The question of barrel break-in is controversial. Some folks advocate an elaborate, lengthy cycle of shooting and brushing, repeated many times — one shot and clean, two shots and clean and so on. This, it is argued, helps barrels foul less and shoot more accurately. Others say minimal break-in, with patching and brushing after 10-15 rounds, is all you need. Still others contend that break-in procedures are a total waste of time and ammo — you should just load and shoot, and clean as you would normally.
We doubt if there will ever be real agreement among shooters concerning barrel break-in procedures. And one must remember that the appropriate break-in procedure might be quite different for a factory barrel vs. a custom hand-lapped barrel. This Editor has found that his very best custom barrels shot great right from the start, with no special break-in, other than wet patches at 5, 10, and 15 rounds. That said, I’ve seen some factory barrels that seemed to benefit from more elaborate break-in rituals.
What’s the best barrel break-in procedure? Well our friend Eric Mayer of Varminter.com decided to ask the experts. A while back Eric interviewed representatives of three leading barrel manufacturers: Krieger, Lothar-Walther, and Shilen. He recorded their responses on video. In order of appearance in the video, the three experts are:
Do I Need to Break-In a New Rifle Barrel?
Eric Mayer of Varminter.com says: “That is a simple question, [but it] does not necessarily have a simple answer. Instead of me repeating my own beliefs, and practices, on breaking-in a new rifle barrel, I decided to answer this one a bit differently. While we were at the 2016 SHOT Show, we tracked down three of the biggest, and most popular, custom barrel makers in the world, and asked them what they recommend to anyone buying their barrels, and why they recommend those procedures. We asked the question, and let the camera run!” Launch the video above to hear the answers — some of which may surprise you.
Long-Term Barrel Care — More Experts Offer Opinions
Apart from the debate about barrel break-in, there is the bigger question of how should you clean and maintain a barrel during its useful life. Some folks like aggressive brushing, other shooters have had success with less invasive methods, using bore foam and wet patches for the most part. Different strokes for different folks, as they say. In reality, there may not be one solution for every barrel. 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).
“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.” — Chip Lohman

Forest of Windflags at World Benchrest Championships in France in 2011
There’s a simple, inexpensive “miracle device” that can cut your groups in half. If you’re not using this device, you’re giving away accuracy. The “miracle device” to which we refer is a simple wind indicator aka “windflag”. Using windflags may actually improve your accuracy on target much more than weighing charges to the kernel, or spending your life savings on the “latest and greatest” hardware.
Remarkably, many shooters who spend $3000.00 or more on a precision rifle never bother to set up windflags, or even simple wood stakes with some ribbon to show the wind. Whether you’re a competitive shooter, a varminter, or someone who just likes to punch small groups, you should always take a set of windflags (or some kind of wind indicators) when you head to the range or the prairie dog fields. And yes, if you pay attention to your windflags, you can easily cut your group sizes in half. Here’s proof…
Miss a 5 mph Shift and You Could DOUBLE Your Group Size
The table below records the effect of a 5 mph crosswind at 100, 200, and 300 yards. You may be thinking, “well, I’d never miss a 5 mph let-off.” Consider this — if a gentle 2.5 mph breeze switches from 3 o’clock (R to L) to 9 o’clock (L to R), you’ve just missed a 5 mph net change. What will that do to your group? Look at the table to find out.
Values from Point Blank Ballistics software for 500′ elevation and 70° temperature.
Imagine you have a 6mm rifle that shoots half-MOA consistently in no-wind conditions. What happens if you miss a 5 mph shift (the equivalent of a full reversal of a 2.5 mph crosswind)? Well, if you’re shooting a 68gr flatbase bullet, your shot is going to move about 0.49″ at 100 yards, nearly doubling your group size. With a 105gr VLD, the bullet moves 0.28″ … not as much to be sure, but still enough to ruin a nice small group. What about an AR15, shooting 55-grainers at 3300 fps? Well, if you miss that same 5 mph shift, your low-BC bullet moves 0.68″. That pushes a half-inch group well past an inch. If you had a half-MOA capable AR, now it’s shooting worse than 1 MOA. And, as you might expect, the wind effects at 200 and 300 yards are even more dramatic. If you miss a 5 mph, full-value wind change, your 300-yard group could easily expand by 2.5″ or more.
If you’ve already invested in an accurate rifle with a good barrel, you are “throwing away” accuracy if you shoot without wind flags. You can spend a ton of money on fancy shooting accessories (such as expensive front rests and spotting scopes) but, dollar for dollar, nothing will potentially improve your shooting as much as a good set of windflags, used religiously.
New Wind Reading App — High Power Wind Lab
There is an innovative new Wind-Reading App, the High Power Wind Lab, that can help you figure your hold-offs in all wind conditions. This is available now for iOS devices, and an Android version is coming soon. In this video, our friend F-Class John reviews this sophisticated new Wind App:
Lyman’s popular Case Length Gauge is now bigger and better. The enhanced version II of Lyman’s Case Length Gauge is much larger than the original version. The E-Zee Case Gauge II now measures more than 70 cartridge types — way more than before. This tool is a metal template with SAAMI-max-length slots for various cartridge types, including relatively new cartridges such as the .204 Ruger and Winchester Short Magnums. This tool allows you to quickly sort brass or check the dimensions. If you have a bucketful of mixed pistol brass this can save you hours of tedious work with calipers. You can also quickly check case lengths to see if it’s time to trim your fired brass.
If you load a wide variety of calibers, or do a lot of pistol shooting, we think you should pick up one of these Lyman Case Gauge templates. They are available for under $26.00 at Brownells ($24.99) and Amazon.com ($19.39). The E-Zee Case Gauge has long been a popular item for hand-loaders.
NOTE: For years the E-Zee Case Gauge had a silver finish with black lettering, as shown in the video. Some of the most recent production of E-Zee Case Gauges have a new “high contrast” look, with white lettering on a black frame. You may get either Case Gauge version when you order online (Brownells shows silver, Amazon shows black). We actually prefer the older, silver version.
Case Gauge Should Last a Lifetime
Easily measure the case length of over 70 popular rifle and pistol cases with Lyman’s new E-Zee Case Length Gauge II. This really is a “must-have” piece of kit for any gun owner who hand-loads numerous pistol and rifle calibers.
This rugged, precisely-made metal gauge makes sorting or identifying cases fast and accurate. The template is machined with SAAMI max recommended case lengths. Made from metal, with no moving parts, the E-Zee Case Gauge II should last a lifetime.

