Here’s a shocking video showing a massive Kaboom (KB) that literally destroyed an M1 Garand in the hands of a lady shooter. One second she has a classic .30-06 battle rifle in her arms, and the next second she has nothing but a pile of parts. She is fortunate to have survived this incident without apparent serious injury. She may have had a squib (undercharged round) in her prior shot at the 00:12 time-mark. At 00:15 it seems she may have experienced “click no bang” (we can’t tell for sure). The detonation occurs at time-mark 00:25, and is then replayed in slow-motion.
 If this Kaboom wasn’t caused by a squib, there might have been a catastrophic failure of the cartridge that failed to fire at 00:15. The shooter herself, posting as ArizonaGirl24 on YouTube, thinks the gun may have fired out of battery. What do you think?
Text accompanying the posting of this video on LiveLeak, states: “A woman, her shooting partner, and their cameraperson are lucky to be alive. Her M1 Garand detonated after she failed to check the barrel for an obstruction due to an apparent squib round….
[After the shot at 00:12] she is obviously aware that something is amiss and seems to check the chamber, but does not unload the rifle to check for the presence of a barrel obstruction.
She raises the rifle and fires it again, causing a catastrophic weapon failure. Parts of the weapon fly in all directions. The video then terminates.”
What happened to the shooter? She reported: “I was very lucky with the outcome. I have lots of splinters and bruising, but nothing broken. My left hand took the brunt of the blow to my wrist and palm of my hand. Still pretty painful, but I will be fine.”
LESSON ONE: If you experience any kind of malfunction, or what appears to be a light-recoiling (or soft-sounding) shot, you should STOP shooting immediately. Clear the firearm and check for barrel obstructions.
LESSON TWO: Always wear ear and eye protection when shooting any firearm, even rimfires.
LESSON THREE: With a semi-auto gun, ensure the bolt is completely in battery after every shot.
LESSON FOUR: When hand-loading check EVERY round for powder charges prior to seating bullets, and weigh your loaded rounds before boxing them. Also check for high primers on EVERY round. If using a progressive press, use a Lock-Out Die that will alert you to any under-loaded cartridge. Be wary of commercial reloads.

Sierra Bullets has released Version 7 of its respected Infinity Exterior Ballistics software, available now for $39.95 for Windows computers. Renowned Sierra Ballistic Consultants Ted Almgren and Dr. Bill McDonald, who have written all Sierra Software since 1970, also wrote Infinity Version 7. Both are retired scientists from a major aerospace company. Infinity Exterior Ballistics Software version 7 is a sophisticated solver that can output multiple trajectory charts. A built-in database includes bullets and cartridges offered by 15 manufacturers, both U.S. and foreign.
This 13-minute Video Demonstrates the Many Features of Infinity 7 Ballistics Software:
This sophisticated program computes the effects on the bullet trajectory of variations in firing conditions. For example, you can change altitude of the firing point, target angle (uphill/downhill), wind speeds, or even modify the Ballistic Coefficient. In fact, you can change any inputted firing condition or combination of conditions.
One very handy function is the “back-to-zero” calculation. Infinity 7 software will compute where your gun is zeroed if you know that it shoots high by a measured amount at a known range.
Compare Trajectories with Five Different Bullets
One very powerful feature of Infinity 7 is its trajectory comparison capability. With most ballistics programs (such as the JBM online ballistics calculator), you can only view one bullet’s trajectory (and associated drop chart) at a time. Not so with Infinity 7. This software handles up to five different bullets at a time. You can compare downrange velocity, energy, drop, bullet path height, or crosswind drift with results shown in bolt tabular and graphical format. That helps you select the best bullet for your gun and application. The ability to compare downrange ballistics of five different bullets at once is particularly helpful for hunters, who can compare the “hitting power” of different projectiles at various distances.
You can purchase Infinity 7 Ballistics Software as a standalone product for $39.99, or you can buy the Infinity 7 Suite for $59.95, which includes the Sierra Bullets 5th Edition Reloading Manual on CD-ROM. If you prefer a printed loading Manual, a combo pack with Infinity 7 software CD-ROM plus published (hard-back) Reloading Manual is offered for $64.95.

