In this video, Larry Vickers of Vickers Tactical tours a Sellier & Bellot ammunition plant in the Czech Republic. This video shows details of primer production as well as bullet-making, brass-making, and production-line cartridge manufacturing.
Remington Ammunition Plant Re-Opened by Vista Outdoors
This video shows ammo production at the re-opened Remington ammunition plant in Lonoke, Arkansas. “This is one of the largest ammunition manufacturing plants in the world” said Mark Keefe, NRA Publications editorial director. “It was set up in 1969 by DuPont, who owned Remington at the time. They do it all here. Cases, bullets, centerfire rifle, centerfire pistol, rimfire and shotshell.” It’s great to see this plant back in production after Remington Ammunition filed for bankruptcy in 2020 and the assets of the Remington conglomerate were auctioned off. Ultimately, Vista Outdoor, owner of Federal, CCI and Speer, purchased the assets of Remington Ammunition and got the Lonoke plant running again, better than ever.

What’s a “Wallet Group”? It’s a singularly spectacular proof target that entitles its bearer to bragging rights. The wallet group may or may not have been shot in competition, and, by definition, it may not be repeatable. But it exists as incontrovertible proof that, at least once, the stars aligned, and the wind gods smiled on the shooter.
Five Shots in 0.178 MOA at 1000 Yards
A few years ago, Forum member and F-Class shooter Gary Wood was testing his 6.5-284 rifle at the 1000-yard range in Coalinga, California, getting ready for an upcoming long range match. In practice, Gary nailed a witnessed 1.859″ five-shot group, with four of the five shots well under an inch. Use this as proof to win those club-house arguments about whether it is possible to shoot “in the ones” at 1000 yards. Gary’s group worked out to 0.178 MOA!
Gary reports: “I was load testing with 5-shot groups. Each group was shot on a new F-Class center and pulled by Ret. Master Chief Jerry Pullens and spotted by an other long-range shooter. The second 5-shot load group looked really small … by our reckoning four out of five shots measured under an inch. I was amazed. What’s more, when I shot the group, the 4th shot blew the spindle out of the 3rd shot. My spotter saw that in his scope and Jerry Pullens told me about it afterwards”.
As measured with the OnTarget Software, using a scan of the target, Gary plotted the group size at 1.859″ total for five shots, or 0.178 MOA. Gary noted: “I had everyone sign the target which I saved and photographed.” Yes, Gary, this may be the wallet group to end all wallet groups. You should have that target framed.
Gary’s Load and 6.5-284 Rifle Specs
Gary was running a stout load of Hodgdon H4350 and CCI BR-2 primers, pushing moly-coated 142gr Sierra MKs, in Lapua 6.5-284 brass. The rifle features an F-Class, single-shot Surgeon action with a Bartlein 5R barrel chambered with a no-turn neck. Gary says “The barrel only has 70 rounds through it… yep, I think it will shoot.” Gary did all of the gunsmithing and barrel work himself.
Did Gary have any special reloading tricks? Apparently not: “Other than weighing the cases and the powder very carefully, there really were no magical reloading secrets used. The Sierra 142s were moly-coated straight from the box of 500, but they were not weighed or checked for bearing surface. The powder was dropped with a RCBS ChargeMaster then checked with an Acculab scale (to under a tenth). The Lapua cases were not neck-turned, but I did weight-sort them. The five cases for the small group weighed: 195.05, 195.03, 195.03, 195.03, 195.01.”
Before you load that new cartridge brass for the first time, run an expander mandrel down the case necks. This will iron out dents and provide more uniform neck tension. Chose a mandrel diameter that provides appropriate neck tension.
Lapua brass is so good that you’ll be tempted to just load and shoot, if you have a “no-turn” chamber. However, some minimal case prep will ensure more uniform neck tension. Keeping your neck tension very uniform allows more consistent bullet seating. That, in turn, usually yields better accuracy, and lower Extreme Spread and Standard Deviation (ES/SD). Lapua brass, particularly 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win comes from the factory with tighter-than-optimal necks.
