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
In many states, schools have been closed and citizens have been ordered to stay at home for days or weeks, as a response to the Coronavirus health issue. With more gun owners at home with their kids for extended periods, firearms safety is more important than ever. Given that fact, the NSSF reminds gun owners to keep their guns locked up so they cannot be accessed by children.
The National Shooting Sports Foundation (NSSF) and its partners urge gun owners to keep firearm safety a top priority and are making safety resources widely available as gun and ammunition sales increase, especially among first-time firearm purchasers.
“During this stressful time and with children spending more time at home, the firearm industry reminds gun owners that protecting yourself and your family includes making sure your firearms are stored securely when not in use”, said Joe Bartozzi, NSSF President and CEO. “The last thing any firearm owner wants is to have their gun fall into the wrong hands, particularly those of a child or someone at risk of harming themselves.”
For anyone considering buying a gun, Project ChildSafe’s Road To Responsible Firearm OwnershipMany Paths to Firearm Safety video series helps gun owners determine the best safe storage device for their home/lifestyle. You also view the Safe Storage Options chart.
NSSF encourages gun owners and non-gun owners to use the firearm safety resources available on its Project ChildSafe website. These include the McGruff Gun Safety videos for young children and this educational video explaining how to discuss gun safety with children:
“More parents are assuming the role of educators in their homes, so it’s a good to time have a talk with your kids about gun safety, even if you don’t own a gun”, Bartozzi said. “If you do own a firearm, be sure your family understands the safety rules regarding firearms in your home, and always store guns responsibly when not in use.”
The Civilian Marksmanship Program (CMP) is closing all its facilities and halting all scheduled activities from Monday, 3/23/2020 through Monday, 4/6/2020. During this period the CMP recommended that all CMP match sponsors “cancel their matches until some degree of normalcy returns.” The CMP issued this statement today:
Greetings. Many are facing difficult times in regard to the recent Corona virus outbreak and the CMP community is among them. We are grappling with the status of many of our current and upcoming programs, and unfortunately several events will be canceled or altered as a result.
The federal government’s Centers for Disease Control and Prevention has proclaimed that all events with attendance of 50 or more should be canceled immediately. The CMP has complied with this directive and we are notifying customers and participants accordingly.
The CMP is shutting down all of its facilities and activities for the next two weeks, beginning Monday, March 23, with plans to return Monday, April 6. During that time, the CMP will monitor conditions and will report changes to that plan as required. CLICK HERE for additional closure information.
We encourage all CMP match sponsors to cancel their matches until some degree of normalcy returns. It is in the best interest of the CMP community to take positive precautions rather than deal with potentially damaging consequences otherwise.
The CMP thanks you for your understanding during these trying conditions. We look forward to greater times ahead and getting back to the business of firearms safety and marksmanship!
Savage Arms has completed a major overhaul of the Savage website. Now the SavageArms.com site is more mobile-friendly and easier to navigate. Savage has expanded information on its rifle products, and also updated the Expert Advice area. This section of the website offers informative technical articles/videos, as well as numerous helpful tips for hunters.
You’ll find 30 informative topics in the Expert Advice section of the updated Savage Arms website. Below are FIVE of our favorites. Click each item to view the full text and linked VIDEOS. Even if you don’t own a Savage, these features are useful. And all new shooters should definitely check out the Advanced Optics selection. This features a good video covering mirage and light refraction.
1. Advanced Optics — Stan Pate
Light refraction can wreak havoc on your ability to connect with a target at extreme long range. Stan Pate offers some good advice concerning mirage and refraction.
If you have been waiting to purchase a chronograph… now is a great time to buy. You can get the affordable MagnetoSpeed Sporter for under $158.00. You can set up this device in a few minutes, and you never have to go downrange to fiddle with a tripod or fuss with wires. The MagnetoSpeed Sporter is simple and effective — a no-hassle solution.
