Do you use bushings to size your case-necks? Are you assuming that your bushings are actually round on the inside, with a hole that’s centered-up properly? Well you may be in for an unpleasant surprise, based on what our friend Jim de Kort recently discovered. Jim was concerned about the run-out on his brass. His cases went into his bushing-equipped FL die pretty straight, but came out of the die with up to .004″ run-out. “What gives?”, Jim wondered. “Could the problem be the bushings themselves?”
To answer that question, Jim decided to examine his bushings. Using an Accuracy One Wheel-drive concentricity gauge, Jim checked out some of his neck bushings. What he discovered may surprise you…
Neck Bushing Flaws Revealed
Trust no one… — Jim de Kort
Jim writes: “I measured the concentricity of my 6BR rounds today. I noticed they went into the neck-bushing equipped full-length sizing die with less than .001″ deviation but came out with .003-.004″. The culprit, it appears, was the bushing itself. Without it the cases stayed within .0005″ to .001″ deviation, so something was happening with the bushing.
One bushing had .00025″ deviation on the outside, yet almost .003″ on the inside, so it is crooked. But even when using a bushing that is within .001″ I still get .003″ runout after sizing. I repeated the same procedure for my 6×47 and got the same results. When using the bushing, concentricity suffers a lot.”
Before we bash the bushing-makers, we must acknowledge that many different things can contribute to excessive run-out and/or mis-alignment of case-necks. We don’t have all the answers here, and Jim would be the first to say that some mysteries remain. Still, these are interesting results that give all precision hand-loaders something to think about.
Jim Borden of Borden Accuracy also offers this tip: “Check the trueness of the face of the die cap. That has more to do with trueness than the bushing. Also check perpendicularity of hole in bushing to top surface. When I was making dies, the cap was made by threading and facing the threaded tenon in same setup.”
Editor’s Comment: Many people have great results with neck-bushing dies, but Jim isn’t the only fellow who has seen some very odd results. I personally employ honed, non-bushing dies for many of my chamberings. These non-bushing dies (with the necks honed for .002-.003″ neck tension) produce extremely straight ammo, with run-out consistently under .0015″.

Sierra Bullets has released load data for the 6.5 Grendel, a popular cartridge that works equally well in bolt guns and AR15-platform gas guns. Sierra published comprehensive 6.5 Grendel load data, covering 19 powders and eight (8) different bullets from 85 to 130 grains. NOTE: Hornady-brand brass (see below) was used for Sierra’s 6.5 Grendel tests, not the stronger Lapua 6.5 Grendel brass. Hand-loaders using Lapua 6.5 Grendel brass may need to adjust their loads. Also Winchester WSR primers were used. We imagine most precision hand-loaders will prefer CCI or Federal primers.
Sierra Bullets Tested for 6.5 Grendel Load Data
85gr HP (#1700)
100gr HP (#1710)
107gr HPBT (#1715)
In developing its 6.5 Grendel load data, Sierra tested a very wide selection of propellants, 19 in all. For the 85gr to 100gr varmint bullets, modern powders such as XMR 2230, Power Pro Varmint, and Ramshot TAC offered the best velocity in the 24″ test barrel. For the heavier 120gr to 130gr match bullets, Sierra tested a selection of powders. Highest velocities came with Power Pro Varmint and TAC. If you’re looking for best accuracy, consider the slower burn-rate powders such as IMR 8208 XBR and Varget — but you’ll sacrifice some speed. Overall, Sierra’s latest 6.5 Grendel load data is an excellent addition to the 6.5 Grendel knowledge base. Thanks Sierra!
Here are Sierra’s 6.5 Grendel Load Data Charts for Sierra’s 123gr HPBT, 130gr HPBT, and 130gr TMK. There are a five other tables for lighter-weight Sierra bullets.
History of the 6.5 Grendel Cartridge
The 6.5 Grendel originated as a 6mm PPC necked up to 6.5 mm. After Alexander Arms relinquished the “6.5 Grendel” Trademark, the 6.5 Grendel was standardized as an official SAAMI cartridge. It has become popular with target shooters and hunters alike because it is accurate, efficient, and offers modest recoil. Good for small to medium game, the 6.5 Grendel is available in lightweight hunting rifles, such as the Howa Mini Action Rifle. And the 6.5 Grendel is one of the most accurate cartridges suitable for modern AR-15 platform rifles.
