass to win National Championships and set National Records for many years. In this 3-part series, we’ll share techniques proven to wring match-winning accuracy from combat-grade brass.

GI brass has an excellent attribute, worth noting — it is virtually indestructible. Due to its NATO-spec hardness, the primer pockets last much longer than most commercial brass when using loads at appropriate pressures.

Preparing Once-Fired GI 5.56 Brass for Reloading (Part 1 of 3)

Assuming our readers will be getting brass once-fired as received from surplus dealers, the following steps can help process the low-cost raw material into reliably accurate components.

1. Clean the Brass
First, clean the brass of any dirt/mud/debris, if applicable. Depending on the brass’s condition, washing it in a soap solution followed by a thorough rinsing may help. [This step also extends the life of the tumbling media.] Approaches range from low-tech, using gallon jugs 1/2 full of water/dish soap plus brass and shaking vigorously, to more high-tech, expensive and time-consuming methods.

cleaning Lake City 5.56 brass

2. Wet-Tumbling Options (Be Sure to Dry the Brass)
When applying the final cleaning/polish, some use tumblers with liquid cleaning media and stainless steel pins for a brilliant shine inside and out, while others take the traditional vibratory tumbler/ground media approach. Degree of case shine is purely personal preference, but the key issue is simple cleanliness to avoid scratching ones’ dies.

If a liquid cleaner is used, be SURE to dry the cases thoroughly to preclude corrosion inside. One method is to dump the wet brass into an old pillow case, then tilt it left/right so the cases re-orient themselves while shifting from corner to corner. Several repetitions, pausing at each corner until water stops draining, will remove most water. They can then be left to air-dry on a towel, or can be dried in a warm (150° F-200° F max) oven for a few minutes to speed evaporation.

Shown below are Lake City cases after cleaning with Stainless Media (STM). Note: STM Case cleaning was done by a third party, not the USAMU, which does not endorse any particular cleaning method.

NOTE: The USAMU Handloading (HL) Shop does not RE-load fired 5.56 brass. We use virgin LC brass with our chosen primer already staked in place. However, our staff has extensive personal experience reloading GI brass for competition, which will supplement the Shop’s customary steps. In handloading, as in life, there are many ways to accomplish any given task. Our suggestions are note presented as the “only way,” by any means. Time for loading/practicing is always at a premium. Readers who have more efficient, alternative methods that maintain top accuracy are invited to share them here.

3. Inspect Every Case
Once dry, inspect each case for significant deformation (i.e., someone stepped on it), damaged mouths/necks and case head/rim damage. Some rifles’ ejectors actually dig small chunks of brass out of the case head — obviously, not ideal for precision shooting. Similarly, some extractors can bend the case rims so badly that distortion is visible when spinning them in one’s fingers. These can be used for plinking, but our match brass should have straight, undamaged rims.

Dented case mouths are common, and these can easily be rounded using a conical, tapered tool, [such as a .223 expander mandrel. A dummy 7.62 or .30-06 cartridge with a FMJ spitzer can also work.] If most of your brass is of one headstamp, this is a good time to cull out any odd cases.

4. Check the Primers Before Decapping
Your clean, dry and inspected brass is now ready for full-length sizing, decapping and re-priming. Historically, primer crimps on GI brass have caused some head-scratching (and vile language) among handloaders. Our next installment will detail efficient, easy and practical methods to remove primer crimp, plus other useful handloading tips. Until next week, Good Shooting!

Accuracy Potential of Mil-Surp 5.56×45 Brass
So, how accurate can previously-fired GI surplus brass be in a good National Match AR-15? Well, here’s a data point from many years ago that might be of interest. A High Power shooter who wrote for the late Precision Shooting magazine took a Bill Wylde-built AR match rifle to a registered Benchrest match. He had no difficulty obtaining consistent 0.5-0.6 MOA accuracy at 200 yards using LC brass and a generic “practice” load that was not tuned to his rifle.

