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″.

CCI is now producing Catalyst lead-free primers and Catalyst-primed CCI and Speer ammunition at the CCI factory in Lewiston, Idaho. The proprietary Catalyst lead-free primer was first developed in 2016 by Federal Ammunition, a CCI/Speer partner company. The advanced lead-free Catalyst primers have been used in CCI- and Speer-brand pistol ammo, and are featured in Federal’s Syntech Range ammo and American Eagle lead-free ammo. Eventually, CCI may eventually offer lead-free primers for the reloading market.
Writing for the MagLife Blog, Kat Ainsworth described Catalyst lead-free primers: “Many manufacturers use lead styphnate mixtures in the production of primers, but Federal Ammunition states the proprietary design utilized in the Catalyst is not only lead-free but outperforms those other methods. The company also says the Catalyst primers are safer to manufacture and provide a host of benefits over lead designs. For example, the Catalyst primers deliver greater compatibility with modern powders, produce less pressure from the gases generated during live fire, and don’t cause degradation in the powder they touch.
The company says these primers are extremely clean-burning which helps them perform more uniform and complete propellant combustion. Even better, the Catalyst has minimal velocity variation[.] These primers are also non-hydrophilic, meaning they don’t attract water molecules like DDNP-based mixes that are found in other brands[.]”
Catalyst Primers Promise Best-in-Class Performance
“We are extremely proud of this new production capability which continues the rollout of an incredible primer technology” said Federal/CCI/Speer President Jason Vanderbrink. “This product has proven to be the best in its class after nearly seven years of continuous production. Its consistent performance has been tested over hundreds of millions of rounds. Most notably, the product is featured in Federal’s innovative Syntech Range ammo and American Eagle Lead-Free.”
The extremely clean-burning Catalyst primer creates more uniform and complete propellant combustion, yielding minimal velocity variation and consistent bullet launch for improved accuracy. It is also non-hydrophilic, so it does not attract water molecules like DDNP-based mixes found in most lead-free primers, resulting in better reliability.
“Catalyst lead-free priming technology provides the cleanest, most consistent ignition possible. We are excited that our Lewiston plant is now set up to run Catalyst priming in our target pistol products”, said Speer and CCI’s Director of Factory Operations Mike Overberg. “The Anoka facility has proven this to be the best lead-free priming technology available. Our staff here has done a fantastic job of working across factories to extend this product into Speer and CCI Blazer ammunition products made in Lewiston, Idaho.”

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:

In the wintertime, it’s common to encounter problems with static electricity when throwing your powder charges. The static can cause powder kernels to cling to the surface of reloading components, and can cause powder clumping. Clumped or sticky powder may make your measure bind or grab in the middle of the cycle, which can throw off your charge weight. Here are a couple simple ways you can minimize the effects of static electricity and improve the consistency of your powder measuring.
Ground Your Powder Measure — If you’re throwing powder charges in the fall or winter and have problems with bridging or sticking powder, use a ground wire. Bullet-smith Victor Johnson (Johnson Precision Bullets) tells us: “I have a 25-foot piece of real small wire with alligator clips on each end. It’s that long so I can run it down the hall to a water pipe. Use the wire tie from a bread bag to hold it in a small roll to put in the range box. When using it at the range use a 6″ nail from the co-op or Lowe’s / Home Depot and just push it into the ground.”
Use Bounce Dryer Sheets — A quick pass with the thin sheets used in dryers will eliminate “static cling” on your plastic reloading parts like powder throwers, powder funnels, and reloading press guides. Thanks to Doc76251 for this tip.
Reduce Electronic Scales’ Drift with Anti-Static Spray
Very sadly, GS Arizona, the creator of the Rifleman’s Journal website, passed away unexpectedly in June of 2022. Here is one of the many great tips he provided to handloaders through that website.
Apparently reducing static charges on and around electronic scales can reduce their propensity to drift, lessening the problem of “wandering zero”. Just how and why static charges interfere with scale performance is unclear, but many shooters have noticed that static electricity can cause electronic scales to behave strangely. So how do you reduce static charges around your digital balance? GS Arizona has found a very simple solution — an anti-static aerosol spray — that, by all indications, actually works. When this “spray-can solution” was suggested by a fellow shooter, GS was skeptical. However, he tried the stuff and he says that it really does help the scale maintain zero over time, with much less observed drift.
GS explains that the use of “Static Guard” spray helped mitigate the problem of a drifting zero on his Ohaus electronic scale: “My electronic scale… suffers from drifting zero (as they all seem to). I’ve read dozens of forum posts about drift and how to minimize its occurrence, so I know this problem isn’t limited to my scale or my workshop. Sometime last year, John Lowther mentioned the use of anti-static spray as a solution to the drift problem. John stated that the spray had virtually eliminated drift for him.”
GS found that the Static Guard actually worked: “The spray works great, just as John said it would. I spray all surfaces that I touch with my hands and arms as well as the pan (top and bottom), the metal tray on which the pan rests and the table under the scale. In six months or so of using the spray I’ve re-applied it about two or three times; it certainly isn’t something that you need to do each time you sit down to load. Before using the spray, it was not uncommon for me to re-zero the scale 10 times in the course of loading 72 rounds; now it might need it once during a session.”