It’s great to be able to access online load data for your cartridges. You can quickly get load data for a particular powder and bullet weight. However, there are times when we prefer to consult old-fashioned printed/bound load manuals. The primary reason is that manuals produced by bullet- and tool-makers will, for a particular cartridge, include data for powders from multiple manufacturers. Having a single source can save you time and trouble. For example, if you want to find 6.5 Creedmoor loads using H4350 (Hodgdon), Reloder 16 (Alliant), and N150 (Vihtavuori) you would have to visit three different powder-maker websites, one after another. OR you can pick up a modern load manual and find everything in one place.
There are many excellent printed load manuals on the market. We have used the Berger Manual, Sierra Manual, Nosler Manual, Lyman Manual, and Hornady Manual. We like the Berger and Sierra manuals for match rifle cartridges, and the Nosler, Lyman, and Hornady manuals for hunting loads and pistol cartridges.
The Lyman Reloading Manuals have earn praise over the years:
“Every other reloading book I’ve used favors their own bullets over every other manufacturers. With Lyman you get an honest representation of a wide variety of different… manufacturers. [Lyman has] a ton of reloading data on just about any bullet style you can imagine. I’ve tried a wide range of their recipes and everyone I’ve tried has been spot on. The overall breadth of information this book covers is impressive.” Review by RangetoReal.com.
Nosler #9 Manual Features New Cartridges
If you are looking for fairly recent cartridge/bullet/powder information, in late 2020 Nosler released the Nosler Reloading Guide #9, the latest in a respected series of Nosler load manuals.
This 800-page guide covers 101 cartridge types. New in this edition you’ll find the popular 6mm Creedmoor, 6mm XC, 6.5 PRC, and 7.62×39, along with 20 Nosler, 22 Nosler, 24 Nosler, 27 Nosler and 33 Nosler. This manual is a good resource for PRS shooters and hunters. The Nosler #9 book draws from thousands of hours in the Nosler Ballistic Lab, along with the experience of many respected experts.
The book is available for $31.99 at Midsouth or $29.95 on Amazon. Keep in mind that much of the book’s latest load data is available for free on the Nosler.com online LOAD DATA Center. But to get ALL the data, PLUS all the technical articles, you’ll need to buy the book.
Along with the Nosler #9 Manual (above), here are four other recommended Reloading Manuals:
Here Are Four General Instructional Books That Cover Reloading Procedures:
POWDER BURN RATE TABLE
Here is the most recent powder burn rate chart from Hodgdon/IMR that we could find. Click links below to access printable PDF. Note, some readers have suggested a couple powder ranking issues in the table. However, this is the latest official version from the Hodgdon website, released in October 2022.
Shown is the Redding Model 15-P Competition Piloted Inside Chamfering Tool with pilot rod that centers in the case flash hole. Also shown is a Forster 45° Rocket Tool.
There are a wide variety of reloading tools designed to cut a slight chamfer in case necks and deburr the edge of the case mouth. You don’t need to spend a lot of money for an effective tool. A basic “rocket-style” 45° chamfering tool, such as the Forster, actually does a pretty good job taking the sharp edge off case mouths, particularly if you use a little scotch-pad (or steel wool) to smooth the edge of the cut. The Forster chamfer tool, shown below, is a nicely-made product, with sharper cutting blades than you’ll find on most other 45° chamferers. It costs $24.99 at Brownells.com.
Redding sells a handy piloted chamfering tool with a 15° inside cutting angle and removable accessory handle. This Redding Model 15-P chamferer works really well, so long as you have consistent case OALs. The pilot rod (which indexes in the flash hole) is adjustable for different cartridge types (from very short to very long). This ensures the concentricity of the inside neck chamfer to the case mouth. This quality tool works with cases from .22 to .45 Caliber, and retails for $36.99.
Sinclair International offers a 28° carbide chamferer with many handy features (and sharp blades). The $28.99 Sinclair Carbide VLD Case Mouth Chamfering Tool will chamfer cases from .14 through .45 caliber. This tool features a removable 28° carbide cutter mounted in the green plastic Sinclair handle. NOTE: A hex-shaft cutter head power adapter can be purchased separately for $19.99 (Sinclair item 749002690). This can be chucked in a power screwdriver or used with dedicated power drives when doing large volumes of cases.
Many folks feel they can get smoother bullet seating by using a tool that cuts at a steeper angle. We like the 22° cutter sold by Lyman. It has a comfortable handle, and costs just $12.99 at MidsouthShooterssupply.com. The Lyman tool is an excellent value, though we’ve seen examples that needed sharpening even when new. Blade-sharpening is easily done, however.
