It’s October 31st, All Hallows’ Eve, (aka “Halloween”). That means the neighborhood kids will be ringing doorbells as soon as it gets dark. No doubt some of you proscrastinators will wait ’til the last minute to set out your Halloween decorations and Jack-O-Lanterns. Don’t worry, in the video below, our friend, 3-Gun ace Taran Butler, shows how to carve a pumpkin in just about 5.5 seconds, give or take a tenth. Taran performed this feat of speed-carving with his trusty Infinity handgun, chambered in 9mm Major.
What Are the Origins of Halloween?
Halloween or Hallowe’en (a contraction of “All Hallows’ Evening”), also known as All Hallows’ Eve, is a yearly celebration observed on October 31, the eve of the Western Christian feast of All Hallows (or All Saints). According to many scholars, it was originally influenced by western European harvest festivals and festivals of the dead with possible pagan roots, particularly the Celtic Samhain. Others maintain that it originated independently of Samhain and has Christian roots.

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.

Kirsten Joy Weiss is a phenomenal off-hand rifle shooter. In this video, Kirsten performs a classic Annie Oakley trick shot, cutting a playing card in half with a bullet. Splitting a playing card would be hard enough with a scoped rifle shot from the bench. But Kirsten makes this amazing shot from standing position, shooting over iron sights, with an inexpensive rimfire lever gun. Trust us, that’s not easy. It did take Kirsten three tries, but we’re still impressed.
To accomplish this trick shot, Kirsten’s horizontal aim had to be ultra-precise. A playing card is only 0.25mm thick (about 1/100th of an inch). That leaves almost no room for error.
GIF Animation Shows Bullet Slicing Card in Half:
We know top benchresters can put five shots in one ragged hole at 100 yards, used a scoped rifle sitting on a stable rest. But make those folks stand on their hind legs, hold the rifle, and aim over primitive iron sights, and some of those benchrest aces would be lucky to hit a dinner plate at 100 yards. Kudos to Kirsten for making this great shot.

Thomas Haugland, a Shooters’ Forum member from Norway, is a long-range target shooter and hunter. He has created an interesting video showing how to gauge wind velocities by watching trees, grass, and other natural vegetation. The video commentary is in English, but the units of wind speed (and distance) are metric. Haugland explains: “This is not a full tutorial, but rather a short heads-up to make you draw the lines between the dots yourself”. Here are some conversions that will help when watching the video:
.5 m/s = 1.1 mph | 1 m/s = 2.2 mph | 2 m/s = 4.5 mph
3 m/s = 6.7 mph | 4 m/s = 8.9 mph | 5 m/s =11.2 mph
What would it be like to have a tracer round fly right past your eyeball? You’d never want to experience that in real life. But here’s an amazing short video that lets you see a “target-eye’s view” (POV) of an incoming tracer round. If you look carefully, you can actually see the bullet spinning (throwing off radial sparks) before it strikes the target.
Watch Incoming .22 LR Tracer Round:
YouTube shootist “22 Plinkster” placed a miniature video camera behind bullet-proof glass then fired a .22 LR tracer round right at the camera. With slo-mo playback, you can see the tracer leave the rifle barrel and fly directly at the camera, showing bright red sparks all the way. In this video, 22 Plinkster shoots a .22 LR tracer round at a camera protected by a layer of bulletproof glass. After the impact, there is a dark black crater left in the glass (lower photo).

Frank Galli (aka “Lowlight”), the head honcho of Sniper’s Hide, has created a good 15-minute wind-reading video for the Scout web network. This video, a segment from the Sniper’s Hide Day One DVD, covers many of the important basics of wind reading. It’s a helpful introduction for those getting started in long-range rifle shooting.
Quote 1: “On the range, people describe the wind as the Great Equalizer. Next to your drop, drift from wind is the second most important consideration for the long range precision rifle shooter. Unlike drop, which is predictable, the wind is a constantly changing factor.”
Quote 2: “Wind is like water. It’s important to understand how terrain will effect the wind, how it will change the direction, velocity and consistency. It’s responsible for turbulence, it’s responsible for unseen changes that will throw our shot off. Wind will ebb and flow just like waves crashing on the beach. We need to understand the frequency and velocity of each wave.”

Accuracy International (AI) is perhaps the most noted manufacturer of bolt-action sniper rifles in the Western world. AI was founded in the 1980s by Dave Caig, Malcolm Cooper, and Dave Walls, three competitive rifle shooters. The company took its name from Cooper’s shop: Accuracy International Shooting Sports. The first project was a smallbore target rifle for civilians. Then the trio decided to build a 7.62×51 sniper rifle, inspired by a UK Ministry of Defense (MoD) competition to replace the venerable L42A1. (That old, wood-stocked design had proven unsatisfactory in the 1982 Falkland Islands conflict.)
Working in a garage workshop, Walls and his partners combined their knowledge of target shooting with input from active military personnel to create the first AI sniper rifle, the L96A1. This ground-breaking design won the MoD contract and immediately proved successful in the field. In an interview with The Telegraph, Walls explained: “The company’s early success was based on not just the what the founders knew from target shooting but also what they learnt from the users, the military users. They went out and they sought inputs from those users, and based on that they designed their very first sniper rifle, and it was very successful.”
Today, “At a discreet location on the outskirts of Portsmouth”, Accuracy International continues to make rugged, versatile, and ultra-accurate sniper rifles for military, law enforcement, and private use. A team from The Telegraph visited the Accuracy International facility in England earlier this year. The video below shows AI’s facilities and the products AI produces:

Profile of Accuracy International in The Firearm Blog
If you want to learn more about Accuracy International, you’ll find an excellent company history in The Firearm Blog (TFB). Writer Miles Vining visited AI’s Portsmouth facility and toured the factory. His in-depth TFB article provides some fascinating insights. For example, Vining recounts that struggles AI went through before reaching its current success:
“The company wasn’t an immediate success in the beginning. After winning the British Army contract and the MoD realizing the gun was constructed in a garage, Accuracy International had to subcontract many of its parts out to various companies around the UK. In 2000, after over 15 years of production, the company only had two CNC machines, one of which didn’t even work and the other one was making front sight posts…. During the 1990s Accuracy International was surviving on contract to contract, barely making ends meet.”
A major turn-around came with the creation of AI’s Arctic Warfare rifle for the 1993 Swedish trials. As chambered in .338 Lapua Magnum, this AW rifle proved to be a game-changer that “carried the company through the 1990s”. In 2005 the enterprise did go through a re-organization with Tom Irwin and Dave Walls taking over as sole Directors. Since then, AI has been going strong for the past decade. It now produces almost all components in-house, with 30 CNC machines, 70 employees in the UK, and two large-scale manufacturing plants.

I first met Anette Wachter four years ago at the NRA’s National Long Range High Power Rifle Championship in Camp Perry, Ohio. A statuesque brunette, Wachter easily stood out in the crowd. I just so happened to be a big fan of her twitter feed as well. After a quick exchange of pleasantries, we talked about shooting, life in Washington, and how she could get more involved.
Since then she has become very involved. Her 30 Cal Gal blog has become a favorite of male and female shooters alike. Due to her diligence, she was also about to earn a spot on the U.S. National Palma Travel Rifle Team. And recently, Wachter lent her voice and views to the battle for gun rights in the state of Washington.