All of us who have been in reloading and shooting for any period of time have read how sectional density has been regarded as a bullet’s ability to penetrate. Back before high velocity came along and modern bullet design, the easiest way to get more “power” and penetration was by increasing the diameter and mass. After all, a bowling ball will hurt more than a golf ball, right?
Let’s take a closer look at sectional density.
The formula for calculating sectional density is pretty simple and straight forward. Take the bullet weight and divide by 7000. This number is then divided by the bullet diameter squared. Two bullets of equal weight and the same diameter will have equal sectional sectional density. No regard is given to the bullet construction. This is where the fly hits the soup in considering sectional density as far as penetration is concerned.
Section Density Formula: (Bullet Weight divided by 7000) divided by Bullet Diameter squared.
Bullet construction is the biggest factor in how it is able to penetrate. The best example I can think of here is to look at the Sierra .224 55 Gr. FMJBT GameKing #1355 compared to the 55 Gr. BlitzKing #1455. Both are .224 and weigh 55 grs. Both have a sectional density of .157. But there is a huge difference in their construction. The FMJ has a thick jacket and is designed to penetrate. The BlitzKing is designed for fast and rapid expansion with little concern for how deep they will penetrate.
The next time you’re choosing a bullet, look at the construction and less at the sectional density number. It’s all about the construction anyway. If you have any questions or would like to discuss sectional density or bullet penetration further, please give us a call at 800-223-8799 or shoot us an email at sierra@sierrabullets.com.

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.

When shooting targets, the closer to the center the better the result. But this is not necessarily true when it comes to using jags and patches. There are some good reasons to try spiking your patches away from the center. This Creedmoor Sports Tech Tip explains why you may want to spike (puncture) your patch away from the center. CLICK HERE to order patches and Swab-Its cleaning bore tips from Creedmoor Sports.
You begin to push your first patch down the barrel and you notice it is extremely tight and then it jams! How can this be? A commonly overlooked solution to remedy the frustrating occurrences of overly tight or jammed patches is what we like to call “Side-Spiking”. Side-Spiking is super simple and works!
“Side-Spiking”, as the words suggest, refers to moving your patch spiking position from the center of the patch towards the corner of a square patch or the edge of a round patch.
Moving From Center-Spiking To Side-Spiking
The closer toward the edge of the patch you spike your jag, the looser the patch will be when pushed down the bore.
Important: Be careful to not go to the very edge of the patch. Leave enough patch material to fully cover the first set of rings on your jag as this insures your jag is properly centered in the bore and that no contact with the rifling will occur.
Proper Side-Spiking Location Creedmoor Sports recommends side spiking all wet patches. This allows for a looser patch in the bore which removes gross powder fouling and leaves more cleaning solution behind to start working on the remaining fouling.
When a tighter patch is needed, simply move your spike closer toward the center of the patch. The closer to the center of the patch you get, the tighter the patch will become in the bore. The objective is to have a snug-fitting patch that allows you to smoothly push your rod down the bore. Remember you do not need to end up in the center of the patch!

