Scratches on Bullet Jackets Affect BC and Long Range Accuracy

applied ballistics mobile lab schedule

Here’s a smart tip from Bryan Litz, explaining how damage to a bullet jacket can harm the projectile’s Ballistic Coefficient (BC). This tip is posted on Bryan’s new Bryan Litz Ballistics Facebook page. We recommend you subscribe to that page to access Bryan’s latest informative posts.

Bryan notes: “If the case mouth scratches the bullet when you seat it, the damage can cause the BC to be inconsistent, which shows up as vertical dispersion at long range.”

We see this sometimes when running Doppler Radar for competitors at Applied Ballistics Mobile Lab events. If someone is shooting a bullet that typically has a very consistent BC (1% or less) but they’re seeing a higher BC variation, it can be due to the bullets being damaged in the loading process.”

The lead photo above shows the badly-scratched jacket of a bullet seated in a rough-mouthed case. To prevent such jacket damage, one should chamfer, deburr, and smooth case mouths after trimming.

Below is a recorded Doppler radar result showing excessive BC variation. Such variation can increase vertical dispersion at long range. This can result in larger group sizes and lower scores.

Inspect Your Brass To Detect Case Failure Warning Signs

Glen Zediker reloaders corner midsouth book AR-16 reloading semi-auto brass safety primer resizing
Close-up view of a sectioned case. This one here was “fixin’ to pop”, observed Glen Zediker.

Here are highlights from an article Glen Zediker wrote for the Midsouth Blog. In that article Glen, who sadly passed away in 2020, focused on cartridge brass. Glen identified the most common failures that appear with brass that has been shot multiple times, or which has been fired at excessive pressures. Glen explained some simple ways to check your cartridge brass to detect “early warning signs” of case failure, particularly case head separation, which can be very dangerous.

Glen authored many excellent books on reloading. This article is adapted from two of Glen’s books: Handloading For Competition and Top-Grade Ammo.

How Cases Degrade with Multiple Firings By Glen Zediker
This article explains when, and then how, to check after the progress of changes commencing with the firing on a new case. It’s the “progress of degeneration,” in a way of looking at it because the concern is getting a handle on when enough change in the brass has come about to require attention. Or abandonment. As said then, for me that’s 4 firings. That, as said last time, is when I might see changes that need attention. Also as said, that figure didn’t come out of a hat, but from my own notes in running my competition NRA High Power Rifle loads. [Editor’s Note: With Lapua brass, using moderate loads, in bolt-action rifles, we typically get about 10 good (match-worthy) firings. But if you anneal your Lapua brass, and run modest pressures, Lapua brass can perform well for 20 or more load cycles.]

The areas most affected are the case neck and case head area. Case neck walls get thicker [but] the case head area body walls get thinner. Primer pockets get shallower and larger diameter.

Glen Zediker reloaders corner midsouth book AR-16 reloading semi-auto brass safety primer resizing

This case shows a cracked neck AND a crack (separation) above the case head. Zediker says it is “rare to see one case with both of the most common failures. [This case] was attacked by an M14.”

Case Head — Causes of Separation and Cracking
When a case is under pressure during firing, the brass, like water, flows where it can, where it’s more free to move. Of course, the chamber steel limits the amount it can expand. The case shoulder blows fully forward and the case base is slammed back against the bolt face. There is, therefore and in effect, a tug on both ends — it gets stretched. The shoulder area is relatively free to expand to conform to the chamber, but the other end, the case head area, is not. Since that’s the area of the case with the thickest walls, it doesn’t expand “out” much at all. What it does is stretch. The “case head area,” as I refer to it here, is the portion of the case above the web, which is just above the taper that leads in to the extractor groove. The “area” extends approximately an eighth-inch up the case body.

Glen Zediker reloaders corner midsouth book AR-16 reloading semi-auto brass safety primer resizing

Here’s a “pressure ring.” You’ll see this after firing, if you see it. And, if you see it, that case is done. The bright ring indicates excessive stretching, which indicates excessive thinning. If you see a ring circling the case, noticeable because it’s lighter color than the case body, and it’s in this area, I’d say that case is done. And that’s right where a “head separation” occurs. It can crack and also blow slap in two, and that’s the “separation” part of case head separation.

