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. Sunnen employs more than 600 people worldwide.
We really like rimfire revolvers here at AccurateShooter.com. A good .22 LR wheelgun will be fun, accurate, reliable, and inexpensive to shoot. Rimfire revolvers also offer much less recoil and noise than a centerfire pistol. Your Editor has owned a Smith & Wesson Model 617 for over 20 years. That old S&W has probably fired more rounds than all the other handguns I own, combined — yet it still runs flawlessly and still delivers excellent accuracy.
Ruger offers a big stainless .22 LR wheelgun to compete with the S&W Model 617. This rimfire wheelgun is based on Ruger’s trusted GP100 platform. The Ruger GP100® chambered in .22 LR is a good firearm — strong, versatile, and intelligently engineered. A while back, the late Jeff Quinn of Gunblast.com tested the Ruger revolver and gave it high marks: “It’s a good hefty gun [42.6 oz.], but not overly large or heavy for a good trail gun. It’s just a really nice, well-made revolver from Sturm Ruger.” The gun Jeff tested had a 3.7-lb Single action trigger pull and a 9.8-lb Double action pull.
The .22 LR GP100 features a windage and elevation adjustable rear sight with a white outline, a light-gathering fiber optic front sight and the original full-size GP100 rubber grips with hardwood inserts. With all stainless-steel construction, the rimfire GP100 is easy to maintain. Just keep the cylinder chambers and barrel clean and this gun should run forever.
This Review of the .22 LR GP100 by Hickok45 has over 6.9 Million Views:
The 10-shot Ruger GP100 in .22 LR is a durable, well-engineered wheelgun. Ruger’s engineers optimized the GP100’s innards to deliver a smooth double-action pull: “The new GP100 has an improved fire-control system that uses a lighter mainspring than previous Ruger double-action .22 LR revolvers … we’ve done a lot of development on the firing pin location and geometries so that we’re able to put a lighter trigger pull in this gun than you would find in other .22 LR [handguns]. We’ve got a half-underlug barrel, and it’s a smaller diameter so the gun balances real well. We’ve added a narrow-spur hammer and a smooth trigger.”
Do you have trouble seeing your bullet holes (on paper) when shooting past 400 yards? That’s a common issue even with premium ($2000+) high-magnification scopes. Here’s a target that solves that problem. A hit creates a larger black circle “halo” that’s much more visible than a plain bullet hole, making this target ideal for use at longer range (500 yards and beyond).
The 12″ square Birchwood Casey white background Sight-In Target displays a black “halo” around each hit (like the yellow circle on a conventional Shoot-N-C). Larger than bullet diameter, the “halos” can be easily seen with a high-magnification scope at long range (see video below). The self-adhesive target features five diamonds with contrasting red box centers. For precise aiming, you can position your cross-hairs to align with the corners of the boxes. Or, you can put a target dot sticker in the middle.
This video shows Black Shot Halos on white background:
While we envision using this target with optics at long range, Birchwood Casey says that open sights show up well against the white background, making these targets well-suited for indoor ranges or use in low light conditions.
This reactive white background grid target has 5 aiming points and a 1-inch grid overlay for easy, precise sight adjustments. It comes with target pasters to cover up the bullet holes (halos). The White/Black Shoot-N-C 12″ Square GRID Sight-In Targets come in 5-packs with target pasters for $9.49 from MidwayUSA or $8.69 from Palmetto SA. If you prefer reactive Shoot-N-C circle targets, there is an 8″ circle target, a 12″ circle target, and a large 17.5″ circle target with red diamond center (photo right). These all have bullet pasters.
High-Viz Option — Yellow on Black Grid with Yellow Halos
If you prefer seeing ultra-high-contrast yellow/green “halos” for your hits, Birchwood Casey also makes adhesive grid targets with five yellow-edged diamonds. Red circles provide precise aiming points in the middle of each box. You can quickly estimate group size or dial-in your zero using the hi-viz yellow 1″ grid lines. These yellow-on-black targets are available in three sizes: 8″ square, 12″ square, and 17.25″ square. These yellow-on-black grid targets start at $9.99 for an 8″ six-pack.

Do you have some ammo that got loaded incorrectly, perhaps with the wrong powder? Then you’ll want to disassemble the ammo for safety’s sake. You can use an impact puller to do this task, but if you have more than a dozen rounds or so, you may prefer to use a collet-style bullet puller. These work very quickly and positively, making quick work of big jobs. The efficiency of the collet-style puller is worth the investment if you frequently disassemble ammo. These devices retail for under $35.00 (collets sold separately). Normally, you’ll need a specific collet for each bullet diameter. But collets are not that costly, so this isn’t a big deal, particularly if you only load a few calibers, such as .223, 6mm, and .308.