Before you seat bullets, at a minimum, you should inside chamfer the case mouths, after running an expander mandrel down the necks. The expander mandrels from both Sinclair Int’l (Brownells, $14.99 stainless, $24.99 Titanium Nitride coated) and K&M will both leave the necks with enough neck tension (more than .001″) so you can then seat bullets without another operation. We suggest putting a bit of lube on the mandrel before running it down the necks — but remove any lube that gets inside the necks before seating bullets. If you do a lot of loading you may benefit from a Titanium Nitride-coated mandrel.
Both Sinclair and K&M Tools make a die body specifically to hold expander mandrels. The $49.99 Sinclair version fits caliber-specific expander mandrels which measure approximately .001″ less than bullet diameter for each caliber. This is an updated “Gen II” design that completely captures the mandrel within the die so the mandrel cannot pull out. It also has an O-ring in the die cap that allows the mandrel to self-center within the case neck. Brownells offers two sizes of Sinclair die bodies for expander mandrels: .17 -.338 caliber (#749011715 $49.99); and .357 – .50 caliber (#749008843, $49.99). All Generation II dies are machined from stainless steel and the standard diameter 7/8-14 dies include the Sinclair Stainless Steel Split Lock Ring.
Once you run the expander mandrel down the necks of Lapua brass, after you account for brass spring-back, you’ll have about .002″ neck tension*. This will make the process of seating bullets go much more smoothly, and you will also iron out any dents in the case mouths. Once the case mouths are all expanded, and uniformly round, then do your inside neck chamfering/deburring. The same expander mandrels can be used to “neck-up” smaller diameter brass, or prepare brass for neck-turning.
Forum member Mike Crawford adds: “These expanders can also reduce runout from offset seating. Prior to bullet seating, expand the sized necks to force thickness variance outward. With the Sinclair system, the necks will springback fine, and will not be pulled out of center. This leaves plenty of tension, and bullets seated more centered. I do this, even with turned necks, to get improved seating.”
Mandrels vs. Expander Balls on Decapping Rods
If you haven’t acquired an appropriate expander mandrel for your brass, but you DO have a full-length sizing die with an expander ball, this will also function to “iron out” the necks and reduce tension. However, using a die with an expander ball will work the necks more — since you first size them down, then the ball expands them up again. Typically (but not always), run-out is worse when using an expander ball vs. an expander mandrel.
* This .002″ tension is what we have observed with Lapua 6mmBR, 6.5×47, 6.5 Creedmoor, and .308 Win brass. This might vary with much smaller or larger cases, and of course a different brand of brass might yield different results. If you get too little tension with your current mandrel, you can get a smaller-diameter mandrel from 21st Century Innovation, with stainless, Black Nitride, or Titanium nitride versions. The Nitride models have less friction.
Many shooters these days clean their cartridge brass ultrasonically, or wet-tumble their cases with stainless media (above). Both methods get brass clean and shiny, inside and out. However, when those wet-cleaning processes are completed, you’re left with a pile of soaking wet brass. How do you dry your brass quickly and efficiently, without unsightly water spots? Read on for some great answers…
In our Shooters’ Forum, Member Terry asked: “How do you dry your brass after Ultrasonic cleaning?” In a Reloading Forum Thread, many smart suggestions were posted. A dozen fellow members outlined a variety of effective case-drying procedures, which work equally well for both wet-tumbled brass and ultrasonically-cleaned cases. Here are the Top 10 brass-drying suggestions from our Forum members.
TOP TEN Ways to Dry Cartridge Brass After Wet Cleaning
1. Food Dehydrator — Shake the brass in towel to get the bulk of water off. Next leave in the food dehydrator for 45 minutes or until there are no signs of moisture inside the cases. — Lawrence97
2. Lyman 5-Level Case Dryer — Rinse off cleaning solution(s), then load brass by type into racks in Lyman Cyclone Case Dryer. This is easier to load/unload than food dehydrators and holds more cases.
