Need something for the walls of your “man cave” or reloading room? Looking for a great birthday gift for one of your shooting buddies? The creators of the Cartridge Comparison Guide offer a collection of wall posters showing ammunition types from 17 caliber rimfire cartridges all the way up to giant 35mm military rounds. ChamberIt.com currently offers 15 different large wall posters that display a huge variety of cartridge types. For example, the American Standard Poster (shown above) contains every standardized cartridge mass produced in the USA as of 2021. The cartridges are 100% to scale (life size). These posters feature full color images on high gloss / high quality 100-lb poster paper.
For example, the new MSR & AR Cartridges poster contains 60 cartridges that are commonly available in either a standard, customized, or proprietary MSR or AR platform with calibers from .17 Cal up to .500 Cal. This $14.92 poster displays 60 rifle cartridge types at true size (within 4/1000 of an inch).

At AccurateShooter.com, our primary focus is precision target shooting with rifles. But it’s definitely fun to shoot pistols too, and we bet most of our regular readers own handguns. Here are five tips for shooting safely and accurately with handguns. These pointers will help you advance your skills and have more fun with your pistols and revolvers.
1. Make Sure Safety Is Number One
Whether you own one gun or one hundred, gun safety must always be your main priority. In this video, Smith & Wesson Team Captain Julie Golob covers the basics of gun safety.
2. Start with a .22 LR Handgun
We strongly recommend that new pistol shooters start off with a .22 LR rimfire handgun. The .22 LR cartridge is accurate but has very low recoil, less “bark” than a centerfire, and very little smoke and muzzle flash. New shooters won’t have to fight muzzle flip, and won’t develop a flinch from the sharp recoil and muzzle blast common to larger calibers. With the .22 LR, the trainee can focus on sight alignment, breathing, and trigger pull. When he or she has mastered those skills, move on to a .38 Special or 9mm Luger (9x19mm).
What gun to use? We recommend the 10-shot Smith & Wesson Model 617. This is ideal for initial training, shooting single action, slow-fire. You want to focus on sight picture and holding steady. Shown above is the 4″-barrel Model 617 which balances well. There is also a 6″-barrel version. It has a longer sight radius, but is a little nose-heavy. Both are great choices. They are extremely accurate and they boast a very clean, precise trigger.
If you prefer a semi-auto .22 LR pistol, we recommend the Browning Buck Mark series. Buck Marks are very accurate and very reliable. There are now 58 different Buck Mark models, priced at $469.99 to $839.99 MSRP. Retail prices start at about $330 for a basic Buck Mark Camper 22 UFX model. Like the S&W Model 617, a good Buck Mark will serve you for a lifetime.
3. Use Quality Targets with Multiple Aim Points
It’s common for new pistoleros to start shooting at cans or clay birds at a public range. That can be fun, but it’s better to start with proper targets, placed at eye level, at 7-10 yards. We like to use targets with large, brightly colored circles. Focus on putting 5 shots in a circle.
We recommend targets that have multiple bullseyes or aiming points — that way you don’t have to constantly change your target. There are also special paper targets that can help you diagnose common shooting problems, such as anticipating recoil. EZ2C makes very good targets with bright, red-orange aim points. You can also use the bright orange Birchwood Casey stick-on Target Dots (right). These come in a variety of diameters. We like the 2″ dot at 10 yards.
Too many new pistol shooters try to move right to rapid fire drills. It’s better to start slow, practicing the basics, under the guidance of a good mentor. If you belong to a club, ask if there are certified instructors who will help out. This Editor learned pistol shooting from a seasoned bullseye shooter, who got me started with a .22 LR revolver and very close targets. Over the course of a few range sessions we progressed to farther targets and faster pace. But the fundamentals were never forgotten. When starting your pistol training, it’s wise to view some instructional videos. Top Shot Champion Chris Cheng hosts an excellent Handgun 101 Series produced by the NSSF. We’ve linked one of these Handgun 101 videos for Tip #6.
5. SLOW DOWN — This Is Not a Race
When you learned to ride a bicycle, you started slow — maybe even with training wheels. The same principle applies to pistol shooting. When you get started with handguns, we recommend you shoot slowly and deliberately. Start with the handgun unloaded — just work on your sight alignment and breathing. With snap caps in place, try some dry-firing drills. Then progress to live fire. But be deliberate and slow. With the target at 20 feet, see if you can get three successive shot-holes to touch. Believe it or not, many common pistols are capable of this kind of accuracy (but you won’t see many shooters at indoor ranges who pursue that kind of precision). Once you master your form and accuracy, then you can work on your speed.