With the Whidden Click-Adjustable Sizer Dies, you can change shoulder bump by .001″ (one-thousandth) with a simple click. Fast. Easy. Precise.
As handloaders have become more aware of shoulder bump and proper adjustment of the sizer die in recent years, there has become a need for an easier way to adjust the sizer die properly. For most folks, with their conventional dies, it takes lengthy trial trial and error to get the shoulder setback correct. Anyone who has done this can attest that it can be a slow and annoying job.
Whidden Gunworks has solved the problem with the innovative Click Adjustable Sizer Die. Patent No: 10,393,488. This die and lock ring work together to give the user a clicking feel to the adjustment just like a high end rifle scope. Each click moves the shoulder bump exactly .001″ so you can easily find the exact shoulder bump that you desire.
The Click Adjustable option is available on Whidden Custom Sizer dies as well (7/8”-14 format dies only)! Included with the Click Adjustable Sizer Die is a Shoulder Bump Gauge. This gauge attaches to standard calipers and allows measurement from the case shoulder to the base. Using the Shoulder Bump Gauge with the Click Adjustable Sizer Die will make the proper sizer die setup easier than ever before.
Click-adjustable die sets are available with both bushing and non-bushing configurations. Along with these complete die sets, Whidden Gunworks offers a separate click-adjustable ring to use with existing dies. Priced at $54.95, the Whidden Click-Adjust Lock Ring represents a modest investment for a major gain in die ease-of-use and precision adjustability.
The Whidden Universal Click Adjustable Lock Ring you can instantly turn your sizer die into a Click Adjustable Die. This ring works with any 7/8 OD sizer of any brand with adjustable shoulder bump. Simple in design, the inner and outer ring can rotate independently of each other. Each click is metered in true 1 thousandths adjustment and has 0.100″ total available travel. These work great with nearly all sizing 7/8 OD sizing dies, and one verified purchaser noted: “Not only are they useful on reloading dies, but it’s the cat’s meow on the Giraud Power Trimmer Case Holders.”
Dillon Users Take Note: The Whidden Click Adjustable Sizing Die will not work with the Dillon 550 or 650 progressive reloading press systems. The Universal Click Adjustable Lock Ring is not compatible with the Dillon floating toolhead.

