This can be very important — even life-saving. For example, with a hang fire, i.e. a round that does not fire immediately, it is vital to keep the gun pointed DOWN-RANGE. And with a squib load, which may have left a round inside the barrel, it is vital to UNLOAD and NOT take another shot! If you did, the gun could blow up in your hand when the second, full-charge bullet hits the trapped bullet.
The Five Topics Covered Are:
Misfeed (aka Tip-Up)
Double Feed
Stovepipe (Failure to Extract)
Misfire / Hangfire
Squib Load
1. Misfeed or Tip-Up: With any misfeed you should stop firing. With the muzzle pointed safely down-range, remove the magazine, then pull the slide back and remove the round that did not feed. Check the slide for dirt, debris, and check the round that did not feed. After re-inserting the magazine, make sure the mag is seated properly.
2. Double-Feed: This is a fairly common issue with some gun types with worn springs or cheap magazines. Again you want to remove the magazine. CTD states: “Remove the magazine and cycle the action until your double-fed rounds fall out — always keeping the muzzle pointed in a safe direction[.]”
3. Stove-Pipe: This occurs when the case of a fired round does not eject fully. There can be many causes — damaged extractor, low-pressure powder charge, dirty chamber, or greasy cartridge brass. In addition the issue is common with old, worn-out recoil springs. To avoid Stove-Pipes, replace the recoil spring every 4000 rounds, and make sure your chamber is clean and the extractor is not chipped or damaged.
4. Misfires and Hang-Fires: There are multiple causes for misfires (“click no bang”) and hang-fires (slow ignition). There can be a defective primer, the firing pin could be damaged, the powder many have been bad, or the case not filled properly. With a misfire, keep the gun pointed down-range at least one minute. If the case does not fire, eject it but leave it on the ground. With a hang-fire (delayed ignition after firing pin strike), keep the gun pointed down-range, then drop the magazine and eject the (new) unfired cartridge in the chamber and inspect the gun when completely empty.
5. Squib Load: A squib load is when the gun fires, but the actual case ignition is very light with little noise, smoke, or recoil. This can be because the case had a primer but no powder. Or it can be because the powder did not ignite. Squib loads can be very dangerous in rapid-fire situations. If you EVER get a squib load STOP immediately! Do NOT fire another round! This is because the squib may have left a bullet inside the barrel.

A while back, the Precision Rifle Blog conducted a fascinating study of Muzzle Brakes. PRB figured out a way to show the actual “blast pattern” of gasses ejecting from the ports of muzzle brakes. The result was a fascinating (and eye-catching) series of images revealing the distinctive gas outflows of 20+ different types of muzzle brakes. If you are considering buying and installing a muzzle brake on your rifle, you should definitely review this important PRB Muzzle Brake Test.
For a prone shooter, particularly on dusty, dirty or sandy ground, muzzle blast is a major bummer. Muzzle blast can be very disturbing — not just for the trigger-puller but for persons on either side of the gun as well. Some muzzle brakes send a huge shockwave back towards the shooter, and others send blast towards the ground, kicking dirt and debris into the prone shooter’s face. If there was a way to illustrate those factors — shockwave and debris — that might help shooters select one brake design over another.
Cal Zant at PrecisionRifleBlog.com applied a unique blend of creativity and resourcefulness to try to answer that question for 20+ muzzle brakes. Using high-speed photography and household products, he captured the blast pattern of 20+ different brake designs for easy side-by-side comparison. Can you figure out how Cal managed to show muzzle brake blasts so clearly? His “hi-viz” solution, revealed in the article, is very clever. See the eye-opening results for 20+ brakes, with illustrative photos, by visiting the Precision Rifle Blog Muzzle Brake Ground Signature Test Page.

Hunting season is coming soon. For hunters that means many hours may be spent searching for animals through spotting scopes and binoculars — “glassing” for game. And when the hunter does find a good buck or doe, he’ll need to know the animal’s precise distance, so that demands a good laser rangefinder. Being carried in the field, the scopes on hunting rifles need to be tough and durable, and every hunting scope should have excellent low-light performance. And when the hunter finally takes his shot, his scope better be properly zeroed. Today’s Saturday showcase spotlights Hunting Optics. We offer eight great videos that help you select the right riflescope, spotting scope, rangefinder, and binoculars for your next hunt.