See MagnetoSpeed Sporter Chronograph Features Reviewed in Video
We like the Sporter chrono, as do other shooters — this unit is very popular. Like the MagnetoSpeed V3, the Sporter faithfully records shots, even in complete darkness. Shot strings are recorded digitally and can be transferred to a smart phone via MagnetoSpeed’s XFR accessory (and Apps).
The Magnetospeed Sporter offers most of the features of the more expensive models (see chart below for details) and has a updated sensor. MagnetoSpeed says its new Sporter is “Ideal for contoured rifle barrels (sporter barrels) and long-barreled revolvers.” The Sporter Chronograph Kit (shown above) includes: Bayonet Sensor, 3.5 foot Data Cable, Remote Display (with Battery), Strap with thumb nut, Two V-block spacers, and compact storage box.
Q: Will the Sporter Chrono work with thicker barrel (i.e. greater than 1″ diameter)?
A: The manufacturer recommends the $399.00 V3 model for thicker barrels. But, wink-wink, if you have a 1.25″ barrel you can get this to work, based on what we’ve seen.. If you have a really fat barrel (up to 2.0″ diameter), get the V3. Magnetospeed also says the V3 is needed for airguns, shotguns, and muzzleloaders.

The Sporter Chrono attaches quickly and easily. It has a 3.5-foot-long cord, and will work with Muzzle Brakes and Flash-hiders up to 2.7″ long.
When he measures his loads or sorts bullets by weight, Forum Member Boyd Allen often employs his trusty RCBS 10-10 balance beam scale (although he does have handy digital scales as well). He finds that the balance beam scale works predictably, time after time, and it doesn’t suffer from the drift and calibration issues that plague some of the less expensive electronic scales on the market.
To make it easier to see the balance point, Boyd has adapted a magnifying glass with a mirror. This makes the end of his balance beam easier to view from his normal position on the bench. Boyd explains: “This set-up uses a cheap magnifier with positioning arms that was probably designed to hold and magnify small objects while soldering them. I think that it came from Harbor Freight many years ago. The mirror lets you look at the scale as if is was at eye level, and of course the magnifier makes the image easier to see.”
This impressive 15-round group was shot by Jim See of Elite Accuracy.
Different Shooting Disciplines Demand Different Levels of Precision/Accuracy
In the rapid-fire 3-Gun game, you could probably “clean” most stages with a 2-MOA rifle. By contrast, in the short-range group benchrest game, to compete with the best, you’ll need a rifle that shoots in the “ones” (i.e. 0.1-0.19 MOA) in perfect conditions. In 1000-yard F-Class competition, the top shooters want a rifle that will hold one-third-MOA of vertical at that distance.
What is your standard of accuracy? How good is “good enough”. Jim See, a skilled gunsmith and successful PRS competitor, recently answered that question for his tactical discipline. For the kind of matches Jim shoots, he likes to have a rifle that will hold half-MOA for five (5) shots, 3/4-MOA for 15 shots, and 1 MOA for twenty shots. Remarkably, Jim’s rifle can do that with factory ammo. Above is an impressive 15-shot group shot with .260 Remington Federal Premium Ammo.
“I say it all the time, my loads need to print 5 under 1/2″, 10 under 3/4″, and 20 under 1″. It’s simple, if a hot barrel will keep 20 rounds fired in succession under my standard it will be a good barrel and load for Precision Match Shooting. Federal Premium Gold Metal Match .260 with Sierra bullets made the cut for me today. 15 consecutive shots under 3/4 MOA.” –Jim See
It’s said that you “can never have too much accuracy”, but there are acceptable standards for each discipline, and they’re not the same. A 100/200 yard Benchrest shooter will be sorely disappointed with a rifle/ammo set-up that can only deliver half-MOA. On the other hand, a PRS competitor like Jim See can achieve great success with a lesser degree of precision. This means you can save time and money. You can run your barrels longer between cleanings, and you don’t have to go “full OCD” when loading your ammo. The PRS shooter does not need to weigh-sort primers, or load powder to single-kernel standards. Proof is the performance. Jim See recently took third place at the Spearpoint Shootout, and he has been a podium finisher at other events. Learn more about Jim’s gunsmithing and training operations at EliteAccuracy.com.
