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.

If two barrels are better than one, then why not three? That’s the thinking behind the exotic Bockdriling BD14 from Blaser, unveiled at the 2014 IWA Show in Germany. This three-barrel Bockdrilling firearm works as a shotgun, large-caliber rifle, and small-caliber rifle all in one. Even with all those barrels, the BD14 is relatively light, at 3.3 kg (7.26 lbs) without optics. That makes this a nice, carry-around gun for stalking. As you’d expect from Blaser, the twin triggers are crisp and precise, with a pull weight of just 1.43 lbs (650 grams). The front trigger is for the large-caliber rifle barrel, while the rear trigger works both the shotgun and small-caliber barrels, via a tang-mounted selector. These firearms are rare in the USA — and quite expensive. The only Blaser BD 14 we could find on GunBroker had a $9099.95 asking price. That works out to over three grand per barrel.
Here’s what Blaser USA has to say about its unique three-barreled BD 14:
“The ‘Bockdrilling’ is, put simply, an over/under (O/U) rifle-shotgun combination with a smaller caliber rifle-barrel… on the side. The barrel arrangement [allows] for an extremely slender receiver, making the BD14 exceptionally huntable.
The [patent-pending] Vertical Block Lockup… combines an extremely compact and solid block lockup in a closed system within the monoblock with the comfortable handling of a classic break-action rifle.
The double lock permits, if needed, a rapid second shot, the front trigger always releasing the large rifle-caliber. The … barrel selector actives the shotgun barrel when in position ‘top’ and activates the smaller rifle caliber in position ‘bottom’.”
Why Does Anyone Need Three Barrels?
The Blaser website explains: “As hunters, we learn to expect the unexpected, whether in a blind or stalking, so it’s understandable that we dream of a firearm that will allow us to take advantage of any situation. With the Bockdrilling BD14, Blaser has developed the perfect blind and stalking firearm – compromises are finally a thing of the past.”
Design Features of the Bockdrilling BD 14 Tri-Barrel Gun
The BD14 has a double-lock system so that a second shot can be taken without having to recock the firearm. Blaser says: “Thanks to the free-floating barrels, point of impact remains constant even with a quick succession of shots, no matter which barrel was fired first. The extremely strong vertical block lock on the BD14 helps contribute to the high degree of precision.”

Hunting season is coming soon in most parts of the country. As part of NRA Women TV, hunting guide Kristy Titus hosts a series of videos that explain important strategies and shooting skills for hunters. These videos can help you prepare for a fall hunt. Titus is a certified instructor who has hunted around the globe. She grew up in the outdoors, running pack mules in Oregon with her father. In these videos, Kristy discusses demonstrates field positions that can be employed during a hunt. She also explains preparation for a hunt, including fitness training.

Kristy says: “When it comes to bolt-action rifle fit, there is no ‘one size fits all’. When picking out your rifle [consider options] after the purchase to ensure you are as comfortable as possible.”
We are seeing decent prices on name-brand factory-loaded ammo, and there are some notable inventories of ammunition right now at Midsouth, Palmetto State Armory, Powder Valley, and Precision Reloading. We are even starting to see ample supplies of large-caliber hunting rifle ammunition — something hard to find a couple seasons back.
Thankfully, if you shop around aggressively, you can now find many types of ammunition at reasonable prices. By using AmmoSeek.com you can instantly compare ammo prices from dozens of sellers. AmmoSeek monitors more than 180 online vendors — checking current pricing and available inventory, for pistol, rifle, and shotgun ammunition.