This is a spot to keep close watch on as cases age. It is also the area that is more “protected” by sizing with less case shoulder set-back. That is, pretty much, where the freedom for the stretching movement in this area comes from (the case shoulder creates a gap). If you’re seeing a sign that a head separation [might happen with relatively few firings], chances are the shoulder set-back is excessive, and also… the load pressure level.

Bent Paper Clip Case-Wall Gauge
Case-Head Separation paper clip Glen Zediker GS Arizona

Editor: You can use a bent paper clip to detect potential case wall problems. Slide the paper clip inside your case to check for thin spots. GS Arizona explains: “This simple little tool (bent paper clip) will let you check the inside of cases before you reload them. The thin spot will be immediately apparent as you run the clip up the inside of the case. If you’re seeing a shiny line on the outside and the clip is really hitting a thin spot inside, it’s time to retire the case.” Photo by GS Arizona.

Monitor Primer Pocket Dimensional Changes
Another case-head-area and pressure-related check is the primer pocket. As said, the primer pocket will get larger in diameter and shallower in depth each firing. As with many such things, the questions are “when” and “how much,” and the main thing, “how much?”

If the pocket gets excessively shallow, and that’s judged by a primer that seats fully but isn’t at least a tick below flush with the case base, there could be function issues. There’s a risk of a “slam-fire” with a semi-auto that uses a floating firing pin, and, if there is actual protrusion, that has the same effect as insufficient headspace. A primer pocket uniformer can reset the depth of a shallowed primer pocket to what it should be, but the real test for me is how easily the next primer seats into it. If it’s significantly less resistance, I’ll say that case is done. Shallower can be refurbished. That’s a primary function of a primer pocket uniformer. Larger diameter, though, can’t be fixed. I’ve mentioned in another article or two that, any more at least, my main gauge of load pressure has become how much primer pocket expansion there’s been.

How to Select and Set Up Decapping Dies Properly

universal Decapping die sinclair lee redding

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.

Universal decapping die

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 Costs Just $11.49
Speaking of decapping tools, Midsouth Shooters Supply sells the LEE Universal Decapping Die for just $11.49 (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.

Lee universal decapping die

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 $46.99 die ships with three decapping 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:

Wrong Cartridge in Chamber — What Can Happen

Ruptured Cartridge Case

If you don’t match your ammo to your chamber, bad things can happen, that’s for sure. A while back, Forum member BigBlack had an experience at the gun range that reminds us of the importance of safety when shooting. He encountered evidence that someone had fired the wrong cartridge in a 7mm WSM rifle. The problem is more common than you may think. This Editor has personally seen novices try to shoot 9mm ammo in 40 S&W pistols. BigBlack’s story is along those lines, though the results were much more dramatic. It’s too bad a knowledgeable shooter was not nearby to “intervene” before this fellow chambered the wrong ammo.

7mm-08 is Not the Same as a 7mm WSM
BigBlack writes: “I know this has probably been replayed a thousand times but I feel we can never be reminded enough about safety. This weekend at the range I found a ruptured case on the ground. My immediate thoughts were that it was a hot load, but the neck area was begging for me to take a closer look, so I did. I took home the exploded case and rummaged through my old cases until I found a close match. From my investigative work it appears someone shot a 7mm-08 in a 7mm WSM. Take a look. In the above photo I’ve put together a 7mm WSM case (top), the ruptured case (middle), and a 7mm-08 case (bottom).”

The photo reveals what probably happened to the 7mm-08 case. The shoulder moved forward to match the 7mm WSM profile. The sidewalls of the case expanded outward in the much larger 7mm WSM chamber until they lacked the strength to contain the charge, and then the case sides ruptured catastrophically. A blow-out of this kind can be very dangerous, as the expanding gasses may not be completely contained within the action.

