Lapua now offers a FREE ballistics program for modern smart phones that run Java Apps. (Unfortunately, that excludes Apple iPhones and Android OS phones, but Lapua says that the majority of smartphones run Java). The program calculates drift and drop, and it corrects for altitude, temp, air pressure, and shot angle. The Lapua Ballistics App also includes a database of Lapua bullet profiles with ultra-reliable radar-derived Ballistic Coefficients. Sound good? Now go get your smart phone. The program must be downloaded with a mobile phone. Open a web browser in your smart-phone and navigate to www.lapua.com/ballistics and choose the correct version for your phone.
Lapua’s exterior ballistic software for mobile phones is capable of predicting trajectories in real time with extreme accuracy. Using Lapua Ballistics, there is no need for checking tables and calculating cosines for inclination compensation (you still have to input the angle). The program also compensates for the effect of cartridge temperature on muzzle velocity and the effect of atmospheric conditions on the projectile’s trajectory.
Lapua Ballistics is based on precise Doppler Radar measurements of actual bullet drag — professional data available only for Lapua bullets. Lapua Ballistics can be installed on all smartphones supporting basic Java (Java MIDP 2.0). NOTE: Apple iPhone and Android platforms do not support Java ME.

I’d like to make everyone aware of a new ballistic solver called the Whiz Wheel. The Whiz Wheel, from Accuracy 1st Development Group (Accuracy 1st) is a non-electronic device that calculates ballistic solutions out to transonic range for any small arms bullet. This device, similar to a circular slide-rule, is in the process of being adopted by several military units as a back-up to the electronic PDAs, and even as the primary ballistic solver since it’s faster to get a solution compared to the PDAs.
Whiz Wheel Solver Features include:
Density altitude calculator
Meters/MILS or Yards/MOA output
Trajectory prediction within 0.1 MIL or 0.25 MOA resolution
Wind deflection for any speed and direction
Spin drift
Leads for engaging moving targets
Corrections for inclined shooting
Ability to ‘true’ the solution for variations in MV or BC
Use Different Wheels for Various Cartridges and Loads
The tan colored sleeve is universal, meaning it works with all load-specific wheels. The wheels are interchangeable laser-engraved plastic items. Accuracy 1st offers both “standard” wheels for popular factory-loaded ammo types, as well as custom wheels tailored to your specific bullet, MV, sight height, and twist rate. Each wheel provides a full solution for a single cartridge type and load. Different wheels are required for different cartridges/different loads. This is because the wheel’s solutions depend on bullet BC and muzzle velocity.
How to Use the Whiz Wheel
Finding your come-ups (and windage corrections) with the Whiz Wheel is very simple. Start by solving the density altitude (DA) with the small wheel, or getting it from a Kestrel. Then line up the DA with the range, and the wheel outputs drop. The drop can be corrected for incline via the table on the back of the sleeve. The back of the whiz wheel also calculates the lateral solution elements including wind, spin drift, and moving target leads.
I was heavily involved in the development of the Whiz Wheel and can vouch for the accuracy of the solutions which are generated with a point mass solver and measured G7 BCs. If you have comments or questions about the Whiz Wheel, you can place those in the comments section for this Bulletin post. I’ll try to respond to your questions, time permitting.

GS Custom Bullets has been producing high-quality hunting and target bullets in South Africa since 1993. GS Custom Bullets specializes in monometal solids. For hunters, the GS solids have proven extremely effective on game animals, including the biggest species on the African continent. The GS match bullets are CNC-machined to very exacting tolerances, offering superior concentricity and uniformity. The large match bullets feature drive bands for reduced engraving force, and an extremely slippery shape for exceptionally high ballistic coefficients. GS has made a special 1,100-grain 50-caliber projectile that has a calculated G1 BC of 1.85! This bullet, launched at 3400 fps, can stay supersonic out to 4,000 meters — that’s 2.49 miles!
