This video shows the process of cut-rifled barrel-making by Krieger Barrels, one of the world’s best barrel manufacturers. Krieger cut-rifled barrels have set numerous world records and are favored by many top shooters. The video show the huge, complex machines used — bore-drilling equipment and hydraulic riflers. You can also see how barrels are contoured, polished, and inspected.
For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.

“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. 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.” — Geoffrey Kolbe, Border Barrels.
The 2023 F-Class National Championships commences October 29th at the Ben Avery Range outside Phoenix, Arizona. With economic inflation and the high price of gas in particular we know some F-Class shooters couldn’t make it to Nationals this year. For them, and other folks who are getting started in the sport, here are some special targets that let you train at your home range, even if it does not have target bays at 600 and 1000 yards. These special 300-yard target centers let you duplicate the exact MOA size of the official F-Class targets, but at closer range.
Here is the sleek, carbon-stocked .308 Win rifle Bryan Litz used to win both the 2015 Mid-Range AND Long-Range F-TR Championship at the Ben Avery Range in Phoenix, Arizona.
These reduced-size target centers were created by Forum member SleepyGator, an F-Class competitor who needed practice targets he could use at 300 yards. There is an official reduced-distanced standard for 300-yard F-Class matches. This utilizes the NRA No. MR-63FC – F-Class Target Center which is pasted over the MR-63 target. It provides a 1.42″ X-Ring, 2.85″ 10-Ring, and 5.85″ Nine-Ring. (The dimensions of F-Class targets are found in the NRA High Power Rules, Sec. 22, part 4, page 70-71 — see sample below.)
To duplicate the 300-yard target, SleepyGator has prepared a printable version of the MR-63FC Target Center, along with a pair of training targets with two bulls and five bulls. The two-bull and five-bull targets mirror the scoring rings on the MR-63FC, but they display only the innermost three rings and two rings respectively. All three targets are Adobe Acrobat (PDF) files that can be easily printed. You may need to adjust the scale (sizing) on your printer to get the dimensions exactly correct. As noted above, when printed, the 10-Ring on all three targets should measure 2.85″. This should provide some handy practice targets you can use between matches. Thanks to SleepyGator for providing these targets. You can download all three as a .Zip archive. After downloading the .Zip file, just click on the .Zip archive to extract the individual targets.
Barrel-maker Dan Lilja’s website, RifleBarrels.com has an excellent FAQ page that contains a wealth of useful information. On the Lilja FAQ Page you’ll find answers to many commonly-asked questions. For example, Dan’s FAQ addresses the question of barrel life. Dan looks at factors that affect barrel longevity, and provides some predictions for barrel life, based on caliber, chambering, and intended use.
NOTE: This article was very well-received when it was first published. We are reprising it for the benefit of readers who missed it the first time.
Dan cautions that “Predicting barrel life is a complicated, highly variable subject — there is not a simple answer. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.” Dan also notes that barrels can wear prematurely from heat: “Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups.”
Q. What Barrel Life, in number of rounds fired, can I expect from my new barrel?
A: That is a good question, asked often by our customers. But again there is not a simple answer. In my opinion there are two distinct types of barrel life. Accurate barrel life is probably the type most of us are referencing when we ask the question. But there is also absolute barrel life too. That is the point where a barrel will no longer stabilize a bullet and accuracy is wild. The benchrest shooter and to a lesser extent other target shooters are looking at accurate barrel life only when asking this question. To a benchrest shooter firing in matches where group size is the only measure of precision, accuracy is everything. But to a score shooter firing at a target, or bull, that is larger than the potential group size of the rifle, it is less important. And to the varmint hunter shooting prairie dog-size animals, the difference between a .25 MOA rifle or one that has dropped in accuracy to .5 MOA may not be noticeable in the field.
The big enemy to barrel life is heat. A barrel looses most of its accuracy due to erosion of the throat area of the barrel. Although wear on the crown from cleaning can cause problems too. The throat erosion is accelerated by heat. Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups. A cartridge burning less powder will last longer or increasing the bore size for a given powder volume helps too. For example a .243 Winchester and a .308 Winchester both are based on the same case but the .308 will last longer because it has a larger bore.
And stainless steel barrels will last longer than chrome-moly barrels. This is due to the ability of stainless steel to resist heat erosion better than the chrome-moly steel.
Barrel Life Guidelines by Caliber and Cartridge Type
As a very rough rule of thumb I would say that with cartridges of .222 Remington size you could expect an accurate barrel life of 3000-4000 rounds. And varmint-type accuracy should be quite a bit longer than this.
