Extreme Long Range — One Mile Shooting
In this video, Gavin meets with Paul Phillips, an ELR “King of Two Miles” past Champion. Paul explains the features in his .375-caliber rifle designed to shoot to one mile and beyond. Along with a big action to hold the very long cartridge, an ELR rifle needs a special high-angle optics rail to allow the needed elevation. In addition, a long-wheelbase chassis is optimal for greater stability and balance. Recoil is very significant so Paul’s rifle boasts a massive 6-port muzzle brake on the very long barrel (ELR barrels can run 34-36″). For his projectiles, Paul is running Berger’s impressive new 410gr .375 caliber Hybrid Target Bullet (6:25 time-mark).
Peterson Cartridge — How High-Quality Brass is Crafted
Ever wondered how modern, top-quality rifle brass is made? Then watch this informative video from start to finish. It shows how the brass cases are drawn (lengthened) in stages, how the primer pockets and rims are formed, how the shoulders and case necks are crafted, and then how the brass cases are machine-annealed for consistent strength and neck tension.
6x47L Rifle Build with BAT Action & Woox Furiosa Ultra Chassis
Gavin Gear has completed many impressive custom rifles. This handsome rifle is one of Gavin’s best efforts. Chambered for the 6-6.5×47 Lapua wildcat cartridge (aka 6x47L), this rifle has show great accuracy. It boast a handsome black BAT Hammerhead action and a wood/metal composite WOOX Furiosa Ultra chassis. This high-tech hybrid stock/chassis combines wood sections over a full-length, aerospace-grade aluminum skeleton chassis, giving it the “feel” of a wood stock with the strength and stability of a metal stock. Gavin likes the way the stock feels on the trigger hand in particular and the smooth wood cheekpiece is also very nice. Made in Italy, the Furiosa is offered in three versions all with wood sections on the forearm, grip area, and cheekpiece. Choose natural Walnut Brown, Micarta Black, or Midnight Grey.
NEW RCBS MatchMaster Precision Case Trimmer System
At SHOT Show 2026, RCBS introduced the new MatchMaster Precision Case Trimmer system. Developed with Henderson Precision, this is a high-speed, motorized system that trims, deburrs, and chamfers .22 to .30 caliber brass in one step. With a $699.99 MSRP, the MatchMaster trimmer features a 3-way carbide cutter, micrometer adjustment for 0.001″ accuracy, and a brass shavings catcher. It is designed for high-volume reloaders, offering fast, consistent, and automatic case prep. In this video, Gavin shows the features of this new RCBS power tool.
BAT Actions — Insider Look at Manufacturing
Full Story:https://bit.ly/3hD2d11 BAT Machine Co. makes some of the finest custom actions you can buy. Numerous national and world records have been set with BAT actions. To create this 31-minute video, Gavin traveled to Idaho to visit the BAT Machine production center in Post Falls, ID. Gavin talked with BAT’s founder Bruce Thom. The video features extensive footage of advanced CNC machines used to produce the superb BAT actions.
New 6GT Cartridge Brass from Lapua
It’s great that Lapua is now offering 6GT brass. Developed by George Gardner of G.A. Precision and Tom Jacobs of Vapor Trail Bullets, the 6GT was designed to have the efficiency of a 6mm Dasher without the need for case forming. It was also designed with a longer case body so it feeds better from magazines.
Even with the added capacity, the 6GT is still very efficient, and can achieve good velocities with less powder than a 6mm Creedmoor. With outstanding brass now being offered by Lapua, the 6GT becomes a very good choice for PRS/NRL competition, and even mid-range F-class competition. It’s longer than a Dasher case so it runs better in magazines, but it’s still more efficient than a 6mm Creedmoor or .243 Win.
RifleBuilderPro Gunsmithing Program Unveiled
At SHOT Show 2026 Gavin Gear introduced an impressive new software/info system for gunsmiths and gun-building operations. Rifle Builder Pro provides key specifications and data for smithing operations. But it is more than just about machine controls — Rifle Builder PRO will be a subscription-based companion and digital reference library for Precision Rifle Gunsmiths, designed to help them achieve great results in less time. Subscribers will also automatically join an online community full of exclusive resources and support to improve their craft.
