Ever wondered what caused a particular bulge or marking on a case? And more importantly, does the issue make the case unsafe for further use? Sierra Bullets Ballistic Technician Duane Siercks offers some insight into various issues and their causes in two Case Diagnostic articles from the Sierra Blog.
Incipient Case-Head Separation
This is a Winchester .308 Win case that has a real issue. This case has a very obvious incipient case head separation in the process of becoming a complete failure.
This is most commonly caused by over-sizing the case causing there to be excess headspace on the case. After a few firings and subsequent re-sizing, this case is just about ready to come completely apart. Proper die adjustment is certainly a requirement here. Of course this case is not safe to reuse.
Excessive Pressure (Load Too Hot)
If you will notice in the picture of the case rim, there are two pressure signs to notice. First, look at the primer. It is basically flattened to about the max of what could be considered safe. If this was the only pressure sign noted, I would probably be fine with this load, but would constantly keep an eye on it especially if I was going to use this load in warmer temperatures. This load could easily cross into the “excess pressure” realm very quickly.
There is another sign of pressure that we cannot ignore. If you’ll notice, there is an ejector mark apparent that is located over the “R” of the R-P headstamp. This absolutely tells us that this load would not have been in the safe pressure range. If there were any of these rounds loaded, they should not be fired and should be dis-assembled. This case should not be reloaded.
Split Case-Neck
Here we have an R-P .22-250 case that has died the death. Everything looks fine with this case except the neck is split. This case must be tossed.
A split neck is a normal occurrence that you must watch for. It is caused by work-hardening of the brass. Brass cases get harder with age and use. Brand new cases that are stored for a period of time can become hard enough that they will split like this case within one to two firings. I have had new factory loads do the same thing. Then as we resize and fire these cases repeatedly, they tend to get harder and harder. Eventually they will split. The life of the case can be extended by careful annealing practices. This is an issue that would need to be addressed in an article by itself. Of course this case is no longer usable.
In the classes that I teach, I try to use examples like this to let the students see what they should be looking for. As always, if we can assist you, whether you are new to reloading or very experienced, contact us here at Sierra Bullets by phone at 1-800-223-8799 or by email at sierra@sierrabullets.com.
Dented Case Body
Here we have a Lake City 7.62×51 (.308 Win.) case with two heavy marks/dents in the case body.
This one may be a bit of a mystery. It appears as if this case may have been caught in the action of a semi-auto rifle when the firearm jammed or the case failed to clear during the cycling process. I probably would not reload this case just to prevent any feeding problems. This also appeared to be a factory loaded round and I don’t really see any pressure issues or damage to the case.
Multiple Problems — Lake City 5.56×45 unknown year.
This case has suffered multiple failures and cannot be re-used. First its has have a very rounded shoulder that is split. Upon first look it was obvious that this round had been a victim of excess pressure. The firearm (perhaps an AR?) was apparently not in full battery, or there was possibly a headspace issue also. While taking a closer look, the primer was very flat and the outside radius of the primer cup had been lost. High pressure! Then I also noticed that there was an ejector mark on the case rim. This is most certainly an incident of excessive pressure. This case is ruined and should be discarded.
It is very important to observe and inspect your cases before each reloading. After awhile it becomes second nature to notice the little things. Never get complacent as you become more familiar with the reloading process. If ever in doubt, call Sierra’s Techs at 1-800-223-8799.
Looking for a good load for a new rifle? Or perhaps you want to try a new powder and bullet combo for an existing rig. One of the best places to start for load data is Hodgdon’s online Reloading Data Center for pistol, rifle, and shotgun reloaders. Check out the Reloading Data Center at www.HodgdonReloading.com.
In the Data Center, you’ll find thousands of load recipes for pistol, rifle, and shotgun. Rifle shooters will find dozens of loads for their favorite Hodgdon, IMR, and Winchester powders such as H4198, H4895, Varget, H4350, and IMR 8208 XBR. And Hodgdon’s Reloading Center is “mobile-friendly” so it works well with smartphones and tables. Navigation is easy, and you can set the search criteria easily choosing your favorite powder or bullets. After choosing a cartridge, you can pre-select specific bullet weights and powder types. That quickly delivers just the information you want and need. You won’t have to scroll through scores of entries for bullets or powders you don’t use.