Here’s a good video by an avid hunter who treks in remote, mountainous zones. The host has learned what works… and what’s worth the weight to carry: “I’ve found that the combination of 10×42 binoculars and a 27–60x80mm spotting scope is the sweet spot for mountain hunting. This pairing balances weight with reach, allowing me to keep moving but also reach out and see well-hidden animals. In some cases, I will make use of an 18×56 binocular, but this is reserved for non-backpack hunts. With 25 years of mountain hunting experience, I can whole-heartedly recommend my preferred binocular pair as a fantastic and versatile set-up for northern mountain hunts at the very least.”
Ultimate Spotter Test — 19 Spotting Scopes Reviewed
The producers of this remarkable 19-product spotting scope comparison state: “If you are looking at choosing the best spotting scope for hunting… you are in the right place! We tested these 19 spotting scopes to find the best compact spotting scope, best 65mm spotting scope, and best 85mm spotting scope out there. We also wanted to find the best values on the market, and I think we definitely did that. While we certainly couldn’t test them ALL, we were able to put together this incredible lineup of some of the best spotting scopes out there to help you find what is going to work for your specific needs.”
First Focal Plane vs. Second Focal Plane Scopes
For the last century, Second Focal Plane (SFP) scopes have been most common on hunting rifles. Now there are an increasing number of First Focal Plane (FFP) optics favored by hunters. The main reason is that the reticle mark values (in Mils or MOA) are constant relative to the target size at all magnification levels. That is handy for hold-offs and hold-overs. On the other hand, a SFP scope maintains a constant reticle size and line thickness at all zoom values. For most hunting shots, taken inside 300 yards, that really should be fine. Many hunters feel they can spot their prey more easily without a busy reticle that obscures small details at higher magnification. This video explains the pros and cons of both reticle types. The final decision is up to you — much will depend on the terrain you hunt and the distances you shoot.
The Complete Optics Selection for For Deer Hunting
In this video, Vortex optics techs explain the optics package deer hunters will want to take into the field. Along with a good medium-power zoom riflescope, you’ll want binoculars and (probably) a spotting scope. You’ll also want a Laser Rangefinder (LRF) or laser-equipped binoculars. As the team points out, the LRF is not just to range your prey right before you take a shot. A top-quality LRF can range a reflective object as far as 1500 yards away. That helps you decide whether you want to hike a mile to reach that buck you see way out on the next ridge.
MOA vs. MIL — What You Need to Know
These days, scope manufacturers offer a wide selection of both MIL (Milliradian) and MOA (Minute-of-Angle) based optics. We do think that MOA is still predominant in the lighter-weight, lower-cost (sub-$500) scopes marketed for hunters. There are pros and cons for both angular measurement systems. One MIL is 3.6″ at 100 yards, while one MOA is 1.047″ at 100 yards. If you grew up thinking in inches, a 1/4-MOA click-value hunting scope might work best. If you shoot PRS or have other MIL scopes you may prefer a MIL-value optic for your hunting rifle. Both choices will do the job.
Comparison of Eight Laser Rangefinders
The Backfire team purchased eight rangefinders and tested them in the field. Most of the products are under $500. This is a good review if you are looking for a compact LRF at a moderate price. Looking at performance for the price, for the hunting market, the reviewers favored the Leupold RX-1600 and the waterproof Vortex Ranger 1800. COMMENTARY: If you can afford it, we recommend that serious hunters consider top-end laser rangefinder-equipped binoculars such as the ZEISS Victory RF and Leica Geovid.
How to Zero Your Hunting Rifle Efficiently
Last but not least, here’s a great video from Vortex that shows you how to quickly and efficiently sight-in and zero your hunting rifle before heading out into the field. This video explains a simple procedure that lets you get a solid zero in just three shots. Of course you probably want to fire a few more rounds to confirm your zero before you head off to your hunting grounds, but this will let you get on-target with a minimum amount of time and ammo expended. This helpful video has over 3 million views on YouTube!
Fouling Shots and Cold Bore Condition
If you recently cleaned your rifle, you may want to fire two or three fouling shots before you start this procedure. But keep in mind that you want to duplicate the typical cold bore conditions that you’ll experience during the hunt. If you set your zero after three fouling shots, then make sure the bore is in a similar condition when you actually go out hunting.

