Sinclair International has a helpful, three-part video series on Full-Length Sizing. The full-length sizing die performs multiple important functions: it resizes the case body, resizes the neck, and adjusts the headspace relative to the chamber (it can also eject the spent primer if that was not done previously).
While neck-sizing-only can work with moderate loads (for a couple firings), after repeated firings the case can stretch, becoming too tight to chamber easily. If you shoot cases with high-pressure, near-max loads, you will probably benefit from full-length sizing your cases each reloading cycle. When full-length sizing, you will want to move the shoulder back (i.e. “bump” the shoulder) to provide proper clearance in the chamber. A case that has grown too much will exhibit stiff bolt lift after firing and be hard to chamber if it is not FL-sized during the reloading process.
Sinclair recommends bumping cases .001-.002″ (one to two thousandths) for cases used in bolt-action target-shooting rifles, or .003-.005″ (three to five thousandths) for hunting rifles or semi-auto rifles. To move the shoulder back you screw the FL-sizing die downwards in the press once you’ve determined “just touching” on the shoulder. You don’t have to screw the die down very far! With a normal 14-pitch die, 1/8th turn (45° rotation) yields approximately 0.009″ of downward movement. So it doesn’t take much to add a few thousandths of bump.

Widener’s Reloading & Shooting Supply recently published a helpful introduction to reloading powders. Widener’s online Guide to Smokeless Powders shows the various types of powders, and explains how the differences in powder kernel/flake size and shape, and burn rate affect performance. We recommend you visit Widener’s website and read the Powder Guide in full.
Take a close look at these illustrations which show the key differences between the four main powder types: extruded (stick) powder, ball (spherical) powder, flattened ball powder, and flake powder.
Burn Rate Basics
Widener’s Guide to Smokeless Powders also has a useful discussion of Burn Rate (a confusing topic for many hand-loaders). Wideners explains: “While a gun powder explosion in the cartridge seems instantaneous, if you slow it down you will actually find that each powder has a different ‘burn rate’, or speed at which it ignites.” This video shows powders with two very different burn rates. Watch closely.
Different burn rates suit different cartridge types notes Widener’s: “In general a fast-burning powder is used for light bullets and low-speed pistols and shotguns. Medium-rate powders are used for magnum pistols, while high-velocity, large bore rifle cartridges will need slow powders[.]
It should be noted that burn rate does not have a standardized unit of measurement. In fact, burn rate is really only discussed in comparison to other powders; there is no universal yardstick. Specifics will change by cartridge and bullet types[.]”
We are saddened to report that Mike Dillon, founder of Dillon Precision, has left the range. Mike, whose progressive loaders revolutionized the reloading industry, passed away just before Election Day. His company issued this notice:
“It is with heavy hearts that we announce the passing of Mike Dillon. Mike left us on the morning of November 7th, 2016. He leaves behind a large family including wife Carol, sons Stephen and Christopher, daughter Stephanie, and 9 grandchildren. Mike’s legacy has touched the lives of countless people worldwide. He revolutionized the ammunition reloading industry and made it what it is today. Mike also redesigned and manufactured the M134 Minigun that is now in service in the United States and foreign military forces. As a passionate aviator, he worked for TWA as a Second officer for 13 years and later made a name for himself as a writer for Air Progress Magazine. He is recognized by some as being the one who started the warbird restoration movement in the 1960s.
Mike’s dedication to his family, his customers, and this country was exemplary. We hope to continue the legacy that Mike Dillon worked so hard to build and we will never forget the impact that he has had on us all.
We take comfort knowing he is flying in the blue skies of heaven above.”
Leading figures in the shooting sports mourned Mike’s passing:
“Mike Dillon is a true inventor and pioneer in the shooting community. Shooters everywhere have benefitted from Mike’s affiliation with the best people and listening to their suggestions.” — Michael Voigt
“Since Mike Dillon has been involved with the shooting community, it is impossible to estimate the impact of his incredible ingenuity and generosity.” – Brian Enos
“This is very sad, Mike was a GREAT man. I had the privilege of photographing him in the mid 90s, he was very humble and generous soul. Mike changed the reloading industry FOREVER.” — Yamil Sued
Mike Dillon Content on Facebook
During the coming months Dillon Precision will publish many of Mike’s articles, videos, and photographs on the Dillon Precision Facebook Page. One of the first items released was the classic Machine Gun Magic video, showcasing the M134 Mini-Gun Mike Dillon invented.