Can’t Happen to You? Think Again.
This kind of mistake — chambering the wrong cartridge — can happen to any shooter who is distracted, who places even a single wrong round in an ammo box, or who has two types of ammo on the bench. One of our Forum members was testing two different rifles recently and he picked up the wrong cartridge from the bench. As a result, he fired a .30-06 round in a .300 Win Mag chamber, and the case blew out. Here is his story:

“I took two of my hunting rifles I have not used for over 25 years to the range yesterday to get new scopes on paper, a .30-06 and .300 Win Mag. I had four boxes of old Winchester factory ammo (two of each cartridge), which had near identical appearances. I accidentally chambered a .30-06 round in the Sako .300 Win Mag rifle. It sprayed powder on my face and cracked the stock at the pistol grip. If I had not been wearing safety glasses I might be blind right now.

Safety eyewear glasses
You should always wear protective eyewear, EVERY time you shoot.

“I feel lucky and am very thankful for being OK — other than my face looks funny right now. I am also grateful for learning a valuable lesson. I will never put two different cartridges on the bench at the same time again.”

“How Do Bullets Fly” — Great Online Resource with Smart Science

Bullet External Ballistics
“The overturning moment MW tends to rotate the bullet about an axis, which goes through the CG (center of gravity) and which is perpendicular to the plane of drag….

Ruprecht Nennstiel, a forensic ballistics expert from Wiesbaden, Germany, has authored a great resource about bullet behavior in flight. Nennstiel’s comprehensive article, How Do Bullets Fly, explains all the forces which affect bullet flight including gravity, wind, gyroscopic effects, aerodynamic drag, and lift. Nennstiel even explains the rather arcane Magnus Force and Coriolis Effect which come into play at long ranges. Nennstiel’s remarkable resource contains many useful illustrations plus new experimental observations of bullets fired from small arms, both at short and at long ranges.

Shadowgraph of .308 Winchester Bullet

Bullet External Ballistics

A convenient index is provided so you can study each particular force in sequence. Writing with clear, precise prose, Nennstiel explains each key factor that affects external ballistics. For starters, we all know that bullets spin when launched from a rifled barrel. But Nennstiel explains in greater detail how this spinning creates gyroscopic stability:

“The overturning moment MW tends to rotate the bullet about an axis, which goes through the CG (center of gravity) and which is perpendicular to the plane of drag, the plane, formed by the velocity vector ‘v’ and the longitudinal axis of the bullet. In the absence of spin, the yaw angle ‘δ’ would grow and the bullet would tumble.

If the bullet has sufficient spin, saying if it rotates fast enough about its axis of form, the gyroscopic effect takes place: the bullet’s longitudinal axis moves into the direction of the overturning moment, perpendicular to the plane of drag. This axis shift however alters the plane of drag, which then rotates about the velocity vector. This movement is called precession or slow mode oscillation.”

Raise Your Ballistic IQ
Though comprehensible to the average reader with some grounding in basic physics, Nennstiel’s work is really the equivalent of a Ph.D thesis in external ballistics. You could easily spend hours reading (and re-reading) all the primary material as well as the detailed FAQ section. But we think it’s worth plowing into How Do Bullets Fly from start to finish. We suggest you bookmark the page for future reference. You can also download the complete article for future reference and offline reading.

GREAT Video on Making Brass and Precision Ammo — Watch Now

Norma factory ammo production video

Guys — honestly, if you do anything today on this site, watch this video. You won’t be disappointed. Guaranteed. This is a very informative (and surprisingly entertaining) video. Every serious hand-loader should watch this video to see how cartridge cases and loaded ammo are made. Your Editor has watched the video multiple times and I still find it fascinating. The camera work and editing are excellent — there are many close-ups revealing key processes such as annealing and head-stamping.

VERY Informative Video Show Cartridge Brass and Ammunition Production:

Norma has released a fascinating video showing how bullet, brass, and ammunition are produced at the Norma Precision AB factory which first opened in 1902. You can see how cartridges are made starting with brass disks, then formed into shape through a series of processes, including “hitting [the cup] with a 30-ton hammer”. After annealing (shown at 0:08″), samples from every batch of brass are analyzed (at multiple points along the case length) to check metal grain structure and hardness. Before packing, each case is visually inspected by a human being (3:27″ time-mark).

The video also shows how bullets are made from jackets and lead cores. Finally, you can watch the loading machines that fill cases with powder, seat the bullets, and then transport the loaded rounds to the packing system. In his enthusiasm, the reporter/narrator does sometimes confuse the term “bullets” and “rounds” (5:00″), but you can figure out what he means. We definitely recommend watching this video. It’s fascinating to see 110-year-old sorting devices on the assembly line right next to state-of-the art, digitally-controlled production machinery.

Sunday GunDay: Weatherby Mark V Backcountry 2.0 Ultralights

Weatherby backcountry 2.0 Mark V ti titanium carbon stock ultralight

Hunting season is here. Around the country, game hunters are getting prepared for fall deer hunts. For hunters making long treks in the back-country, reducing carry weight is a big deal. That’s why we’ve seen a trend among rifle-makers to introduce rifles that weigh significantly less. This is accomplished through use of carbon fiber stocks, carbon-wrapped or fluted barrels, and even titanium actions. Today’s showcased Weatherby rifles feature these lightweight components. As a result, the Weatherby Backcountry 2.0 Ti (Titanium) model comes in at just 4.7 pounds before optics. That’s mighty light for a hunting rifle.

Light-Weight, Carbon-Stock Backcountry 2.0 from Weatherby

Here is good news for backcountry hunters. Weatherby’s Backcountry 2.0 carbon-stocked hunting rifles weigh well under 6 pounds before optics. There is even one titanium action model series that weighs just 4.7 pounds. The 2.0 series now offers both standard steel receivers or even lighter titanium receivers. And Backcountry 2.0 Carbon models are equipped with a new carbon fiber stock that is the lightest in the industry — weight is a mere 20 ounces for standard actions. For further weight savings, some models feature a tensioned carbon fiber-wrapped barrel. But all that high-tech doesn’t come cheap — MSRP for the Titanium action, carbon-wrapped barrel model is $3849.00!

Ultralight Carbon Stock — Weatherby’s new Blacktooth stock features a Carbon Link™ bedding system which engages the recoil lug and distributes recoil throughout the stock without the weight of a traditional aluminum bedding block. This makes the overall stock lighter and stiffer.

The Backcountry 2.0 Ti Carbon combines a tensioned carbon fiber barrel with the ultra-lightweight Titanium Weatherby Mark V action. This barrel system has shown excellent accuracy, making it a good choice for a long-range hunter. Registering a very low 5.3 lb starting weight, the Backcountry 2.0 Ti Carbon combines a titanium action with the Peak 44 Blacktooth stock — which Weatherby claims is the “lightest production carbon fiber stock on the market.”

Along with the new ultra-light elements, these Weatherbys have premium Mark V features: 54-degree bolt lift for fast cycling, fluted bolts, TriggerTech triggers, and Cerakote finish on metal parts. All the Backcountry 2.0 series rifles have a sub-MOA accuracy guarantee. CLICK HERE for Weatherby Backcountry 2.0 Field Test by Peterson’s Hunting.

Light is Right — Weatherby’s Backcountry 2.0 rifles weigh as little as 4.7 pounds (before optics).

Weights for Backcountry 2.0 Models range with chamberings:

Backcountry 2.0 – 5.3 lbs (.308 Win) to 6.2 lbs (.257 WBY MAG) (MSRP $2499.00)
Backcountry 2.0 Ti – 4.7 lbs (.308 Win) to 5.6 lbs (.257 WBY MAG) (MSRP $3449.00)
Backcountry 2.0 Carbon – 5.8 lbs (6.5 Creedmoor) to 6.6 lbs (.257 WBY MAG) (MSRP $3299.00)
Backcountry 2.0 Ti Carbon – 5.3 lbs (6.5 Creedmoor) to 6.6 lbs (.257 WBY MAG) (MSRP $3849.00)

Weight Saving Secrets — How Weatherby Achieved Such Light Weights
GunsAmerica Digest reports: “A huge amount of the weight savings comes thanks to the updated carbon fiber Blacktooth stock by Peak 44. This stock uses what they call their Rock Solid Carbon Link bedding system which eliminates the need for a metallic bedding block. The Blacktooth stock weighs less than 20 ounces. The Backcountry 2.0 [series adds] both a carbon fiber stock and either fluted #1 MOD-profile or #2 MOD-profile carbon steel barrels or #4 MOD-profile BSF carbon fiber-tensioned barrel to achieve these light weights.” READ GunsAmerica Review.