K&M makes a depth-adjustable, inside-neck chamferer (“Controlled Depth Tapered Reaper”) with ultra-sharp cutting flutes. The latest version, which costs $59.95 at KMShooting.com, features a central pin that indexes via the flash hole to keep the cutter centered. In addition, the tool has a newly-designed handle, improved depth-stop fingers, plus a new set-screw adjustment for precise cutter depth control. We caution, even with all the depth-control features, if you are not careful, it is easy to over-cut, slicing away too much brass and basically ruining your neck. We think that most reloaders will get better results using a more conventional chamfer tool, such as the Forster or Redding 15-P.
One last thing to note — tools like the K&M and the Sinclair chamferer are often described as VLD chamferers. That is really a misnomer, as bullets with long boat-tails actually seat easily with very minimal chamfering. In reality, these high-angle chamferers may be most valuable when preparing brass for flat-base bullets and bullets with pressure rings. Using a 22° or 28° chamferer can reduce the risk of cutting a jacket when using VLD bullets though — so long as you make a smooth cut.
For this Saturday-at-the-Movies session we offer a selection of videos featuring interesting tools and products for handloaders. If you spend much time in your reloading room, these tools can save you time and help you load better ammo in less time. Today’s feature products range from sophisticated, premium tools such as 21st Century powered neck-turning lathe, to basic add-ons such as Lee Breech Lock Bushings, which are very handy if you load a variety of cartridge types.
21st Century Powered Neck-Turning Lathe
Power is activated by the red button on the end of the blue, horizontal feed handle:
Do you neck-turn hundreds of cases annually? Then you deserve this outstanding tool. The 21st Century Innovation Powered Neck-Turning Lathe may well be quite simply the best system ever created for quickly and precisely uniforming (and reducing) the neckwall thickness of cartridge brass. We have the original manual 21st Century neck-turning lathe, and can attest that it works great. With this powered system you can turn necks faster and more efficiently, with less effort. This is like going from a stick shift to an automatic transmission. The cases feed very smoothly and the results are beautiful. Note: The videos show the version as first marketed by 21st Century Shooting, which now operates as 21st Century Innovation.
The Powered Neck-Turning lathe is a modular system. Swing the bar from right to left to feed the case. The power head (with case holder) glides on stainless steel rails for smooth movement. This allows very precise feed rate. Power is supplied via a button that is built into the end of the feed handle. Push the red button to make the case spin. It’s as simple as that.
Hornady OAL Tool and Hornady Bullet Comparator
Gun Tech Steve Ostrem explains how to properly use Hornady’s Overall Length Gauge to determine length-to-land precisely. The OAL Gauge uses a “Modified Case” that threads onto the tool and holds a bullet. Push on the back of the gauge until you feel the bullet just touch the rifling. (We do this gently at first, tapping the rod a couple time to ensure the bullet is aligned correctly). Once you’ve got the length, then use the tool with a comparator on your calipers to get the length-to-lands. NOTE: We recommend taking the measurement 3-4 times in a row to get a reliable number. With a little practice your should be able to get repeatable measurements within .0015″.
Henderson Power Case Trimming/Chamfering Machine Test
F-Class John tests some of the finest reloading and shooting equipment you can buy. Recently he added the impressive Henderson Gen 3 Powered Trimmer to his inventory of tools. John is now a Henderson fan. He likes the speed, precision, and repeatability of the $779.00 Henderson machine, which trims-to-length and chamfers the case mouth all in one pass. Unlike some other trimming tools, the Henderson indexes off the overall case length NOT the shoulder. John found this worked just fine for his .284 Winchester brass, which has all been full-length sized prior to trimming.
Watch the video to see the Henderson trimmer in action. The dual, parallel horizontal support shafts provide precise alignment of the case as it moves inward toward the cutter blade. The Taper-Lock cutter provides a 14-degree inside chamfer and 30-degree outside chamfer. The trimming process is very consistent case after case, and the Henderson’s design captures brass shavings effectively.
This related video shows a comparison with the popular Giraud Powder Trimer
As noted in this comparison, John liked the precision of the Henderson trimmer and the overall design of the machine, which offers good ergonomics and very precise alignment of the cases. Cycling is smooth and positive, as you can see from the videos. The Giraud is also an excellent machine for bulk trimming/chamfering but the Henderson has some advantages.