The .17 Winchester Super Magnum (aka .17 WSM) is the fastest, flattest-shooting rimfire cartridge ever created. The .17 WSM cartridge, as you can see below, is significantly larger than the .17 HMR, and can deliver a 3000-fps muzzle velocity with a 20gr bullet, compared to about 2375 fps for .17 HMR 20gr ammo. That’s 26% more speed, which translates to a much flatter trajectory — a big deal when you’re shooting small varmints out to 300 yards.
The .17 WSM has been around for a while, but there have been limited selections of rifles chambered for this speedy rimfire round. Savage is changing that. Savage just announced that it will offer its A17-series rifles chambered in .17 WSM. Currently choose from two models with laminated wood stocks: the A17 WSM Sporter and A17 WSM Target Thumbhole. Both rifles feature a delayed-blowback, semi-automatic action specifically designed for the 17 HMR and 17 WSM cartridges. And both rifles boast 22″ button-rifled barrels, user-adjustable AccuTriggers, and 10-round rotary-feed internal magazines.
Between the two, the Target Thumbhole model ($709 MSRP) would be our choice for varmint work, as the stock has nice ergonomics and shoots better off the bags, with a thicker, wider forearm. The A17 WSM Target Thumbhole model also has a 22″ fluted heavy target barrel. This is better for high-volume varmint sessions than the standard-contour barrel on the Sporter model ($619 MSRP).
Savage Action Should Work Well with the .17 WSM Cartridge
Savage is proud of its new .17 WSM rifles: “We are launching the A17 chambered for .17 WSM in two of our more popular configurations [with laminate stocks]. Both are designed for target shooting and varmint hunting applications[.] The new A17 WSM Sporter and A17 WSM Target Thumbhole pair the dynamic rimfire cartridge with Savage’s A Series semi-automatic action for exceptional accuracy and fast follow-up shots.”
“Savage has seen outstanding performance from the .17 WSM cartridge and felt it could be optimized in new platforms. The A Series rifles have a delayed blowback design that accommodates this caliber with limited modifications, making it an ideal action for the WSM cartridge.” — Jessica Treglia, Savage Arms Senior Brand Manager.
A17 WSM Target Thumbhole Features
Gray wood-laminate thumbhole stock

Commentary — This Could be a Great Varmint Option, IF the Ammo Becomes Available
If we were in the market for a new rifle for serious, high-volume ground squirrel and prairie dog varmint safaris, we would seriously consider this new A17 in .17 WSM. With a rimfire cartridge you don’t have to bother with handloading. And you should enjoy significantly better barrel life than a larger centerfire cartridge burning much more powder — provided you don’t shoot too fast and over-heat your barrel. Also, you won’t struggle to find primers. However, unfortunately .17 WSM ammo is hard to find right now, as we explain below. Be aware of the ammo shortage issue.

New 3000 FPS Rimfire Round
A few years back Winchester created a high-velocity 17-caliber rimfire cartridge, the .17 Winchester Super Magnum (aka .17 WSM). Winchester has offered .17 WSM ammo with a choice of three bullet types: 20gr plastic tip (Varmint HV), 25gr plastic tip (Varmint HE), and a 20gr JHP (Super-X). The 20-grain varieties boast a 3000 FPS muzzle velocity, earning honors as the fastest Rimfire ammo ever made.

Winchester claims that all .17 WSM ammo types shoot much flatter than the .22 Win Mag and .17 HMR, while delivering 150 percent more energy than both. In addition, the .17 WSM “bucks the wind” better than any other rimfire ammo — exhibiting significant less horizontal drift at extended ranges.

.17 WSM Ammunition is “Unobtanium” Right Now
Since its introduction, .17 WSM ammo has been sold by multiple companies including Browning, Federal (American Eagle), Hornady, and Winchester. Right now it is very hard to find ANY .17 WSM ammo. You have to look far and wide. On January 9, 2022 we checked with five major online vendors and found no .17 WSM ammunition in stock at Midsouth, MidwayUSA, Natchez, Precision Reloading, and Locked&Loaded. Every variety was listed as “Out of Stock” or “Temporarily Unavailable”. That’s discouraging. Hopefully more .17 WSM ammo will be appearing on dealer’s shelves in the months ahead.