At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.
1. Amazon — Howard Leight Electronic Muffs, $26.99
Act quickly — this is a DEAL of the DAY on Amazon! We’ve never seen a lower price on these popular electronic muffs, which are Amazon’s #1 seller in the category. The price goes back up tomorrow! Every shooter should own a pair of electronic muffs, even if you prefer shooting with earplugs and/or standard muffs. Electronic muffs are great when you are doing spotting duties or are working near the firing line. They allow you to hear ordinary conversations while still providing vital hearing protection. Right now Amazon.com has the Howard Leight Impact Sport Electronic Muffs on sale for just $26.99 (Deal of the Day). See All Price Options. NOTE: For regular, sustained shooting we recommend muffs and/or earplugs with a higher NRR rating.
2. CDNN Sports — Ruger American Ranch Rifle (Tan), $349.99
Here’s a nice little varmint rifle from Ruger with good features and performance at a killer price: $349.99. You could pay that much just for a barrel. This .223 Rem rifle features a 16.5″ hammer-forged barrel barrel threaded 1/2″-28 at the muzzle for brake or suppressor. The action, which features a 70° three-lug bolt, and Picatinny-style scope rail, sits in an aluminum bedding block. The crisp trigger adjusts down to 3 pounds. With a weight (before optics) of 6.1 pounds, this is a handy carry-around varminter. We like this rifle. For $349.99 it’s a steal.
3. Amazon — Caldwell Long Range Target Cam System, $329.49
Forum members have purchased this Caldwell Target Cam System and they’ve found that it works reliably, providing a clear signal to any WiFi-enabled mobile device (smartphone, iPad, Laptop). One member specifically tested the unit at 1000 yards and it functioned fine. NOTE: This system does NOT have a zoom camera lens, so you need to position the camera within 10 yards or so of the target. But if you place it to the side a bit, this shouldn’t be a problem. This system comes with a nice, fitted carrying case that holds camera, transceivers, antennas, and stands. You get a very capable system for under $330.00 (Amazon price includes free shipping for Prime members). You can also get this system from Midsouth for $357.02 (shipping extra).
Got patches? Here’s a great deal on 100% cotton flannel patches. There are many sizes available, starting at $8.99 for 800 one-inch “17 Cal” patches. For 6mm rifles, we actually like the 1.25″ round “22/223″ sized patches priced at $11.99 for 800. Choose either round patches or square patches in most sizes. We generally like round patches for use with spire-tip jags, but some shooters prefer to wrap their patches around a jag or brush and square patches work better for wrapping. The large, 2″-square .30 Cal patches cost $17.99 for 800.
5. Amazon — Frankford Quick-N-EZ Case Tumbler, $34.99
Look no further for a great deal on a reliable tumbler. We’ve used this very same machine to tumble both pistol brass and rifle cases. We like the see-through, transparent top and the large capacity — this will hold up to 350 .223 Rem cases. With 1000+ customer reviews on Amazon.com, this Frankford Quick-N-Easy Case Tumbler has earned a 4.5-star rating. If you need a tumbler, you might want to order soon — this is the best price we’ve seen in a while.
6. CDNN Sports — 45 ACP Ruger American Pistol, $399.99
At $399.99, this modern .45 ACP Ruger American Pistol costs hundreds less than premium polymer handguns from Europe. Compared to a Glock 21, it has better sights, a better trigger, and better ergonomics. Compared to an HK USP it has a lower bore axis and is way less expensive. FYI the Ruger’s low bore axis really does reduce felt recoil. The Ruger American pistol has interchangable grip panels so you can adjust the grip to your hand size. Controls are ambidextrous. Bottom line, this is a very good gun that gives up little to Glock, HK, and Walther. Buy American and save hundreds.