Hornady and RCBS use different mechanisms to tighten the collet around the bullet. On the red lever Hornady Cam-Lock Bullet Puller, a lever-arm on the top of the bullet puller serves to tighten the collet around the bullet. Simply rotate the lever from the vertical to the horizontal position to grab the bullet. Lower the ram to remove the case. The bullet will drop out when you return the lever arm to the vertical position. This is demonstrated in the video below:
Hornady Cam-Lock Bullet Puller Demonstrated
Collet bullet-pullers resemble a loading die with a lever or handle on the top. They screw into a standard reloading press. Hornady and RCBS both make collet-style bullet pullers. They use the same basic principle — the device tightens a collet around the bullet, and then the bullet is separated from the case by lowering the press ram. NOTE: Collet pullers may leave small marks on your bullets, unlike impact (kinetic) pullers.*
Like the Hornady tool, the RCBS Bullet Puller employs a collet to grab the bullet. However, the RCBS tool tightens the collet in a different way. The head of the RCBS tool is threaded internally. By rotating the lever arm clockwise in a horizontal circle you squeeze the collet around the bullet. To remove the bullet, after lowering the press ram, simply spin the lever arm back in the opposite direction. The use of the RCBS tool is demonstrated in these two videos:
RCBS Collet Bullet Puller Demonstrated:
WARNING: When removing bullets from loaded cartridges, always make sure there are no obstructions or debris in your shell-holder or under the loaded round. NEVER engage a primer seating accessory on your press when working with loaded rounds. You can cause a round to discharge by contacting the primer! Also, we recommend you keep your head and torso away from the bullet puller tool at all times.
*By contrast, impact pullers rarely mark bullets, particularly if you put a little bit of foam or paper wadding in the closed end of your impact puller. When dismantling loaded rounds, powder kernels can get trapped in the wadding, so you should remove and replace the wadding before changing to cartridges loaded with a different powder type (assuming you intend to save the powder).
Ever wondered how the parts inside an AR15 work together? Just exactly how does the reciprocating bolt carrier feed rounds from the magazine? How do the elements in the trigger group work and reset after each shot? How does the gas system bleed gas from the barrel and operate the bolt carrier? These and other questions are answered in this eye-opening video from 45Snipers. Using “cutaway” 3D computer animation, this 5-minute video shows all features of an AR15 inside and out. This fascinating firearms animation allows the viewer to look inside the upper and lower receivers, into the bolt carrier, chamber, barrel, and magazine.
This video starts off slow and has annoying background music, but it is well worth watching if you own or shoot any AR-platform rifle. It illustrates all the key operations during the charging, loading, firing, and ejection processes. The cutaway animation shows how rounds are stripped from the magazine and then chambered. It then shows how every part of the trigger group works, and how the firing pin strikes the primer. You can even watch the bullet move down the barrel before the empty shell casing is removed from the chamber and tossed out the ejection port. Here are sample frames from the video:

Even with high-quality brass from Lapua, Peterson, Norma, Alpha and RWS, occasionally you may find one or two cases per box which have a small flake or obstruction in the flash-hole. This will appear like a thin crescent on one side of the flash hole (see photo). You should inspect ALL new brass before loading to identify any pieces with a partially-obstructed flash hole. It’s a good idea to remove any flake or thin crescent left as an artifact of the flash-hole forming process. Because the flash-hole itself is normally centered and of the correct diameter, it is not necessary to ream the flash-hole to a larger diameter. All you really need to do is remove the small obstruction(s). This can be done quickly with inexpensive tools.
Use a Small Pin Vise to Remove Flash-Hole Obstructions
Folks have asked if there is a tool that can remove obstructions from a Lapua small, BR-sized flash hole without opening the hole size. The Lapua PPC/BR flash hole is spec’d at 1.5mm, which works out to 0.059055″. Most of the PPC/BR flash-hole uniforming tools on the market use a 1/16″ bit which is nominally 0.0625″, but these often run oversize — up to 0.066″.
If you want to just clear out any obstructions in the flash hole, without increasing the flash hole diameter, you can use an inexpensive “pin vise” with an appropriate drill bit. For $5.39, Amazon sells a 10-piece set of cobalt steel 1.5mm drill bits that match the Lapua flash hole exactly. Other vendors such as Ace Hardware offer a #53 pin vise drill bit that measures .0595″ or .060″ (depending or source). An 0.0595″ (1.51 mm) bit is close enough. You can find pin vises and these small-diameter drill bits at hobby stores.