Gerard Schultz, founder of GS Custom Bullets, holds a number of patents on his bullet designs. Currently GS Custom is selling to the American market through its South African website, GSCustom.co.ZA. However, this year GS Custom hopes to expand production to North America, starting a production facility in the USA. The North American effort will be lead by Gerard Schultz’s daughter, Gina, and her husband Anthony. They can be contacted through GSCustomUSA.com. We met with Gina and Anthony at SHOT Show in Las Vegas and learned more about these remarkable bullet designs. The video is worth watching. These are no ordinary bullets.
JBM Ballistics (JBM), based in Las Cruces, NM, has provided free online ballistics info for the past 15 years. JBM Ballistics’ sophisticated algorithms deliver extremely reliable ballistics solutions. To complement its software, JBM plans to introduce a new hardware product: the BallistiComp.
Laster this year, JBM will unveil its new BallistiComp, a portable handheld ballistics computer that measures atmospheric temperature and pressure. Once your load data (Bullet BC, Velocity) is entered, the BallistiComp provides instantaneous drop and windage corrections for your load and shooting conditions. Calculated parameters include drop, windage, coriolis, drift and lead, plus terminal information including velocity, energy, time of flight and danger space. All of these parameters are displayed on an LCD display with backlight. Small enough to fit in your pocket, the BallistiComp is packaged in a rugged, watertight Lexan® case, measuring about 3″x5″x1″.
Why Not “An App for That”
Why would JBM produce dedicated hardware when there are good Ballistics Apps that can run on an Apple or Droid smartphone? Battery life is one reason. The single 9-volt battery should last for months (by contrast some smartphones need to be charged every DAY). Importantly, no connection to cell towers or the internet is needed. You could use this unit anywhere on the globe. Lastly, JBM wanted something that was inherently rugged and reliable. Smartphone touch screens are notoriously fragile.
How It Works
Using an 8-button keypad, you enter your firearm, ammunition and zero parameters into the system memory. BallistiComp then calculates the bullet drop and windage correction at the current atmospheric conditions, latitude and altitude (or calculated pressure altitude). BallistiComp continually measures the air temperature and pressure and provides constantly updated drop and drift numbers.
Product Availability
JBM has not yet disclosed a launch date or a suggested price for the new BallistiComp. However, you can download an Operators Manual to learn more about the BallistiComp. JBM cautions: “The manual is just a draft and may change during beta testing”.
Nikon has adapted its popular Spot On Ballistics software to run on iPhones and iPods. The Spot On iPhone App contains a vast database of factory ammo (both rimfire and centerfire), so you can quickly plot ballistics for your chosen load. If you have a Nikon scope with a Ballistic Drop Compensating Reticle (BDC), you can input the ammo type, zero distance, and atmospheric conditions, and the software will automatically calculate exact target distances corresponding to the hold-over circles on your reticle. Match Technology provides precise aiming points for any Nikon BDC reticle riflescope and precise reference for sighting in other Nikon riflescopes with plex, MilDot or standard crosshair reticles. Nikon’s Spot On App costs $4.99 from the iTunes App store.
Free Web Version of Nikon’s Ballistics App
If you don’t own an iPhone, you can still use the full-featured Spot On program for free on the web. Just log on to NikonHunting.com/spoton and register. Pick a caliber/cartridge and a bullet, then input temp, altitude, and shooting angle. This will give you a ballistics solution and will show the actual yardages corresponding to your BDC reticle hold-over circles. Shown below is the user interface for the FREE web-based version of Spot On.
Just when we thought we’d seen everything, Horus Vision has teamed up with 5.11 to create a wristwatch with a built-in ballistics calculator. Priced at $199.95, the 5.11 Ballistics Field Watch incorporates the Horus Vision SureShot™ ballistic calculator, plus a digital compass to indicate direction and degree. The watch has a molded polycarbonate body, offered in three color choices: black, olive drab, and coyote tan. Equipped with a backlight for night use, the 5.11 Field Watch also features dual time zones, a stopwatch, a countdown timer, and alarm.
Full-featured Ballistics Calculator
The ballistics functions are fairly complete. Using the four control buttons you can input temp, scope height (above bore), altitude, zero range, target distance, inclination (up/down angle), wind speed, wind direction, bullet BC (Ballistic Coefficient), and Muzzle Velocity. Then the watch will calculate your elevation and windage correction in either Mils or MOA-fraction clicks. It’s amazing that Horus packed all these features into a normal-sized watch.