Q: What is the most popular gun book in the history of the planet?
A: That distinction goes to the Shooter’s Bible, which has sold over 7 MILLION copies since it was first published over 80 years ago.
Released in October 2025, the 117th Edition of this respected resource is better than ever. This latest Shooter’s Bible boasts 608 pages with over 270 color photos and more than 1000 black-and-white photos. The latest 117th Edition features many new firearms as well as new optics. This paperback book is now just $25.35 on Amazon, 15% off the $29.99 list price. A Kindle digital edition is also available for $21.99 on Amazon.
Published annually for more than eighty years, the Shooter’s Bible is one of the most comprehensive firearms reference guides in print. The publishers claim that “nearly every firearms manufacturer in the world” is included. The 117th Edition also contains new and/or enhanced sections on ammunition, optics, and accessories, along with updated handgun and rifle ballistic tables. There are also extensive charts of currently available hunting and match bullets for hand-loaders.
While many shooters are now using the internet to get reloading data and equipment specifications, the Shooter’s Bible remains a valuable resource with a great legacy. As one recent Shooter’s Bible purchaser explains: “While it’s true that much of the information contained in the Shooter’s Bible can be found on the Internet, there are many of us who would first rather relax in our easy chair and page through the book at our leisure. If you find an item that catches your fancy, you can then follow up by going to their Web site.”
Another buyer observed: “This [117th edition] is proof that, even with all the attacks on our 2nd Amendment right over the years, the industry has persevered and grown. I hope the day never comes when there will no longer be a reason to publish the Shooter’s Bible.”
The Shooter’s Bible contains a vast collection of firearms product information and descriptions. Hundreds of firearms are listed, complete with specifications and photos. Products from nearly all commercial gun makers on the planet are included.

“The press is the heart of the handloading operation, also traditionally the most expensive single tool employed…” — Laurie Holland
British competitive shooter Laurie Holland has reviewed three popular, single-stage reloading presses for Target Shooter Magazine (targetshooter.co.uk). Laurie bolted up a Forster Co-Ax, RCBS Rock Chucker Supreme, and RCBS Summit to his reloading bench and put the three presses through their paces. These three machines are very different in design and operation. The venerable Rock Chucker is a classic heavy, cast-iron “O”- type press that offers lots of leverage for tough jobs. The smaller RCBS Summit press is an innovative “upside-down” design with a large center column and open front. It offers a small footprint and easy case access from the front. The Co-Ax is unique in many respects — dies slide in and out of the upper section which allows them to “float”. The cartridge case is held in the lower section by spring-loaded jaws rather than a conventional shell-holder.
If you are considering purchasing any one of these three presses, you should read Laurie’s article start to finish. He reviews the pros and cons of each press, after processing three different brands of brass on each machine. He discusses ergonomics, easy of use, press leverage, smoothness, priming function, and (most importantly), the ability to produce straight ammo with low run-out. The review includes interesting data on case-neck run-out (TIR) for RWS, Federal, and Norma 7x57mm brass.
Review Quick Highlights:
RCBS Rock Chucker Supreme
“My expectations of the antediluvian RCBS Rock Chucker Supreme’s performance weren’t over high to be honest as I mounted it in the place of the Summit. As soon as I sized the first of the stretched RWS cases though, I saw why this press has been such a long-running favorite. The workload was considerably reduced compared to the other two presses and doing 40-odd cases took no time at all with little sweat — it just eats hard-to-size brass.”
RCBS Summit Press
“Despite its massive build and long-stroke operating handle, [the Summit] took more sweat than I’d expected, even if it was somewhat less work than with the Co-Ax. Although the Summit is apparently massive, I noticed that the die platform would tilt fractionally under the heaviest strains[.] It is nevertheless a very pleasant press in use and bullet seating was a doddle — the few examples tried proving very concentric on checking them afterwards. The optional short handle would be valuable for this task.”
Forster Co-Ax
“[On the Co-Ax], the operating handle is above the machine, located centrally here [with] twin steel links at the top end of the press dropping down to the moving parts. The Co-Ax incorporates a number of novel features, principally its automatic and multi-case compatible shell-holder assembly with spring-loaded sliding jaws, very neat spent primer arrangements that allow hardly any gritty residues to escape and foul the moving parts and, the snap-in/out die fitment that allows rapid changes and also sees the die ‘float’ in relation to the case giving very concentric results. I own this press and it meets my handloading needs very well.”