Rifle Builder PRO is currently targeted towards precision rifle gunsmiths working on bolt-action rifles but there are expansion plans to include additional types of rifle gunsmithing. At this time Rifle Builder Pro is still in development with a public Beta coming later this year. Sign up for email updates at RifleBuilderPro.com.
Athlon RangeCraft Chronograph (Two Videos)
Athlon’s Rangecraft Velocity PRO Doppler Radar Chronograph is a genuine rival to the popular Garmin. These two UltimateReloader vidoes cover the AThlon’s features, specs, and hardware. Then the video covers the testing process. The new Athlon Rangecraft Velocity Pro Radar Chronograph is an impressive and very affordable compact chrono, selling for $399.99 at most vendors. This employs Doppler radar allowing ultra-accurate velocity readings. Since the unit isn’t triggered by a muzzle blast, it can work with suppressors, muzzle brakes, and other muzzle devices.
The Rangecraft Vel Pro reads velocities between 65 FPS and 5000 FPS. So far field tests have shown that the Athlon Rangecraft chrono is reliable and picks up all shots fired with all types of rifles and pistols (even airguns). However the listed velocities may be a few FPS different than a Magnetospeed or Labradar. The unit includes a compact tripod.

“22 Plinkster” is an avid shooter who has produced a number of entertaining videos for his YouTube Channel. In the video below, he tackles the question “Why Do Misfires Occur in .22 LR Rimfire Ammunition?” This is the most common question posed to 22 Plinkster by his many viewers. He identifies four main issues that can cause .22 LR misfires or faulty ignition:
1. Damaged Firing Pin — The dry firing process can actually blunt or shorten the firing pin, particularly with older rimfire firearms. Use of snap caps is recommended.
2. Poor Ammunition — Some cheap brands have poor quality control. 22 Plinkster recommends using ammo from a manufacturer with high quality control standards, such as CCI and Federal.
3. Age of Ammunition — Rimfire ammo can function well for a decade or more. However the “shelf life” of rimfire ammunition is not infinite. You ammo’s “lifespan” will be shortened by heat, moisture, and humidity. You should store your rimfire ammo in a cool, dry place.
4. Mishandling of Ammunition — Tossing around ammunition can cause problems. Rough handling can cause the priming compound to be dislodged from the rim. This causes misfires.
Preventing misfires is essential if you want to succeed in NRL22 competition and other rimfire competition disciplines run “on the clock”.
The Making of MatchKings — How Sierra Produces SMKs
All Sierra bullets begin life as a strip of gilding metal, an alloy consisting of 95% copper and 5% zinc. To meet Sierra’s strict quality requirements, the gilding metal requires three times more dimensional and quality control standards than is considered standard in the copper manufacturing industry.
A blanking press stamps out a uniform disc and forms the cup that will be drawn into the MatchKing jacket. The cup is then polished and sent to a draw press to be drawn into a jacket that is longer than needed for the future MatchKing, thus allowing for the trim process. Press operators constantly check concentricity to ensures jacket quality. The jackets then go to a trimmer where they are visually inspected again.
After being polished a second time, the jacket travels to the bullet press. In the meantime, 80-pound lead billets are being extruded into lead wire for the cores where great care is taken so that the core wire is not stretched. The core wire is lightly oiled before continuing to the bullet press to be swaged.
The lead core wire and trimmed jacket meet at the bullet press where the first stage forms a boattail on the jacket. The lead core is then formed on top of the bullet press and fed down into the jacket. In one stroke of the press, the MatchKing is formed.
Quality control technicians pull samples from each lot of MatchKings to make sure they meet Sierra’s stringent standards. Samples are then sent to Sierra’s 300-meter underground test range (shown below) to be shot for accuracy on mechanical mounts referred to as “unrestricted return to battery rests” that Sierra designed and built in-house.
After inspection, the bullets are placed in the familiar green box along with reloading labels. They are then shrink-wrapped and shipped all over the world.
Most folks would be very impressed with a centerfire rifle that can shoot a quarter-inch group at 100 yards. But to do that with a rimfire rifle, shooting little .22 LR cartridges, that’s quite an accomplishment. Today’s Sunday GunDay story spotlights a superbly accurate new .22 LR Benchrest gun belonging to Forum member Dave Way. This rimfire tack-driver was crafted by respected gunsmith Alex Wheeler of Wheeler Accuracy. Check out this five-shot group Dave shot once he had figured out his optimal tuner position. That is mighty impressive for a rimfire rifle!
