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 this article from the Sierra Blog.
Diagnosing Problems with Cartridge Brass
by Duane Siercks, Sierra Bullets
I was handed a small sample of .223 Rem cases the other day and was asked if I could comment on some marks and appearances that had been noticed as they were sorting through the cases. I will share what was observed and give you what would seem to be a cause for them. These were from an unknown source, so I have no way of knowing what type of firearm they were fired in or if they were factory loaded or reloaded ammunition.
Example ONE: Lake City 5.56, Unknown Year
Case #1 was seen to have a very rounded shoulder and 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. See photo below.
Example TWO: Lake City Match 1993
Case #2 appears very normal. There was some question about marks seen on the primer. The primer is not overly flattened and is typical for a safe maximum load. There is a small amount of cratering seen here. This can be caused by a couple of situations.
Cratering is often referred to as a sign of excess pressure. With safety in mind, this is probably something that should make one stop and really assess the situation. Being as there are no other signs of pressure seen with this case, I doubt that pressure was unsafe. That leads us to the next possibility. This can also be caused by the firing-pin hole in the bolt-face being a bit larger than the firing-pin, and allowing the primer to flow back into the firing-pin hole causing the crater seen here. This can happen even with less-than-max pressures, in fact it has been noted even at starting loads. Always question whether pressure is involved when you see a crater. In this situation, I lean toward a large firing-pin hole. This case should be safe to reload.
Example THREE: R-P .223 Remington
Case #3 appears normal with one exception. There are two rings seen about one half inch below the base of the shoulder. These rings are around the circumference of the case, one being quite pronounced, and the other being noticeably less.
As we do not know the origin of the firearm in which this case was fired, it does seem apparent that the chamber of the firearm possibly had a slight defect. It could have been that the reamer was damaged during the cutting of this chamber. I would suggest that the chamber did have a couple of grooves that imprinted onto the case upon firing. This firearm, while maybe not dangerous should be looked at by a competent gunsmith. In all likelihood, this case is still safe to use.
Example FOUR: R-P .223 Remington
Case #4 has no signs of excess pressure. There is a bulge in the case just ahead of the case head that some might be alarmed by. This bulge is more than likely caused by this case being fired in a firearm that had a chamber on the maximum side of S.A.A.M.I. specifications. There is actually no real issue with the case. Note that the primer would indicate this load was relatively mild on pressure.
If this case was reloaded and used in the same firearm numerous times there might be a concern about case head separation. If you were going to use this case to load in an AR, be sure to completely full-length re-size to avoid chambering difficulties. This case would be safe to reload.
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.
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 — Caldwell Long Range Target Camera System, $349.49
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 $350.00 (Amazon price includes free shipping for Prime members). You can also get this system from Midsouth for $357.02 (shipping extra).
2. Midsouth — Lyman BoreCam Digital Borescope, $222.46
Note: We are repeating this special because it is the best deal we’ve found on an excellent product in high demand. The Lyman BoreCam is an electro-optical borescope with a digital display. You can record “stills” on a SD card. This is one of the hottest products on the market right now — and users really like the BoreCam (although some wish the digital view-screen was larger). Midsouth Shooters Supply now has the Lyman BoreCam for $222.46. Grab it while you can at that price. Other online vendors are charging a LOT more (e.g. MidwayUSA price is $259.99).
We like reactive targets. It’s fun to “ring steel” and see a target move instantly when hit. For just twenty bucks (including shipping), it’s hard to go wrong with this 8″ AR500 Steel Gong. The 8″-diameter size is big enough for zeroing at 200 yards, yet offers a nice challenge at 500 yards and beyond. There is also a 6″-diameter model for $16.00.
Here’s a rifle with a smooth three-lug action and good trigger that can take any game in North America. The Browning A-Bolt is justifiably respected as a solid hunting rifle. The 300 Winchester Magnum chambering offers serious hitting power, even at long range. This rifle, with a blued barreled action, normally retails for $600.00+. Now it’s on sale for under $500.00. To sweeten the deal even more, right now Browning is offering $50 CASH BACK on Browning centerfire rifles purchased between August 1, 2016, and September 30, 2016. CLICK HERE for $50.00 REBATE FORM.