The 2026 Southwest Nationals (SWN) competition concludes this afternoon, February 15, 2026, at the Ben Avery range in Arizona. With skilled shooters in Sling, F-TR, and F-Open classes, the SWN is one of the USA’s most popular multi-class, long-range rifle events held annually. We’ll have a full report on SWN individual and team final results tomorrow.
To show the type of rifle that can win a SWN title, today we feature the .308 Winchester F-TR rifle of talented F-Class shooter Peter Johns. With this impressive rig, Peter won the F-TR Division at the 2020 Berger SW Nationals (SWN), after finishing second in 2019. And Peter also won mid-range AND long-range Texas State championships in 2019. Along the way Peter set a new 600-yard NRA National F-TR Record (200-18X), and tied the 600-yard F-TR Aggregate Record with 600-47X. This Sunday GunDay story features Peter and his trophy-grabbing .308 Win F-TR rifle.
How to Campaign a Winning .308 Winchester F-TR Rifle
Report by Peter Johns
I started contemplating F-Class shooting after talking with Darrell Buell at SHOT Show a decade ago. My first F-Class match was with a Savage VLP with a 26″ Shilen 7mm SAUM barrel and a Harris bipod. After that initial match in Texas I knew I had a lot to learn. I decided that F-TR was the place to start. This story follows my development as an F-TR shooter and showcases the rifle that delivered multiple F-TR match wins in 2019 and 2020.

Equipment Showcase — Key Components of Peter’s F-TR Rifle
Omar Alonzo (Alonzo Custom Rifles, (713) 283-4384, Gunbuilder284@gmail.com) does all my gunsmithing. I believe this is one of the major reasons I have been doing so well in the last couple years. He does a phenomenal job with rifle bedding. He also fixed the timing on my action. The first barrel he chambered has really helped me win matches and set records.
In this Video, Peter talks about his key rifle components and gear:
McMillan Kestros BR Stock — I switched to a Kestros BR stock when they first came out. I painted the stock myself. I am very grateful to Kelly McMillan for letting me be one of the first to try them. The Kestros BR tracks better than any stock I have tried. NOTE — the Kestros was so light that I had to add a steel bar under the forearm to get closer to the F-TR weight limit with a 30″ HV barrel. [Editor: That has the advantage of lowering the center of gravity and the bar can slide fore/aft to adjust center of balance]. I use a SEB Bigfoot rear bag with slick ears and 3/4″ spacing. When I got the Kestros I thought the rear bag spacing was too wide but it worked so well I didn’t change.
Kelbly (Stolle) Panda Action and Krieger Barrel — My rig has a Kelbly Panda F-class action with a Bix’N Andy trigger. At the Berger SWN, I used a Krieger 1:10″-twist 30″ HV 4-groove barrel. It is superbly accurate. I have been bouncing between Krieger and Bartlein for barrels for the last few years. The best barrel I have had is a 30″ Krieger 4-groove HV, however the Bartleins have been very good as well.
Duplin Bipod with Articulating Feet — I really liked the Pohlabel articulating feet that are available for the SEB JoyPod so I asked Dan Pohlabel for permission to copy his feet. I bought some aluminum and made the best copy I could. Since SWN, Duplin has coming out with a new bipod with articulating feet which are considerably better than the feet I made. I use a board and a piece of stall mat with carpet glued on it for the bipod to sit on.
Vortex Golden Eagle Scope — I use the 15-60x52mm Vortex Golden Eagle on all my F-Class rifles. I see the mirage better with the Golden Eagle than any other scope and it tracks perfectly. I also use a Vortex Razor spotting scope with long eye relief lens on the line to help watch mirage and flags. I also use the Razor spotting scope to call wind for Team Texas.
Cleaning Procedure — Less is More — No Cleaning During SWN Long Range Event
Peter has learned that he can go for long round counts without cleaning: “I have found that my .308 Win rigs, for the most part, shoot really well dirty. I can usually get 300 or more rounds before cleaning. I cleaned my barrel at the 2020 SWN after the mid-range event and fouled it before the long-range. I did not clean my barrel again until I got home from the match.”
Peter does clean thoroughly when he gets home: “After a big match I clean my rifles with Boretech Eliminator and a bronze brush followed by Iosso until the majority of carbon is removed from the barrel, as verified with a Lyman borescope. After a thorough cleaning, I find that I need to shoot a bunch of foulers. I will usually go to my practice range and shoot a 20-shot practice match and I will see the accuracy tighten up in the back half.”