How much can you save reloading your own ammo? Well that depends on the cost of components and how much you have invested in your reloading gear. UltimateReloader.com has created a handy online Reloading Costs Calculator that lets you quickly compare the cost of reloaded ammo vs. factory ammo. Just enter the costs of powder, primers, bullets, and brass, and the Calculator will tell you the cost per round, per 20-rd box, per 50-rd box, and cost per thousand. Note — when setting the price of the brass you need to divide the initial cost by the number of predicted reloads. For example if you have 500 pieces of brass that cost $40/100 to buy ($200 total), but you get 8 reloads per case, then you put $25.00 in the Calculator ($200 total brass cost divided by 8).
True Reloading Cost Should Include Amortized Tool Expenses
Ah… but there is a catch. To understand the true cost of reloading, you also need to consider the costs of your tools and accessories, amortized over the tools’ loading lifespan. Let’s say you have $1000.00 invested in presses, dies, tumblers, measuring tools and other accessories, with a residual value of $500.00 (upon resale). If you load 5,000 rounds with those tools over their lifespan, you need to add $0.10 per round for tooling costs (your investment minus residual value, divided by the number of rounds loaded). The UltimateReloader.com Calculator does not include amortized tooling costs, but that’s something you can easily figure out on your own.
Excellent Resource for Reloading Videos
After you’ve tried out the Reloading Costs Calculator, check out the other content on UltimateReloader.com. This site features some of the best gun-related “how-to” videos on the internet. With sharp video and clear audio, the production quality is very high. If you use a progressive press (Dillon, Hornady, RCBS), you should definitely watch UltimateReloader.com’s videos — you’ll probably learn a new trick or two. In the sample video below, you can see how Hornady’s new Bullet Feeder works with its Lock-N-Load Progressive press.

The FBI released its annual Crime in the United States report on November 10, 2014. This study revealed that, in 2013, the USA violent crime rate fell another 5.1 percent from 2012, so it is now at its lowest level since 1978. Moreover, the murder and manslaughter rate fell 4.4 percent, dropping to the lowest level since 1968.
This is very good news. From a public policy perspective, this is very important data that should help inform decision-making. The NSSF urges gun-owners to cite these statistics when unreasonable or irrational new gun control laws are proposed.
 More Guns, Less Crime
While the crime rate has been dropping steadily for more than 20 years, the number of firearms in the hands of law-abiding Americans has been rising dramatically. So, statistics prove that we really have witnessed “more guns, less crime”. Earlier this year, the NSSF released a video that demonstrates this point very effectively:
63% of Americans Believe Gun in Home Increases Safety
A new Gallup survey released last week that found 63 percent of Americans believe that having a gun in the house makes it a safer place, a doubling of that number since 2000. The fact that more than six out of ten Americans have reached this conclusion demonstrates that the majority of Americans appreciate their Second Amendment rights to defend home and family.
What Counts as “Violent Crime”?
In the FBI’s Uniform Crime Reporting (UCR) Program, violent crime is composed of four offenses: murder and nonnegligent manslaughter, rape, robbery, and aggravated assault. Violent crimes are defined in the UCR Program as those offenses which involve force or threat of force.
Long-Term USA Crime Trends
In 2013, an estimated 1,163,146 violent crimes occurred nationwide, a decrease of 4.4 percent from the 2012 estimate. When considering 5- and 10-year trends, the 2013 estimated violent crime total was 12.3 percent below the 2009 level and 14.5 percent below the 2004 level. There were an estimated 367.9 violent crimes per 100,000 inhabitants in 2013, a rate that declined 5.1 percent when compared with the 2012 estimated rate.

Here’s an interesting video about three-position shooting. Produced by GOnra Media, this video demonstrates rifle hold and body alignment for prone, standing, sitting, and kneeling positions. Olympic Gold Medalist Jamie Gray demonstrates the proper stance and position of arms and legs for each of the positions. Ideally, in all of the shooting positions, the shooter takes advantage of skeletal support. The shooter should align the bones of his/her arms and legs to provide a solid foundation. A shooter’s legs and arms form vertical planes helping the body remain stable in the shooting position.

Want to see how some of the best rifle shooters in the world operate in high-stakes, 1000-yard competition? This video shows Team Sinclair powering to victory at the 2014 F-Class National Championships in Phoenix. Scoring an impressive 792-38X, Team Sinclair topped the field, winning the 4-man team title and setting a new 1000-yard F-TR National Team Record in the process. It was a close match, with America’s “powerhouse” F-TR teams battling it out for the top three spots: Team Sinclair (Gold), Team X-Men (Silver), and Team Michigan (Bronze). Team Sinclair’s wind coach Ray Gross did a superb job. Ray also serves as the Captain of the USA F-TR Rifle Team.
Along with the Team Sinclair shooters, this video also features Team X-Men (orange shirts), and Team Michigan. Starting at the 2:05 time-mark, you can hear Bryan Litz calling wind for Team Michigan. Watch the mirage in the video and see if you can match Bryan’s wind calls with the movement of the mirage. This is a great opportunity to see F-TR Top Guns in action. Team score cards appear in the video, starting at the 3:01 time-mark.