The .375 EnABELR cartridge was developed to offer magazine-feeding capabilities with the highest-BC solid bullets available. The .375 EnABELR cartridge is slightly shorter than a .375 CheyTac so it allows the round to mag-feed. Applied Ballistics is currently using brass made by Peterson. The .375 EnABELR has achieved impressive velocities — 2990 FPS — with prototype Berger 379-grain solid bullets fired from a 1:7″-twist 30″ barrel. Applied Ballistics may also test 1:8″-twist and 1:9″-twist barrels. READ Bullet Testing Report.
The .375 EnABELR cartridge was designed to offer .375 CheyTac performance in a slightly shorter package: “The problem with the .375 CheyTac is that, when loaded with the highest performance .375 caliber bullets (379-407 gr Berger Solids, and the 400-425 grain Cutting Edge Lazers) the round is not magazine feed-able in any action that’s sized for CheyTac cartridges.
Here is Mitchell Fitzpatrick, shooting the 375 EnABELR in an ELR Competition.
“Knowing the .375 CheyTac produced substantial performance, and that it was just too long for magazine feeding, made it easy to converge on a design for the .375 EnABELR. We just had to make the case short enough to achieve magazine length with the desired bullets, while adding a little more diameter to keep the case capacity similar to the .375 CheyTac. The resulting basic shape is quite similar in proportions to the successful .338 Norma Magnum Cartridge which, interestingly, was selected as the cartridge for General Dynamics Lightweight Medium Machine Gun (LWMMG).”

Before you load that nice new cartridge brass for the first time, run an expander mandrel down the case necks. This will iron out dents and provide more uniform neck tension. Chose a mandrel diameter that provides appropriate neck tension.
Lapua brass is so good that you’ll be tempted to just load and shoot, if you have a “no-turn” chamber. However, some minimal case prep will ensure more uniform neck tension. Keeping your neck tension very uniform allows more consistent bullet seating. That, in turn, usually yields better accuracy, and lower Extreme Spread and Standard Deviation (ES/SD). Lapua brass, particularly 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win comes from the factory with tighter-than-optimal necks. Before you seat bullets, at a minimum, you should inside chamfer the case mouths, after running an expander mandrel down the necks. The expander mandrels from both Sinclair Int’l and K&M will both leave the necks with enough neck tension (more than .001″) so you can then seat bullets without another operation. We suggest putting a bit of lube on the mandrel before running it down the necks — but remove any lube that gets inside the necks before seating bullets.
Both Sinclair and K&M Tools make a die body specifically to hold expander mandrels. The Sinclair version, is shown above. This $32.99 unit fits caliber-specific expander mandrels ($9.99) which measure approximately .001″ less than bullet diameter for each caliber. This is an updated “Gen II” design that completely captures the mandrel within the die so the mandrel cannot pull out. It also has an O-ring in the die cap that allows the mandrel to self-center within the case neck. Sinclair now offers three sizes of die bodies for expander mandrels: .17 -.338 Caliber (#749-011-715WS); .357 – .50 caliber (#749-008-843WS), and a special .50 Cal die body for large-diameter 50 BMG presses (#749-009-163WS, $39.99). All Generation II dies are machined from stainless steel and the standard diameter 7/8-14 dies include the Sinclair Stainless Steel Split Lock Ring.
Once you run the Sinclair expander mandrel down the necks of Lapua brass, after you account for brass spring-back, you’ll have about .002″ neck tension*. This will make the process of seating bullets go much more smoothly, and you will also iron out any dents in the case mouths. Once the case mouths are all expanded, and uniformly round, then do your inside neck chamfering/deburring. The same expander mandrels can be used to “neck-up” smaller diameter brass, or prepare brass for neck-turning.
Forum member Mike Crawford adds: “These expanders can also reduce runout from offset seating. Prior to bullet seating, expand the sized necks to force thickness variance outward. With the Sinclair system, the necks will springback fine, and will not be pulled out of center. This leaves plenty of tension, and bullets seated more centered. I do this, even with turned necks, to get improved seating.”
Mandrels vs. Expander Balls on Decapping Rods
If you haven’t acquired an appropriate expander mandrel for your brass, but you DO have a full-length sizing die with an expander ball, this will also function to “iron out” the necks and reduce tension. However, using a die with an expander ball will work the necks more — since you first size them down, then the ball expands them up again. Typically (but not always), run-out is worse when using an expander ball vs. an expander mandrel.
* This .002″ tension is what we have observed with Lapua 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win brass. This might vary with much smaller or larger cases, and of course a different brand of brass might yield different results. If you get too little tension with your current mandrel, you can get a smaller-diameter mandrel from 21st Century Shooting. 21st Century even offers low-friction Titanium Nitride-coated mandrels.