For medium-size cartridges, such as the .308 Winchester, 7×57 and even the 25-06, 2000-3000 rounds of accurate life is reasonable.
Hot .224 caliber-type cartridges will not do as well, and 1000-2500 rounds is to be expected.
Bigger magnum hunting-type rounds will shoot from 1500-3000 accurate rounds. But the bigger 30-378 Weatherby types won’t do as well, being closer to the 1500-round figure.
These numbers are based on the use of stainless steel barrels. For chrome-moly barrels I would reduce these by roughly 20%.
The .17 and .50 calibers are rules unto themselves and I’m pressed to predict a figure.
The best life can be expected from the 22 long rifle (.22 LR) barrels with 5000-10,000 accurate rounds to be expected. We have in our shop one our drop-in Anschutz barrels that has 200,000 rounds through it and the shooter, a competitive small-bore shooter reported that it had just quit shooting.
Remember that predicting barrel life is a complicated, highly variable subject. You are the best judge of this with your particular barrel. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.
Benchrest Barrel Life — You May Be Surprised
I thought it might be interesting to point out a few exceptional Aggregates that I’ve fired with 6PPC benchrest rifles with barrels that had thousands of rounds through them. I know benchrest shooters that would never fire barrels with over 1500 shots fired in them in registered benchrest matches.
I fired my smallest 100-yard 5-shot Aggregate ever in 1992 at a registered benchrest match in Lewiston, Idaho. It was a .1558″ aggregate fired in the Heavy Varmint class. And that barrel had about 2100 rounds through it at the time.
Another good aggregate was fired at the 1997 NBRSA Nationals in Phoenix, Arizona during the 200-yard Light Varmint event. I placed second at this yardage with a 6PPC barrel that had over 2700 rounds through it at the time. I retired this barrel after that match because it had started to copper-foul quite a bit. But accuracy was still good.
CCI and Federal Premium are both brands of Vista Outdoor. Most CCI rimfire is produced in Idaho, while other Federal-branded rimfire ammo is produced in Federal’s Anoka, Minnesota facilities. Here we feature videos from both CCI and Federal ammo plants. Watch and learn how rimfire ammo is made.
Field & Stream Tours Federal Ammo Plant in Minnesota
A reporter for Field & Stream recently got a chance to tour the Federal ammunition production facility in Anoka, Minnesota. This large plant produces both rimfire and centerfire ammunition. While touring the plant, the reporter was allowed to capture video showing the creation of .22 LR rounds from start to finish. This is a fascinating video, well worth watching.

.22 LR Ammo Production at CCI Ammo Plant in Idaho
Back in 2016, YouTuber 22Plinkster was able to tour the CCI Ammo plant in Lewiston, Idado. Here is the rimfire production video he produced.
The Manufacturing Process for .22 LR Rimfire Ammunition Shooting Sports USA explains: “Rimfire cartridge cases are the oldest self-contained cartridge in existence, having been in continuous production since the mid-1850s. Rimfire cases are drawn from a thin piece of brass and formed with a hollow rim. A priming compound is then forced into the case using centrifugal force, where it is charged with powder and a bullet is seated in the mouth of the case. The case is then crimped around the bullet to ensure sufficient push and pull when the round is fired. When the firing pin strikes the thin brass rim of the case, the hollow rim is crushed and the primer is ignited.” Source: SSUSA.org 9/2/2017.
Will you be traveling (with firearms) to other states this fall? Are you concerned about the laws that might apply when you are transporting guns across state lines? Or are you puzzled about the requirements for obtaining a carry permit in your own state? If you have any of these questions, you should definitely get expert guidance on State statutes and regulations controlling firearms. To do that, you can purchase Attorney Scott Kappas’s Traveler’s Guide to the Firearms Laws of the 50 States for just $10.00 on Amazon (or $19.95 from publisher). The latest 2023 edition includes 100+ updates since last year. In addition, there are multiple new and expanded sections for 2024.
If you don’t want to spend the money on the book, there is a FREE alternative. There’s a very helpful set of State Law Summaries on the web, presented by PewPewTactical.com. Despite the silly name, the PewPewTactical website has an abundance of information that is particularly beneficial for pistol shooters and CCW holders.
One of the best features of PewPewTactical.com is the Gun Laws by State online reference guide. We looked through four of these State Law Summaries and were impressed by the depth of the coverage. But we caution — if you have specific legal questions, particularly with recently-enacted statutes, you should consult a licensed attorney for your state (or the state to which you will travel). In addition, many of the State Law Summaries have not been updated for 3-5 YEARS! But they are still a good place to start. Below are links to state law articles from PewPewTactical.com.