A sub-quarter-MOA group at 100 yards is impressive for a centerfire rifle. But for a rimfire rifle, it is truly stunning. Check it out — this rifle hammers!
I tested three lots of Lapua Super Long Range today. This lot looked really good so I bought a case. It’s a blast shooting this rifle over wind flags. It’s amazing how little wind it takes to move the bullet at 100 yards. I was having to hold off today to finish up groups. That’s when it’s the most fun. — Dave Way
Dave posted in our Shooters’ Forum: “To say I was impressed with the quality of the action and the accuracy of the rifle would be an understatement. I shot five different lots of Lapua Midas, Lapua Long Range, and Lapua Super Long Range ammunition. At 50 yards all the groups were pretty tight. I was shooting in some wind, using flags. One lot seemed to stand out so I put a target at 100 yards and shot three rounds in it as aiming points. I shot three five shot groups with the last 15 rounds of that lot that I had with me. All three groups were under 1/2″ and they were getting tighter as I moved the tuner!”
Above are initial 100-yard, 5-shot groups Dave Way shot with his rifle, while experimenting with different tuner positions. The largest group (on left) was a 0.416″, while the smallest (on right) was 0.296″. The average of the three groups was a stellar 0.369″ (0.352 MOA).
Dave Way treasures this rifle and praised Alex Wheeler’s skills as a gunsmith: “I have never received a rifle from Alex that didn’t shoot incredibly well and this one is no exception. I’m just getting into the .22 world so I don’t know if this is good, great, or excellent accuracy but it seems pretty accurate to me.”
Lot Testing and Tuner Experimentation Pays Off
Here are some initial groups Dave Way shot during initial ammo testing. They are all under half-inch at 100 yards. That’s pretty impressive — but read on. When Dave optimized his tuner position and found a great lot of Lapua Super Long Range .22 LR ammo — his groups got even smaller. Dave notes: “They could have been better but I was just getting used to the trigger and everything.”
Here are a series of three-shot, 50-yard groups. You can see this rifle is quite consistent. This is with five different lots of Lapua .22 LR ammunition.

Three 50-Yard Groups, All Under 0.180″ — That’s Consistency!
With the right ammo, this rig is wicked accurate. Here are three groups shot at 50 yards one after another. Dave shot these three 5-shot groups consecutively while optimizing his tuner: “Working with tuner the last two trips to the range. [It was] very consistent and pretty tight at tuner setting 162. Here are three consecutive 50-yard groups (5 shots each).” The biggest group (at bottom) measured 0.175″ (0.334 MOA), while the smallest group (middle) was a stellar 0.154″ (0.294 MOA) — that’s mighty impressive!
Alex Wheeler Crafted His Own Superb Rimfire Rifle First
Gunsmith Alex Wheeler of Wheeler Accuracy has, over the years, concentrated on ultra-accurate mid-range and long-range centerfire benchrest rifles, along with some stellar long-range hunting rifles. But Alex has started to venture into rimfire shooting. Prior to building the Dave Way rimfire rifle featured here, Alex built a “sister rifle” for himself with similar components. That gun turned out so well that Dave asked Alex to build another. And, as you can see, Dave’s new Wheeler-built rimfire rifle turned out to be a true tack-driver.
Alex credits Dave’s shooting skills: “I don’t think its possible for anyone to send a rifle to Dave that doesn’t shoot. He just has a knack for it. I’m glad I got into the rimfire stuff. I don’t have any interest in rimfire competition but it’s taught me a lot about bench manners and I get a lot more trigger time. It’s a great tool to learn wind flags with as well. It should make me a better centerfire shooter. That was really why I built mine. I normally sell every gun I build eventually and Dave was going to get mine but I said you should start gathering parts, I think I’m keeping this one!”
Lapua Long Range and Super Long Range .22 LR Ammunition
Dave Way had great results with his Lapua .22 LR ammo. Lapua Long Range and Super Long Range ammunition comes from Finland, and is designed for the growing long-range rimfire disciplines with targets at 100-300 yards. This ammo delivers very low ES and SD numbers. Our friend F-Class John tested this ammo and confirmed it performs very well (SEE Test Video).