The RCBS Rock Chucker remains a classic — a big, strong, versatile press that can handle most reloading chores with ease. And now you can get a genuine Rock Chucker Supreme for $126.99 — a very good deal. The Rock Chucker offers plenty of leverage for case-sizing and the “O” is tall enough for long cartridges. The Rock Chucker has a very strong base and should last a lifetime. We’re not fans of the Rock Chucker’s priming system but most serious reloaders use a separate priming tool.
8. RCBS — Buy Green, Get Green Rebate
RCBS is running a very attractive Rebate Program currently. If you spend $300.00 on qualifying products you get a $75.00 rebate. Spend $50 and get a $10.00 Rebate. This program is limited to one (1) rebate redemption per calendar year, with a maximum of $75.00. CLICK HERE for more information.

Need quality .22 LR rimfire ammo at an affordable price? Consider Norma. Most folks think Norma only produces centerfire ammo and cartridge brass. As a result, people haven’t been looking for Norma rimfire ammo. Their loss is your gain. Accurate, reliable Norma .22 LR ammunition is in-stock right now at leading online vendors. This is good quality ammo, made in Europe. Bullets.com has Norma Tac-22 ammo in stock at $5.25 per 50-rd box (SKU: BL7819). In addition, Bullets.com offers Norma Match-22 ammunition at $7.50 per 50-rd box (SKU: BL11887).
NOTE: Despite the “BLK” in the name, this is a NOT a black powder substitute. This is a modern smokeless powder suitable for a wide variety of popular cartridges.
Hodgdon has announced a new “faster” variant of its popular CFE 223 powder. That’s good news for shooters of small varmint cartridges. Hodgdon’s new CFE BLK (named after the .300 AAC Blackout cartridge) has a faster burn rate than the original CFE 223. That makes CFE BLK ideal for small cartridges such as the .17 Hornet and .221 Fireball. The original CFE 223 propellant was formulated for reduced copper fouling (“CFE” in the name refers to “Copper Fouling Eraser”). New CFE BLK shares this reduced fouling technology which was developed originally for the U.S. military. Many of our Forum members have tried CFE 223 and confirmed that is performs “as advertised” — with less copper fouling that most other propellants. That’s a big benefit for varmint shooters, who may put hundreds of rounds through a barrel in a single day on the varmint fields.
Optimized for the .300 AAC Blackout cartridge, CFE BLK works great for .300 Blackout loads in AR-type rifles throughout the range of bullet weights. Moreover, CFE BLK is perfect for subsonic, reduced loads. In addition, Hodgdon reports that CFE BLK performs superbly in many smaller-capacity cartridges, in particular varmint cartridges such as the .17 Hornet, .17 Ackley Hornet, .218 Bee, .221 Fireball. CFE BLK is also well-suited for the 6.8 Remington SPC and the 7.62X39 Russian cartridge.
CFE BLK Meters Well and Burns Clean
CFE BLK is a spherical (ball) powder. Hodgdon reports the CFE BLK meters well, allowing reloaders to throw very consistent charges every time: “This fine powder meters like a dream and leaves no copper residue, extending accuracy for longer shooting periods, and making clean-up quick and easy.”
CFE BLK Should Be on Dealers’ Shelves in January 2017
Starting in January, 2017, CFE BLK powder will be available in both one-pound (1-lb.) and eight-pound (8-lb.) containers. Check with leading vendors such as Bruno’s, Midsouth, and Powder Valley. By the end of 2016, you should find complete load data for CFE BLK on the Hodgdon Reloading Data Center at www.HodgdonReloading.com.
When we first ran this story a while back, it generated great interest among readers. By popular request, we’re reprinting this story, in case you missed it the first time around. — Editor
Precision shooters favor premium brass from Lapua, Norma, or RWS. (Lake City also makes quality brass in military calibers.) Premium brass delivers better accuracy, more consistent velocities, and longer life. Shooters understand the importance of good brass, but many of us have no idea how cartridge cases are actually made. Here’s how it’s done.