NOTE: This online product demo is very cool. By clicking the buttons on an interactive watch mock-up, you can test all the functions and see how to input values into the Ballistics Calculator.
We haven’t compared the Horus/5.11 Ballistics Calculator watch with more sophisticated ballistics programs, but if you can remember all the buttons to push (and in what order) this watch appears to be a compact alternative to a laptop or PDA with ballistics software installed. Buyers have rated the watch highly: “Brillliant — I ordered the 5.11 Tactical Field Watch for my husband to use on his tour in Afghanistan. He loves it. He loves every feature it comes with and says that it’s accurate and durable.”
Elcan ushers in the age of digitally-enhanced scopes with its amazing Digital Hunter. It’s about time digital features were added to consumer rifle scopes. In many respects a $150.00 point and shoot camera is much more sophisticated than a $2600.00 Schmidt & Bender. Adding a digital image sensor and digital “crosshairs” to a telescopic lens system unlocks an amazing realm of possibilities. First, you can eliminate moving parts, including the reticle itself, avoiding the possibility of reticle movement that could alter your zero. With digital crosshairs “informed” by a ballistics calculator, the reticle’s aimpoint can automatically display the correct hold-over at any target distance. For low-light shooting, you can boost the brightness and contrast of the image. You can even hook up the scope to a remote monitor so an instructor or spotter can see exactly what the shooter is seeing. Last but not least, everything viewed through the scope can be digitally recorded for later playback and analysis. This way a hunter can record, for posterity, the moment he bagged a trophy buck. Or, a military sniper can record a complete target engagement, for later review by his commander and fellow marksmen.
The $1199.00 Elcan Digital Hunter offers a 2.5-16.5X digital zoom, four field-selectable reticles, and built-in video capture. Reticles can be changed ‘on the fly’ and you can output the video to an external monitor, or simply pop out the SD flash memory card to play back video files on your computer.
Electronic Zoom with No Moving Parts
There are no moving parts in the Digital Hunter except for the diopter adjustment. Magnification is accomplished electronically, and the aiming point does not change at all during magnification. The electronic magnification is parallax-free and the exit pupil remains constant, allowing easy target acquisition, even at high power. Elcan claims that resolution does not change significantly from wide field of view to narrow field of view.
Electronic Ballistic Compensation
One of the most useful features of the Digital Hunter is electronic ballistic compensation. Here’s how that works. The scope has a USB port to connect with a computer. Using Elcan-provided PC ballistics software, you input Bullet BC, Muzzle Velocity, and even wind speed and angle. The scope’s processor automatically calculates drift and drop for various distances and then positions the digital aim point for the correct holdover, based on the target distance you select. All the critical calculations are handled automatically. Watch the video below to see how this all works.
Day-Night Digital Hunter In addition to the standard Elcan Digital Hunter, Elcan offers a version for low-light shooting. The Day/Night Digital Hunter, priced at $1399.00, can be combined with IR (infrared) “flash-lights” to provide full night-hunting capability. Low Light mode displays all the available visible light and the near infrared light (that can be “seen” by the scope’s image sensor, but not by the human eye). Utilizing the near infrared means more light energy is available to the scope for better, brighter imaging. After dark, active night vision enables covert surveillance and varmint hunting (where legal). The effective range of the active night vision depends on the power of the IR Flashlight(s).
Remote Viewing Capability Helps Disabled Shooters
When the Elcan Digital Hunter was first introduced a couple years ago, Outdoors writer Ray Sasser of the Dallas Morning News field-tested it with Ray Mauldin, Elcan Products Manager. Sasser wrote: “There’s a new rifle scope technology on the horizon, a spin-off from military developments made by the Raytheon Company [parent company of Elcan]. The software calculated bullet drop… and the information was stored in a computer chip inside the scope. The only two drawbacks I could find were price and weight. The digital scope weighs 26 ounces, nearly seven ounces heavier than Leupold’s LPS 3.5-14x50mm, my personal favorite traditional scope. Mauldin said physically challenged hunters are particularly excited about the Digital Hunter. It can be used with a video monitoring screen so the rifle can be sighted without your eye to the scope. That’s a huge advantage for a quadriplegic, one-armed or no-armed shooter.”