F-Class ace Erik Cortina has interviewed noted author and Olympic Gold Medal-winning shooter Lanny Bassham. For his popular video channel, Cortina asked Lanny about his book With Winning in Mind. The two talented shooters also broadly discussed the “mental game” in the shooting sports and Lanny’s program for visualization of a winning performance. Lanny explains that after you have mastered your rifle skills, and learned to read the wind, it is important to adopt a winning mentality and to visualize success. Lanny should know. He won a shooting Gold Medal in the Olympics along with 22 world individual and team titles.
Watch Full Video Interview
Here is the wide-ranging and fascinating hour-long Lanny Bassham interview hosted by Erik Cortina. If you are looking to enhance your motivation, discipline, and “mental focus” when competing, this video is worth watching:
Visualization is a process of mental preparation that is done before you get to the range. Many of the greatest shooting champions have used this technique to get ready for big matches, and to optimize their performance during record fire. If you want to enhance your “mental game” through pre-match visualization, we strongly recommend Lanny Bassham’s book, With Winning in Mind.
As a competitive smallbore 3P shooter, Bassham developed a mental management system. Using this system, Lanny Bassham won 22 world individual and team titles, set four world records, and captured an Olympic Gold Medal in Montreal in 1976. His techniques have been embraced by professional and Olympic athletes in many sports. With Winning in Mind covers a complete system of “mental management” techniques used by Olympians and elite champions.
Putting principles into practice — Anette Wachter
Our friend Anette Wachter, aka “30CalGal”, did a series of videos for the NRAWomen.com site. In one episode, Anette talks about the “mental game” in competition. Specifically she explains how to “visualize success”:
I have found that a lot of my success in competition has come through what I call a ‘mental rehearsal’. I actually visualize every stage of the match and I visualize the success of the match and winning the match.
I actually visualize that round going downrange into the target, and the target coming up with a dead-center ‘X’. I visualize this over and over. If you visualize success you will achieve success.

Are sound suppressors useful in competition shooting? In some disciplines, and in venues where sound “moderators” are permitted, the answer is “yes”. In a past edition of Shooting Sports USA eZine, you’ll find an interesting article about the use of sound suppressors (aka “cans”). The article explores the use of suppressors in Europe and in tactical matches in North America. You’ll also find an explanation of the rules and regulations governing suppressor ownership and use in the United States.
Shooting Sports Editor Chip Lohman tests three rifles from the bench and found that sound suppressors did not harm accuracy. In fact, all three test rifles (one each in .223 Rem, .308 Win, and .338 Lapua Magnum), shot slightly better 5-shot groups at 200 yards when a suppressor was fitted to the barrel. However, the suppressors did alter point of impact. Interestingly, velocity standard deviation (SD) values were lower with suppressors in place for all three test rifles. This observation calls for further study.*
So the use of suppressors in competition could be a good thing. However, in the United States, current NRA rules prohibit the use of sound suppressors. NRA Rule 3.16.1 subsection (a) states: “Sound Suppressors are not authorized for use in High Power competition.” In addition, there are some practical problems with suppressors — the heat rising off of a naked suppressor can create mirage problems (that’s why some shooters wrap their cans with a cover).
Despite such issues, now commonly see suppressors on rifles used in tactical matches and PRS/NRL events. For example, many competitors in the Steel Safari field challenge match use suppressors. The photo below shows our friend Zak Smith competing in the Steel Safari with his suppressed Accuracy International rifle.
Commentary — What Can We Conclude?
Obviously, this three-rifle SSUSA test was not definitive. One well might observe different results with different types of suppressors, fitted to different kinds of rifles. Mounting a suppressor to any barrel will certainly affect harmonics and “tune”. But this SSUSA study does suggest that tactical shooters, who are allowed to use suppressors in competition, may find that the benefits of suppressors (significantly reduced recoil and less noise) outweigh any meaningful accuracy loss, at least in PRS-type matches.
NOTE: The article cautions that one should not extrapolate too much from the SD numbers, given the low number of test shots. Chronograph-maker Ken Oehler, when asked to comment on the SD values stated: “[You should] report the observed SDs, but draw no conclusions until… you can do more testing with larger sample sizes.”
Qualifications to Obtain a Suppressor
To legally obtain a suppressor, you must fill out Federal Forms and pay a $200 fee to the ATF. You must also pass BATFE background checks and otherwise comply with Federal and state laws. States can regulate suppressor ownership or use, so be sure to check the laws in your area. On the federal level, the process to acquire a suppressor is regulated under the National Firearms Act of 1934.