Capstone’s Marketing Director, Geoff Esterline, explains: “Each production lot of Lapua’s [LR and Super LR] are test-fired in 50-round groups for dispersion. The results determine whether it makes Super Long Range or Long Range packaging.”

Making your own precision handloads is a meticulous journey with many steps, many important matters to consider, and many sets of measurements to calculate. For those who pursue the perfect group, the highest score, the really long accurate shot, the rewards more than outweigh the effort. Choosing the right cases, deburring the flash holes, making the primer pockets uniform, trimming the cases, and lubricating them are all familiar – and critical – steps along the journey. And now that your brass preparation is complete, you are at last ready to start running the cases through your press and fill them with primers, powder, and bullets. The very first die the brass encounters is the sizing die. You insert the case, work the press’s lever to return the case to its correct pre-fired dimensions – and the journey continues.
There are three types of sizing dies to think about: neck, full-length, and small base. All three have specific benefits and potential drawbacks, and you should choose the type of die you use by thinking very carefully about what kind of shooting you plan to do with your handloads. No matter which type you select, most sizing dies will also punch out the old spent primer with some sort of decapper assembly that uses a hardened steel rod. Many types of sizing dies use an expander ball inside the die to make sure the neck of the case will accommodate a bullet after being sized. With some size dies, the expanders are easily removable and interchangeable, letting you get exactly the neck tension you want. When sizing cases (neck of full-length), rifle cases always need lube.
Neck-Sizing Dies Neck-sizing dies resize only the neck of the case. The benefit of sizing only the neck is that the brass is “worked” very little, reducing the amount of changes to the brss. [We recommend full-length sizing for all applications after the first couple of firings, and semi-auto brass should be full-length sized every time!] Sinclair recommends that neck-sized-only cartridges should not be used any in other rifle besides the one they were originally fired from [unless they are also FL-sized], or in any action other than a bolt-action.
Full-Length Sizing Dies
Full-length sizing dies resize the full length of the case, not just the neck. Full-length sizing helps create handloads that will function in any rifle, not just the one from which the cases were originally fired. The potential downside of full-length sizing is that it may shorten case life because it works the brass more than neck sizing. But it’s possible to “tune” today’s full-length sizing dies so they barely work the brass at all, as this article by Sinclair Reloading Tech Ron Dague shows.
Illustration Shows How a Full-Length Sizing Die Works
Another way to reap the benefits of full-length sizing is to use Redding’s full-length bushing dies, which size the full length of the case but use a system of interchangeable bushings that enable you give the case neck the bare minimum of resizing needed. To see how finely adjustable bushing dies are, and how they resize the case while fully supported, CLICK HERE for Video. The neck bushing helps you precisely control the neck tension to help increase the consistency and accuracy of your handloads.
Small Base Dies
A Small Base Die is another type of full-length sizing die, but one that is typically used when reloading for semi-automatic rifles, like the AR-15, M14, or AR-style .308 rifles. (It may also work well for bolt guns that need extra sizing on the lower section of the case.) A small base die works exactly like a full-length sizing die, only it compresses the brass just a bit more, usually about .001″ more, and may even push the case shoulder back just a hair. Small base dies give that extra bit of compression to the brass to help make sure the case will properly extract from a semi-automatic firearm. The upside is that you get handloads that should work flawlessly in your semi-automatic. The downside is case life may be shortened as compared to brass used only in one bolt-action rifle, because the brass is worked more.
Shoulder Bump Gauges
A handy tool for setting up your full-length sizing dies as close as possible to your rifle’s chamber is a shoulder bump gauge. The bump gauge lets you resize the case as little as possible, to extend case life and help your handloads fit your rifle almost like a neck-sized only die. You use deprimed cases fired in your rifle and bump gauge inserts to help you set up the die so it resizes the case only about .001″ to .004″, depending on what type of rifle you’re shooting.

NOTE: If you prefer drying your brass in an oven we recommend a temp setting no higher than 200° F. Better yet, use a dedicated case dryer that cannot possibly over-cook your cases.
Tech Tip by Craig Arnzen of Area419.com
As wet-tumbling brass has become more popular in recent years, guys have tried a LOT of ways to get their brass dry — towels, hair dryers, and even food dehydrators. (See Top Ten Brass Drying Methods). Another common method — albeit with some potential issues — is putting your wet brass in the oven to dry. Provided you monitor TEMP and TIME, this method is fast, effective, and easy (as long don’t use the wife’s favorite cooking pans — that’ll get you in trouble.)