The process starts with a brass disk stamped from strips of metal. Then, through a series of stages, the brass is extruded or drawn into a cylindrical shape. In the extrusion process the brass is squeezed through a die under tremendous pressure. This is repeated two or three times typically. In the more traditional “draw” process, the case is progressively stretched longer, in 3 to 5 stages, using a series of high-pressure rams forcing the brass into a form die. While extrusion may be more common today, RWS, which makes some of the most uniform brass in the world, still uses the draw process: “It starts with cup drawing after the bands have been punched out. RWS cases are drawn in three ‘stages’ and after each draw they are annealed, pickled, rinsed and subjected to further quality improvement measures. This achieves specific hardening of the brass cases and increases their resistance to extraordinary stresses.” FYI, Lapua also uses a traditional draw process to manufacture most of its cartridge brass (although Lapua employs some proprietary steps that are different from RWS’s methods).
After the cases are extruded or drawn to max length, the cases are trimmed and the neck/shoulder are formed. Then the extractor groove (on rimless cases) is formed or machined, and the primer pocket is created in the base. One way to form the primer pocket is to use a hardened steel plug called a “bunter”. In the photos below you see the stages for forming a 20mm cannon case (courtesy OldAmmo.com), along with bunters used for Lake City rifle brass. This illustrates the draw process (as opposed to extrusion). The process of draw-forming rifle brass is that same as for this 20mm shell, just on a smaller scale.
River Valley Ordnance explains: “When a case is being made, it is drawn to its final draw length, with the diameter being slightly smaller than needed. At this point in its life, the head of the draw is slightly rounded, and there are no provisions for a primer. So the final drawn cases are trimmed to length, then run into the head bunter. A punch, ground to the intended contours for the inside of the case, pushes the draw into a cylindrical die and holds it in place while another punch rams into the case from the other end, mashing the bottom flat. That secondary ram holds the headstamp bunter punch.
The headstamp bunter punch has a protrusion on the end to make the primer pocket, and has raised lettering around the face to form the headstamp writing. This is, of course, all a mirror image of the finished case head. Small cases, such as 5.56×45, can be headed with a single strike. Larger cases, like 7.62×51 and 50 BMG, need to be struck once to form a dent for the primer pocket, then a second strike to finish the pocket, flatten the head, and imprint the writing. This second strike works the brass to harden it so it will support the pressure of firing.”
Thanks to Guy Hildebrand, of the Cartridge Collectors’ Exchange, OldAmmo.com, for providing this 20mm Draw Set photo. Bunter photo from River Valley Ordnance.
If you’re shopping for a heavy-duty, single-stage reloading press, there’s a new option you should consider. MEC, noted for its shotshell reloading machines, has just introduced an all-new, cast-iron press, the MEC Marksman press. This new single-stage press has features we really like. First, the beefy, cast-iron frame is strong enough for the toughest reloading jobs. Second, the MEC Marksman features an OPEN front — that smart design makes it easier to insert and remove cartridge cases during the reloading process. It also makes it much easier to place your bullets during the seating stage. This open-front design makes good sense — note that Hornady’s new LNL single-stage press also has an open-front layout for important reasons. Lastly the MEC Marksman has an innovative, self-centering shell-holder. This patent-pending design should help hand-loaders reload more efficiently.
MEC MARKSMAN
Manufacturer’s Product Description
The MEC Marksman is made from ductile cast iron for superior quality and durability. Our patent-pending self-centering shell holder provides greater accuracy and consistency to every reload. The MEC Marksman is compatible with all 7/8-14 thread dies to change calibers quickly. Reload .22 Hornet to .416 Rigby all with one convenient machine. The MEC Marksman single-stage metallic reloader and accessory products are made in the USA in Mayville, Wisconsin.
In addition to the MEC Marksman, MEC’s new Metallic line of products will include reloading accessories. Powder measure, powder trickler, scale, and calipers will be offered. An additional base is available for easy installation and is compatible with the MEC Jig Fixture mounting system. Case prep tools and components are also available.
We are sad to report that long-time Forum member Frank S. (aka fdShuster) passed away last year. 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. This lets you find your MAX trim-to-length for any chamber. 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 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.
At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Bargain selections.