5. ULINE.com — 200 Pairs of NRR32 Ear Plugs for $19.00
Every shooter needs good hearing protection, and when you buy in bulk you can save big. Right now Uline.com is offering 200 pairs of NRR32-rated tapered foam ear plugs for $19.00. That’s a steal. Corded (linked) models are $36.00 for 200 pairs. This Uline offer is a great way to supply your local shooting club or youth marksmanship training program. NOTE: This deal expires 10/9/2016.
This is quality, CCI made-in-USA ammo with reloadable, brass casings. We have used this CCI-made Blazer 9mm ammo in Sig, HK, and Glock pistols and it performed very well. This stuff won’t last long at this price (less than $0.20 per round). If you need 9mm practice ammo, order soon — this very same 1000-round case of Blazer 9mm ammo costs $60.00 more at MidwayUSA. Blazer Brass is loaded in boxer-primed, reloadable brass cases for added value.
Here’s a good deal on the new Lyman 50th Ed. Reloading Manual. Our Forum members have rated this as the best Loading Manual for starting hand-loaders. This 50th Edition, the first to be produced in full color, includes more load data, and covers more cartridge and bullet types than ever before. This handbook has a strong heritage, starting with the Ideal/Lyman reloading manuals from the early 20th Century. Midsouth offers an excellent price — MidwayUSA sells this for $24.99.
Every gun owner should have a work mat to protect valuable firearms during cleaning and maintenance operations. Right now you can get a quality 36″x16″ mat for under ten bucks. The non-slip polyvinyl chloride (PVC) surface won’t harm gun’s finish, and its absorbent features keep the fluids from going through your work surface. This week Amazon is offering the Printed Version (shown above) for $9.99 and a Plain Black Version for just $8.09. That’s an excellent value either way.

1. Cabela’s — Rem 700 ADL Varmint, $309.99 with 10% Off Coupon and Remington $50.00 Rebate
OK, here’s the deal of the year for hunters. You can get a complete Remington 700 ADL Varmint Rifle in 22-250 or .308 Win for $309.99. That’s less than you might pay for a used Rem 700 action by itself. Here’s how it works. The current Cabela’s Sale Price is $399.99. Use online discount code STOCKUP16 to knock 10% off the price. That brings it down to $359.99. OK, there’s more — now through September 30, 2016, Remington is offering a $50 Mail-in Rebate on Rem 700 ADLs. When you get the $50.00 back from Remington, your net cost for this rifle is $309.99. CLICK HERE for Remington Rebate INFO.
IMPORTANT: Remington $50.00 Rebate valid on purchases made from 8/1/16 through 9/30/16. All Rebate requests must be postmarked by 10/29/16.
2. Midsouth — Alamosa Gun Case for 50″ Scoped Rifle
We’ve been looking for a jumbo, well-padded soft case like this for a long time. Something big enough to hold long-barreled match guns, with enough padding to protect nice finishes and enough room for tall scopes. We are impressed with the new Alamosa Gun Case from Allen Company, which holds guns up to 50″ in length. We measured a 28″-barreled bench gun and this case was just big enough. If you have an adjustable buttplate, muzzle brake, or tuner, you might need a longer case (measure your rifle before ordering the Alamosa case). There’s a lot to like with the Alamosa case. The pockets are large and the shape provides plenty of room for big optics. You can purchase this case from Midsouth for $43.05, or from Amazon.com for $48.46 with free PRIME shipping.
— Extra-wide design to accommodate bi-pods and large scopes
— Multiple External Pockets
— Rugged Endura fabric with soft-knit lining
— Lockable zippers, padded handle
3. Cabela’s — 10% Off Guns & Ammo + Free Shipping ($99 Min)
Cabela’s is having a big Sale on Firearms now, in advance of hunting season. You’ll find very competitive prices on rimfire and centerfire rifles.

4. CDNN Sports — HK 416 .22LR Rimfire Rifle, $379.99
If you are looking for an AR-type .22 LR rifle for cross-training and rimfire tactical matches, the HK 416 is a fine choice. Made by Walther under license, these HK 416 D145RS rimfire rifles are accurate and reliable. This is a good deal at $379.99! The HK 416 normally sells for $550.00 to $600.00. One purchaser writes: “Great .22. I have had this gun a couple of months and have put about 500 rounds of 5 different brands of ammo through it. Not one FTE. I have shot other brands that can’t get through one 30-round mag without a failure.” CLICK HERE for Product Details.