Download This Load Development Target
Jim’s target seemed a bit familiar. AccurateShooter.com created this Diamond and Dot Target a few years back. On each aiming point, there are high-contrast black horizontal and vertical lines for aligning your cross-hairs. The gray circle lets you see the bullet impacts above, without obliterating the red diamond, which is quite useful for precise aiming (we put fine cross-hairs on the points of the diamond). This target sheet includes data entry tables below each of the three aim points. There are many other free targets out there, but this format is very popular. We’re pleased to see Jim using it. You can download this and dozens of other FREE Targets from the AccurateShooter.com Target Page.
This custom war wagon hauls varmint hunters around the Longmeadow Game Resort in Colorado.
Winter is behind us — it’s officially Spring. Today, March 19, 2020, is the Vernal Equinox, the official start of Spring. For many shooters, the coming of Spring means that it’s time to head out to the varmint fields. Here are eaidht items that can help ensure successful spring varmint adventures.
Eight Great Products for Varmint Shooters
1. BarrelCool In-Action Fan
Busy Varmint shooters may expend hundreds of rounds in a day. That’s tough on barrels. One way to extend your round count is to use the ingenious BarrelCool device. This little yellow gadget fits in your action with a blower tube that goes into the chamber. A small electric fan blows cooling air through the barrel. It really works — folks who’ve purchased the Barrel Cool and run temp strips on their barrel say the BarrelCool can significantly reduce the time it takes to cool down a hot barrel.
In the past, folks have tried various methods to cool barrels: water flushed through the bore, CO2 tanks, even battery-operated fish pumps. BarrelCool is a simpler, less costly, and much handier solution. Priced at $36.99, this small device can potentially can save you money by extending barrel life. To see how Barrelcool works, visit BarrelCool.com. There you’ll find video demos of BarrelCool units in both bolt-action and AR-type rifles.
2. Uncle Bud’s Bulls Bag Sandbag
On most varmint hunts we spend most of the time shooting from a portable bench with a pedestal-type rest (we like the SEB Mini). But it’s nice having a big, heavy X-Type sandbag rig also. These four-chamber designs, such as the Uncle Bud’s Bulls Bag, allow shooting from a truck hood or any flat surface. Some rifles with narrow fore-ends really benefit from the firm “hug” provided by these “butterfly” style sandbags. We like the 15″ Uncle Bud’s Bulls Bag, currently $71.99 at Brownells. Durable and well-made, it will provide years of service. There is also a 10″ version that is easier to carry. Forum member Stoner24mkiv likes a Bulls Bag for shooting from a vehicle. He also suggests: “[take] an adjustable bipod if you are going to do any walking. Have a fanny pack or backpack for extra ammo, water, bore-snake, etc. when you go on your walkabouts. Bring a Boonie hat for blocking the sun, sun glasses, sunscreen. High leather boots.”
3. Scope with Built-In Laser Rangefinder
The Burris Eliminator III is an impressive piece of electro-optical technology. With a push of a button, a built-in laser rangefinder senses the distance to your target and the Eliminator’s microprocessor instantly calculates the required hold-over based on your load’s ballistics. The calculated aiming point is then displayed in the reticle with an illuminated red dot on the vertical cross-hair. Just put the red dot on the target and make the shot. Easy as that. If you are working a large prairie dog field and constantly moving near to far and back again, this scope is really handy. Laze, adjust aim with the dot, and squeeze the trigger. Its that simple. We’ve used this scope out to 500 yards on small steel targets and it worked flawlessly.