Mobile users will notice that the current Hodgdon Reloading Center is much more “user-friendly” for smart-phone and tablet users. Controls have been optimized for touch-screens, and buttons are large and easy to use. Likewise the results are displayed in a large, easy-to read format.

Here’s something you’ve never seen before — a full-size rifle chambered for the tiny 7.62×25 Tokarev round. This rifle was a fun project by Les E., aka “scasa” in our AccurateShooter Forum. This is a true “home-built” rifle. Les machined the action himself (receiver AND bolt), chambered the barrel, and crafted the stock from a blank. You’ll find complete build details (with machining photos) in this Forum Thread.
Why did Les build this unique rifle? He tells us: “I just thought it would make a nice little rifle cartridge with light bullets and subsonic with heavier ones. D.J. Jones had something similar as the ‘Mini Whisper’.”
Les designed and built the action and bolt to fit the tiny 7.62×25 Tokarev cartridge. He told us: “Once upon a time I got this idea to make a bolt action with front locking lugs, full diameter bolt, Remington trigger. It took me years to get it all figured out and make all the tooling, then it took about six months to build the gun”. The rifle features a 1:10″-twist Adams & Bennett barrel that Les chambered himself.
Les designed and crafted the receiver and bolt assembly himself. The bolt features an extractor but not an ejector — the empty case stays on the end of the bolt. The extractor slot cuts through one lug, but Les says it still has 10 times the required strength.
Details of Action Design and Machining
Les explained: “The action started as a piece of 4160 bar stock. I drilled and reamed all the holes in my 12×36 Craftsman lathe. Cutting the slot inside for the locking lugs to pass through was the most difficult part. There were no blueprints for this and just a couple of sketches to get the slots right for the bolt handle slot and extraction cams. Everything is design on the fly. I used a grade 8 bolt for the bolt which did not require any hardening, they’re pretty hard already. Although I did make several receivers before I got it figured out, I only made one bolt.”
Surprisingly, Les is not a machinist by trade. He is just a very smart guy who learned by doing: “I’ve never had any machinist training. I mostly learned by trying different things until I found what works.”
NOTE: Under Federal law, it is legal to build an action or complete rifle for personal use (not for resale). Refer to ATF Regulations.
As you might expect, this cartridge is naturally pretty quiet. Les says it “makes less noise than a .17 HMR”. Recoil is also minimal. In a 9-lb rifle (with scope), shooting free recoil, the rifle moves only about three inches. Considering this is a tiny pistol cartridge, the accuracy is pretty good, as you can see:
Loading for the 7.62×25 Tokarev in a Rifle
The cartridge brass comes from Sellier & Bellot pistol ammo. Les currently loads with AA #7 and AA #9 powders, but he may try some others. His favorite load so far has Hornady 168gr A-Max bullets pushed by AA #9 powder and CCI 400 primers. This produced a 0.437″ group at 50 yards.
How does Les like the cartridge? He says: “I wish the 7.62×25 had a longer neck. At 0.140″ it’s pretty short. I think a longer neck would help getting things lined up better.” He notes that boat-tail bullets seem to load easier than flat-base projectiles.
Ammo is loaded with inexpensive Lee dies: “I’m using Lee dies and they seem to work OK. I’d like a better seater die and I may modify this one.”
Les reports: “The 168gr Berger moly LTB didn’t do as well as the 168gr A-Max so I started working with the A-Max. I’m loaded really long and the Tokarev evidently has a pretty long freebore but I managed to get it into the lands. The target photo above is the best this gun has ever shot. I’ve gotten mostly two-inch groups at 50 yards (my max home range distance). Recently I made some progress. My best group was a little less than 1/2 inch at 50 yards.”
Special Features of the Stock
Les built the stock himself from a laminated blank. For this project, Les added some interesting features to the stock. He created his own adjustable cheekpiece using all home-crafted hardware.