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).
6. Amazon — RAVPower 22000 mAh Battery Bank, $39.99
This is one of the most powerful, fast-charging USB-type power banks you can buy. Rated at 22000 mAh, it has 50% more “juice” than many units selling for around $35.00. This RAV Power machine charges up quickly and boasts three “intelligent” ports for optimal charging of smartphones, iPads, tablets, and other devices. After looking at a number of competitive battery banks, your Editor bought this RAVPower 22000 mAh unit to charge his own phone and iPad. It can deliver a total current output of 5.8A (2.4A max per port), allowing it to charge two iPads and one iPhone 6s at optimal charging speeds. This unit can also power a LabRadar Chronograph for a full weekend of shooting (6-7 hours per day).
Here is a very good deal on a decent 55-inch-high Stack-On Safe that offers a lot of capacity for the money. The claimed capacity is 24 long guns, that might work for smaller, unscoped rifles or shotguns. For scoped rifles, you might fit a dozen comfortably. There are convertible shelves that can hold handguns, optics, or other valuables. This safe will be delivered to your location — it is not available for in-store pick-up. Shipping surcharge applies. External Safe Dimensions are 55.00″ High x 29.25″ Wide x 20.25″ Deep. Shipping weight is 436 pounds.
For pure plinking fun, it’s hard to beat rimfire shooting at reactive targets. We’ve used this inexpensive Rimfire Spinner target, and it has proven easy to set up and durable. We like the fact that there are three target diameters (3 5/8″, 2 1/4″, 1 5/8″) — that let’s new shooters get their confidence. You can set this spinner target close for pistols or at 50 yards with .22 LR rifles. This Birchwood Casey Target is also offered by Amazon.com for $19.99 with FREE Prime Shipping.
Why You CANNOT Rely on the MV Printed on the Ammo Box!
When figuring out your come-ups with a ballistics solver or drop chart it’s “mission critical” to have an accurate muzzle velocity (MV). When shooting factory ammo, it’s tempting to use the manufacturer-provided MV which may be printed on the package. That’s not such a great idea says Bryan Litz of Applied Ballistics. Don’t rely on the MV on the box, Bryan advises — you should take out your chrono and run your own velocity tests. There are a number of reasons why the MV values on ammo packaging may be inaccurate. Below is a discussion of factory ammo MV from the Applied Ballistics Facebook Page.
Five Reasons You Cannot Trust the Velocity on a Box of Ammo:
1. You have no idea about the rifle used for the MV test.
2. You have no idea what atmospheric conditions were during testing, and yes it matters a lot.
3. You have no idea of the SD for the factory ammo, and how the manufacturer derived the MV from that SD. (Marketing plays a role here).
4. You have no idea of the precision and quality of chronograph(s) used for velocity testing.
5. You have no idea if the manufacturer used the raw velocity, or back-calculated the MV. The BC used to back track that data is also unknown.
1. The factory test rifle and your rifle are not the same. Aside from having a different chamber, and possibly barrel length some other things are important too like the barrel twist rate, and how much wear was in the barrel. Was it just recently cleaned, has it ever been cleaned? You simply don’t know anything about the rifle used in testing.
2. Temperature and Humidity conditions may be quite different (than during testing). Temperature has a physical effect on powder, which changes how it burns. Couple this with the fact that different powders can vary in temp-stability quite a bit. You just don’t know what the conditions at the time of testing were. Also a lot of factory ammunition is loaded with powder that is meter friendly. Meter friendly can often times be ball powder, which is less temperature stable than stick powder often times.
3. The ammo’s Standard Deviation (SD) is unknown. You will often notice that while MV is often listed on ammo packages, Standard Deviation (normally) is not. It is not uncommon for factory ammunition to have an SD of 18 or higher. Sometimes as high as 40+. As such is the nature of metering powder. With marketing in mind, did they pick the high, low, or average end of the SD? We really don’t know. You won’t either until you test it for yourself. For hand-loaded ammo, to be considered around 10 fps or less. Having a high SD is often the nature of metered powder and factory loads. The image below is from Modern Advancements in Long Range Shooting: Volume II.