4. Hornady 17 HMR V-Max 500 Round Brick, $89.99
For those distant prairie dog shots, you’ll want a centerfire round such as a 22 BR/BRA or 22-250. However, for closer work, or for smaller varmints such as ground squirrels, the 17 HMR is hard to beat. There are many good factory rifles chambered for the 17 HMR, such as the Savage A17. Right now Midsouth has a Hornady 17 HMR brick of 500 for a low price of $89.99. That works out to just 18 cents per round — cheap enough that you can blast sage rats all days long and never worry about running out of ammo.
5. Stick-On Temp Strips Monitor Barrel Heat
You never want your barrel to get too hot. Accuracy suffers when barrels over-heat, and excessive heat is not good for barrel life. So how do you monitor your barrel’s temperature? You can check if the barrel is “warm to the touch” — but that method is not particularly precise. There is a better way — using temperature-sensitive strips. McMaster.com (an industrial supply house) offers stick-on temp strips with values from 86° F to 140° F. A pack of ten (10) of these strips (item 59535K13) costs $12.77 — so figure it’ll cost you about $1.28 per barrel for strips. That’s cheap insurance for your precious barrels. For best barrel life, try to stay under 120 degrees F.
6. Low-Fouling Power for High-Volume Varmint Loads
For high-shot-count varmint safaris, you want a clean-burning powder that minimizes barrel fouling. While there are many great powders for the .223 Rem, we like Hodgdon CFE 223 for our high-volume varmint loads. This powder really seems to keep barrels cleaner. Originally developed for U.S. rapid-fire military systems, CFE 223 incorporates a proprietary chemistry named “Copper Fouling Eraser”. Based on tests with extended shot strings, Hodgdon claims that, by using CFE™223, match shooters, varmint hunters, and AR shooters can maintain accuracy for longer periods, with less barrel-cleaning time.
7. Bog Pod SB-2 Sportsman’s Bipod (21″-40″)
If you’re looking for a versatile, stable and easy-to-carry field support, check out the latest BOG-POD Series SB-2 Bipod. Featuring 21″-40″ adjustable legs, the BOG-POD Bipod can be used while sitting, standing, or kneeling. This kid of support is highly recommended for shooting on hills where a conventional bipod doesn’t offer enough elevation. This unit has a 360° swivel head and the legs adjust independently out to a 60-degree angle with adjustable tension to ensure maximum accuracy. Right now you can get this SB-2 Bipod for just $19.99 on Amazon — a great deal.
8. Motorola T100 Talkabout Radios
When you’re in the varmint fields, its essential to have good communications with your fellow shooters. You can’t count on cell coverage in the hinterlands so we recommend a good pair of Walkie-Talkies. The Motorola T100s have a very impressive range (up to 16 miles in ideal conditions), yet cost just $21.99 for the pair. These 22-Channel T100 Talkabouts will run up to 18 hours on three AAA batteries. Users have been very pleased with this inexpensive handheld radios.
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. It’s a great scope for the money and at under $900 (in the USA) it’s half the price of its nearest competitor. It’s also light – at 1.5 lbs – and there are some great reticles for the F-Class shooter – like the LRMOA.
While Varget and Reloder 15 remain in short supply, you can often find IMR 4320 powder back in the shelves of local gun stores. IMR describes IMR 4320 as follows: “Short granulation, easy metering, and perfect for the 223 Remington, 22-250 Remington, 250 Savage and other medium burn rate cartridges.” This older-generation powder isconsiderably more temp sensitive than the Hodgdon Extreme propellants, but in the right application, it looks to be a viable alternative for folks who can’t source Varget, Reloder 15, and even H4895.
IMR 4320 Shoots Well in the .308 Winchester
A while back, GS Arizona wrote an excellent Riflemans Journal article, IMR 4320 — the Forgotten Powder. GS developed IMR 4320 loads for his .308 Win Palma rifle and competed with IMR 4320-powered ammo at long range matches. He concluded that: “[IMR 4320] appears to be a very useful alternative to some of the harder-to-get powders. The load is working extremely well at 1000 yards. In the [2009] Arizona Palma State Championship, several high-placing competitors were using the 4320 load. We got sub X-Ring elevation at 1000 yards from several rifles, and that’s all I’m looking for in a Palma load.”