Les also fitted a barrel tension adjustment system in the stock to help tune the barrel harmonics. There is a hex-head machine screw in the bottom of the stock for adjusting the upward tension on the barrel.
Les crafted this stock with a thumbhole pattern with finger grooves. He has used this design on other stocks he has built as he likes the look and “feel”.
Here’s the super-speedy way to turn case-necks. Our friend Erik Cortina figured out how to turn his match cartridge case-necks using his milling machine. Erik told us: “While in Raton [a while back], Mid Tompkins told me that he turns his brass on milling machine. He said he could do about 500 in two hours, so I decided to try it.”
Erik fitted a Don Nielson “Pumpkin” neck-turner to the mill, and he used a modified 21st Century case holder to secure the brass. As you can see from this video, Erik was very successful with the process. The tool spins at 1500 rpm, turning Lapua 6.5-284 cases that have been necked up to 7mm.
Video Shows Eric Cortina Neck-Turning Cases with Milling Machine:
Cartridge Brass: Lapua 6.5-284 necked up to 7mm
Lubricant: Lithium grease inside and outside of neck
Neck-Turner: Nielson Pumpkin running at 1500 RPM
It’s hard to argue with Erik’s results. Here are his turned Lapua cases, which have neck-wall thickness consistent to two ten-thousandths of an inch. Think you could do better turning manually?
Some of Erik’s Facebook friends had questions about this process:
Q: Who makes the shell-holder?
Erik Cortina: I did! The shell-holder you can get from 21st Century. I Tig-welded a punch as a handle.
Q: I love the idea of working smarter not harder! Any galling issues? What are your mitigation techniques?
Erik Cortina: No issues. I use lithium grease in spray can. Makes a foam that I dip necks into.
Q: Shouldn’t either the case or the cutter be floating to allow most precise neck turning?
Erik Cortina: Up until [I tried this] I believed the same thing. I was going to build a floating case holder but decided to try rigid setup on a few cases before I built it. Results were great. Neck thickness doesn’t vary more than .0002″, which is same as when I was doing it with floating case holder on the lathe.
Q: Any problems with the Pumpkin changing the cut as it heats up?
Erik Cortina: No — there were no issues with that.
NOTE: Erik Cortina is a very skilled machinist who custom-crafted fittings used for this process. This kind of neck-turning with a milling machine may not be for the everyday hand-loader!
Nielson “Pumpkin” Neck-Turner
The circular orange cutting fixture on Erik’s Milling Machine is a Don Nielson “Pumpkin” neck-turning tool. Don designed this tool to be used by hand or with power. The Pumpkin boasts an eccentric mandrel that allows the cut to be adjusted easily in precise .0001″ increments. Benchresters like this as it allows for very precise control of cut depth and neck-wall thickness.

Here’s an inexpensive product that can make your case prep and loading tasks easier. We use and recommend the cleverly-designed Lyman Bleacher Blocks. These multi-level (stepped) cartridge holders save space on your bench AND make it easier to select a particular case/cartridge from a full block. Each row is a different height for convenience. With Bleacher Blocks it’s also easier to check for powder levels, or place bullets before the seating process.
Lyman’s Bleacher Block cartridge holders have many advantages over conventional, single-level blocks. Use the different levels for sorting brass. Or, migrate the brass from top to bottom as you proceed through case prep stages. If you are assembling loads with different bullets for load testing, you could arrange the loaded rounds on different levels for easy recognition. For example put V-Max loaded rounds on the top tier, and Berger Hybrid loaded rounds on the bottom tier. Or, if you are experimenting with neck tension, you can use different rows for cases processed with different bushings.
Made of durable orange polymer, Lyman Bleacher Blocks are molded in three sizes. The smallest size (with 0.388″-diam holes) fits .223 Rem-size case heads. The middle size (with 0.485″-diam holes) fits .308 Win-size case heads. That works for 6mmBR/Dasher sized cases perfectly. The biggest Bleacher Block has 0.565″-diameter recesses for magnum-size cases. All three cartridge block sizes hold fifty (50) rounds. Purchase any size for just $6.14 per Block at Midsouth.