Happy New Year: A Stellar Tactical Six for 2026 — Gavin’s 6GT

gavin gear 6GT alpha brass krieger barrel NRL PRS MDT Chassis

For the very first day of 2026 we present a precision rifle built with a modern 6mm cartridge — the 6GT. Developed by George Gardner of G.A. Precision and Tom Jacobs of Vapor Trail Bullets, the 6GT was designed to have the efficiency of a 6mm Dasher without the need for case forming. It was also designed with a longer case body so it feeds better from magazines. Even with the added capacity, the 6GT is still very efficient, and can achieve good velocities with less powder than a 6mm Creedmoor.

Today’s feature rifle was smithed and tested by Gavin Gear of UltimateReloader.com. Gavin did all the gunsmithing — chambering the barrel, fitting the muzzle brake, and even laser engraving the barrel. In building this 6GT rifle, Gavin used top-tier components: BAT TR action, Krieger 28″ 1:7.5″-twist 4-groove 6mm barrel, TriggerTech Diamond Rem 700-compatible trigger, and Area 419 Hellfire Muzzle Brake. The barreled action was then fitted in a handsome and rugged MDT ACC Chassis. On top is a Zero Tech 4.5-27×50mm FFP Trace Advanced scope in 30mm Hawkins Precision high rings.

We recommend you watch the video above — it covers the rifle build, load development, and then features some remarkable shooting sequences across snowy hills in the Pacific Northwest. Gavin’s team actually used a drone to capture overhead footage of the location.

After developing a promising load with Berger 109gr LRHT bullets, Varget powder, and Alpha brass, Gavin literally headed for the hills to test his new rifle at longer ranges, shooting from bipod. His load had shot well under half-MOA at 100 yards in testing so he was hoping he could hit multiple steel targets positioned at 340 yards, 760 yards, and 1000 yards. Indeed he did, proving the rifle’s great accuracy and Gavin’s fine trigger-pulling skills. You can see the hits at these time points in the above video:

Building Gavin’s 6GT Precision Rifle

Gavin Gear did all the gunsmithing on this project, using his own Precision Matthews TL-1660 lathe for the chambering with an Alpha carbide 6GT reamer. The barrel work took about four hours total. Shown below is the reamer cutting the chamber, which was finished with a 0.170″ freebore and 0.270″ neck diameter. For other brands of brass you might want the chamber to have a larger 0.272″ neck diameter.

This project when smoothly, with Gavin able to install the barreled action in the MDT Chassis and fit the buttstock in an hour or so. So total build time was about five hours. One nice “finishing touch” on the project was laser engraving the 28″ Krieger barrel — a process you can see in the video below.

About the 6GT — Sort of a 6 Dasher on Steroids

6GT 6mm GT comparison 6mm Dasher 6.4x47 Lapua

alpha munitions 6mm GT 6GT

6GT Cartridge Design Features

The 6GT was designed to have an optimal length and capacity for mag-fed PRS/NRL tactical rifles. The 6GT is longer than a 6mmBR and 6 Dasher, but shorter than a 6mm Creedmoor and 6.5×47 Lapua. That gives the 6GT ample case body length to feed reliably from a magazine, while the case capacity is sufficient to run popular powders at reasonable pressures. It has a 35-degree shoulder angle.

On paper the 6GT seemed like the perfect cartridge for PRS- and NRL-style centerfire competition. It has the low recoil of a 6 Dasher, with good feeding and mag compatibility. With the 6GT, a competitor can push 6mm 105gr bullets at 3000+ FPS or run heavier bullets at ~2950 FPS. With this 28″ Krieger barrel, Gavin actually achieved 3004 FPS running 109gr Bergers.

On the G.A. Precision website, the qualities of the 6GT are listed as follows:

gavin gear 6GT alpha brass krieger barrel NRL PRS MDT Chassis

Loading for the 6GT

Gavin started with quality Alpha Munitions brass. The cases were then annealed with an AMP Annealer and trimmed to length with a Henderson powered trimmer (see video below). After sizing with a Forster Co-Ax press, Federal SR Primers were seated using a Primal Rights competition seater. Next the powder was measured with an A&D FX120i force restoration scale. Finally, the Berger 109gr LR Hybrid Target bullets were seated with a Forster Micrometer die, again using the smooth Forster Co-Ax press.