4. You don’t know how MV was measured. What chronograph system did the manufacturer use, and how did they back track to a muzzle velocity? A chronograph does not measure true velocity at the muzzle; it simply measures velocity at the location it is sitting. So you need to back-calculate the distance from the chrono to the end of the barrel. This calculation requires a semi-accurate BC. So whose BC was used to back track to the muzzle or did the manufacturer even do that? Did they simply print the numbers displayed by the chronograph? What kind of chronograph setup did they use? We know from our Lab Testing that not all chronographs are created equal. Without knowing what chronograph was used, you have no idea the quality of the measurement. See: Applied Ballistics Chronograph Chapter Excerpt.
5. The MV data may not be current. Does the manufacturer update that data for every lot? Or is it the same data from years ago? Some manufacturers rarely if ever re-test and update information. Some update it every lot (ABM Ammo is actually tested every single lot for 1% consistency). Without knowing this information, you could be using data for years ago.
CONCLUSION: Never use the printed MV off a box of ammo as anything more than a starting point, there are too many factors to account for. You must always either test for the MV with a chronograph, or use carefully obtained, live fire data. When you are using a Ballistic Solver such as the AB Apps or Devices integrated with AB, you need to know the MV to an accuracy down to 5 fps. The more reliable the MV number, the better your ballistics solutions.
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.
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.
You’ll want to read Jason’s full review which shows more before and after images. The full article features a “how-to” video created by Forum member Cory Dickerson, the young man who pioneered the stainless tumbling process and founded STM. The video shows how to load brass, media, and cleaner solutions into the tumbler, and how to separate media from brass once the tumbling is done.
Many of our readers have never had a chance to shoot much past 600 yards. How far away does a 1000-yard+ target really seem to the naked eye? Well this short video answers that question. Gorilla Ammo, the video’s producers, used a camera-carrying aerial drone to fly downrange from the firing line all the way out to 1122 yards (and back again). Watch the drone footage at 0:00-0:07 and especially 0:48-1:03. The “bird’s-eye view” really gives you a sense of the distance. The “fly-back” at 0:48-1:03 time-mark is what makes this video worth watching.
The video features prone shooting at steel targets placed at 750 and 1122 yards. We do apologize for the lame, “oh so serious” voice-over which attempts to make this rather ordinary range session seem like some kind of life-changing experience. (Frankly, you may just want to turn the sound off — it’s that annoying.) It’s really not that big a deal to hit steel at 750 yards with a quality AR-15, chambered in .223 Rem, shooting Sierra 77 grain MatchKings.
Hitting Steel at 1122 Yards with 2540 FPS Ammo Can Be Challenging
The 1122-yard hits are a bit more impressive. Gorilla Ammo lists a relatively sedate 2540 fps Muzzle Velocity for its .223 Rem 77gr SMK ammunition. According to JBM Ballistics, at 1125 yards, that 2540 fps load has 68.3 MOA of drop from a 100-yard zero (firing at sea level and 80° F ambient). Morever the bullet goes trans-sonic around 750 yards (losing stability) and is traveling just 933 fps at impact. And the wind’s the killer — at 1125 yards, with this bullet/load, a mere 2 mph, full-value wind change can move the Point of Impact over three feet!
Vihtavuori has updated and enhanced its reloading information, adding VV powder load recipes for many more cartridge types. Data is now online for 64 rifle cartridge types and 26 pistol cartridge types. You’ll find the updated reloading data on the Vihtavuori Website.

Berger Bullets has released new .30 caliber bullet that could be a game changer for the F-TR discipline — a bullet with exceptional accuracy and very high BC. Berger’s NEW 200.20X Hybrid Target Bullet is the result of extensive research and development in partnership with the U.S. Rifle Team (F-TR), world champion shooters, and accuracy enthusiasts within the long range shooting community.
The new 200.20X has a 0.640 G1/0.328 G7 BC compared to 0.616 G1/0.316 G7 for the older 200 grain .30 caliber Hybrid. That’s a significant reduction in drag. Recommended twist for the new bullet is 1:10″, same as with the earlier 200-grainer.