IMR 4320 Works for Dasher Shooter
Forum member FalconPilot shoots a 6mm Dasher with Berger 105gr Hybrids. Looking for an alternative to Varget, he decided to give IMR 4320 a try. The results were good. FalconPilot reports: “I’ve been looking for other options (besides Reloder 15, which I love, but it’s really dirty). While at a gun shop in Ohio, I ran across 8 pounds of IMR 4320. I had never even heard of it, much less tried it. Getting ready for upcoming mid-range shoots, I loaded five rounds with IMR 4320 to the exact same specs as my winning Varget loads for the 6mm Dasher. This recipe was 32.7 grains of powder, Wolf SMR primer, Berger Hybrid 105 jumped fifty thousandths.” Falcon pilot tested his IMR 4320 load at 600 yards:
As you can see from the photo at the top of this article, FalconPilot had good results — a 1.5″ group at 600 yards. He reports: “This group was shoot during the middle of the day, mirage bad, scope set to 25X. It looks like IMR 4320 is a [very close] replacement for Varget… with a tad bit slower burn rate.” FalconPilot tell us the accuracy with IMR 4320 rivals the best he has gotten with Varget: “This gun has always shot under 2 inches [for 5 shots] at 600 yards, and most of time shoots 1.5 to 1.7 inches.”
For comparison purposes, here are Heat of Explosion and Burn Rate values from QuickLOAD for IMR 4320, and for the popular Reloder 15 and Varget powders. You can see that these powders have similar characteristics “by the numbers”:
Manufacturer
Powder Brand
Heat of Explosion
Burning Rate Factor
IMR
4320
3890
0.5920
Alliant
Reloder 15
3990
0.5200
Hodgdon (ADI)
Varget
4050
0.6150
WARNING — When changing from one powder to another, always start with manufacturer’s stated load data. Start low and work up incrementally. Never assume that loads will be equivalent from one powder to another, even powders with similar burn rates.
What Other Forum Members Say:
I was using IMR 4320 in the mid 70s in my .222 Rem. Darned great powder and I never had a load that was not accurate from the .222 to .30-06 with that powder. — 5Spd
A fine powder overshadowed by the nouveau wave of “gotta have the newest — make me a better shot” powders. Try 4320 in a 22-250 — what a well-kept secret! IMR 4320 meters very well and is a flexible alternative to many of the hard-to-find powders so much in demand. — AreaOne
IMR 4320 was my “go to” powder in my .223 for many many years. This powder and Winchester 55gr soft point bulk bullets (the cheapest bullet I could buy at the time) accounted for thousands of prairie dogs, coyotes, and anything else that needed shooting. I still use IMR 4320 in some .223 loads and am very happy with it still. — pdog2062
I’ve been using it in a .308 Win for several years. I think it is very sensitive to temperature and always waited till the last minute to load my ammo with a close eye on the weekend forecast at the range. IMR 4320 Works pretty good for 155gr Palma and 168gr Hybrid [bullets] in my .308. — JayC
IMR 8208 XBR is also good — if you can find it
Another good substitute for Varget powder in a .223 Rem or .308 Winchester is IMR 8208 XBR. In our own .308 Win tests, this generated slightly more velocity than Varget, with good ES/SD. However, this very good IMR 8208 XBR powder is out-of-stock at many vendors.
Do I Need to Break-In a New Rifle Barrel?
While Varget and Reloder 15 remain in short supply, you can often find IMR 4320 powder back in the shelves of local gun stores. IMR describes IMR 4320 as follows: “Short granulation, easy metering, and perfect for the 223 Remington, 22-250 Remington, 250 Savage and other medium burn rate cartridges.” This older-generation powder is considerably more temp sensitive than the Hodgdon Extreme propellants, but in the right application, it looks to be a viable alternative for folks who can’t source Varget, Reloder 15, and even H4895.