 In discussions of ballistics, you’ll see references to “tangent” and “secant” bullet shapes. We know that, for many readers, these terms can be confusing. To add to the confusion, bullet makers don’t always identify their projectiles as secant or tangent designs. This article provides a basic explanation of tangent and secant designs, to help you understand the characteristics of both bullet shapes.
Tangent vs. Secant vs. Hybrid
Most match bullets produced today use a tangent ogive profile, but the modern VLD-style bullets employ a secant profile. To further complicate matters, the latest generation of “Hybrid” projectiles from Berger Bullets feature a blended secant + tangent profile to combine the best qualities of both nose shapes. The secant section provides reduced drag, while the tangent section makes the bullet easier to tune, i.e. less sensitive to bullet seating depth position.
Berger Bullets ballistician Bryan Litz explains tangent and secant bullet ogive designs in a glossary section of his Applied Ballistics website, which we reprint below. Bryan then explains how tangent and secant profiles can be combined in a “hybrid” design.
How Bullet Ogive Curves are Defined
While the term “ogive” is often used to describe the particular point on the bullet where the curve reaches full bullet diameter, in fact the “ogive” properly refers to the entire curve of the bullet from the tip to the full-diameter straight section — the shank. Understanding then, that the ogive is a curve, how is that curve described?
LITZ: The ogive of a bullet is usually characterized by the length of its radius. This radius is often given in calibers instead of inches. For example, an 8 ogive 6mm bullet has an ogive that is a segment of a circular arc with a radius of 8*.243 = 1.952”. A .30-caliber bullet with an 8 ogive will be proportionally the same as the 8 ogive 6mm bullet, but the actual radius will be 2.464” for the .30 caliber bullet.
For a given nose length, if an ogive is perfectly tangent, it will have a very specific radius. Any radius longer than that will cause the ogive to be secant. Secant ogives can range from very mild (short radius) to very aggressive (long radius). The drag of a secant ogive is minimized when its radius is twice as long as a tangent ogive radius. In other words, if a tangent ogive has an 8 caliber radius, then the longest practical secant ogive radius is 16 calibers long for a given nose length.”
Ogive Metrics and Rt/R Ratio
LITZ: There is a number that’s used to quantify how secant an ogive is. The metric is known as the Rt/R ratio and it’s the ratio of the tangent ogive radius to the actual ogive radius for a given bullet. In the above example, the 16 caliber ogive would have an Rt/R ratio of 0.5. The number 0.5 is therefore the lowest practical value for the Rt/R ratio, and represents the minimum drag ogive for a given length. An ogive that’s perfectly tangent will have an Rt/R ratio of 1.0. Most ogives are in between an Rt/R of 1.0 and 0.5. The dimensioned drawings at the end of my Applied Ballistics book provide the bullets ogive radius in calibers, as well as the Rt/R ratio. In short, the Rt/R ratio is simply a measure of how secant an ogive is. 1.0 is not secant at all, 0.5 is as secant as it gets.
 Hybrid Bullet Design — Best of Both Worlds?
Bryan Litz has developed a number of modern “Hybrid” design bullets for Berger. The objective of Bryan’s design work has been to achieve a very low drag design that is also “not finicky”. Normal (non-hybrid) secant designs, such as the Berger 105gr VLD, deliver very impressive BC values, but the bullets can be sensitive to seating depth. Montana’s Tom Mousel has set world records with the Berger 105gr VLD in his 6mm Dasher, but he tells us “seating depth is critical to the best accuracy”. Tom says a mere .003″ seating depth change “makes a difference”. In an effort to produce more forgiving high-BC bullets, Bryan Litz developed the hybrid tangent/secant bullet shape.

This Wednesday, October 29, Shooting USA TV features the Bushnell Brawl, a tactical competition that draws top long-range shooters from the military, law enforcement and the civilian shooting communities. The match is held at the famed Rifles Only range in Kingsville, Texas. The Brawl is a one-of-a-kind physical and mental challenge — 20 events test each shooter’s ability to read wind, figure ballistics, and adapt to difficult shooting scenarios. And, each year, the competition proves to be even more challenging. There is even a helicopter stage.
“Whenever the difficulty ramps up, they step up, and we’ve seen it for the last fifteen years doing matches,” says Rifles Only Director, Jacob Bynum. “Ramp up the difficulty, quality goes up.”
The signature event is Trench Warfare, where each competitor gets a chance to shoot from a helicopter before running to the trench. Competitors also shoot from the tower, where shots are out to 1,000 yards. Not all events are shot over long distance. The Five Dot Drill and Know Your Limit on paper are shot inside 100 yards.

Hey guys here’s a torture test video that’s really worth watching — you’ll be shocked and amazed (we guarantee it). In this video, Nightforce Exec Kyle Brown (with help from NF employee Sean Murphy), absolutely brutalizes a Nightforce NXS 5.5-22x56mm scope. He bangs it on a concrete bench-top, throws it 50 yards downrange, knocks it on a hardwood beam multiple times, and then heaves it back again. We kid you not. To our eternal surprise, the Nightforce scope survives all that abuse and shoots fine. What did Timex once say — “Takes a licking and keeps on ticking”?
You’ve got to watch this video — it was shot with five cameras and runs with no “time-outs”, cutaways, or video tricks. What you see is what you get. This is one tough NXS. Thank you Kyle Brown and crew for taking the time to prove the durability of Nightforce Optics products.