Peter’s Match Load and Reloading Methodology
Loading for .308 Win F-TR — Do What Matters
My loading technique has evolved almost full circle from where I started. I went from the basics to doing every step a person could conceive. Then I decided to start testing all the different steps to see what didn’t matter or made things worse. I am now back to almost no steps in my reloading process. I don’t clean brass anymore. I just wipe the case off, lube, size, prime, and load. I anneal when I feel the necks getting inconsistent when seating the bullets. I pre-load all my ammo for matches. I tried seating them at the match but I didn’t find it to matter on the score card and it takes my focus away from conditions.
Peter’s 2020 SWN-winning .308 Win load consists of Berger 200.20X bullets, Lapua Palma brass, Federal 205M primers, and Varget powder. Peter revealed: “The Berger 200-grainers are running in the mid-2600 fps range. I have tried them much faster but found the best consistency at this speed.”
Peter measures powder to the kernel and also weighs/sorts other components. He runs Berger 200.20X bullets slightly off the lands in a 0.170 freebore chamber. Notably he tests a variety of powders, ascertaining each barrel’s particular preference: “In the last few years I have tried N140, N150, H4895, and Varget. I think they are all good powders for F-TR and the 200.20X bullet. This year I was using Varget. At the 2018 SWN I placed 4th with H4895, in 2019 SWN I got 2nd with N140. I find what powder my particular barrel likes best. I also test CCI BR4 and Fed 205M to see which my rifle likes best. This year I was using Fed 205M. I have been using Lapua Palma brass and it seems to last forever.” Peter full-length sizes with a Redding bushing FL die. He seats his Berger bullets with a Wilson inline seater.
Q & A with Peter Johns, F-TR Ace
Q: What was your biggest challenge at the 2020 Berger SW Nationals?
Peter: I think the biggest challenge was staying focused on conditions. I think the hardest thing for me to do is to stop shooting when the wind conditions are out of my ability to call accurately. I focused hard on this aspect of my game this year and it has paid off. This match is super well run and staff does an excellent job which allows the shooters to maintain their focus.
Q: What gear/hardware items give you an edge over the competition?
Peter: The Kestros BR stock (below) is not used by many F-TR shooters and I think it gives me a huge advantage over the competition. This stock fits me perfectly and tracks in such a manner that I can shoot fast and accurately when conditions are right.
Q: What is your advice for newcomers in F-Class and Long Range competition?
Peter: Go to a top gunsmith building F-Class rifles and do what he says. Competition is the best way to get better. So shoot as many matches as you can. Find top shooter rivals and strive to beat them.
Q: Do you have any specific Gun Handling Tips for F-TR shooters?
Peter: I shoot better with a really light grip and cheek pressure. I can shoot well with a heavier grip and cheek pressure but when the tension of a big match is going my pressure will vary and cause poor accuracy. The most consistent I can shoot is with light gun handling. I also focus on trying to watch the bullet hit through the scope to ensure good follow through and this prevents me from jerking the trigger. There are a bunch of ways to hold a rifle that have proven to be successful. I think a shooter needs to test and find what works best for them.
Q: What do you like most about F-Class and Long Range competition?
A. I really like technical things. F-Class is right in my wheel house for technical stuff. Also, the people in the shooting world are top notch. I enjoy talking with other shooters.
Q: Do you prefer individual events or team matches?
Peter: I prefer the team matches by far because it is a social event with collaboration and there is a lot more pressure. I put a lot of effort into learning the wind for the team matches which in the long run helps me with individual matches.

Overcoming Serious Injury in U.S. Navy to Become a Top-Level Marksman
Peter Johns is a U.S. Navy veteran, rank Chief (E7). In 2006, during his duty aboard the U.S.S. Nimitz, Peter sustained very serious and extensive burns in a massive electrical fire. Showing great strength of character, Peter went through a tough, 4-year program of surgeries and rehab. The photo below shows Peter doing therapy during his recovery process.
Peter tells us: “As many of you know I was badly burned on board the U.S.S. Nimitz in 2006. That has limited me in my ability to compete in physical activities that I used to enjoy but F-Class has filled the gap for my competitive nature. I medically retired from the Navy as a Chief (E7) in 2010 after four years of surgeries and physical therapy. I was very surprised to find how accepting and nice people have been in the shooting community. I think the shooting community is comprised of the best people in the world.”