Initial Load Testing with Berger and Hornady Projectiles

Before it got cold and snowy, Gavin did load development, shooting from a bench with a Sinclair front rest. The Krieger cut-rifled barrel was accurate right from the start and Hodgdon Varget powder proved to be a very good choice for the 6GT.

Gavin’s 6GT boasts a MDT ACC short action chassis with SRS-X Elite buttstock, vertical grip, and MDT CKYE-POD Bipod.

Gavin did initial load testing with both Hornady 110gr A-Tip Match and Berger 109gr Long Range Hybrid Target bullets. The Berger 109gr LRHT bullets were the most promising. A variety of charge weights were tested, with Gavin settling on 34.6 grains of Varget. This delivered fine accuracy with a 3004 FPS muzzle velocity. Group size measurements with this load are shown in the chart. At 100 yards, four three-shot groups averaged 0.361 MOA, and the rifle produced a nice 0.387 MOA (0.405″) five-shot group.

Cut-Rifled Barrels — The History of the Cut-Rifling Process

Pratt & Whitney Cut rifling hydraulic machine

You’ve probably heard of cut-rifling, but did you know this process was invented in Germany nearly 500 years ago? Read on to learn more about how a cut-rifled barrel is made…

The cut-rifling process, used by leading barrel-makers such as Bartlein, Blake, Brux, and Krieger can yield a very high-quality barrel with a long useful life. Cut-rifled barrels have been at the top in short- and long-range benchrest competition in recent years, and cut-rifled barrels have long been popular with F-Class and High Power shooters.

You may be surprised to learn that cut-rifling is probably the oldest method of rifling a barrel. Invented in Nuremberg around 1520, the cut-rifling technique creates spiral grooves in the barrel by removing steel using some form of cutter. In its traditional form, cut rifling may be described as a single-point cutting system using a “hook” cutter. The cutter rests in the cutter box, a hardened steel cylinder made so it will just fit the reamed barrel blank and which also contains the cutter raising mechanism.

Above is a computer animation of an older style, sine-bar cut-rifling machine. Some machine features have been simplified for the purposes of illustration, but the basic operation is correctly shown. No, the cut-rifling machines at Krieger don’t use a hand-crank, but the mechanical process shown in this video is very similar to the way cut-rifling is done with more modern machines.

Kolbe Border Barrels Firearms ID

Read About Cut-Rifling Process at FirearmsID.com
To learn more about the barrel-making process, and cut-rifling in particular, visit FirearmsID.com. There you’ll find a “must-read” article by Dr. Geoffrey Kolbe: The Making of a Rifled Barrel. This article describes in detail how barrels are crafted, using both cut-rifling and button-rifling methods. Kolbe (past owner of Border Barrels) covers all the important processes: steel selection, hole drilling, hole reaming, and rifling (by various means). You’ll find a very extensive discussion of how rifling machines work. Here’s a short sample:

“At the start of World War Two, Pratt & Whitney developed a new, ‘B’ series of hydraulically-powered rifling machines, which were in fact two machines on the same bed. They weighed in at three tons and required the concrete floors now generally seen in workshops by this time. About two thousand were built to satisfy the new demand for rifle barrels, but many were broken up after the war or sold to emerging third world countries building up their own arms industry.

Pratt & Whitney Cut rifling hydraulic machine

Very few of these hydraulic machines subsequently became available on the surplus market and now it is these machines which are sought after and used by barrel makers like John Krieger and ‘Boots’ Obermeyer. In fact, there are probably less of the ‘B’ series hydraulic riflers around today than of the older ‘Sine Bar’ universal riflers.

The techniques of cut rifling have not stood still since the end of the war though. Largely due to the efforts of Boots Obermeyer the design, manufacture and maintenance of the hook cutter and the cutter box have been refined and developed so that barrels of superb accuracy have come from his shop. Cut rifled barrel makers like John Krieger (Krieger Barrels), Mark Chanlyn (Rocky Mountain Rifle Works) and Cliff Labounty (Labounty Precision Reboring)… learned much of their art from Boots Obermeyer, as did I.” — Geoffrey Kolbe

Mounting Options for Ballistics Data Displays & Come-Up Tables

mdt m-lok card PRC dope roller quick detach qd ballistic data turret holder come-ups knob

When shooting any match that requires moving back and forth between multiple target distances it is very handy to have your ballistics data, i.e. your “come-ups”, placed within easy view. That way you can instantly see your elevation for various target distances in seconds. This can really help a PRS/NRL competitor on timed stages. And having a convenient “Dope” display of elevation at various distances can also benefit varminters who are shooting critters. In our varmint hunters we targeted p-dogs from about 80 yards out to 500+.