3. Hot Water + Compressed Air — Rinse all your cases as a batch using scalding hot water from the kitchen sink. Hot water evaporates off of brass very very quickly. Then hit them with compressed air. Takes 10 minutes. Simple. — SG4247
4. Oven Dry in Pre-Heated Oven — After pre-heating to 200° or so, turn off oven and put brass inside on a tray. Most important! Tell your wife what you are doing so she doesn’t crank it up to 425 to heat pizza! — MClark
NOTE: Many other members suggested oven drying at 150-200°. We recommend turning OFF the oven so you don’t cook your brass if you forget to remove the cases.
5. Towel Dry then Warm with Heat Gun — Roll brass in a towel until no more water shakes out. Lay out on cardboard box top and blow off with Harbor Freight heat gun. $9.99 on coupon. Two minutes of heated air and about half hour of wait and they are good to go. This is with primers removed. — Shaggy357
6. Compressed Air, then Sun Dry Outside – I rinse the brass, then blow them out with compressed air. Then, dependent on the time of year, lay them on a towel in the sun. — HogPatrol
7. Dishwasher on Dry Cycle – In the winter, I drop my wet brass cases neck-down on the rack pegs in the dishwasher, then turn on the dry cycle. In the summer…well, I’m in Texas. They go to the porch for a bit. — Toolbreaker
8. Alcohol Rinse then Air or Oven Dry — Rinse in 90% Isopropyl alcohol and either let air dry or stick in 175° oven for half an hour. Alternatively, use a dehydrator. — Zipollini
9. Slow Air-Dry in Loading Blocks — I have a reloading block with holes drilled in it. I simply load the block up and let it air-dry in the cupboard for a couple of days. — JCS
10. Wipe with Towel Then Anneal Normally — This thread is stirring my OCD side. Seems complicated for just drying — my brass dries just fine when I anneal it. This entire process can’t take an hour per batch. When finished, the brass is cleaned, annealed, and ready to size. — CHLuke
Deprime, then tumble brass with stainless media, water, Lemishine, and dish detergent.
Shake them easily in a strainer to knock out most media then grab 4-5 pieces, shake them over the bucket for the last of the media then inside a towel.
Finally blow out the primer pockets and wipe with a towel, load in the Annealeez.
Here is a clever DIY tool we learned about from Frank Shuster, a Forum member, who, sadly, passed away in 2015. Frank was a very knowledgeable shooter who was always willing to help others. Here is one of Frank’s smart inventions. He devised a way to measure the length of a rifle’s chamber using a fired cartridge case. Frank’s system works by cutting a “collar” from part of the case neck. This then slips over a bullet seated in a case loaded without powder or primer. As you chamber the dummy round, the collar will move back to indicate the full length of the chamber. (Make sure the bullet is seated well off the lands so the dummy round can chamber fully.)
The pictured gauge can be home made (for free) with components you already have on hand. Frank explained: “I used a Dremel cut-off wheel to cut the front half of the case neck off. A jewelers needle file to de-burr both rough-cut edges. The cut-off surface does not need to be perfectly square, because you are using the original straight mouth to make contact at the front of the chamber. Seat any old bullet to the approximate normal seating length. Next apply a tiny drop of oil on the ogive of the bullet, and slide the ‘collar’ over the bullet. Then chamber the dummy round and close the bolt. Extract the round slowly and carefully and take the measurement with calipers (see top photo).”
Frank’s DIY chamber length gauge works well. In a related Shooters’ Forum thread, Frank posted: “I’ve compared length dimensions doing it this way and with the chamber length shown on my chambering reamer drawings, and the Sinclair gauge, and they are all within .001″ or so.”
Commercial Chamber Length Gauges May Not Work with Custom Chambers
Frank did use Sinclair chamber-length gauges for some applications. These bullet-shaped gauges slip into a cartridge, but “it’s inconvenient to order that little gauge only… without spending $6 shipping for a $7 item.” Moreover, the Sinclair gauges may not fit a custom chamber with a tighter neck dimension because the diameter of the ring at the end is too large.