An accurate, self-loading .22 LR rifle, such as this Volquartsen, is our gun of choice for speed shooting with rimfire reactive targets.
Reactive targets offer “instant gratification” — with every hit your target moves, spins, or falls. Shooting reactive targets with a rimfire rifle is fun AND affordable. The price of .22 LR rimfire ammunition has been pretty stable recently, so you can still get very decent rimfire ammo for well under $5.00 a box, such as CCI Blazer ($4.29/box) and Aguila Super Extra ($3.99 to $4.19/box). Now priced at $3.99 for 50 rounds, the Aguila Std. Velocity is just 8 cents a round! At that price, you can shoot every weekend.
Rimfire Know Your Limits Target Rack Challenge Targets offers the popular Know Your Limits (KYL) rimfire target for $159.00. This KYL target has become popular for NRL22 and PRS Rimfire shooters. Start on the left by engaging the 2″ round target and work your way to the right. Each shot gets progressively harder as the target sizes decrease. With each solid hit, the target plate will spin giving providing hit confirmation. The target rack easily breaks down for transport in a couple minutes.
Make Your Own Shooting Gallery with Reactive Rimfire Targets
For .22 LR fans, the folks at Action Target have created a whole series of steel rimfire targets. Much lighter than their centerfire counterparts, these rimfire targets are easier to transport and easier to set up. With this wide selection of reactive targets, you can create your own shooting gallery.
Rimfire Dueling Tree
Rimfire Spinning Jack
Rimfire Plate Rack
Rimfire Buffalo
In this video, Michael Bane reviews Action Target’s line of rimfire targets, which includes plate racks, spinners, dueling trees, and more. As Michael explains: “This line of targets is very well thought out. For example — dueling trees are a lot of fun. But a centerfire dueling tree weighs a lot, it’s hard to cart it around. A rimfire dueling tree is easy to set up, easy to carry around.”
New PT Target “Walks” When Hit
Action Target has a cool reactive target that doesn’t even need a stand or base. The patent-pending PT Twist rests on the ground, and flops over or “walks” when hit. Constructed from a single piece of 3/16″-thick A514B steel, the PT Twist has no welds or bolts to break or ricochet. Watch the PT Twist in action:
A few seasons back, Forum member Rick from Louisiana (aka RMulhern) rigged up a fantastic target for long-range shooting. Rick, a long-time competitive Palma shooter, had a large 72″x72″ steel target fabricated with two separate center rings that are equivalent to the official paper Palma/Creedmoor target. He says he’s “shot a lot of Palma on that target, as well as lots of Black Powder Cartridge (BPCR) rounds”. The big steel target works great when Rick shoots his Sharps 45/110 BPCR at 800 to 1000 yards. The large steel background (painted white) helps Rick see and hear his hits. If you understand the high-arching trajectory of 500+ grain projectiles shot from a 45/110, you know it can take a few rounds to get Point of Impact dialed in.
Rick reports: “These are two of my favorite rifles to shoot: a M1874 Shiloh Sharps in caliber 45/110 (2 7/8) made in Big Timber, Montana by Kirk Bryan and family. The other is a 6.5×47 Lapua on a blue-printed M700 action with 1:8.5″-twist Krieger barrel and F5 McMillan Tactical stock. Many of the shooters that take up BPCR have a tendency to get away from their smokeless powder rifles in favor of the blackpowder game. Frankly I have the best of both worlds as I enjoy shooting both (smokeless and BPCR), although I must admit that I probably spend the majority of my time on the range with the Sharps rifles these days.” (Rick’s pretty good with his Sharps by the way — he recently shot a 95, 96, and 100 (clean) for 3×10 shots at 800 yards.)
Gongzilla: $1000 Worth of Steel with Three Plate Layers
Rick tells us: “Here’s the deal — everything is steel! The large plate is 72″x72″ and the black bull is 44″ diameter. The 20″-diameter central white bull is made from 1/2″-thick AR400 bull-dozer plating. That’s the same size as the regulation Palma/Creedmoor paper target. The white square and black bull are 3/8″-thick mild steel. Plates are off-set 2″ from each other. I welded a 2″ length of square tubing to the back of both plates and the bolt slides through and is attached to the large plate. I used 2 3/8″ upset tubing (oil field pipe) for the holder framing.” Rick says he invested about $1000.00 in metal for the target, but that was 15 years ago. Today the steel would be much more expensive.