With inflation, the increased cost of .223 Rem centerfire ammo has driven more folks to shooting .22 LR rimfire ammo, both for fun and practice. Thankfully, handy conversion kits will let you shoot .22 LR ammo from your existing .223/5.56 AR-15 platform rifle. This allows low-cost training with no change in rifle balance, ergonomics, and/or optics.
The CMMG Bravo .22 LR Conversion Kit provides a replacement bolt/bolt carrier along with three 25-round magazines with special .22 LR-fitted followers and ammo slots. This allows you to shoot rimfire ammo from any AR-15 chambered for the .223 Rem (5.56×45). The CMMG Bravo has an integrated extension that fits into your current chamber. The rimfire bullet passes through this extension and then enters the barrel. This conversion kit is now on sale at Brownells for $179.99 with three 25-rd mags.
The CMMG Bravo conversion Kit comes with blowback-operated .22 LR bolt carrier, rubber protector for bolt carrier tip, and three 25-round polymer magazines. To use, simply replace the rifle’s .223 Rem bolt and carrier with the Bravo .22 LR conversion unit and load up the included magazine(s) with rimfire ammo.
To use the CMMG Kit, simply remove the centerfire bolt/bolt carrier, and replace it with the CMMG silver colored bolt shown above. CMMG states: “For best performance use a round-style hammer as notched hammers can cause function issues.” Testers have stated that high-velocity .22 LR ammo works best, and CMMG notes that “36gr plated-nose bullets have proven to be the best choice for function.” The copper-plated bullets help reduce fouling.
Ultimate Reloader Tests CMMG .22 LR Conversion Kit
Our friend Gavin Gear of UltimateReloader.com recently tested the CMMG .22 LR AR Conversion Kit. He observed that installation was very straight-forward and the CMMG magazines worked well. He and fellow tester Travis Fox shot the unit both slow-fire and rapid-fire successfully.
Gavin and Travis found the CMMG Kit easy to install and fun to use. With an AR that can shoot both .223 Rem and .22 LR, it’s like having “two guns in one”. Travis was impressed with the ease of use: “It is so simple to change over to the CMMG .22 LR AR kit! It took me about 68 seconds the very first time I tried. Each time after that it took me about 40 seconds — it’s that simple. It takes longer to fully load one of the mags than it does to switch over from .223/5.56 to .22 LR and back.”
The AR shot very well with the higher-velocity ammo types. 100% functioning was achieved with both 40gr Federal Game Shok ammo and American Eagle High Velocity 38gr Copper-plated HP ammo. NOTE: CMMG does recommend high-velocity Copper-plated rimfire ammunition.
Maintenance Tip — After converting back to your centerfire .223 Rem (5.56), Travis says “make sure to clean the gas tube and components as .22 LR tends to run dirty”. READ Full Test on UltimateReloader.com.
CMMG Bravo Conversion Kit Gets Thumbs Up from Gavin and Travis
“Does this conversion kit get the Ultimate Reloader stamp of approval? Absolutely! In these times of ammunition/component scarcity this gives options to shooters. Finding bulk .22 LR can sometimes be easier than 223/5.56. This kit gives that option at a great price. Any chance to keep skills up and familiarize new shooters to a platform is a good thing. Basically two rifles for a lot less than another rifle.”
How to Install CMMG Bravo .22 LR Conversion Kit
The Brownells video below shows the installation process step-by-step:
In this instructional video, a Brownells gunsmith demonstrates (step by step) how to install, disassemble, clean, lubricate, and reassemble the CMMG AR-15 .22 LR Conversion Kits. Clear the rifle and make safe before you start the conversion. Separate the upper and lower, remove the standard bolt carrier group. You then install the conversion bolt and connect the upper and lower as normal.
Details of CMMG .22 LR Conversion Kit
“For years I’ve had a CMMG conversion kit. It’s a drop-in system that’s … very reliable and it’s accurate. The [CMMG conversion] has lower recoil [and is] great for training. Even though ammo prices have gone through the roof, .22 LR is still cheaper to shoot than anything else.” — SootchGear