With oven-drying, however, unexpected issues can arise, as illustrated by this worrisome story: “I put my brass in for an hour at 200° F and turned it off. Next thing I know I realize my wife has the oven pre-heating to 350° F. Is my brass ruined?”
If you search the AccurateShooter.com Shooters’ Forum, you’ll find at least three threads with stories like that (i.e. higher-than-expected oven temps when drying brass), and answers on both sides of the line. I know this, because it happened to me — I had some 6XC brass drying and the wife pre-heated the oven. Concerned about my cases, I consulted a genuine annealing expert, Andrew Rixon.
Andrew is the Director of Engineering and Manufacturing at Alpha Munitions, makers of premium-grade rifle brass. I had baked a batch of Alpha 6XC brass, which is exceptionally consistent and well-made. (This 6XC brass is currently out of production, but Alpha produces many other good 6mm cases including 6 PPC, 6mm ARC, 6mm BR, 6 Dasher, 6BRA, 6 GT, and 6mm Creedmoor).
Before Andrew would answer my question though, he gave me a little lesson on what really happens during annealing:
“Annealing is performed by heating the brass to specific temperatures. There are three phases of annealing: recovery, recrystallization, and grain growth. All of which have specific temperatures and or exposure times related to them. It is key for cartridge brass annealing processes to hit the recrystallization phase which allows for strain-free grains to grow. The growth of strain-free grains eliminate dislocations, drastically decreasing hardness and increasing ductility. For recrystallization to occur the material temperature must be within 600-1000 degrees Fahrenheit (F).”
He then got into really answering the question, and was (fortunately) definitive in his answer: “If the temps do not exceed 450 degrees F then there is nothing to worry about as it did not exceed the critical temperature for annealing to occur.” Editor: Caution — do NOT assume that the temperature marked on the oven knob is the actual temperature INSIDE the oven, particularly near the back. Some older ovens can be off as much as 75 degrees F. Be conservative!
Well, there you have it. If you’ve baked your brass, you’re probably OK. If you got it hotter than 450° F then there can start to be some changes to the metal.

Setting optimal bullet seating depth is very important for maximum accuracy. While some cartridges and barrels may deliver good accuracy with a wide range of bullet seating depths, other barrels may be more fussy, and may strongly prefer a specific seating depth, such as .006″ in the lands or .020″ off. To get this kind of precision, you need to know the exact position of the lands in your barrel. In addition, because barrel throats tend to move as the round count goes up, you should check the position of the lands regularly on a competition rifle.
Today’s Saturday Videos demonstrate a number of methods for finding Length to Lands in your rifle barrel. We start with the most common method — using the Hornady O.A.L. Gauge with a threaded modified case. With some practice, and a refined touch, this is actually very accurate. After this, we offer videos that have alternative methods, each with its pros and cons. You should find a method that works for you, that can achieve results within a couple thousandths for multiple measurements.
Finding Cartridge Length to Lands with O.A.L. Gauge
Probably the most common method to find length to lands is using a Hornady O.A.L. Gauge Tool with a comparator on a set of calipers. We regularly use this method with a custom modified case for our 6mmBR rifle. Using the technique described below, we can get results within .0015″ or so three out of four times. We do recommend taking multiple measurements. As explained below, be consistent and do NOT push the gray plastic rod too fast or with too much force.
During this measurement process, the modified case, with a bullet in its neck, is inserted in the chamber. Go slow, take your time. Here are FIVE TIPS that will help you get repeatable and reliable length-to-lands measurements with the Hornady O.A.L. Gauge:
1. Start with a clean chamber and clean barrel throat.
2. Make sure the modified case is fully screwed down and seated on the O.A.L. Gauge. It can sometimes unscrew a bit during repeated measurements.
3. Insert the modified case slowly and gently, but ensure the shoulder of the modified case is fully seated on the end of the chamber.
4. Push the gray plastic rod GENTLY. It is common for the bullet to be tilted a bit. You want to allow the bullet to self-center in the throat BEFORE you apply much pressure. Then tap a couple times and push until you feel resistance. Do NOT push too hard — that will jam the bullet in the lands.