Digital Enhancements for Target Scopes?
Traditionalists may scoff at digital scope technology, thinking that something like the digital Elcan could never be used in a match because it is too big and heavy. But consider this — all you really need on top of the rifle is the lens system with light sensor. All the other controls and the display could be moved off the rifle and built into a benchtop display/control/processing unit (which could be wireless). In fact, the control functions and display could even performed by an iPod or smartphone. With the iPod you could select the reticle, input ballistics data (Velocity, Bullet BC, Wind direction), and select the magnification level. (Fitting longer focal-length lenses would allow higher magnification than the Digital Hunters’ 2.5-16.5X.) And with a finger-tap on the screen you can record the entire match you are shooting. When mass-produced, such a unit could be sold for considerably less than the $1199.00 price of the Elcan Digital Hunter, as the iPod does the processing and replaces most of the hardware.
Many shooters using the 6mmBR case or a 6BR Improved (6 BRX, Dasher), automatically assume they should be shooting the heavier 105-108gr bullet designs because these offer the “best” ballistic coefficient attainable with a bullet that can work in an 8-twist barrel.
However, if you are shooting a 6BR at medium ranges, say 250 to 400 yards, you should seriously consider trying the 90-95 grain class of bullets, which includes the Berger 90gr Match Target BT, the Lapua 90gr Scenar, the Berger 95gr Match Target VLD, and the Sierra 95gr MatchKing.
First, you may find that, in your barrel, the 90-95 grainers are easier to tune in terms of seating depth, and they may offer somewhat better raw accuracy — yielding smaller groups than the heavier bullets. But remember — each gun/barrel is different.
Second, another advantage of the 90-95s is that you can fill the case fuller with the Varget/RL-15 class of powders (with appropriate throats). You can use more powder and therefore get closer to an optimal 100% case fill. With a 95gr VLD seated long we were able to get virtually 100% fill with a slow lot of Varget. Don’t try that with your 105s!
Lighter Bullets Offer More Speed in a 6BR
You’ll find that, in a standard 6mmBR rifle, you can drive the 90-95 grainers considerably faster than the 105-108 grain bullets at equivalent pressures. In an Eliseo R5 Tubegun, with Broughton 27.5″ 5C barrel, we were able to push the 95gr VLDs a full 160 fps faster than the 108s. This means that the true ballistics of the 90-95s rival that of the heavy bullets — at medium ranges.
We were able to drive the 90-grainers and the 95gr VLDs comfortably and very accurately at 3050 fps, whereas we maxed out at about 2890 fps with the 105gr and 108gr Bergers. At 300 yards, the 95gr bullet’s speed advantage compensates, in large part, for any BC shortfall compared to heavier bullets. In fact, in our rifle, the 95gr VLD actually shows less wind drift at 300 yards than either the Berger 105 Match Target BT or the Berger 108 Match Target BT. See chart.
Here’s data from JBM Ballistics, using G7 Coefficients (500′ alt, 70° temp):
LESSON: Don’t always assume that the heavier bullet has superior ballistics. You have to test, find the accuracy nodes for each bullet in your gun, and run the ballistics for the velocities you can actually achieve with good accuracy. As above, you may be surprised. In our Eliseo Tubegun, the 90-grainers shot tighter than 105s and we gave up little, if anything, in wind drift at 300 yards.