How and Why to Create a Dummy Round
When you have a new custom rifle built, or a new barrel fitted to an existing rifle, it makes sense to create a dummy round. This should have your preferred brass and bullet types, with the bullet positioned at optimal seating depth. A proper dummy round helps the gunsmith set the freebore correctly for your cartridge, and also ensure the proper chamber dimensions.
Respected machinist, tool-maker, and gunsmith Greg Tannel of Gre-Tan Rifles explains: “I use the dummy round as a gauge to finish cut the neck diameter and throat length and diameter so you have [optimal] clearance on the loaded neck and the ogive of the bullet just touches the rifling.” He recommends setting bullet so the full diameter is just forward of the case’s neck-shoulder junction. “From there”, Greg says, “I can build you the chamber you want… with all the proper clearances”.
Greg Tannel has created a very helpful video showing how to create a dummy round. Greg explains how to measure and assemble the dummy and how it will be used during the barrel chambering process. Greg notes — the dummy round should have NO Primer and No powder. We strongly recommend that every rifle shooter watch this video. Even if you won’t need a new barrel any time soon, you can learn important things about freebore, leade, and chamber geometry.
Must Watch Video — This has been viewed over 790,000 times on YouTube:
This has been a very popular video, with 782,000 views! Here are actual YouTube comments:
That is the best explanation I’ve ever seen. Thank you sir. — P. Pablo
Nice video. You do a very good job of making this easy for new reloaders to understand. I sure wish things like this were available when I started reloading and having custom rifles built. Once again, great job, and your work speaks for itself. — Brandon K.
Beautiful job explaining chambering clearances. — D. Giorgi
Another Cool Tool — The Stub Gauge
When you have your gunsmith chamber your barrel, you can also have him create a Stub Gauge, i.e. a cast-off barrel section chambered like your actual barrel. The stub gauge lets you measure the original length to lands and freebore when your barrel was new. This gives you a baseline to accurately assess how far your throat erodes with use. Of course, as the throat wears, to get true length-to-lands dimension, you need take your measurement using your actual barrel. The barrel stub gauge helps you set the initial bullet seating depth. Seating depth is then adjusted accordingly, based on observed throat erosion, or your preferred seating depth.
We first ran this article in 2012, and it was very well received. Since then, many Forum members have requested an explanation of MILS and mildots, so we decided to run this feature again…
1 Milliradian (Milrad or ‘Mil’) = 1/1000th of a radian | 1 Milliradian = 0.0573 degrees.
In this NSSF Video, Ryan Cleckner, a former Sniper Instructor for the 1st Ranger Battalion, defines the term “MilliRadian” (Milrad) and explains how you can use a mildot-type scope to range the distance to your target. It’s pretty simple, once you understand the angular subtension for the reticle stadia dots/lines. Cleckner also explains how you can use the milrad-based reticle markings in your scope for elevation hold-overs and windage hold-offs.
Even if you normally shoot at known distances, the hold-off capability of milrad-reticle scopes can help you shoot more accurately in rapidly-changing wind conditions. And, when you must engage multiple targets quickly, you can use the reticle’s mil markings to move quickly from one target distance to another without having to spin your elevation turrets up and down.
WEB RESOURCES: If you want to learn more about using Milliradians and Mildot scopes, we suggest the excellent Mil-dot Explained article from targettamers.com Guide. This covers the basics you need to know, with clear illustrations.
Also informative is The Truth about Mil Dots by Michael Haugen. Mr. Haugen begins with basic definitions: 360 degrees = 2 x Pi (symbol π) Radians. That means 1 Radian is about 57.3 degrees. 1 Milliradian (Milrad or ‘Mil’) = 1/1000th of a radian. Thus 1 Milliradian = .0573 degrees.
AR-platform rifles can be maintenance-intensive beasts. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too much oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt and bolt carrier will be less of a burden.
Here is a good video that explains AR-15 Cleaning and Maintenance. In this 30-minute NSSF video, Gunsite Academy instructor and gunsmith Cory Trapp discusses the proper way to clean and maintain the AR-15 carbine. Very knowledgeable, Trapp provides rock-solid advice for AR owners. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here’s another good video that explains how to properly disassemble and clean AR-platform rifles.
Take-Down and Full Cleaning of AR15 by Jerry Miculek
Here ace shooter Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.
A good riflescope is essential for many types of competition, and the vast majority of hunters have scoped rifles. Some F-Class and benchrest competitors are now using optics with up to 60X magnification. Over the past 30 years, scopes have continued to evolve with improved glass, more reticle types, vastly increased elevation travel, bigger main tubes, FFP and SFP options, and even built-in electronics.
When shopping for a riflescope, it’s useful to understand how scopes work — how the internal mechanisms control windage and elevation, how parallax controls work, and how magnification levels are controlled.
Basics of How Riflescopes Work
This Burris video (above) covers the key aspects of scope function: zoom magnification, windage control, elevation control, parallax control (front or side mount), and ocular lens focus. There are some tips on getting a new scope running smoothly — it’s wise to rotate the power control a few times as well as both windage and elevation knobs. The video below also explains how to set ocular focus controls optimally.
Scope Break-In Methods and Diagnosing Issues — Great Video
We recommend that all serious shooters watch this video start to finish. A very knowledgeable scope engineer, Leupold’s Mike Baccellieri, explains the fine details of scope operation — with very useful recommendations on how to ready a new scope for use (See 36:50 time-mark). With a new optic he advises to run the controls multiple times to full travel. Also, take your time to get the diopter control just right (See 26:40 time-mark).
The video also explains why, with a new scope or one that hasn’t been used much, it is sometimes effective to rotate the elevation PAST the desired setting then come back a click (See 35:40 time-mark). In addition, near the end of the video, the expert explains how you can use a mirror to determine if the scope mount (base and/or rings) is NOT aligned with the bore axis, forcing excess travel to get on target (See 42:00 time-mark). We have seen this caused by scope rails attached slightly off axis.
Large diameter turrets make windage and elevation markings easier to see, and the click “feel” may be more noticeable given the greater diametrical travel between clicks.
First Focal Plane (FFP) vs. Second Focal Plane (SFP)
The main visual difference between First Focal Plane (FFP) and Second Focal Plane (SFP) scopes is the appearance of the reticle (and its hash marks) at different magnification levels. With a FFP scope, the reticle increases in visible size (and line thickness) with increased magnification. This is so the angular hash marks remain constant (in Mils or MOA angular span) at all magnification levels. So, on a 10-30X FFP scope, a 0.1 Mil hash mark represents the SAME angular measurement at 10X, 20X, or 30X (or any magnification). The downside of the FFP system is that the reticle lines can appear very thick at high magnification. But for a PRS/NRL match, with targets at multiple distances, it is important that the hash marks represent the same angular measurement at all power settings.
On a Second Focal Plane (SFP) scope, by contrast, the reticle lines (and hash marks) appear visually (in thickness) the same at all magnification levels. This means the hash mark divisions will only be precise at one magnification level, as designed by the manufacturer. For example, you could have exact 1 MOA Hash marks at 10X. But zoom the scope to 20X and the same reticle hash mark would then cover 2 MOA. SFP scopes are popular with competition shooters who shoot at specific known distances. Not having thick reticle lines at 25X to 50X is an advantage when aiming at precise benchrest and F-Class targets.
ZEISS now makes excellent FFP Scopes with both MOA and Milrad options
Minute of Angle (MOA) vs. Milliradian (MILRAD or MIL)
This video also explains MOA vs. MRAD (Milliradian) controls. A Minute of Angle (MOA) is an angular measurement that represents 1.047″ at 100 yards. Modern MOA scopes are typically configured with 1/4 MOA or 1/8 MOA clicks. A Milliradian (MRAD) is another angular measurement defined as one-thousandth of a radian. Milrad scopes are commonly configured with 0.1 Milrad clicks. How much is a 0.1 mil at 100 yards? One mil equals 3.6 inches at 100 yards; therefore, 1/10th of that, 0.1 Mil, equals 0.36” – roughly a third of an inch – at 100 yards. That’s pretty close to the common quarter-inch (1/4 MOA) increment found on MOA riflescopes.
Sightron makes excellent high-magnification SFP zoom scopes favored by many competitors. These have proven quite reliable and offer very good performance for the price.
Scope Mounting Method and Alignment
When mounting a scope, you want to make sure the scope is aligned properly, so that vertical travel is precisely up and down, not offset. Begin by supporting the rifle with a good front and rear rest. Use a portable level to ensure the rifle is not tilting slightly left or right around the barrel bore axis. Then you want to align your scope’s vertical axis. For this, we recommend setting up a plumb bob — a weighted line that hangs straight down. This can be set up indoors or outdoors. Align your reticle’s vertical axis precisely with the plumb bob line, making sure not to move the rifle.
One caution — we have seen some riflescopes that are internally off-axis by up to 4 degrees. In this case, you can align the reticle’s vertical axis with the plumb bob line but then find that your turrets are slightly titled. That is a scope manufacturing fault that will result in some error when you input a large click value (e.g. 10+ MOA up or down).
When mounting your scope, another key factor to consider is the eye relief — the distance of the rear “ocular” lens to your eye. When mounting the scope, put your head in the position at which you normally shoot. NOTE: As your optimal head position may be quite a bit different when shooting prone vs. shooting from a bench, you may want to adjust the scope placement for different shooting positions. This Editor had to move his comp rifle scope about an inch rearward when local club matches changed from prone to bench.
Sherri Jo Gallagher, the second woman in history to win the NRA High Power National Championship, sports Eye Protection at Camp Perry. The first lady High Power Champion was Sherri’s mother, Nancy Tompkins.
In response to a Bulletin article about Protective Eyewear, one of our Canadian readers posted a personal story. His account demonstrates the importance of wearing eye protection whenever you shoot — no matter what type of firearm you are using — even air rifles. We hope all our readers take this to heart. All too often at rifle matches we see shooters, even some top competitors, risking their vision by failing to wear eye protection.
Eye and Hearing Protection are now MANDATORY for Highpower Rifle competitors and Pistol shooters in all CMP-affiliated matches. The 2020 CMP Highpower Rifle, Pistol, and CMP Games Rulebooks all contain the following rule: “All competitors and competition officials are required to wear appropriate eye and hearing protection when on shooting range firing lines during highpower rifle or pistol firing. All competitors must comply with this requirement before they can participate in a CMP sponsored or sanctioned competition. Competitors are responsible for selecting their eyewear and hearing protection.”
Eye Protection — Lesson Learned by Nicholas from Canada
As a boy on a mixed farm on the plains the first shooting stick I owned was a Red Ryder BB gun. My Dad bought it for me as I showed a keen interest in the shooting and hunting sports. I was about 9 years old at the time.
We had literally thousands of sparrows in our large farm yard and they liked to roost on the steel railings in the barn loft. I took to slowly thinning out their ranks by flashlight at night as these little winged pests settled in the farm buildings.
One evening as I slayed sparrow after sparrow in the barn loft — with about a dozen farm cats following me to consume these easy meals, I fired at another bird centered in my flashlight beam.
However, my aim was a bit low — and the copper pellet hit the steel beam square on. Instantly I felt a sharp pain as the BB bounced back and hit me squarely between the eyes on the bridge of my nose – drawing blood from the partial penetration into the skin. A half inch either way and I’d have lost an eye!
Never, never, never shoot at any target with a steel background with any firearm, even a BB gun – is the hard lesson I learned, and wear the best shooting glasses that money can buy!
PLEASE REMEMBER THAT!!
Editor’s Comment: Among competitive pistol shooters, the use of safety eyewear is universal. You’ll never see Rob Leatham, Julie Golob, or Jerry Miculek competing without eye protection — for good reason. The handgun sports’ governing bodies effectively enforce mandatory eye protection policies. We wish the same could be said for competitive rifle shooting. We often see benchrest, High Power, and F-Class competitors shooting without eye protection. We’ve heard all the excuses, yet none of them trump the safety considerations involved.
We recommend that all shooters and hunters employ eye protection whenever they use firearms or are at a location where live fire is taking place. You only have two eyes. A tiny bullet fragment or ricochet is all it takes to cause permanent blindness in one or both eyes. As rifle shooters, we place our eyes a couple inches away from a combustion chamber operating at pressures up to 70,000 psi. I know quite a few guys who will religiously put on safety glasses when running a lathe or a drill press, yet the same guys won’t use eye protection when shooting their rifles — simply because it is “inconvenient”. That’s nuts. It doesn’t matter is you are a cub scout or a multi-time National Champion — you should wear eye protection.
I will give you a personal example. A year ago I was shooting a 9mm pistol. One of the cartridges had a primer burst outward blowing small particles, some brass, and a piece of the pistol’s extractor right back into my eyes. Thankfully I was wearing good wrap-around safety glasses. No injuries at all. But without those safety glasses, this could have been very serious. I always wear safety glasses with ALL firearms. Shown below is the same kind of primer blow-out I experienced, but with a .270 Win rifle cartridge.
Be wise — protect your eyes. To learn more about eyewear safety standards, and to learn about the latest options in ANSI Z87-certified protective eyewear, read our article on Eye Protection for Shooters.
In this NSSF Video, Ryan Cleckner, a former Sniper Instructor for the 1st Ranger Battalion, defines the term “MilliRadian” (Milrad) and explains how you can use a mildot-type scope to range the distance to your target.