Here’s what Lyman says about its innovative cartridge block design: “Our [stepped] loading blocks allow for easier handling of cases in and out of the loading block. Our stepped design allows you to easily grip a single case without jamming your fingers down into a group of cases like in traditional loading blocks, and allows for a smaller ‘footprint’ on your bench.”
Lyman Bleacher Blocks are among the Reloading Tools reviewed in this helpful video:
One of our Forum members complained that he wasn’t able to set his primers flush to the rim. He tried a variety of primer tools, yet no matter what he used, the primers still didn’t seat deep enough. He measured his primers, and they were the right thickness, but it seemed like his primer pockets just weren’t deep enough. He was mystified as to the cause of the problem.
Well, our friend Boyd Allen diagnosed the problem. It was the decapping rod. If the rod is adjusted too low (screwed in too far), the base of the full-diameter rod shaft (just above the pin) will contact the inside of the case. That shaft is steel whereas your case is brass, a softer, weaker metal. So, when you run the case up into the die, the shaft can actually stretch the base of the primer pocket outward. Most presses have enough leverage to do this. If you bell the base of the primer pocket outwards, you’ve essentially ruined your case, and there is no way a primer can seat correctly.
The fix is simple. Just make sure to adjust the decapping rod so that the base of the rod shaft does NOT bottom out on the inside of the case. The pin only needs to extend through the flash hole far enough to knock the primer out. The photo shows a Lyman Universal decapping die. But the same thing can happen with any die that has a decapping rod, such as bushing neck-sizing dies, and full-length sizing dies.
Whenever you use a die with a decapping pin for the first time, OR when you move the die to a different press, make sure to check the decapping rod length. And it’s a good idea, with full-length sizing dies, to always re-check the height setting when changing presses.
There are a variety of decapping dies currently on the market, with models available from Lee, Lyman, Hornady, RCBS, Redding, and Sinclair Int’l.
Lee Universal Decapping Die on SALE for $10.96
Speaking of decapping tools, Midsouth Shooters Supply sells the Lee Universal Decapping Die for just $10.96 (item 006-90292), a very good deal. There are many situations when you may want to remove primers from fired brass as a separate operation (prior to case sizing). For example, if your rifle brass is dirty, you may want to de-cap before sizing. Or, if you load on a progressive press, things will run much more smoothly if you decap you brass first, in a separate operation.
Decapping Dies for Cases with Smaller Flashholes
TAKE NOTE: Some Euro Small Flash Holes are spec’d at 1.5mm or 0.059″, and max out at about .062″, so these need a smaller die pin.
The low-cost Lee Universal Decapping Die will work with cartridges from 17 Fireball all the way up to big Magnums. However, NOTE that the decapping pin supplied with this Lee die is TOO LARGE for LAPUA 220 Russian, 6mmBR, 6.5×47, 6.5 Creedmoor, .308 Win (Palma) and Norma 6 PPC flash holes. Because the pin diameter is too large for these brass types, you must either turn down the pin, or decap with a different tool for cases with .059-.062″ flash-holes.
Sinclair Int’l offers a Stainless Decapping Die that comes with both .080 and .060 Pins. The $34.99 die ships with three decap pins for standard .080″ flash holes, and two pins for .060″ flash holes
Redding makes a Universal Decapping Die with an optional smaller-diameter decapping rod for the smaller .059-.062″ flash holes found on the BR and PPC cases. The use of this die is explained in the video below:
He who dies with the most toys wins — right? Well Sinclair has another interesting gadget you can add to your reloading bench. The Sinclair Case Neck Sorting Tool lets you quickly sort brass by neck-wall thickness. For those who shoot “no-turn” brass, this can improve neck-tension consistency. Large variances in neck-wall thickness can cause inconsistent neck “grip” on the bullet. Generally, we’ve found that more consistent neck tension will lower ES and (usually) improve accuracy. We know some guys who shoot no-turn 6mmBR brass in competition with considerable success — but their secret is pre-sorting their brass by neck-wall thickness. Cases that are out-of-spec are set aside for sighters (or are later skim-turned).