As an alternative to commercial gauges, the collar-type, homemade gauge will function properly in a custom chamber. The homemade gauge will work with smaller-than-standard chamber neck dimensions, as long as you use a piece of appropriately-turned fired brass that fits your chamber.
In April 2020, the National Rifle Association (NRA) launched NRAWomen.com, a website dedicated to the fastest-growing group of firearm owners — America’s women. This website serves the increasing number of female gun owners, huntresses, and competitive shooters. Female involvement in firearms is growing significantly. Consider these numbers: Statistica estimates that 19% of women in the USA owned firearms in 2020, while 23% of women surveyed in a 2011 Gallup Poll stated they owned a gun.
Jessie Harrison is one of the greatest female pistol shooters on the planet.

1. Flying with Firearms — What You Need to Know
We recommend that any gun owner, female OR male, should definitely read this article. It is one of the better discussions on the web of airline travel with firearms, covering international travel as well as domestic flights. The article notes that you should obtain U.S. Customs Form 4457 before flying overseas with a firearm.
“Flying with a gun is actually a lot easier than you’d probably expect. You need a couple of specific gear items, and you need to know the proper procedure, but it’s a relatively simple process. I’ve flown with long guns and handguns dozens of times around the country and around the world. The process is generally the same, but with some additional steps and maybe additional hassle depending on the airport [and personnel.]” READ FULL ARTICLE on NRAWomen.com.

The second article features a great video showing how to assemble a modular safe in under 30 minutes. This article also explains the benefits of modular gunsafes — primarily easier transport and installation.
“Modular safes have been around for a few years now and are becoming more popular. Here’s why: The safe comes delivered to you in panels, so you can bring them into your home one at a time and put it together anywhere you like. This makes it easy to carry up and down stairs, onto elevators or anywhere! Security — Is it as secure as one that comes pre-assembled? The answer is, absolutely.” READ FULL ARTICLE on NRAWomen.com.
3. Rimfire .22 LR Handguns for Self-Defense
This article looks at a wide variety of .22 LR pistols and revolvers. The author discusses the pros and cons of a rimfire defense gun, concluding that while the stopping power is limited, having some protection is better than going unarmed.
“Over the last few months we’ve seen the launch of new handguns chambered for .22 LR that sport the same looks and features as center-fire handguns designed for daily concealed carry. The models I’ve had a chance to work with so far include the compact Taurus TX22 semi-automatic pistol, the pocket-size Ruger Lite Rack LCP II, Kel-Tec’s P17 semi-automatic and the Taurus 942 8-shot snubnose revolver.” READ FULL ARTICLE on NRAWomen.com.

We’ve tried this product and it definitely helps keep work surfaces and floors clean. No more messes on the bench or spray from solvents. Purchasers do like this product — it has 78% five-star reviews on Amazon.
One owner explains: “This box straps over the muzzle end of a barrel and keeps the mess completely contained. Excess cleaning solvents collect in the bottom. Patches fall off the jag and are captured as well when the cleaning rod is withdrawn. It also completely contains the splatter burst when a bore brush exits the muzzle of whatever firearm is being cleaned.” (D.J. Bradley)
Here are actual user reviews from verified customers:
“It’s been a long time since I bought something that is just WOW brilliant but this patch catcher is just that. It is so simple, so neat, so clean and so effective. It fits perfectly on all my rifle barrels and catches patches, brush spray and most importantly most of the smells of solvents. I can now clean my rifles in the house without inviting the wrath of my darling wife.” — Emmitt P. (Amazon)
“The MTM Patch Catcher works great! It is easy to adjust to different size barrels, and … all the gunk stays in the trap! Now, no more cleaning up the work bench/floor area after gun cleaning. This trap is a must have! I never knew I needed one of these until I got the MTM one from Graf’s. My buddy had a different brand, and it was hard to use. On his, the trap that holds the dirty patches and ‘juice’ would not stay in place, and some times most of the gunk ended up on the floor.” — Michael T (Grafs.com)
“This little device is more than a patch catcher. It also contains that dirty, smelly spray when a bore bristle exits the barrel. With the [MTM Patch Catcher] top open, it will also catch spray cleaners and lubes when used on small parts.” — TwoBoxer (Amazon)
Gun Variant Q & A — Yes it works with ARs and Muzzle Brakes
Q: Has anyone used this with an AR15?