Concentricity Checking with Accuracy One Gauge
Every serious hand-loader needs a quality concentricity gauge. The Accuracy One Concentricity Gauge boasts a smart design that delivers precise, repeatable results. We like the unit’s easy adjustability and its ability to work in a variety of configurations. The Accuracy One Gauge measures internal and external neck runout of cartridge cases as well as seated bullet runout. It can also measure the runout of the ogive, bearing surface, and boat-tail of individual bullets. And it can even measure your primer pocket runout.
Tools Galore — Affordable Tools and Accessories for Reloaders
This detailed 15-minute video from the Bolt Action Reloading YouTube Channels, features a variety of lower-cost products/tool that help with key reloading tasks. The video looks at hand priming tools, case prep tools, Lyman stepped loading blocks, powder tricklers, expander mandrels, powder trickler, long-tube funnels and more! If you are getting started in hand-loading, this is a very helpful video to watch. It covers a lot of ground, illustrating options for tool types.
This Lyman case prep tool is one of many products reviewed in this 15-minute video.
Sinclair International has created a series of instructional videos illustrating the basics of metallic cartridge reloading. The 8-Part series starts with reloading basics and provides step-by-step, how-to instructions that will help new reloaders get started. Detailed, animated illustrations show you what happens inside the chamber when shooting, and inside the dies during each step of reloading. The videos can be viewed on Sinclair International’s YouTube channel. Shown below is the first video in the series:
Each of the Sinclair videos is hosted by then Sinclair Int’l President Bill Gravatt (now with Creedmoor Sports). Bill doesn’t just show you “how”, he tells you “why”. The how-to segments cover case inspection, proper die set up, case sizing, primer installation, powder measuring, bullet seating, crimping, and even goes into the record keeping needed for the handloader. “We wanted to give shooters who haven’t reloaded a look at all the advantages of creating your own ammo and how easy it is to get started,” said Gravatt, “without telling them they had to have any certain brand or type of equipment to do the job.”
The Eight Video Topics Are:
Part 1 — Intro to Video Series
Part 2 — Intro to Reloading Safety
Part 3 — Metallic Cartridge Components
Part 4 — The Firing Sequence
Part 5 — Tools for Reloading
Part 6 — Loading Bottle-Neck Cartridges (2 videos)
Part 7 — Loading Straight Wall Cartridges
Part 8 — Reloading Series Conclusion
Reloading Tools
Shown below is Part 5 of the video series, covering the tools used for precision reloading.
We also strongly recommend the Part 4 Video to readers who are getting started in reloading. This “How Things Work” segment covers the sequence of events inside the chamber (and barrel) when the cartridge is fired. The video includes helpful graphics that show what happens to the primer, powder, cartridge, and bullet when the round is fired. The video also illustrates “headspace” and explains how this can change after firing. We think this video answers many common questions and will help reloaders understand the forces at work on their brass during the firing process.
More and more shooters are “wet-tumbling” their brass (in liquid) with reusable polishing media, rather than using dry media in a vibratory tumbler. The “wet-cleaning” method works best with a rotary tumbler fitted with a water-tight, horizontal drum to hold your brass, cleaning solution, and stainless, pin-type media. The rotary tumbler of choice has been the Thumler’s Tumbler Model B Heavy-Duty. That is a great, sturdy machine, but now you have a more affordable option.
Frankford Arsenal offers “Platinum Series” rotary tumblers designed to clean cartridge brass with liquid and stainless media. The watertight, polymer drum rides on four rollers which rotate the drum around its horizontal axis. Two filters are provided so you can quickly separate your brass and media. A built-in timer allows you to set tumbling sessions up to three hours. There is a large, 7-liter unit and a smaller, 3.3-liter tumbler. Frankford Arsenal says the big version will clean up to 1000 cases of .223 Rem brass. That’s impressive capacity.
Rotary Tumbler Sources Online
The Frankford Arsenal Platinum Series rotary tumblers are sold by major retailers including Grafs.com, Midsouth, and MidwayUSA. Shop multiple vendors to find the best current pricing.
Amazon often has very competitive pricing on the Frankford Arsenal Tumblers, both the 7-liter unit and the smaller, 3.3-liter tumbler.
How to Wet-Clean Your Brass in a Rotary Tumbler On our main Accurateshooter.com website, you’ll find a comprehensive review of the STM system for cleaning cartridge brass with stainless media. To clean brass with stainless media, start with five pounds of small stainless pins sold by StainlessTumblingMedia.com. Place these along with a gallon of water, a little liquid cleaner, and two pounds of cartridge brass in a rotary tumbler, and run the machine for one to four hours. After cleaning be sure to inspect all your primer holes. CLICK HERE for Brass Cleaning System Review.