Watch Case Neck Sorting Tool Operation in Video
How the Case Neck Sorting Tool Works
Here’s how the Sinclair tool works. Cases are rotated under an indicator tip while they are supported on a case-neck pilot and a support pin through the flash hole. The unit has a nice, wide base and low profile so it is stable in use. The tool works for .22 through .45 caliber cases and can be used on .17- and .20-caliber cases with the optional carbide alignment rod. The MIC-4 pin fits both .060 (PPC size) and .080 (standard size) flash holes. Sinclair’s Case Neck Sorting Tool can be ordered with or without a dial indicator. The basic unit without dial indicator (item 749-006-612WB) is $59.99. The tool complete with dial indicator (item 749-007-129WB) for $89.99. IMPORTANT: This tool requires caliber-specific Sinclair Case Neck Pilots which must be ordered separately.
Editor’s Comment: The purpose of this Sinclair tool is rapid, high-quantity sorting of cartridge brass to ascertain significant case-neck-wall thickness variations. Consider this a rapid culling/sorting tool. If you are turning your necks, you will still need a quality ball micrometer tool to measure neck-wall thickness (to .0005) before and after neck-turning operations.
In the ELR game, particularly the King of 2 Miles (KO2M), it’s “go big or go home”. The top shooters run large-capacity cartridges that push large-caliber, ultra-high BC bullets at very high velocities. Bullets launched by cartridges such as the .416 Barrett can sustain supersonic velocities at Extreme Long Ranges — and that’s what it takes to win. The .416 Barrett can launch a 550-grain solid bullet at 3000+ FPS.

2018 and 2019 Kings of 2 Miles Loaded on RCBS Presses
So how do you load jumbo cartridges such as the .416 Barrett? It takes a big, heavy, super-strong reloading press. We’ve learned that the last two Kings of 2 Miles, Paul Phillips (2019) and Robert Brantley (2019) both loaded their KO2M ammo on RCBS AmmoMaster .50 BMG presses. Phillips loaded .416 Barrett ammo, while Brantley loaded custom .416 MCS rounds.
In 2018, Robert Brantley topped the field using his custom .416 MCS loads perfected on the AmmoMaster .50 BMG Press. This year, Brantley took a close second to 2019 KO2M winner Paul Phillips. Both Phillips and Brantley use the AmmoMaster .50 BMG single stage press kit and RCBS .416 Barrett dies to hand-load for extreme long-range. “My ammo has been much more consistent after switching to the RCBS press and dies,” remarked Phillips, who runs the Global Precision Group. Brantley said he uses RCBS products for most of his reloading needs — from the dies and AmmoMaster, to the ChargeMaster and Brass Boss. His custom .416 MCS loads launch a 550-grain bullet more than 3,100 fps.
Loading with RCBS AmmoMaster .50 BMG Press
This video shows reloading with the RCBS AmmoMaster .50 BMG press. While this video shows .50 BMG cases being loaded, the principles are the same for loading the .416 Barrett used by both Brantley and Phillips. Big cases need big presses!
Derek Rodgers Shooting the .375 CheyTac at K02M in 2017
Another ELR ace, 2017 King of 2 Miles champion Derek Rodgers, favored the .375 CheyTac cartridge. For his successful K02M quest, Derek ran Cutting Edge Bullets in Peterson brass with Hodgdon H50BMG powder. The video below shows Derek in action at the 2017 KO2M event.
The KO2M competition is a two-day extreme long-range (ELR) match held at the NRA Whittington Center outside Raton, New Mexico. Teams consist of one shooter and up to two wind coaches/spotters, who fire on steel targets ranging from about 1,500 to 3,500 yards.
Here’s something you’ve never seen before — a full-size rifle chambered for the tiny 
The cartridge brass comes from Sellier & Bellot pistol ammo. Les currently loads with AA #7 and AA #9 powders, but he may try some others. His favorite load so far has Hornady 168gr A-Max bullets pushed by AA #9 powder and CCI 400 primers. This produced a 0.437″ group at 50 yards.