Answer: It works quite well — goes on and off easily. Slide it on the barrel until you can tighten the strap behind the flash suppressor. — Cactus
Q: Does this fit securely if you have a standard muzzle brake?
Answer: Yes, I regularly use this product on all of my rifles including my Savage 111 Long Range Hunter with a factory brake. It really keeps the smell down with the top closed. Also stops the splatter of a stiff brush exiting the muzzle. Great Product! — Iklwa
Creedmoor Sports is a leading vendor of products for competitive shooters and serious hand-loaders. Along with great gear, Creedmoor Sports provides informative content for its customers. The Creedmoor InfoZone provides Reloading Tips, Gear Reviews, Shooting News, and basic gunsmithing information.
Bill Gravatt, President of Creedmoor Sports, is an expert on reloading processes and gear. He developed many of the popular tools marketed by Sinclair Int’l, and he brings that expertise to Creedmoor Sports. Bill hosts a series of “how-to” videos produced for the Creedmoor InfoZone.
In this video, Bill Gravatt demonstrates several methods to clean your cases. Bill tells us: “Powder residue should be removed before you insert your cases into your reloading dies. There are several ways to clean your cases. Many shooters use a combination of various methods…”
1. Manual Cleaning — You can use 0000 Steel wool for the outside of the case and a Case Neck brush for the inside. A paper towel can remove any remaining residue. This is a handy way to clean if you load at the range.
2. Vibratory Tumbling — This traditional method works well, particularly for pistol brass. Experiment with both Corn Cob and Walnut media. You can get a brighter shine by putting a small amount of liquid brass polish in the media.
3. Wet Tumbling with Stainless Media — This process can get your brass clean inside and out. Do check to ensure no pins are stuck in the flash-holes. Watch for peening of case mouths that can occur over time.
4. Ultrasonic Cleaning — Ultrasonic cleaning works great for small parts as well as brass. The ultrasonic process removes all carbon and traces of lube, which can leave the inside of case necks too dry. To smooth bullet seating, try putting a tablespoon of Ballistol in the cleaning solution.
Cleaning Reloading Dies
Cleaning your reloading dies is something that many hand-loaders neglect. In this 60-second Tech Tip, Bill Gravatt provides some smart advice on cleaning your dies. Bill notes: “After heavy use, case lube and carbon can build up in your reloading dies. It’s important to keep them clean. Also, with new dies, give them a good cleaning before first use, because they ship with a corrosion inhibitor.”
1. Step 1 — Prior to cleaning, disassemble the die and spray it with a good degreaser. Do this with brand new dies too.
2. Step 2 – Take a patch and run it in the die to remove old lube and gunk. Don’t forget the decapping assembly and other internal parts.
3. Step 3 — After cleaning the die, but before reassembly, spray the die with a good corrosion inhibitor, such as Corrosion-X or Starrett M1.
Among AccurateShooter’s most-visited web pages have been powder relative burn rate reference guides ranking powders from fastest to slowest. Here is the latest version of the Powder Burn Rate Table. Compiled by Hodgdon Powder Co., this Burn Rate Chart displays the relative burn rates of 176 different powders. Shown below is the latest table, released by Hodgdon in July 2024.
You’ll want to download this Powder Burn Rate Chart PDF. This 176-entry comparison table provides vital information for hand-loaders — with tested burn-rates. Note — this invaluable chart is not limited to Hodgdon and IMR propellants. This burn rate chart includes powders from eight major powder-makers: Accurate, Alliant, Hodgdon, IMR, Norma, Ramshot (Western), Vihtavuori, and Winchester.