For quite some time, Sinclair Int’l has sold a similar device for small (PPC and BR-size) flash holes. Like the 749008617 unit for large flash holes, the 749005418 Reamer for small flash holes works from the outside, so it can index off the primer pocket. It reams to .0625″, and also costs $29.99. The standard dimension for Lapua 220 Russian and 6mmBR flash holes is 1.5mm or .0590″. This tool will permit standard-size decapping rods with .0625″ tips to work without binding. However, note that both Forster and Redding normally supply .057″ decapping pins with their PPC and BR dies. So, it is NOT necessary to ream your Lapua BR/PPC flashholes, unless you prefer to do so for uniformity. It IS, however, a good idea to check BR/PPC flash holes for burrs before loading the first time.
Redding also makes a handy tool that deburs and uniforms small flashholes, but works from the inside of the cases. This Redding tool has a bushing that fits in the case neck for proper alignment.
NOTE: If you purchase the Sinclair Flash Hole Reamer tools, we recommend you mic the cutter tip before you process a bunch of cases. Sometimes a tip comes through that is oversize. This will ream the flash holes larger than you may intend.
For this 2026 Super Bowl Sunday, we celebrate the beauty of highly-figured wood with a collection of custom rifles. In our Shooters’ Forum, there is a long-running Gun Glamour thread that showcases many beautiful wood-stocked rifles. Today we feature some very handsome rifles from that Forum Thread as well as other rifles we’ve featured in the Daily Bulletin.
Two F-Open Beauties with Walnut Laminates
Cerus-stocked Special from Cigarcop
Forum member Keith W. (aka “Cigarcop”) of KW Precision LLC is a talented riflesmith whose projects display outstanding finish work and attention to detail. Keith does some of the best bedding work we’ve ever seen. Back in 2018, Keith built a stunning .284 Win F-Class rig for a shooter in Delaware. It’s a beauty, that’s for sure.
Check out the stunning Cerus F-Open stock. This features multiple laminations with highly-figured Walnut on the sides. This certainly ain’t your “off-the-shelf” laminated stock. This just shows the beauty that can be achieved with carefully-chosen lamination layers (plus 12 coats of clear).
This beautiful F-Open rig features a laminated wood stock with stunning figured walnut on the outside.
Another KW Precision F-Open Beauty
Here’s another stunning F-Open rig crafted by Keith of KW Precision. This features a BAT M action with BixN’Andy trigger. The 1:9″-twist Brux barrel is chambered in 7-6.5 PRC and fitted with a Cortina V2 Tuner. The handsome laminated Dennis Ray stock carries a Hart R.A.D. 2A recoil reduction system.
A Beauty for the Boss (of Grizzly.com)
This F-Class rifle belongs to Shiraz Balolia, Chairman/CEO of Grizzly Industrial. Shiraz finished the stock himself: “I installed the bottom wider track for my rear bag and also carved out the finger grooves in the grip. The blank was quite long so I cut off approximately two inches from the front end of each stock and also deepened the large tracking cavity under the fore-end. I went ahead and inlaid my name in Mother-of-Pearl on the Walnut stock.” The stock was then sent to Sims Guitar Finishing for clear coating with “wet look” finish. This rifle is chambered for the .300 Shiraz wildcat, an improved .300 WSM.

Beautiful Rifles from our Forum Gun Glamour Thread
Here are a variety of handsome wood-stocked rifles from our Forum Gun Glamour thread. In that thread, member Kurz posted a dream gun owned by a friend in England. Kurz included a quote from a book created by the rifle’s owner: “There, with my father’s words ringing in my ears, I shall take that ‘step forward’ and order a perfect machine based on the Mauser ’98 action, built from metal and wood by master craftsmen who truly understand that ‘reliable’ and ‘mechanical integrity’ have as much relevance today as they did all those years ago.”
A gun can “shoot dots” and still be handsome. Here is a short-range benchrest rifle with a stunning, exhibition-grade Walnut stock. Forum member Josh B found this beauty.
Forum member JRS submitted a stunner from Europe. This beauty features a truly exquisite piece of wood with elaborately engraved receiver. It also has escutcheons and special metal work on the grip.
Lever-action Falling Block rifles can be beautiful too. This one features a color case-hardened receiver and handsome two-piece fancy wood stock. This was submitted by Forum member Kurz who notes: “Besides exhibition grade walnut, I like the variations available in spalted maple for rifle stocks.”
Here is member Oldduc’s Stevens 44 1/2, .38-55 Black Powder Cartridge Rifle, with an extra .218 Mashburn Bee barrel. Very nice blueing along with the figured wood stocks and fore-arms.
A competition rifle must be “performance first”. But that doesn’t mean they can’t be handsome too. Forum member XTR’s rifle, an F-TR rig, features Maple wood with Bubinga tips.
And wood can work for Benchrest rifles too, when cleverly fashioned in thin carbon-reinforced laminates. Photo from member mdman352.
“Wood is Good” — as demonstrated by all the rifles showcased above. In the photo below, master stock-builder Doan Trevor handcrafts a highly-figured wood stock.
Many Remington 700 rifle owners swap out the factory trigger. This is not a difficult task, but you need to follow the proper procedure so you don’t damage any important parts during installation, and so that you don’t interfere with the operation of the bolt and safety. This Do-It-Yourself video from Brownells explains and demonstrates, step by step, how to safely and correctly replace your Remington 700 trigger. This installation video covers the common methods used to install most of the popular after-market Rem 700 triggers. Importantly, the video also shows how to function test after installation, and how to make sure your safety is working properly.
Many Rem 700 owners fit Timney triggers to their rifles.

The 2026 Southwest Nationals will be held at the Ben Avery Shooting Facility in Phoenix, Arizona on February 11-15, 2026. We know many of our readers will be traveling by air with their rifles next week to compete at the SW Nationals in Arizona. Here is a helpful article from Team Savage Shooter Stan Pate. This covers how to ship your rifle safely, and then re-establish zero properly when the gun is reassembled after transport. This is one of a series of Shooting Tips articles in the Savage Blog.
Traveling with Firearms — Important Advice
Traveling with firearms can be stressful. You must comply with multiple regulations and then trust your expensive guns to airline baggage handlers. And after arrival you’ll need to put your rifles back together and confirm the zeros. This article offers helpful travel advice from Team Savage shooter Stan Pate. Pate has traveled the globe competing with match rifles. Here he shares his tips for making trips easier on you and your firearms.
Easier Air Travel With Firearms
TSA isn’t nearly as careful with your rifles as you are. Proper storage before sending your firearm up a conveyer belt and into the belly of a plane is critical. Stan Pate spends lots of time each year traveling the skies and has devised a system for keeping his rifle safe when going to and from.
“Never travel with your firearm completely assembled,” Pate cautions. “A fully assembled firearm is much heavier [as a total unit] than one that has been broken-down and stored [in separate sections]. More weight creates more in-the-case movement, which can result in damage. I learned this the hard way years ago. My rifle was actually broken in half when traveling to an international competition. Record your torque settings, use those settings during reassembly and your return to zero should be no problem.”
“Be sure to check on current TSA rules and regulations before travel to be aware of any changes that may effect how you pack your rifles,” says Pate.
Rifle Reassembly and Resetting Zero
The quicker you can reestablish your zero, the quicker you can relax and stop worrying about if your rounds are going to hit their mark during competition. Pate, over the years, has developed a system for rifle reassembly and getting back to zero as quickly as possible. While his torque settings may not be the same as yours, the process can still be used.
“The barreled-action goes back on the stock, and then I tighten all three receiver screws finger tight,” says Pate. “Next, I tighten the front two receiver screws down to 35-inch pounds. The rear receiver screws on this particular rifle likes 15-inch pounds. [Note: Proper torque settings will vary with your action and stock type. Most actions have TWO screws, not three.] Scope attachment comes next, and I follow manufacturer settings when tightening it down. All that’s left to do now is go zero your rifle.”

PMA Tool offers lightweight yet sturdy cleaning cradles that are handy, affordable, and easy to transport. PMA’s popular single-gun cradle, priced at $119.95, is ideal for benchrest and F-Class rigs. It measures about 17″ in length and weighs about one pound. You can choose among 2.25″, 3″, 4″, 5″, and 6″-wide saddles (U-shaped padded supports) to match your forearm width.
PMA also offers an excellent double cradles for $174.95. These twin cradles have 2.5″, 3″, or 4″ saddles, or a combo of 3″ / 2.25″ front saddles. All these cradle types secure your rifle(s) in a muzzle-down position that allows easy cleaning and prevents solvents from running back into the action. The front saddles and all contact surfaces are covered by thick silicone rubber padding which grips the rifle securely yet protects the stock and components from scratches.
These cradles are most commonly sold with a 3″-wide front saddle for Benchrest and F-Open style stocks, or a 2.25″-wide front saddle for rifles with narrower fore-ends such as those found on F-TR, Hunter Class, and varmint stocks. In addition, you can get 4″-wide cradle for the big, long range benchrest rifles.
Double Rifle Cradle is a Smart, Versatile Design
PMA’s double rifle cleaning cradle was was designed from the ground up to work perfectly for two rifles side-by-side. Using the same tie bar and protective saddles found on the single cradel, PMA widened the base and created new uprights to support the saddles, making the cradle as narrow and light as possible, while retaining all the protective and non-slip features from our single unit.
This PMA Tool double cradle unit is available with twin 3″ front saddles, double 2.5″ front saddles or combination 3″ / 2.25″ front saddle configurations to accommodate different classes of benchrest rifles.
Like the Hornady tool, the