PRC DOPE Roller QD Ballistic Data Turret

PRC dope roller quick detach qd ballistic data turret holder come-ups knob

The PRC DOPE Roller QD Ballistic Data Turret provides a handy, low profile display of windage and elevation data. You can see your “dope” without breaking position from behind the rifle. Then simply rotate the knob to display data from various distances. The ballistic data is placed by wrapping a simple 1″ x 3″ adhesive address label around the outside surface of the DOPE Roller. This handy quick-detach roller retails for $64.95 from Precision Rifle Components.

MDT M-LOK Data Card Holder

mdt m-lok card PRC dope roller quick detach qd ballistic data turret holder come-ups knob

The MDT M-LOK Data Card Holder has an adjustable neck allowing you to easily position your ballistics data for optimal viewing. Data entries are written on on a reusable card that attaches with Velcro. The Data Card Holder Kit comes with hardware to mount to any M-Lok rail. In addition the card holder fits directly to an MDT ACC chassis attachment point. This MDT kit includes: M-LOK Data Card Holder, Wet Erase Data Card, Wet Erase Marker, and installation hardware. NOTE: The Card Holder sticks out about 6.7″ when fully extended, but arm links can be removed to make the arm shorter. The unit folds flat for storage. This complete kit is $59.95 at Creedmoor Sports.

Warne Universal Data Card Holder

warne m-lok card PRC dope roller quick detach qd ballistic data turret holder come-ups knob

The Warne Universal Data Card Holder easily attaches to the scope tube, in left or right configurations, for a universal fit. Data is displayed in a convenient location to make quick and accurate target transitions, and the articulating arm allows for low profile storage while not in use. The Warne Universal Data Card Holder retails for $88.49 at Warnescopemounts.com. Three ring sizes are offered: 30mm, 34mm, 35mm. A 50-pack of Warne Data Card label refills is currently $16.99 from Warne.

ballistics data scope coverScope-Cover Mounted Ballistics Table
Another option is to place your ballistics card on the back of the front flip-up scope cover. This set-up is used by Forum member Greg C. (aka “Rem40X”).

With your ‘come-up’ table on the flip-up cover you can check your windage and elevation drops easily without having to move out of shooting position.

Greg tells us: “Placing my trajectory table on the front scope cover has worked well for me for a couple of years and thought I’d share. It’s in plain view and not under my armpit. And the table is far enough away that my aging eyes can read it easily. To apply, just use clear tape on the front objective cover.”

Cheap But Effective — Tape on the Stock with Ballistics Data

Bryan Litz tape ballistics come-up hold-over

At the 2021 Nightforce ELR Steel Challenge, Applied Ballistics guru Bryan Litz wrote his come-ups on blue masking tape applied to his stock. He did this based on a tip from Chase Stroud. With the tape applied behind the action, the numbers are easily visible. This “cheap trick” does work apparently — Bryan won the match with a convincing victory over 220 other shooters. READ Match Report.

Cheap But NOT So Effective — Numbers on Hand

ballistics data hand come-up PRS NRL

Many of us have scribbled some come-ups on the back of a hand or on our forearm using a marking pen. That can work if you only have a couple distances to deal with — say 100 and 300 yards. But if you want a more complete Come-up table, get one of the card-holders shown above. Writing numbers on the skin is generally not such a good idea….

Sunday GunDay: Eliseo Tubegun in .308 Win — Great Palma Rig

Dennis Santiago Eliseo Competition Machine Tubegun Chassis .308 Win Rifle Berger Southwest Nationals

Our friend Dennis Santiago is a talented Service Rifle shooter, who regularly competes with an AR shooting the .223 Rem cartridge. A few seasons back, he decided to go over to the “dark side”, putting together a Palma (fullbore) rifle chambered for the .308 Winchester. Dennis selected a Competition Machine (Gary Eliseo) R1 Chassis for the project. Here’s Santiago’s account of his “true blue” Palma build.