We have used NO-LEAD Cleaner in rimfire benchrest rifles similar to this modified Suhl 150-1. It helped restore accuracy with minimal brushing.
Made by the same smart folks that created Wipe-Out™, and Carb-Out™, NO-LEAD Brushless Lead Remover™ really works. Honest. If you are an active rimfire shooter, or if you shoot cast lead-alloy bullets in centerfire rifles and pistols, you should try this product. We now use NO-LEAD in our rimfire benchrest rifles, and in some centerfire guns that receive a steady diet of soft-alloy cast bullets (90%+ lead). (With rimfire guns, you don’t need to use NO-LEAD very often — maybe every 300-400 rounds unless you have a real fouler of a barrel.)
If you’ve got stubborn lead fouling in a rimfire barrel, or on a pistol’s muzzle brake/compensator, you should definitely give this stuff a try. We don’t know how but it does soften lead deposits. The manufacturer says you don’t need brushes, but we found that a bit of brushing (after NO-LEAD application) can help remove more serious lead build-up.
Yes we were surprised to find a lead remover that really works. We tried a half-dozen other lead “cleaners” that promised to dissolve lead and most of them, we discovered, are nearly useless. There’s a reason for that, as the lead alloys used in bullets don’t react to typical petrochemical-based solvents. It took the Wipe-Out chemists over five years to perfect this water-based solution that really does dissolve lead.
NO-LEAD Cleaning Procedure — Read Carefully NO-LEAD Lead Remover is a clear, red gel that is easy to apply. Just swab it in your bore (or on muzzle brakes) with wet patches or bore mop and let it sit for a few minutes. (The manufacturer says you can leave the NO-LEAD for up to 20 minutes, but that long of a dwell time does not seem necessary with our rimfire barrels.) When it contacts lead it will start to foam and you’ll see that the NO-LEAD solvent turns a pastel pink when it dissolves lead. The pink comes from the formation of lead oxide. After the recommended dwell time, simply patch out the dissolved lead deposits (you can also use a nylon brush for stubborn lead build-up).
NOTE: After cleaning, it is very important that you get all the NO-LEAD out of your barrel, and neutralize it. We recommend following the application of NO-Lead with Wipe-out or Patch-Out to neutralize the NO-LEAD, clear the bore, and remove residual carbon and copper fouling. If you don’t have Wipe-Out or Patch-out, flush the barrel thoroughly with Rubbing Alcohol or even a solution of Dawn dish detergent — then re-oil the bore.
Be Sure to Neutralize NO-LEAD After Use
Remember that N0-LEAD is a strong, slightly acidic chemical that needs to be neutralized after use. If you leave it on a nice, blued barrel for too long, it can harm the bluing. NO-LEAD will remove all the surface oils from the barrel bore. For this reason it is recommended that you neutralize NO-LEAD with Wipe-Out, or Patch-Out, which both contain effective corrosion inhibitors. If you don’t have those products, once you’ve flushed the NO-LEAD with something like rubbing alcohol, then follow with a gun oil. Caution: A petroleum-based gun oil will NOT, by itself, neutralize NO-LEAD. You need to neutralize first, then apply the corrosion inhibitor (or do it all in one step with Wipe-Out or Patch-Out).
Where to Buy NO-LEAD Lead Remover
NO-LEAD Lead Remover costs $18.55 for an 8 oz. squeeze bottle with a flip-top spout. This product is sold directly by Sharp Shoot-R Precision Products through Sharpshootr.com, or you can purchase NO-LEAD through many other online vendors. For more information, send an email via the Sharp Shoot-R Contact Form or or contact SharpShoot-R at (785) 883-4444. You can ask for Terry Paul, Sharp Shoot-R’s owner and the master chemist who developed the NO-LEAD formula.
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.

Nosler #9 Manual Features New Cartridges
Apparently reducing static charges on and around electronic scales can reduce their propensity to drift, lessening the problem of “wandering zero”. Just how and why static charges interfere with scale performance is unclear, but many shooters have noticed that static electricity can cause electronic scales to behave strangely. So how do you reduce static charges around your digital balance? GS Arizona has found a very simple solution — an anti-static aerosol spray — that, by all indications, actually works. When this “spray-can solution” was suggested by a fellow shooter, GS was skeptical. However, he tried the stuff and he says that it really does help the scale maintain zero over time, with much less observed drift.