5. Repeat the measurement at least 3 more times. If you follow our instructions, you should, typically, get a repeatable measurement, within 0.0015″ or so, 3 out of 4 times.
NOTE: We’ve seen some folks struggle to get repeatable measurements with this tool. In most cases, they were going too fast and pushing too hard on the gray rod, creating a hard jam.
Brownells — Using Hornady O.A.L. Gauge with Modified Case
This Brownells video shows how to use the modified (threaded) case for the cartridge your rifle shoots. Attach it to the O.A.L. Gauge, then insert a bullet into the case neck and slide the tool into the chamber. It takes a little practice to get consistent results. After getting the measurement in the barrel, you ascertain the length to lands using a Hornady Bullet Comparator attached to your calipers.
Making Your Own Modified Case — Threading the Case End
This helpful video from our friend Gavin Gear of UltimateReloader.com shows how to create a custom modified case to use with a Hornady O.A.L. Gauge. You need to drill out the primer pocket area, then tap and thread the bottom of the case.
Ultimate Reloader Shows 3 Ways to Find the Lands
This video shows three different ways to measure distance to lands. First Gavin Gear shows how to use a Hornady O.A.L. Gauge with Modified Case. The second methods shows how to use a bit of Loctite INSIDE the neck to secure a bullet. Be sure there is NO Loctite on the outside of the neck — you don’t want that in your chamber! You place the case with bullet into the chamber, then close bolt to seat the bullet. After waiting 5-10 minutes for the Loctite to set, you remove the cartridge gently. The third method (time-mark 16:50) is a Jam method using a bolt with the firing pin assembly and ejector removed (so there is no extra pressure on the case). Gavin notes: “The bullet ogive can be colored with a permanent marker if you want to indicate lands contact.”
About this third Jam method, ace F-Class shooter Erik Cortina posted: “My method is actually the last one that Travis showed. The one where you let the lands push bullet in. But it is neck tension dependent. I also put die wax in bullet ogive to prevent it from sticking in the lands. The method of seating bullet deeper and deeper until bolt closes is the Alex Wheeler method. As you said, there are a tons of ways to measure this.”
Finding Length to Lands the Speedy Way
Here is another method to find length to lands that can work with an unmounted barrel. This method is explained by Thomas “Speedy” Gonzales, a top gunsmith and ace benchrest shooter. Speedy drops a case with bullet seated into the chamber and then adjusts the seating depth with an inline seating die until there is no sticking or resistance felt. He can then adjust the true length to lands easily with his micrometer seating die. If you don’t have a modified case and do not want to partially disassemble your bolt to take measurement, you might want to use Speedy’s method.
Finding Length to Lands Using Bolt Movement — Primal Rights
This video shows how to remove the firing pin assembly in your bolt. This way the bolt can be used to advance a case with bullet smoothly into the chamber. Then the bullet seated in the case neck will move back to “first touch” contact position. Then extract the case slowly and measure.
The video host states: “Overall length gauges and modified cases tend to be close, but never as precise as we would like them to be. Here we describe how to measure the length to your lands in your rifle as precisely as possible, using a caliper and bullet comparator.” NOTE: The host says a store-bought Modified Case may not deliver that exact same length from case base to lands as your own fired case. That is true, but as long as the commercial Modified Case gives you repeatable results, you have a functional reference point which you can then use to test seating depths relative to that measurement.
Finding Length to Lands Using Bullet in Case With Split-Cut Neck
Here is a common method that requires no special tools. Simply take a fired (no primer), neck-sized case and split the necks down vertically with a Dremel. Done right, this will hold the bullet in place when you chamber the unloaded round. As the bullet touches the rifling it will move back. As the cartridge chambers, the bullet slides back into the case to give you length to lands. This is not super-accurate but it is probably good enough for finding the length to lands for a hunting rifle. The video maker explains: “No need to purchase gauges for this if you are willing to sacrifice one case. With a little time and patience you can get good results with this method.” Further Explanation.
How to Adjust Tension — Length and Number of Neck Cuts
Forum member Andris Silins, who uses this method, explains: “I made the neck cuts using a Dremel with a cut-off wheel. You can adjust tension two ways. First, you can make the cuts longer or shorter. Longer cuts = less tension. If you used only three cuts instead of four you would get more tension. The trick is to be gentle when you open and close the bolt. If you ram the bolt closed you may wedge the bullet into the lands. When you open the bolt it helps to keep a finger or two near by to guide the case out straight because the ejector wants to push it sideways.” READ MORE.