To mitigate recoil Weatherby developed its new 3DHEX recoil pad — the gun industry’s first production 3D-printed pad. The 3DHEX’s three-dimensional honeycombed design extends the duration of the recoil pulse — taking away the sharp kick. Weatherby explains: “With the same amount of recoil spread out over a much greater time period, felt recoil is greatly reduced[.]” Backcountry 2.0 rifle recoil is also reduced by factory-fitted Accubrakes, contoured to match barrel profile.

Field Test of Titanium Action Weatherby Backcountry in 6.5-300 Whby Magnum
In this video, Hunter Todd Helms reviews Weatherby’s Backcountry T1 rifle in 6.5-300 Weatherby Magnum. This rifle is meant for fast and light travel in the backcountry. A fluted barrel, titanium action, and carbon fiber stock minimize weight. Todd says the 3DHEX recoil pad really does tame the magnum kick. This model also features a new streamlined muzzle brake.

Preparations Before The Hunt

1. Map Your Hunt and Notify Others — Before your hunt, make a plan and notify friends and family members about WHERE you are going and your intended return date and time. Print out a Google Satellite map and locate landmarks and trailheads. Mark where you plan to park your vehicle and give a copy of this map to friend and/or family members. A hunter may injure himself by falling off a rock, or tumbling in a creek-bed. After that kind of injury the hunter may be confused or unable to walk. If you get stranded in the wilderness, you want trusted persons to know where you are. So, before you leave on a trip, provide a map to a friend or family member. Show them where you will leave your vehicle, and where you expect to be every day of your hunting adventure.

2. Licenses and Permits — Make sure you have a valid hunting licenses and all the necessary tags. Begin this process with ample time before your intended hunt(s). The NSSF adds: “If you are crossing state or national borders, find out about any special considerations you must take care of. Border crossings can mean knowing about firearm transport laws or Chronic Wasting Disease-related regulations.”

3. Work on Your Fitness — On a multi-day hunt you may be trekking many miles. You need to be in good shape. If you are out of shape you may be putting yourself in a precarious situation, particularly if you underestimate the terrain difficulty. As the NSSF says: “Not being able to handle the conditions lessens your chances of success, can turn a great experience into an agonizing one and can endanger your health.”

4. Do Your Homework — Study the area you will be hunting. Talk to other hunters. Look at satellite photos. Get a real sense of the walking and terrain challenges. For a multi-day hunt, MAKE a PLAN. The NSSF states: “Eliminate surprises. Learn as much about where you will be staying, the area you will be hunting, what the weather might be like and what you need to bring[.]”

5. Rifle and Ammo — Make sure your rifle is sighted-in and your ammo is tested. Sight-in your rifle with the ammo you plan to use on your hunt. CLICK HERE for 4-Shot Sight-in Method. After sighting-in from the bench, confirm your zero by shooting from typical hunting positions (kneeling and with forearm supported on a rock or post).

6. Communications and GPS — Bring a GPS if you are in a wilderness area far from civilization. It’s a good idea to bring a cell phone, but you may not have coverage if you’re quite a distance from populated areas. A smart-phone also doubles as a digital camera to record your trophies. For navigation and safety, consider getting Garmin inReach Explorer+. This high-tech handheld unit features interactive SOS, connecting you to the GEOS 24/7 search-and-rescue monitoring center. They also allow you to send and receive text messages, no matter where you are, via advanced inReach satellite technology. Yes you can communicate even if you are miles from the nearest cell tower.

Visit WhereToHunt.org