Palma Rifle Report by Dennis Santiago
“This project was a .308 Win Palma rifle with an Eliseo R1 chassis, Rem 700 action (blue-printed with PT&G upgrades), Jewell trigger, Boots Obermeyer 1:11″-twist barrel, and Phoenix sights holding Gehmann apertures. Next comes chassis and sling set-up, initial mechanical zeroing, and load development. Yup, I have a bunch of Peterson small primer .308 brass, Sierra #2156 155gr MKs, and Varget to get started with. I’m told I can drive 155gr pills to stay supersonic to 1K. Should make for an interesting 2020. My goal was to be cozy with this blue beast by the time the Berger Southwest Nationals kicked off in February 2020.”

Pinning the Picatinny — For a Super-Solid Mount
Dennis Santiago Eliseo Competition Machine Tubegun Chassis .308 Win Rifle Berger Southwest Nationals

One of the key parts of the build, Dennis explains, is mounting the top rail with pins: “Once the rail is aligned using a spin-centered optic, it locks down with three 3/16″ roll pins. That way there is no reliance on screws that can come loose. Above is a photo of the top of the Eliseo tube chassis showing the three, 3/16″ roll pins that unitize the Picatinny rail. You can also see the four brass screws that just kiss the action to fully stabilize it in the tube. The recoil ring buttresses completely around the action with metal to metal contact. There are a million details hidden inside a Gary gun.”

Phoenix Sights Front and Rear

Rise of the Phoenix — Here are the sights for the Eliseo R1. There are very few manufacturers left making these kinds of ultra-precise and repeatable iron sights.

These Ray-Vin tools help set mechanical zero on the sights. Dennis notes: “Finally a reason to pull out the Ray-Vin calibration paraphernalia to set up a mechanical zero. This photo is for all of you who still remember that those barrel flats and screws in our sight towers actually had a purpose once upon a time.”

Sling ‘N Irons — Classic Palma Configuration
Dennis Santiago Eliseo Competition Machine Tubegun Chassis .308 Win Rifle Berger Southwest Nationals
Dennis plans to use an Eric Hollis sling with his new blue Palma rifle.

Peterson Small Primer .308 Win Brass for Santiago’s Rig
Berger southwest SW Nationals

Dennis has used Peterson Cartridge Small Rifle primer .308 Win brass. Peterson offers a “Select” version weight-sorted and length-sorted at the factory. All Select casings (in a 50ct box) are guaranteed to be within 1 grain in weight and .001″ in OAL. Peterson Select brass is available for 20 different cartridge types, including .308 Win both small primer/small flash hole and large primer/large flash hole.

Now Adapted with a Scope
Currently (in 2025) Dennis has this rifle fitted with a high-magnification Nightforce zoom scope, and he competes with his blue prone rifle in the “Any-Any” division. He usually runs the scope at about 22X power. For an older guy with aging eyes, being able to run high-magnification optics is a big plus.

With the optics Dennis has found the rifle to be exceptionally accurate. Shooting 168gr bullets it has produced 5-round groups around 1/3-MOA during testing. And it can easily hold the X-Ring at 300 yards.

Getting the Blue Rifle Ready for the Berger SW Nationals

Berger southwest SW Nationals

Dennis has campaigned his rifle at recent Berger Southwest Nationals (SWN) events. At the SWN a Palma shooter can shoot iron sights, or also fit a scope and shoot in the “Any Sights” category. The week-long Berger SWN is the biggest rifle match in the Western United States. Hundreds of shooters compete in both individual and team events. The SWN begins with the Mid-Range Nationals at 600 yards. Then the Long-Range matches are held, with targets out to 1000 yards. Watch the video to see the Ben Avery facility, home of the Berger SWN:

Features of a Quality Safe under $1000

Even if you already have a safe, this video is well worth watching. The host shows a variety of accessories and upgrades that all gun safe owners should consider. The host explains why you should have a dehumidifier or Golden Rod. He also shows how to install handy interior lights that activate automatically when the door is opened.