Finding the Lands with HK Rifleworks
This is another video that demonstrates how to disassemble the bolt so that the firing pin assembly and spring does not apply pressure on the empty case which would affect the bullet as it touches the lands. The video maker shows how to use a Brownells bolt disassembly tool to quickly take the bolt apart (3:20 time-mark). Once you have a repeatable measurement, you know exactly where is “first touch”. Then you can adjust your seating depth to be into the lands, or jumping the bullets. Many benchrest shooters like to load “into the lands”. PRS/NRL shooters and hunters will generally prefer to jump their bullets .0020″ or more.
For some applications, we prefer a non-bushing FL die over a bushing die. Shown here are three Forster full-length sizing dies, with necks honed to three different dimensions: 0.265″, 0.266″, and 0.267″.
The Honed Full-Length Sizing Die Option
There are many good options in full-length (FL) sizing dies. Most precision hand-loaders prefer FL dies with neck bushings. These let you adjust the “grip” on your bullet by using larger or smaller bushings. FL bushing dies are available from Whidden Gunworks, Forster, Redding and other makers.
Conventional, non-bushing full-length sizing dies can create ultra-accurate ammo with very low run-out. But many conventional non-bushing FL dies have an undersized neck diameter so you end up with excess neck tension, and you work the brass excessively.
There is another effective option, one that promises extremely low run-out. The honed FL die is a full-length sizing die that has the necked honed to provide a precise fit to the case-neck. When done right, honed FL dies produce extremely straight ammo — as there are no issues with bushing alignment (or bushings that are not perfectly concentric). This Editor owns honed dies from Forster, Redding, and Whidden Gunworks. They all perform extremely well, delivering match ammunition with extremely low run-out measured with a 21st Century Concentricity Gauge.
In one of the most popular articles we’ve ever published, Bugholes from Bipod, California shooter “Froggy” explained why he prefers honed dies for his tactical ammo.
Q: Do you FL size every time? Do you use custom dies?
Absolutely, I full length resize all of my brass every time I reload. And guess what? I’ve never had a feeding problem.
I do use a modified sizing die, without bushings. My FL resizing die has been custom-honed in the neck area to give .0015″ press fit on the bullet. I also put a slightly larger radius at the neck shoulder junction. I feel that this helps to seal the chamber. With this die, I get consistent neck tension every time–without bushings. Bushings are useful when you’re fishing around for a good load. But once you find the right amount of sizing for ideal neck tension, you can do this better with a customized FL die.
6.5 Guys Review Forster Honed Full-length Dies
The 6.5 Guys have reviewed honed FL sizing dies from Forster, explaining the pros and cons of this type of reloading die. They explained that, if you load a wide variety of bullets from different manufacturers, you many want to stick with a Bushing FL die. However, if you have settled on a particular bullet and found the “ideal” neck tension, then a honed die may make sense.
In this Gear Update, the 6.5 Guys discuss a service offered by Forster Products to custom hone the neck diameter of its full-length sizing dies to the customer’s specifications (to the thousandth). Whidden Gunworks has also crafted custom-honed FL dies for many customers, including this Editor.
In this video, Gavin meets with Paul Phillips, an ELR “King of Two Miles” past Champion. Paul explains the features in his .375-caliber rifle designed to shoot to one mile and beyond. Along with a big action to hold the very long cartridge, an ELR rifle needs a special high-angle optics rail to allow the needed elevation. In addition, a long-wheelbase chassis is optimal for greater stability and balance. Recoil is very significant so Paul’s rifle boasts a massive 6-port muzzle brake on the very long barrel (ELR barrels can run 34-36″). For his projectiles, Paul is running Berger’s impressive new 410gr .375 caliber Hybrid Target Bullet (6:25 time-mark).
Neck-sizing dies resize only the neck of the case. The benefit of sizing only the neck is that the brass is “worked” very little, reducing the amount of changes to the brss. [We recommend full-length sizing for all applications after the first couple of firings, and semi-auto brass should be full-length sized every time!] Sinclair recommends that neck-sized-only cartridges should not be used any in other rifle besides the one they were originally fired from [unless they are also FL-sized], or in any action other than a bolt-action.