Reading the Wind — How to Determine Wind Speed
Keith Glasscock is a top-tier F-Class shooter who has finished second at the F-Class Nationals multiple times. Keith is also a highly-respected wind coach with a background in commercial aviation — so he really understands wind and weather. In this video Keith explains the best techniques for reading the speed of the wind. He notes that you can’t simply rely on the Kestrel in your hand because the wind speed can vary significantly between the firing line and the targets. Keith shows how to look at multiple signs (including flags, grass movement, and mirage) to better understand wind velocity. See more of Keith’s videos on his Winning in the Wind YouTube channel.

If the battery on your safe’s electronic lock is more than a year old, or if it is not giving you the right voltage, replace it today!
Well it’s a New Year folks — 2022 is here, so change those Gun Safe Keypad Batteries!
By this time, many of our readers have stashed their guns away in the safe for the remainder of the winter. It’s easy to just tuck the guns away and forget about them. But there’s something you should do before you shut the safe door. If you have a safe with an electronic keypad, you should replace the battery every year as a precautionary measure. Trust us, you don’t want to come back in a few months and find that the keypad memory is kaput, and you’re locked out. That can lead to frustration and an expensive locksmith visit.
Here’s a true story. I have one safe with a Sargent & Greenleaf (S&G) keypad. A couple years back, in early December, I went to get into the safe. I punched in the correct combination, but all I got was a rapid “beep, beep, beep, beep” after I finished the last combination entry. I tried again to ensure I entered the combination correctly (I did). But again, the locking system responded with multiple rapid beeps indicating something was wrong. And the safe would not open. Now I was worried….
I popped out the battery holder (which slides in from the bottom of the keypad housing on the door). I removed the battery and tested it with a volt-meter. The 12-month-old Duracell 9-volt battery only registered 6.1 volts.
Low voltage was the problem. I went down to the store and got a couple new 9V batteries. I tested the new batteries and both measured 9.4 volts output. I slipped one of the new 9V batteries into the keypad housing, punched in the combination and everything worked OK again. Eureka.
Most electronic locks for safes WILL “remember” the combination for a period of time even when the battery is low (and the keypad’s “brain” should retain the combination when you remove the battery for replacement). However, a dead battery, or extended periods of low voltage can give you problems. Don’t rely on wishful thinking…

A while back, our friend Vince Bottomley in the UK wrote an excellent article for Target Shooter Magazine. Vince offers “solid-gold” advice for new F-TR and F-Open shooters. Vince reviews the cartridge options, and offers suggestions for a shooter’s first (and hopefully affordable) F-Class rifle. Vince also reviews various bipod choices for F-TR and discusses optics options (from $300 to $3000).
Getting Started in F-Class by Vince Bottomley
As membership secretary of a large club, one of the questions I’m frequently asked – “What’s the best way to get started in F-Class?” My club has an F-Class shoot every couple of weeks at ranges from 300 to 1000 yards and, not surprisingly, it’s very popular.
F-TR or Open Class?
From a shaky start way back in 2004, the F-TR Class is now proving as popular as Open Class and, at GBFCA League shoots and club shoots, many shooters choose to start with a 308, shooting off a bi-pod – in other words F-TR. In Open Class, the 7mm WSM soon established itself as the “must have” cartridge – if you wanted to win but, the WSM’s appetite for barrels eventually brought another 7mm cartridge into play – the 284 Winchester. This 50-year-old stalwart was revived a decade or so ago as the 6.5-284 and indeed this cartridge found some favor with F-Class pioneers – before the potency of the WSM was discovered. If you don’t mind shelling out for a couple of barrels per year (barrel life is about 750 rounds with the WSM) go for the 7mm WSM but, if you require a decent round-count, then opt for the .284 Win and learn to read the wind a bit better!

Scopes for F-Class
If you will be shooting 1000 yards then I would recommend at least 32 power and preferably a variable – like the 8-32. The cheapest “usable” scope in this range is the Sightron 8-32x56mm SIII. It’s a great scope for the money and at under $1000 (in the USA) it’s half the price of some of its competitors. It’s also light – at 1.5 lbs – and there are some great reticles for the F-Class shooter – like the LRMOA.
Do I Need to Break-In a New Rifle Barrel?
There’s a simple, inexpensive “miracle device” that can cut your groups in half. If you’re not using this device, you’re giving away accuracy. The “miracle device” to which we refer is a simple wind indicator aka “windflag”. Using windflags may actually improve your accuracy on target much more than weighing charges to the kernel, or spending your life savings on the “latest and greatest” hardware.