AmmoSeek.com FAQ Page
If you have questions about using AmmoSeek.com, visit the AmmoSeek FAQ Page. You’ll find details on how the search engine works. Here’s one FAQ:
How often does the AmmoSeek engine process its ammunition data?
Every minute or two! AmmoSeek is constantly updating ammunition data 24 hours a day, 7 days a week, automatically. Individual retailers are updated at least hourly, most most are updated much more often. Still, however, there’s always the possibility that items can go out of stock the moment after our site is updated, so it’s not always possible to be 100% accurate.
Hunting season is underway now in many states. That means it’s time to inspect all your hunting gear, including your scope set-up. If you have a new optic, you’ll want to get it mounted correctly on your current rig. And if you have a new hunting rifle, you’ll need to mount the properly rings and install the riflescope so that you have the correct eye relief.
A proper scope installation involves more than just tensioning a set of rings — you need to consider the proper eye relief and head position, and it should be leveled correctly. This video shows a simple, quick method to mount a scope. The method assumes that the reticle (cross-hairs) are square without the turret. You’ll want to confirm that with a plumb line hanging straight down, a procedure you can do indoors.
In this NSSF video, Ryan Cleckner shows how to set up a scope on a hunting or tactical rifle. Ryan, a former U.S. Army Sniper Instructor, notes that many hunters spend a small fortune on equipment, but fail to set up their rifle to use the optics optimally. Cleckner likens this to someone who owns an expensive sports car, but never adjusts the seat or the mirrors.
Ryan notes that you want your head and neck to be able to rest naturally on the stock, without straining. You head should rest comfortably on the stock. If you have to consciously lift your head off the stock to see through the scope, then your set-up isn’t correct. Likewise, You shouldn’t have to push your head forward or pull it back to see a clear image through the scope. If you need to strain forward or pull back to get correct eye relief, then the scope’s fore/aft position in the rings needs to be altered. Watch the full video for more tips.
Tips on Mounting Your Scope and Adjusting Your Comb Height:
1. Normally, you want your scope mounted as low as possible, while allowing sufficient clearance for the front objective. (NOTE: Benchrest shooters may prefer a high mount for a variety of reasons.)
2. Once the scope height is set, you need to get your head to the correct level. This may require adding an accessory cheekpad, or raising the comb height if your rifle has an adjustable cheekpiece.
3. Start with the rifle in the position you use most often (standing, kneeling, or prone). If you shoot mostly prone, you need to get down on the ground. Close your eyes, and let you head rest naturally on the stock. Then open your eyes, and see if you are too low or too high. You may need to use a cheekpad to get your head higher on the stock.
4. If your scope has a flat on the bottom of the turret housing, this will help you level your scope. Just find a flat piece of metal that slides easily between the bottom of the scope and the rail. Slide that metal piece under the scope and then tilt it up so the flat on the bottom of the scope aligns parallel with the flats on the rail. Watch the video at 8:40 to see how this is done.

When shooting groups at long range on paper it can be difficult to distinguish which bullet holes belong to a particular sequence of shots. If, for example, you shot three 5-shot groups at 600+ yards on a paper target, you would have 15 bullet holes on the target (assuming no misses). But at that distance it would be difficult to see the holes on target (even with a spotting scope). Accordingly, when you inspected the target up close, it would be hard to tell which shots belonged to which group. You might have a vague idea, but couldn’t be sure, without a target camera recording the shot sequence.
Here is a method to separate multiple shots into specific groups so you can better evaluate your load and shooting skills. The trick is pretty simple — mark your bullets with a color from a Sharpie or other felt marking pen. If you are shooting three 5-shot groups, mark five with red, five with green, and five with blue (or purple). Then, when you inspect the target, you can identify the group placements by the colors that appear on the paper.
Round Robin: Using colors you can shoot “Round-Robin” to evaluate seating depths, neck tension, or other variables without having the shot order (and barrel heating) affect group sizes unequally. For example you might have three different neck tensions, each marked with a different color on the bullets. Then shoot Red, Blue, Green in that sequence for five total shots per color.
Smart Tip to Show Colors More Vividly
If the bullet inks are not showing up on your target paper clearly, here is a simple trick that can make the colors “bleed” to be more visible. In your range kit, bring some alcohol solution along with some Q-tips. Then dab the shots on the paper target lightly with wet Q-Tips. Here is the front of a target before and after application of alcohol:
Forum Member NewbieShooter explains: “Dabbing a bit of alcohol on the bullet holes with Q-Tips makes the color pop a bit… especially on the back side.” See below:
In short order you will see the colors spread into the paper, clearly marking the shot holes by distinguishing colors. If you were shooting a dark bullseye, view the the BACK side of the target to see the colors on a light background.