“Freedom is never more than one generation away from extinction. We didn’t pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children’s children what it was once like in the United States where men were free.” — Ronald Reagan
Today marks the 20th anniversary of a tragic day in American history. Much like December 7th, 9/11 remains a “date which will live in infamy”. On this 11th day of September 2021, we think it is good for Americans to honor the sacrifice of the first responders who went to the World Trade Center (WTC) and who lost their lives. And we must remember all those who died as the towers collapsed. It is also a good time to remember those key values for which this nation stands — freedom, liberty, and justice for all. In a modern world where media sources and politicians seek to divide Americans and create hostility, the shared memory of 9/11 can perhaps serve to unite us.
Forum member Charlie NC posted: “Everybody remembers where they were when the attacks happened, and the emotions they felt. God bless the victims who died that day, and those who followed in the pursuit of justice. But at a terrible time our country was more united than at any other point in my lifetime. Hopefully may we regain that harmony again under better circumstances.”
Remembrance from 23 Years Ago — Days Before the Attack
Forum member David Joe was in New York City in September 23 years ago. David had actually been in the World Trade Center with his family just a few days before the attack. Here is his perspective on how the tragedy of 9/11 has changed life in America…
23 Years Ago at the World Trade Center…
Twenty-three years and a week ago, my wife, son, and unborn daughter spent five hours at the World Trade Center. We ate, took pictures everywhere, watched the tilting platform movie, pressed souvenir pennies, went to the top, talked to the employees and watched birthday flowers being delivered up the escalator to one of them. And that’s what we first thought about on the morning of 9/11…
By the evening of 9/11, I knew the world was different, and always would be. In all the years that have gone by, families like mine eventually travelled again, grew up and recognized at least once a year, the magnitude of the events of that day. Some think about it all the time and became more vigilant, and that is certainly, I hope, good.
Other families were directly involved daily in preventing terrorism from coming home again. Thousands of families lost relatives that day, and many more in the years after.

You can spend thousands on a rifle, but that expensive hardware won’t perform at its best if you have poor trigger technique. One key element of precision shooting is trigger control. Our friend Kirsten Joy Weiss has produced a good video that shows how to refine your trigger technique for better accuracy. In this video, Kirsten talks about the actual placement of a shooter’s index finger on the trigger. It is important to have the finger positioned optimally. Otherwise you can pull the shot slightly left or slightly right.
Kirsten tells us: “Finger placement on the trigger might not seem like a big deal, but it actually is. The reason for this is because, depending on where your index finger is placed on the trigger, [this] translates to different muscle interactions with the gun.” Watch this video to see Kirsten demonstrate proper finger placement (and explain problems caused by improper finger positioning).
When you pull the trigger, you only want to engage the last section of your finger, in order to avoid unwanted muscle engagement and to achieve a smooth shot. Remember there is a “sweet spot” between the crease (first joint) and the tip of the finger. If you position the trigger in that “sweet spot”, you should see an increase in your accuracy. Don’t make the mistake of putting the trigger in the crease of your finger, as shown below.
Effects of Incorrect Finger Placements
You want to place the trigger shoe between the end of your finger and the first joint. If you place the trigger on the very tip of you finger you’ll tend to push the rear of the rifle to the left when engaging the trigger, causing shots to go right (for a right-handed shooter). On the other hand, if you put the trigger in the crease (first joint), you’ll tend to bring the rear of the rifle to the right, causing shots to fall left. This is illustrated below for a right-handed shooter.

Sherri Jo Gallagher, the second woman in history to win the NRA High Power National Championship, sports Eye Protection at Camp Perry. The first lady High Power Champion was Sherri’s mother, Nancy Tompkins.
In response to a Bulletin article about Protective Eyewear, one of our Canadian readers posted a personal story. His account demonstrates the importance of wearing eye protection whenever you shoot — no matter what type of firearm you are using — even air rifles. We hope all our readers take this to heart. All too often at rifle matches we see shooters, even some top competitors, risking their vision by failing to wear eye protection.