The Gun Vault — The Next Step Beyond a Jumbo Gun Safe

If you have a very large gun collection and are building a new custom home, you may want to consider a Gun Vault. This is essentially a large, secure room, with a very heavy door and thick walls. In this interesting video, Atlas builds a large walk-in gun vault using the Gallow Tech Shelving System and a Fort Knox Gun Vault door.

After the Fire — What Actually Happens in a Burned Safe

In this video, the hosts open a “fireproof” gun safe that went through an actual house fire. See what happens when a gun safe that is supposed to be fireproof actually is exposed to a major fire. The results are surprising to say the least. This video shows that you need to do your homework before buying a “fireproof” safe. Understand how the fire rating systems work, and learn how the interior materials and construction make a big different in real world fire protection.

Mechanical Locks vs. Electronic Locks — What You Need to Know

One important decision when buying a gun safe is the choice of locking mechanism. Should you go with a mechanical lock or an electronic lock? There are pros and cons to both dial locks and e-locks, and as long as you get a quality lock, neither is a bad choice. To help you make your decision, This video explains the differences between the two, and reasons why you might choose one over the other.

How to Assemble a Modular Safe with Simple Tools

For gun owners who move frequently, or who may live in an upstairs apartment or condo, a modular safe makes sense. Steelhead Outdoors, based in Minnesota, offers three different safes: Nomad 26, 32, and Nomad 38. The video below shows how to assemble a Steelhead Outdoors Nomad series safe. If you have basic skills, these safes can be assembled easily in 60-90 minutes. Steelhead recommends having two people to do the job. The entire safe ships in four (4) boxes. Wrenches are included with the safe.

This time-lapse video shows the entire process of assembling the safe, start to finish.

Guide to Quick Access Handgun Safes

A quick access safe can keep your pistol secure, but also readily accessible. But not all of these devices are created equal. This video explains the features you need in a small pistol safe. The video also examines the pros and cons of seven different handgun safes. We recommend that you do NOT keep your handgun safe in plain view, such as on a bedside table. There are other locations where you still have quick access, without tempting home intruders.

Wireless Hygrometer Reports Temperature and Humidity Inside Safes

The Hornady Security® Wireless Hygrometer monitors temperature and humidity in real-time, all without opening the gun safe. The wireless hygrometer employs a remote sensor inside your safe, which measures temperature and humidity data. This data is then sent to an external base display. Wireless technology eliminates the need to open the safe and check the storage environment, preventing temperature and humidity spikes from the outside air.

The display features a large touchscreen that shows current high/low data from both the base and remote units in Fahrenheit or Celsius. The hygrometer pairs with Hornady Security’s in-safe dehumidifiers to combat oxidation-causing moisture.

Gun Safe Installation Recommendations

Every safe, when possible, should be anchored in place with heavy-duty fasteners. Ideally, use multiple bolts in the bottom of the safe, anchored to concrete or solid foundation. Choose the appropriate lag bolts or anchors for the material below your safe. If you can’t mount to the floor, bolt the safe to wall studs. You can locate the position of the studs with an inexpensive electronic “Stud Sensor” available at home supply stores.

Check the thickness of your safe floor. If the steel on the bottom of your safe is fairly thin, place a steel backing strip between the bolt heads and the safe bottom. (Large washers will work, but a backing strip is better.) Without such reinforcement, the bolt heads may pull right through thin-gauge steel if the safe is rocked, or levered from the bottom with a pry-bar.

Locate your safe in the corner of a room or in a recess that blocks access to one or more sides of the safe. On many gun safes, the steel on the top, sides, and rear is thinner than on the door. Blocking access to the sides makes it much more difficult to use power tools on the sides, where the safe is most vulnerable. It’s also wise to place the safe in a relatively tight space with limited room to maneuver. Anything that makes the safe harder to move helps deter would-be thieves.

Many people place their safe in a garage or basement. That’s not necessarily a bad idea, but people also tend to store their tools in the same locations. Don’t store your power tools next to the safe. One safe-maker told us how a customer’s safe was defeated using the owners’ own cutting torch which was stored right next to the safe!

Inspect the area around the safe. Avoid locations where there are a lot of wood beams, paint cans, or other combustible material nearby. In the event of a serious house-fire, these items will fuel the flames, increasing the likelihood that items inside your safe will be heat-damaged. Chris Luchini, co-author of Rec.Gun’s Guide to Gun Safes, offers some practical advice: “Get an alarm system. If the burglars hear an alarm go off, they are less likely to stick round to finish the job. Alarms on both the house and the safe area are a good idea.”

Mantis Dry-Fire Products for Winter Indoor Training

mantis X10 pistol rifle ar ar15 training tracking system

This winter there has been very cold weather throughout much of the USA. For many marksmen winter indoor training is needed if they want to maintain their shooting skills. Even if you can shoot outdoors all year long in your location, it makes sense for position shooters to work on their rifle holds. The Mantis systems help with that. These advanced smart devices record and plot the movement of your firearm as you aim and then break the shot. There are systems for both dry-fire and live-fire training, starting at $99.99. Considering the cost of bullets these days, and the difficulty of finding primers, it makes sense to increase your dry-fire training.

Mantis X2 for Dry-Fire, $99.99

Built for dry-fire use only, the Mantis X2 ($99.99) provides real-time, shot-by-shot feedback for both pistol and rifle users. You can track multiple training sessions with data-driven insights, and monitor your progress. This unit has earned high user reviews such as: “As a new gun owner the Mantis X is a game changer for me. I have not been able to get to the range during the lockdowns and being able to practice at home [is great].” And another: “Easy to install[.] The App is free and easy to use.”

The Mantis X2 is a good value. The manufacturer states: “There is nothing at this price point that will give you this level of feedback for dry fire.” There are actually four Mantis models: X2 ($99.99), X3 ($169.99), X7 Shotgun ($199.99) and X10 Elite ($249.99). The X3 adds live fire functionality. MORE INFO HERE.

Mantis X10 Elite– Advanced Training System

The advanced Mantis X10 Elite ($249.99) is 50% lighter and 40% smaller than the original Mantis, with three times the battery life and four times the data transfer rate. This new quick-detach X10 system offers all X2 and X3 functions PLUS recoil analysis and software support for all shooting sports (pistol, rifle, shotgun, archery). Collecting thousands of data points per second, the X10 works with dry fire, live fire, airsoft/CO2, and simulated firearm systems.

Mantis Blackbeard Trigger Reset System for AR-Platform Rifles

Using electromechanical wizardry, the $199.00 Blackbeard quickly resets the hammer between each shot, so you can stay in position through multiple practice shots. Installation takes less than a minute — remove the bolt carrier group, drop in the red upper unit, place the red Mantis magazine and you’re good to go. All Blackbeards now support both direct impingement and piston-driven ARs. Guys we know say that a few sessions with this system delivered marked improvement in their service rifle scores.

Mantis X3 for Live-Fire or Dry-Fire, Rifle and Pistol

The Mantis X3 collects thousands of data points per second and analyzes your shooting in real-time. For both pistols and rifles, the X3 works with dry fire and live fire. It will also work with airsoft/CO2/compressed air, and simulated firearm systems. Priced at $169.99, the Mantis X3 mounts to standard universal accessory rails. (No Picatinny rail?

F-Class Front Rests Reviewed

This is a great summary of multiple quality front rests. This is a must-watch video for all F-Open and Benchrest shooters! If you are shopping for a front rest, definitely watch this comprehensive 42-minute video from start to finish. This is probably the most informative video about premium shooting rests available on YouTube. Top F-Class shooter and video-maker F-Class John covers a wide selection of front rests, with some observations about coaxial bipods as well. John covers the impressive new SEB NEO-X, the easy-to-transport SEB Mini-X, the excellent Rodzilla Rest, the innovative 21st Century Hybrid Rest, the sleek Italian Lenzi Rest. At the end of the video John reviews the very affordable Caldwell Fire Control Rest ($269.99 at MidwayUSA), explaining how it can be a decent choice for shooters on a limited budget.

How to Use a Barrel Tuner to Improve Accuracy and Repeatability

Erik cortina e.c. Tunner f-class john videosIn this video, John works with a barrel tuner created by Erik Cortina, a member of Team Lapua/Brux/Borden. A tuner can be useful in modulating barrel vibrations and that can translate to smaller groups on target. Sometimes the positive effects are quite noticeable. Tuners have been popular with short-range benchresters for many years and now they are becoming more common on top F-Class and Long Range rifles.

John says: “I’ve been using Erik’s E.C. Tuner for a while now and I really like what it’s done to help as my final step in load development. Just remember, a tuner is a tool, not a magician. You still need good load development practices, good brass prep, and solid skills but the tuner does help make great loads even better.”

F-Class Rear Bag Setup: Fill Techniques for Ultimate Consistency

In this helpful video, F-Class John shows his process for filling high-quality Dima rear bags (both medium models). John explains how to select fill (based on weight and density preferences). He shows the different funnel systems that work very effectively. If you’re planning to invest in a quality rear bag for competition, this video will be useful, both in choosing appropriate fills and getting the fills into the bag efficiently.

21st Century Hydro Press and Arbor Press — Product Review

Many of the world’s top benchrest, long-range, and F-Class shooters prefer to seat their bullets using arbor-type presses with inline dies. This allows smooth, repeatable bullet-seating with very low run-out. One of the very best arbor-type seating presses ever created is the 21st Century Hydro Press. This offers plenty of leverage driving a precision ram. The Hydro Press also features a hydraulic line to drive a precision seating force gauge. Along with the Hydro Press, John tests 21st Century’s standard arbor press.

Accuracy One Concentricity Gauge — Product review

Every person who makes precision hand-loads should have a quality concentricity gauge to measure run-out of case-necks and loaded rounds. Here John tests one of the best such tools on the market, the Accuracy One Concentricity Gauge. This measures the internal and external neck runout of cartridge cases as well as seated bullet runout. It can also measure the runout of the ogive, bearing surface, and boat-tail of individual bullets and can even measure primer pocket runout. John notes: “I think most precision shooters should have one of these to make sure their ammo is within their specs they’re happy with.”

Henderson vs. Giraud Rifle Power Brass Trimmer Review

After adding the impressive Henderson Gen 3 Powered Trimmer to his inventory of tools. F-Class John became is a Henderson fan. He likes the speed, precision, and repeatability of the $439.00 Henderson machine, which trims-to-length and chamfers the case mouth all in one pass. Unlike some other trimming tools, the Henderson indexes off the overall case length NOT the shoulder. The $575.00 Giraud trimmer is a very different design which indexes off the case shoulder, but it is also very precise. When set up correctly, it can trim brass with amazing consistency. As long as you have fire-formed brass with consistent base-to-shoulder dimensions, you should get very consistent trim lengths.

SuperTrickler vs. AutoTrickler V4 Powder Measure Comparison

This video compares the elite SuperTrickler and AutoTrickler V4. The AutoTrickler system paired with a quality Force Restoration scale, is the “Rolls Royce” of electronic powder dispensing systems, offering unrivaled charge-weight accuracy, great repeatability, and ultra-fast dispensing speeds. If you have the budget — $490 for the V4 plus $720+ for A&D FX-120i scale — the AutoTrickler V4 is a superb system that lets you load extremely accurate, consistent ammo. This detailed F-Class John video compares the AutoTrickler with and all-in-one SuperTrickler scale/dispenser which also performs great. The SuperTrickler ST101 is $775.00 for ST101 Gen2 top unit only or the full unit is $1400.00 complete with FZ-120i scale.

Teslong Rigid 26″ Borescope with 4.5″ Monitor — Product Review

There are a variety of affordable Teslong digital borescopes for inspecting your barrels and diagnosing issues. All Teslongs deliver impressively sharp images/video. Some units plug into a laptop or tablet, while others work via a dongle to communicate wirelessly. Here John tests a 26″ rigid model borescope that comes complete with its own 4.5″ viewing screen. Priced at $149.99 on Amazon, this system is completely self-contained — you don’t need a laptop or smartphone. You don’t have to worry about connections and there are no Apps to install or configure. John says: “Teslong now offers a 26″ rigid rod model with a 4.5″ monitor. This allows you to use the unit without the need for any mobile device or computer.”