5. Walther — New 9mm CREED Pistol, $399.00 MSRP
Walther’s compact pistols have class-leading ergonomics and smooth trigger pulls that beat the competition. And now you don’t have to pay a premium for Walther quality. Walther’s new Creed 9mm pistol has an MSRP of just $399.00, and expect “street price” to be even lower. That makes the new Creed way more affordable than a Glock or HK. The Creed has a slide similar to Walther’s flagship PPQ with the pre-cocked hammer-fired action of the PPX. Like the PPX and PPQ, the Creed is a mid-size, double-stack service pistol chambered for 9mm Luger. Reviewers at GunsAmerica like this pistol: “[The Creed] marries Walther’s pre-set hammer-fired action with the good looks and curved surfaces of the company’s higher-end products.”
The Hornady Lock-N-Load AutoCharge Electronic Scale/Dispenser is now on sale for just $169.99 at Natchez Shooters Supply.

9. Gander Mtn. — American Eagle .22 LR Ammo, $2.49 for 40 Rds
We couldn’t run a Deals of the Week feature without a great ammo deal. Here’s a great price on .22 LR rimfire ammo for fun-shooting, plinking, and tactical cross-training. Right now Gander Mountain is selling forty (40) rounds of Federal American Eagle .22 LR copper-top rimfire ammo for just $2.49. Grab it while you can. There is a limit of 5 boxes per order at this price. Note — this is a 40-round box, not the normal 50-round box.
One of our Forum members asked us the question: “Does anybody make a good range box with cradles for cleaning at the bench?” The answer is yes — the MTM model RBMC Range Box offers slide-in plastic cradles that provide a reasonably sturdy platform for a quick clean when you’re done shooting. The RBMC box also offers plenty of storage for jags, brushes, solvents, ammo boxes and other miscellaneous gear you need for the range.
Among the many range boxes available, the MTM model RBMC Range Box leads the pack in terms of versatility. It is rugged, it has plenty of storage space, and it doubles as a handy cleaning station. This Editor has used the MTM Range Box to clean rifles and as a “range expedient” rifle holder when adjusting scopes and tensioning action screws. It’s a good product that does the job and stands up to rough handling.
Fitted Cleaning Cradles
The key feature setting MTM’s RBMC apart from most range boxes is the rubber-coated cradle system. Wide enough to fit a 3″-wide fore-arm, the cradles slide into vertical slots on either end of the box. This allows your range box to serve as a maintenance station. The RBMC is really pretty stable in this role, and the cradles won’t mark your stock. The cradles even feature slots on each side to hold your cleaning rods. The MTM Range Box is secure enough to stay in place when you’re brushing the barrel. However, if you’re working on a carpeted bench top, keep one hand on the box when running a cleaning rod through the bore, just to ensure the box doesn’t slide.
Versatile Upper Tray with Dividers
The MTM Range Box has two major components — the box base (with cradles), and a large upper tray with hinged top and carry handle. This large upper tray clamps securely to the bottom unit for transport. The top tray has a long section that holds cleaning rod guides, long brushes, grease syringes and the like. There are two, clear-plastic fitted divider trays. These will hold your patches and jags, plus comparators, ring wrenches, and other small tools.
What Might Be Improved
Though we really like the MTM Range Box, it’s not perfect. First, we wish the box was a bit deeper, to have added carrying capacity. The dimensions of the MTM Range Box are: 25″ long x 11.5″ wide x 8.75″ high. We’d like to see it 12″ high/deep to allow larger solvent bottles to stand upright and to provide more space to carry tools and shooting muffs. However, it is deep enough to hold the large 100-round MTM cartridge boxes that are popular with many shooters (see photo at right).
While we like the twin clear plastic dividers that fit into the removable top-tray, but we wish the dividers had individual hinged tops. This would keep small items more secure.
The MTM Shooting Range Box RBMC-11 (green version) is on sale now for $39.03 at Amazon.com, with FREE shipping. MTM also offers a black “tactical” version of this product for a bit more money ($43.93 at Amazon). This Tactical Range Box includes a special bracket that supports AR-type rifles through the magazine well.