Eye and Hearing Protection are now MANDATORY for Highpower Rifle competitors and Pistol shooters in all CMP-affiliated matches. Starting in 2020 the CMP Highpower Rifle, Pistol, and CMP Games Rulebooks incorporated the following rule: “All competitors and competition officials are required to wear appropriate eye and hearing protection when on shooting range firing lines during highpower rifle or pistol firing. All competitors must comply with this requirement before they can participate in a CMP sponsored or sanctioned competition. Competitors are responsible for selecting their eyewear and hearing protection.”
Eye Protection — Lesson Learned by Nicholas from Canada
As a boy on a mixed farm on the plains the first shooting stick I owned was a Red Ryder BB gun. My Dad bought it for me as I showed a keen interest in the shooting and hunting sports. I was about 9 years old at the time.
We had literally thousands of sparrows in our large farm yard and they liked to roost on the steel railings in the barn loft. I took to slowly thinning out their ranks by flashlight at night as these little winged pests settled in the farm buildings.
One evening as I slayed sparrow after sparrow in the barn loft — with about a dozen farm cats following me to consume these easy meals, I fired at another bird centered in my flashlight beam.
However, my aim was a bit low — and the copper pellet hit the steel beam square on. Instantly I felt a sharp pain as the BB bounced back and hit me squarely between the eyes on the bridge of my nose – drawing blood from the partial penetration into the skin. A half inch either way and I’d have lost an eye!
Never, never, never shoot at any target with a steel background with any firearm, even a BB gun – is the hard lesson I learned, and wear the best shooting glasses that money can buy!
PLEASE REMEMBER THAT!!
Editor’s Comment: Among competitive pistol shooters, the use of safety eyewear is universal. You’ll never see Rob Leatham, Julie Golob, or Jerry Miculek competing without eye protection — for good reason. The handgun sports’ governing bodies effectively enforce mandatory eye protection policies. We wish the same could be said for competitive rifle shooting. We often see benchrest, High Power, and F-Class competitors shooting without eye protection. We’ve heard all the excuses, yet none of them trump the safety considerations involved.
We recommend that all shooters and hunters employ eye protection whenever they use firearms or are at a location where live fire is taking place. You only have two eyes. A tiny bullet fragment or ricochet is all it takes to cause permanent blindness in one or both eyes. As rifle shooters, we place our eyes a couple inches away from a combustion chamber operating at pressures up to 70,000 psi. I know quite a few guys who will religiously put on safety glasses when running a lathe or a drill press, yet the same guys won’t use eye protection when shooting their rifles — simply because it is “inconvenient”. That’s nuts. It doesn’t matter is you are a cub scout or a multi-time National Champion — you should wear eye protection.
I will give you a personal example. A year ago I was shooting a 9mm pistol. One of the cartridges had a primer burst outward blowing small particles, some brass, and a piece of the pistol’s extractor right back into my eyes. Thankfully I was wearing good wrap-around safety glasses. No injuries at all. But without those safety glasses, this could have been very serious. I always wear safety glasses with ALL firearms. Shown below is the same kind of primer blow-out I experienced, but with a .270 Win rifle cartridge.
Be wise — protect your eyes. To learn more about eyewear safety standards, and to learn about the latest options in ANSI Z87-certified protective eyewear, read our article on Eye Protection for Shooters.

With the 6mm Dasher cartridge becoming popular with PRS/NRL competitors as well as the benchrest crowd, we thought it was time to re-visit a special rifle chambered for the 6mm Dasher wildcat. This gun has a great story behind it. Forum member Bob A. (aka “Killshot”) used his “Forum Classifieds Special” to beat all comers in the F-Class Division in the American-Canadian Match and the Long Range Regional Match in 2013 in Sacramento, CA.
Bob’s 6mm Dasher sports a blue-printed Rem 700 action. Who says you need a high-dollar custom action to run with the big dogs? In fact, this same gun, built with components sourced from AccurateShooter Forum Classified Ads, set a Sacramento F-Class range record of 200-17X a few years back. In this story, Bob talks about the build, and he explains his methods for loading ultra-accurate Dasher ammo.
Bob’s Budget-Build Dasher F-Classer
I wanted to build a proper rifle for F-Open but needed to keep it simple and, well, cheap. I found a solid “base” to build on in the form of a Dave Bruno-built, “pre-owned” 6-6.5×47 Lapua that I located in the AccurateShooter Forum classifieds in late 2011. The base action was a trued and blue-printed Remington 700 receiver circa 1971 with a spiral-fluted bolt. It was in a Shehane ST1000 stock painted sky blue and had a Jewell 1.5-oz BR trigger. I sent the bolt to Greg Tannel (Gretanrifles.com) to have the firing pin hole bushed and sleeved, the ejector removed and the hole filled and the face trued. I upgraded to Tannel’s Light Steel firing pin assembly while it was out.
