What kind of accuracy do you think is possible from a rimfire benchrest rifle? If we said 0.44 MOA you might not be surprised, thinking this was at 50 yards. But how about 0.44 MOA accuracy at TWO HUNDRED yards. Now that’s impressive. Consider this — at 200 yards, a 10 mph crosswind will push that little 40gr bullet 15.3 inches. Here’s the story, which comes from the Land Down-Under, Australia.
A few seasons back, Australian John Lavaring shot a group at 200 yards that would make most centerfire shooters proud. The five-shot group, with all shots in the center 10-Ring, measured just 0.93 inches. That works out to 0.44 MOA at 200 — mighty impressive for a .22 LR. Recorded at a Rimfire Fly Shoot benchrest event in Canberra, Australia, this 200-yard target set two new Australian SSAA National records! John was using ELEY Tenex ammunition.
Congratulations to John Lavaring for a spectacular demonstration of how well a rimfire rig can shoot — even at 200 yards. We rarely shoot our .22 LR rifles past 50 meters. Maybe it’s time to start a Rimfire ELR series, with targets at 200 or even 300 yards. What do you think of the Rimfire ELR idea? Leave comments below.
Anschutz 54 Benchrest Rig
The rifle was a Anschutz model 54 Match in a custom benchrest stock. John’s record-setting rig features a barrel block, which you can see forward of the action. Scope is a Bausch & Lomb BR model. We don’t have the round count on Lavaring’s barrel, but good rimfire benchrest rifles can often get 10,000 rounds (or more) of accurate life.
Rimfire Ballistics at 200 Yards
Some folks may be wondering about .22 LR ballistics at 200 yards. Well, with a 25-yard zero, the 200-yard drop for John’s 40gr Tenex ammo is 54 inches, assuming 0.145 G1 BC and 1085 fps muzzle velocity per ELEY website. And at 200 yards, a 10 mph crosswind will push that little bullet 15.3 inches! We’re told the winds were pretty tricky when Lavary shot his record group. This makes his achievement all the more impressive — we have to admire John’s wind-reading ability.
This ELEY ammo has proven to be exceptionally accurate. Here is a short video showing TEN rounds of Tenex shot from a machine rest with target at 50 meters.
The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).
So how does powder grain shape affect pressure and muzzle velocity?
In general, it can be said that powder that burns progressively achieves a desired muzzle velocity at lower maximum pressure than a powder that burns neutrally, not to mention a degressive powder. As grain size increases, the maximum pressure moves towards the muzzle, also increasing muzzle blast. Muzzle velocity and pressure can be adjusted by means of the amount of powder or loading density, i.e. the relationship between the powder mass and the volume available to it. As the loading density increases, maximum pressure grows.
All Vihtavuori reloading powders are of the cylindrical, single-perforated extruded stick type. The differences in burning rate between the powders depend on the size of the grain, the wall thickness of the cylinder, the surface coating and the composition. Cylindrical extruded powders can also have multi-perforated grains. The most common types are the 7- and 19-perforated varieties. A multi-perforated powder grain is naturally of a much larger size than one with a single perforation, and is typically used for large caliber ammunition.
Other types of powder grain shapes include sphere or ball, and flake. The ball grains are typically used in automatic firearms but also in rifles and handguns. The ball grain is less costly to produce, as it is not pressed into shape like cylindrical grains. Flake shaped grains are typically used in shotgun loadings.
Web thickness in gunpowder terminology means the minimum distance that the combustion zones can travel within the powder grain without encountering each other. In spherical powders, this distance is the diameter of the “ball”; in flake powder it is the thickness of the flake; and in multi-perforated extruded powders it is the minimum distance (i.e. wall thickness) between the perforations.
The burning rate of powder composed of grains without any perforations or surface treatment is related to the surface area of the grain available for burning at any given pressure level. The change in the surface area that is burning during combustion is described by a so-called form function. If the surface area increases, the form function does likewise and its behavior is termed progressive. If the form function decreases, its behavior is said to be degressive. If the flame area remains constant throughout the combustion process, we describe it as “neutral” behavior.
The cylindrical, perforated powders are progressive; the burning rate increases as the surface area increases, and the pressure builds up slower, increasing until it reaches its peak and then collapses. Flake and ball grains are degressive; the total powder surface area and pressure are at their peak at ignition, decreasing as the combustion progresses.

John Nosler lived 97 years, passing in 2010. During his long lifetime, John was an iconic figure in the shooting and hunting world. Considered a true pioneer in bullet and ammunition design, Nosler developed the famous Partition bullet in the 1940s. Born on April 4, 1913 in Brawley, California, John built his business from scratch. He founded his bullet company in 1948. He was considered to be one of the great innovators whose designs helped create the premium bullet category and influenced ammunition manufacturers worldwide.
Moose-Hunt Inspires Partition Bullet Design
While hunting in Canada, John experienced a bullet failure on the hide of a mud-caked bull moose. He then began developing a revolutionary new projectile, which he called the “Partition”, because of the barrier that separated the bullet into two sections. One year later, John and a friend traveled back to British Columbia with his new Partition bullets, which were designed to provide deep penetration and expansion. The men bagged two moose with two shots, and the rest is history.
NRA Golden Bullseye Pioneer Award
In recognition of his contribution to the shooting sports industry, John was the unanimous choice for the inaugural 2007 NRA Golden Bullseye Pioneer Award. The award was the highlight of a long and fruitful career. Even though he officially retired in 1988 when his son and daughter-in-law, Bob and Joan Nosler purchased the company, John still managed to come to the office on a daily basis until his health declined.
Today, John’s son Bob Nosler still presides over the company as president and CEO of Nosler, Inc., based in Bend, Oregon. Along with bullets, the company now produces cartridge brass, loaded ammunition, and hunting rifles.

CLICK HERE to find the Going Ballistic book on Amazon. It is offered in paperback for $19.99 or hard-cover for $53.76. There is also a $6.99 Kindle edition.
John Nosler remained an avid hunter and shooter even late in life. Gary Lewis recalled that, at age 92, John Nosler attended the opening of a new shooting range outside Bend, Oregon. Even in his nineties, Nosler managed to drill two shots inside nine inches at 1000 yards. John Nosler leaves a legacy that will benefit hunters and shooters’ nationwide. The John A. Nosler Endowment of The NRA Foundation, sponsors the NRA’s Basic Rifle Training Program which instructs novices in safe rifle handling.
Just last week hundreds of F-Class shooters competed at the 2026 Southwest Nationals in Phoenix, Arizona. The vast majority of F-TR shooters had rifles chambered for the .308 Winchester cartridge (7.62×51), but F-TR rules also allow the .223 Rem (5.56×45). There are some advantages to the smaller .223 Rem round — there’s notably less recoil, bullets and brass are significantly cheaper, and a lot less powder is required. For those who are considering campaigning a .223 Rem F-TR rifle, this story explains how an accurate .223 Rem load was developed. This load development was done by a father for his daughter who was getting started in F-Class competition.
Dad builds an F-TR Rifle for his Daughter and Develops Load
Jeremy Rowland decided to put together an F-TR rifle for his eldest daughter, who enjoys competitive shooting. For his daughter, Rowland chose the .223 Rem option because it has less recoil and components are less costly than the .308 Win. Here is Rowland’s account of how he developed a .223 Rem load. For more details (with data charts), read Jeremy’s FULL STORY on Sierra Bullets Blog.
Journey to Find a .223 Rem F-Class Load
by Jeremy Rowland, Reloading Podcast
My oldest daughter has been to several matches with me, and has even competed in several, using her .243. [A few seasons back] I decided, she would compete with a .223 Rem in F-TR. Looking for a good starter rifle, I settled on the Savage Axis Heavy Barrel since it has a 1:9″ twist. This would be a great little rifle for her to learn on. The rifle was shot unmodified, as it came from the factory. A Sinclair F-Class Bipod w/micro elevation adjustment was fitted to the front.
Next came finding the components I wanted to use for her match loads. After spending hours and hours running numbers on JBM stability calculator as well as in my iPhone Ballistic AE app, the 69 gr Sierra Tipped MatchKing® (TMK) looked really good. So that’s what I decided to go with. I jumped in head first and ordered a bulk pack of the Sierra 69 gr TMKs. I had settled on Hodgdon CFE 223 powder since it shows good velocity. I decided to go with once-fired Lake City brass with CCI BR4 primers.
Next came the testing. I decided to run a ladder test (one shot per charge from min to max looking for the accuracy node). The ladder test ranged from 23.5 grains to 25.6 grains, in 0.3 grain increments.
Bullet: 69 gr Sierra Tipped MatchKing®
Case: Lake City (mixed years, sorted by case capacity)
Primer:CCI BR4
Powder: Hodgdon CFE 223 (one round each from 23.5 to 25.6 grains)
Cartridge OAL: 2.378″
Base to Ogive: 1.933″ (.020″ off lands)
After his ladder test, Rowland settled on a load of 25.2 grains of Hodgdon CFE 223. He then fine-tuned his load with different seating depths: “I loaded up 5 rounds each at .020″ off lands, .015″ off lands, .010″ off lands, and .005″ off the lands. Here are the results from the best group for OAL/Ogive fine tuning. As you can see, I think I’ve found a winner in these 69 gr Sierra Tipped MatchKings.”

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.
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).