Great Accuracy from 90s and 95s in 6mmBR Tubeguns
In our Broughton-barreled Tubegun, the most accurate bullet so far has been the 90gr Lapua Scenar. In a Savage 6BR with 3-groove PacNor Barrel the Berger 95gr VLD has been ultra-accurate. But we really want to try the 95gr Sierra MK as well. Forum member Randy (aka “InfantryTrophy”) has been shooting the 95gr SMK with great success, and impressive accuracy. Here is his report: “The 95 SMK shoots great. I have not had the opportunity to shoot the 95s at 200 or 300 yards, but I can’t think of anything better to use. This is my first 5-round group fired after about 15 break-in rounds. The load is 29.5 grains of Reloder 15 with SMK 95. The gun is an Eliseo R5 with Pierce action and Broughton 27″ barrel. Shown below is a 5-shot, 100-yard group shot at 100 yards on MR31 target with iron sights, from rest.” Randy measured his group at 0.214″. It looks a bit bigger than that to us, but it is still impressive:
Werner Mehl, the engineering genius behind Kurzzeitmesstechnik (Kurzzeit), a German technology company, has come up with another spectacular ultra-slow-motion video. Werner has developed some of the most advanced video equipment in the world, allowing him to film bullets in flight with frame rates up to 1,000,000 frames per second. That’s not a misprint — some of the Kurzzeit video cameras can record at ONE MILLION frames per second, though typical Kurzzeit “high-speed” videos might be shot at 200,000 or 250,000 frames per second.
This 10-minute video was specially prepared by Werner for the 2009 SHOT Show. A masterpiece of high-speed movie-making, Werner’s video displays an amazing array of projectiles and targets. You can see bullets hitting armored and non-armored targets, bullets ripping through ballistic gelatin, bullets shattering glass, and even shotgun pellets striking rifle bullets in mid-air. Look for the effect of hollow points as they pass through the ballistic gelatin, and at the 4:26 mark you can see an airgun pellet slice though a paper target.
High-Tech Equipment from Kurzzeit
In addition to producing high-speed video equipment, Kurzzeit builds the PVM-21, one of the most advanced consumer chronographs on the market. The “all-infrared, all the time” PVM-21 works in any lighting conditions, including total darkness. It employs two banks of infrared sensors (front and back — the black boxes in right photo). These are aligned vertically and placed 8″ apart (left to right.) That gives you a huge 4.5″ x 8″ sensor area to register shots. We’ve worked with some other chronographs where the practical “sweet spot” for reliable results was just 2″ x 2″, when using an air rifle. The PVM-21’s large sensor area makes it easy to align your rifle, and you don’t get errors if your shot is just a little off-center.
The PVM-21 can hook up directly to a lap-top computer. That way you can record all your shot velocity data directly into a spreadsheet. The PVM 21’s large sensor area and software interface make the PVM one of this Editor’s favorite chronos, along with the classic Oehler model 35P. In the USA, the Kurzzeit PVM-21 is sold by Neconos.com. The $749.95 price includes sensor unit (with infrared), processing/display unit, infrared remote control, and software. It’s an impressive package — we just wish Werner would upgrade the display unit to include a rechargeable 12V DC battery. Right now you need to use an inline 120V AC to 12V DC transformer, or carry a separate 12V battery. I personally prefer to use a 3.5″x1.5″ rechargeable 12V battery rather than a 120v transformer and extension cords.
Many of our readers are now using smart-phones for ballistic calculations. Now there is a new App for the iPhone which makes mildot target ranging simple and easy. Mil-Dot Rangefinder 2.0 does all the math for you. Just input the size of the target, and the program calculates range instantly, in yards and meters. The standard edition costs just $1.99 while the “Pro” version is $9.99. We think that, if you’re going to really use this program in the field, it’s well worth paying ten bucks for the Pro version. The Pro edition gives you a full-featured ballistics calculator with windage/elevation corrections. That calculator alone is worth the extra money, and the Pro version offers many other features, which are listed below:
Target ranging (yards and meters)
US Army and USMC mil-dot reticles
Target Info display
Advanced ballistics calculator
Fast windspeed/direction adjustment
Range card (ballistics chart)
Point of impact indicator
Bullet drop compensator
Windage/elevation corrections
Time to target
Shot energy/velocity at target
Multiple Ballistic Profiles
This is a very powerful program. We suspect it will take most users a few days before they really understand all its functions and options. To see a more detailed demonstration of the Mil-Dot Rangefinder App, click on the YouTube video below. There’s no voice-over, so the video can be hard to follow. But at least the video showcases the flexibility of the program and the wide variety of functions it offers. Credit The Firearm Blog for spotlighting this useful App.