Rick says the AR400 armor plate in the center bull is very strong: “You can shoot a .338 Lapua Magnum at 200 yards and it won’t damage the center bull”. The mild steel works well for the cast bullets Rick uses with his Sharps 45/110. Also, Rick says the mild steel is rugged enough for 6.5mm and .308 hollowpoint match bullets, if you’re at least 500 yards away. However, Rick told us, “If I would make [the target] again, I would make the black bull AR400 as well. [That way] you would never have to worry about big dents or beating the plate up at any distance. The AR400 is very tough steel. You can shoot a Sierra or Lapua HP bullet and they will just splatter.”
Rick told us: “I built this target with off-set clanger plates. The white clanger is AR400. Bullets just splatter!” Does he worry about hitting the bolt head? Not at all. Rick says: “When I hit the bolt head, I break my arm patting myself on the back!”.
Some custom barrel makers are now honing barrels (after drilling) to improve bore diameter uniformity, smooth the interior finish, and reduce barrel lapping times. For years, large-scale manufacturers of hammer-forged barrels have employed honing. Now the process is being used by smaller, “boutique” barrel-makers. This article explains how and why barrel honing is done. Take the time to watch the video. For anyone with an interest in barrel-making, this video from Sunnen Products Co. is an eye-opener.
Barrel Honing Process Demonstrated (Worth Watching!):
For custom barrel makers, honing is a time-saver and cost cutter. A few minutes on a honing machine can cut lapping times in half, leaving a cross-hatched surface finish in single or low double-digit Ra. Honing is the same process used to make diesel fuel injectors with bore roundness and straightness controlled to fractions of a micron (<0.000040"), with surface finish Ra ≤0.15 µm (6 µin).
A key manufacturing process used for hammer-forged barrels is now getting attention from the makers of custom button-rifled barrels. This process is precision bore-honing. Honing produces a high-quality bore surface fast, which is critical to hammer forging. (Why is honing so important with hammer forging? Surface finish is the one feature of the barrel that cannot be controlled in hammer forging. Surface imperfections in a barrel blank tend to be amplified as the blank is formed on the rifling mandrel. And if the bore is chromed afterwards, imperfections in the surface finish become even more obvious.)
Honing dramatically improves bore diameter size uniformity and accuracy, surface finish and roundness throughout the length of the barrel. It can certainly be used in place of a pre-rifling lap. The chief difference between a lapped and honed bore is the direction of the finish lines in the bore. Honing leaves fine spiraling crosshatch lines, while a lap leaves lines going longitudinally in the bore. After rifling the manufacturer can remove the crosshatch finish with a quick lap if desired. Honing is fast, accurate, and can be automated. Its surface quality and geometry can duplicate lapping, except for the longitudinal lines of the lapped finish.
In 2015 Frank Green of Bartlein Barrels told us: “We worked with Sunnen and we did all the initial testing on the prototype machine for them. The machine works great! We ordered and received … a new manufactured machine with the changes we wanted on it and [subsequently] ordered a second one.”
The Sunnen hone secures the barrel blank in a 3-jaw chuck, with honing oil pumped into one end while the tool works from the opposite end. Sunnen’s specialized Long Bore Tool uses metal-bond diamond or CBN superabrasives to quickly remove reamer marks, waviness, tight spots and other imperfections left by upstream processes.
Sunnen states that: “Honing is an ideal replacement for hand-lapping barrel blanks before rifling. It quickly removes reamer scratches and surface waviness without labor-intensive hand lapping. By producing a consistent bore diameter (±0.0001″ or less), parallelism, roundness and surface finish end to end, honing yields more consistent performance from rifling buttons and cutters, resulting in a constant groove depth. The ideal bore geometry reduces distortion of the bullet shape.”
Computer-Controlled Bore-Honing
Honing can be done with great precision through the use of advanced, computer-controlled honing machines. Sunnen Products Company offers an advanced machine for .17 to .50-caliber barrels (see control panel below). The spindles on this machine can correct bore size imperfections so small only an air gauge can measure them. The consistency this allows improves bore uniformity, which, in turn, produces more accurate barrels for the precision market.
Sunnen Products Company is the world’s largest vertically-integrated manufacturer of honing systems, tooling, abrasives, coolants, and gauging for precision bore-sizing and finishing. Sunnen’s customers include manufacturers of diesel and gas engines, aerospace components, hydraulic components, oil field equipment, and gun/cannon barrels.