Berger Chief Ballistician and U.S. Rifle Team (F-TR) member Bryan Litz said, “This is the ideal bullet for F-TR and similar long-range disciplines. The 200.20X has a longer boat tail and nose, with shorter bearing surface which equates to less drag, a higher ballistic coefficient, and fewer points lost to the wind. The BC of the new 200.20X is 4% higher than the existing 200 grain Target Hybrid (G7 BC of 0.328 vs. 0.316). The shorter bearing surface also makes the 200.20X easy to load and shoot in standard chambers. New shooters won’t need special reamers or costly gunsmithing to make this bullet perform.” Bryan himself is switching to the new 200.20X: “After winning the 2015 National Mid-Range and Long Range F-TR Championships with the Berger 215 grain Target Hybrid, I’m switching to the 200.20X because it’s an even better option.”
Bryan tells us that new 200-20X bullet requires a 1:10″ twist to achieve full stability and performance (BC) in most conditions, but you can shoot it out of a 1:11″ twist with a minor decrease in BC. For a stability analysis, enter this bullet in the Berger Stability Calculator with a weight of 200.2 grains, and a length of 1.508″ to get stability results for your particular rifle and atmospheric conditions.
After extensive field testing, this new 200.20X bullet has been adopted as the official .30 caliber match projectile for the U.S. Rifle Team (F-TR). The team verified that this new bullet offers very impressive performance — the higher BC equates to less wind drift, and this bullet has shown exceptional ability to “hold waterline”. Check out this 1000-yard group by Team member Dan Pohlabel, as shown on an electronic target monitor.

Coating bullets with a friction-reducing compound such as Molybdenum Disulfide (Moly) offers potential benefits, including reduced barrel heat, and being able to shoot longer strings of fire between bore cleanings. One of the effects of reduced friction can be the lessening of internal barrel pressures. This, in turn, means that coated bullets may run slower than naked bullets (with charges held equal). To restore velocities, shooters running coated bullets are inclined to “bump up” the load — but you need to be cautious.
Be Careful When Increasing Loads for Coated Bullets
We caution shooters that when your start out with coated bullets in a “fresh barrel” you should NOT immediately raise the charge weight. It may take a couple dozen coated rounds before the anti-friction coating is distributed through the bore, and you really start to see the reduced pressures. Some guys will automatically add a grain or so to recommended “naked” bullet charge weights when they shoot coated bullets. That’s a risky undertaking.
Instead we recommend that you use “naked” bullet loads for the first dozen coated rounds through a new barrel. Use a chronograph and monitor velocities. It may take up to 30 rounds before you see a reduction in velocity of 30-50 fps that indicates that your anti-friction coating is fully effective.
We have a friend who was recently testing moly-coated 6mm bullets in a 6-6.5×47. Moly had not been used in the barrel before. Our friend had added a grain to his “naked” bullet load, thinking that would compensate for the predicted lower pressures. What he found instead was that his loads were WAY too hot initially. It took 30+ moly-coated rounds through the bore before he saw his velocities drop — a sign that the pressure had lowered due to the moly. For the rounds fired before that point his pressures were too high, and he ended up tossing some expensive Lapua brass into the trash because the primer pockets had expanded excessively.
LESSON: Start low, even with coated bullets. Don’t increase your charge weights (over naked bullet loads) until you have clear evidence of lower pressure and reduced velocity.
Procedure After Barrel Cleaning
If you shoot Moly, and clean the barrel aggressively after a match, you may want to shoot a dozen coated “foulers” before starting your record string. Robert Whitley, who has used Moly in some of his rifles, tells us he liked to have 10-15 coated rounds through the bore before commencing record fire. In a “squeaky-clean” bore, you won’t get the full “benefits” of moly immediately.
To learn more about the properties of dry lubricants for bullets, read our Guide to Coating Bullets. This covers the three most popular bullet coatings: Molybdenum Disulfide (Moly), Tungsten Disulfide (WS2 or ‘Danzac’), and Hexagonal Boron Nitride (HBN). The article discusses the pros and cons of the different bullet coatings and offers step-by-step, illustrated instructions on how to coat your bullets using a tumbler.