Forum Member Tests STM System
Our reviewer, Forum member Jason Koplin, purchased the STM media and a new Thumler’s Tumbler. He then tested the STM cleaning procedure on his own brass, including some extremely dirty and tarnished “range pick-up” brass. Jason was thoroughly impressed with how well the STM process worked — as you can see from the “before and after” photos below. Brass which looked like it was ready for the scrap heap was restored to “like-new” appearance. The process works equally well on both rifle brass and pistol brass. Jason observed that one surprise benefit of the STM cleaning procedure is a big reduction in noise. Jason said the water-filled rotary tumbler was much quieter than his vibratory tumblers. One tip though — you should always inspect every cartridge carefully after wet-tumbling with stainless media. With large-flash-hole brass it is possible to have a pin stuck in a flash hole. This is rare, but it CAN happen.
Forum member F-Class John is an avid F-Class competitor and expert handloader. This week he won the NRA F-0pen Mid-Range National Championship. John reviews reloading hardware and shooting-related products for his popular F-Class John YouTube Channel, which now boasts 540+ videos. John also does product testing for AccurateShooter.com and his new FClassJohn.com website. On his YouTube channel, John has reviewed many of the latest and greatest reloading tools and accessories. Below are three interesting F-Class John tool and reloading product reviews.
If you like these informative videos, consider joining F-Class John’s Patreon Channel for live video meetings, more in-depth videos, and detailed explanations.
Here are three of John’s most interesting gear review videos for products that can benefit all serious handloaders.
21st Century Hydro Press and Standard Arbor Press
John notes: “You can’t really talk about precision reloading without taking about inline dies and arbor presses. For my money there’s nothing better than the lineup from 21st Century Shooting. They offer the Hydro Seater which is hands-down the best manual seater out there as well as their standard arbor press which is great for taking on the road to push back bullets as needed.”
Henderson and Giraud Power Trimmer Comparison Review
In this video John reviews two high-quality powered case trimmers that help handloaders rapidly process large volumes of brass. He says these are “arguably the two best trimmers on the market” and are “both worth the money if you do a lot of trimmming”. The Giraud Power Trimmer is rugged and popular with high-power shooters. The advanced, red Henderson Precision Gen 3 Trimmer offers some advantages for precision trimming and John likes the Henderson layout and ergonomics.
Concentricity Checking with Accuracy One Gauge
Every serious hand-loader needs a quality concentricity gauge. The Accuracy One Concentricity Gauge boasts a smart design that delivers precise, repeatable results. We like the unit’s easy adjustability and its ability to work in a variety of configurations. The Accuracy One Gauge measures internal and external neck runout of cartridge cases as well as seated bullet runout. It can also measure the runout of the ogive, bearing surface, and boat-tail of individual bullets. And it can even measure your primer pocket runout.
Whidden Gunworks makes great sizing and seating dies. The Whidden full-length sizing die with neck bushing is very popular because it allows you to “tune” the neck tension by using different bushings, with larger or smaller inside diameters. In this video, John Whidden explains how to choose a the right bushing size for use with your neck-sizing and full-length sizing bushing dies.
For most applications, John suggest starting with the caliper-measured outside diameter of a loaded cartridge (with your choice of bullet), and then SUBTRACT about three thousandths. For example, if your loaded round mics at .333, then you would want to start with a 0.330 neck bushing. John notes, however, that you may want to experiment with bushings, going down a thousandth and up a thousandth. With thin In addition, as your brass ages and the necks harden, you may want to change your bushing size.
Quick Tip: Try Flipping Your Bushings
You may also want to experiment with “flipping” your neck bushings to alternate the side that first contacts the neck of the case. (One side of the bushing is usually marked with the size, while the other side is unmarked.) So try “number side up” as well as “number side down”.
Some folks believe that one side of the bushing may allow a smoother entry, and that this can enhance concentricity. Other people think they can get very slightly more or less neck tension depending on how the bushing is oriented. This is a subtle effect, but it costs nothing to experiment.
If one bushing orientation proves better you can mark the “up” side with nail polish so that you can always orient the bushing optimally. NOTE: We have confirmed that some bushings are actually made with a slight taper. In addition, bushings may get distorted slightly when the brand name and size is stamped. Therefore there IS a reason to try both orientations.