Having the working bits completed, I needed a barrel. So I went to the AccurateShooter classifieds again and found a 1:8″-twist, 30″ x 1.25″ (diam.) Bartlein with a 0.236″-land bore. I called Dave Kiff and explained my pursuit and he recommended his PT&G “world record” 6 Dasher reamer (.2704″ no-turn neck and .104″ freebore). A month or so later the reamer and gauges arrived.
I had the barrel chambered by Marc Soulie of Spartan Precision Rifles (510-755-5293, Concord, CA). Marc is a great builder and I’m pleased to call him a friend.
The rifle got its good looks from a Pennsylvania artist named Kenny Prahl. His Prahl Designs shop (724-478-2538) added the white ghost-flames over the existing sky blue metallic paint.
Looks Great, Shoots Better
Fire-forming showed great promise — ten-shot groups of half an inch at 200 yards were typical. I lost only one case to a split neck and the “blow lengths” are good and consistent. This was followed up with load development which saw 100-yard, five-shot groups in the .1s and .2s as the rifle showed its preference for Reloder 15 over Varget powder, and for CCI 450s over all other primers. The bullet of choice was the ever-popular Berger 105gr Hybrid Target.
In February 2012 I began shooting the Dasher in monthly club matches at the Sacramento Valley Shooting Center, the home range of a number of excellent F-Class, Benchrest and High Power shooters. Using a Farley Coaxial rest up front (also picked up from a WTB ad on AccurateShooter’s Forum) and an Edgewood bag in the back, I gradually improved my gun-handling to the point where I could shoot a respectable score. This was very different from the bipod shooting I’d done in the past in F/TR.
Dasher Loading Tips
My chamber is set up for blue box Lapua 6mmBR brass. My case preparation is straight-forward. I fire-form with virgin cases right out of the box. I don’t size them but I will give the primer holes a good look and clean up the flash hole with a .058″ bit in a pin vise. To fire-form, I seat a Berger 108gr BT .030″ into the lands over a standard 6mmBR load of Varget.
For match loads, I use Alliant Reloder 15. While Varget is less sensitive to temp changes, RL15 has given me lower extreme spreads and better long range control. [Bob acknowledges that every barrel is unique, so a different powder, such as H4895 might work better for you.]
I clean my fired cases with stainless steel media in a Thumler’s rotary tumbler after every firing. I anneal after every other firing using a Bench-Source machine which is very well made and easy to operate. I use a Whidden full length bushing die with Redding bushings for sizing.
After sizing, I chamfer the inside of the neck with the K&M tool which has a pilot rod centered in the flash hole. Then I’ll give the neck and mouth a “once over” with some 0000 steel wool. I finish loading off with a Redding Competition Seating Die with the micrometer top.
I use a carbide ball on the expander rod of the full length sizing die. I use a .266″ TiN-coated bushing and the ball just kisses the inside walls of the sized neck. I get very consistent neck tension this way and have had no issue with split necks.
Seating Depth Considerations
With fire-formed brass, the junction of the bullet’s bearing surface and boat-tail is above the neck/shoulder junction of the case, so I have no issues with donuts. You can see how a loaded round looks in the photo at left. For occasional trimming, I use a very nice little Possum Hollow trimmer that indexes on the case shoulder.

The author’s favorite pistol round is the 9mm Luger: “9mm is my personal favorite and if there was a “Goldilocks” round, this would be it. The very first gun I bought was a 9mm. They’re fun at the range. They’re good for defense. It is the standard round for NATO countries and the majority of police forces around the world. It is mild shooting, can vary in weight from 115 to 147 grains, and has varying stopping power based on the type of bullet.”
This Pew-Pew Tactical guide to cartridge types also provides a quick explanation of cartridge ignition — both centerfire and rimfire: “The rimfire’s primer is built into the rim while the centerfire cartridge has the primer in the center. Pro tip — if you can see a circle in the middle…it’s a centerfire cartridge.”
There are two common types of centerfire primers — Boxer and Berdan. This helpful Wikipedia illustration shows how Boxer, Berdan, and rimfire primers ignite the powder in the cartridge:
