Many folks struggle when they sight-in a scoped rifle for the first time. A very common mistake is clicking the turrets in the wrong direction. That’s frustrating and it wastes ammo. Another common problem occurs when people sight-in at a distance other than 100 yards. People sometimes struggle to figure out how many clicks they need to correct point of impact if they’re zeroing at 200, 250, or 300 yards.
To make the sight-in process more fool-proof, AccuScope has released two handy Apps for smart phone users. Whether used for initial sight-in or in-the-field adjustments, these smartphone Apps can get you zeroed quickly and reliably.
Using the Apps is easy. First, boresight the gun to get on paper. After the gun is fouled-in (so it is shooting normally) shoot a carefully aimed 3-shot group. Then go to the target and measure the vertical and horizontal distance from the 3-shot group center to your aiming point. Input those numbers into the App, along with your sight-in distance (from muzzle to target). The App then calculates exactly how many elevation and/or windage clicks you must crank into your scope to move point-of-impact to point of aim. Put in the specified clicks and then take a fourth shot to confirm your zero. The fourth shot should impact right on your point of aim (within the limits of the gun’s inherent accuracy.)
Given Murphy’s Law, a shooter can still mess things up if he inputs left clicks when the App calls for right clicks, or inputs down clicks when he needs up clicks. But as long as you look at the “R/L” and “Up/Down” labels on your turrets before spinning the knobs, you shouldn’t have any problems.
AccuScope is available in two versions, Standard and Premium. The $4.99 Standard version works for 1/4 MOA-click-value scopes. The $9.99 Premium version works with all scopes and any click values. The Premium version works with 1/8 MOA clicks, 1/4 MOA clicks, Metric clicks, or Milrad segment click values. So, if you have a scope with 1/8 MOA clicks, you’ll need the Premium version.

Editor’s Comment: Does this App really provide a solution you can’t figure out yourself with simple arithmetic? No, but some math-challenged guys may find that the App prevents errors. Additionally, following the step-by-step process used by the App will probably help some shooters avoid confusion, and avoid wasting ammo clicking in the wrong directions.
Note however, that there is an even simpler way to zero, if you have a very solid front and rear rest that will hold the gun absolutely steady while you click. After bore-sighting, fire a couple rounds (with the same point of aim). Then place the rifle so the center of the cross-hairs is exactly on your original point of aim. Next, without disturbing the gun in any way, dial your turrets so that the center of the cross-hair moves over the center of your group. That’s it. You’re now zeroed (though you may want to repeat the process for confirmation). Again, this only works if the gun doesn’t shift one bit when you’re clicking. Having a helper steady the gun as you click the turrets will make this “no-math” method work more effectively.

Here’s good news for Applied Ballistics Mobile App users with Samsung smart-phones, running the latest OS. Bryan Litz reports: “For those who were experiencing problems with the Applied Ballistics Mobile app on the new Galaxy S4 devices, I’m happy to announce that the problem has been resolved. App users should have the update already — once you have a network connection, the App will check for the update, which will be pushed out to the device.”
If you use a balance-beam scale to weigh powder and reloading components, here’s a clever way to magnify the view of the beam tip. Of course you can use an old-fashioned magnifying glass, clamped in place, to upsize the view. But now there’s a parallax-free, electronic solution that works for anyone with an iPhone or Android OS smartphone.
Forum member Allan E. (aka “1066”) discovered that he could use the camera on his smartphone to display and magnify the image of a balance-beam tip. This works via a Magnifying Glass App you can download for free. Just turn on the smartphone, activate the Magnifying Glass App and zoom-in to suit your preference. Alan explains: “This saves those tired eyes. It’s much more accurate because there’s no parallax — the lens is directly in line with the pointer so we can see [the pointer] off the screen from any angle. It’s a much clearer view, and it costs nothing.”
You’ll need to fabricate some kind of stand or clamp for the phone. Allan created a smartphone mount with a bit of wire, rubber bands, and a bullet box. You can see the system working in the video below. (The video starts by showing a webcam + laptop balance-beam monitor system. The Smartphone system demo begins at the 1:30″ time-mark.)
Magnifying Glass Apps for iPhones and Android Phones
There are numerous ‘magnifying glass’ programs for Apple and Android smartphones that use the built-in camera. Most include a zoom function and auto-focus. You might try a couple different Apps and see which works best for you. Some perform better in low light, while others resolve better. All of the following have 4-star or better user ratings:
Leupold has launched a redesigned website with more intuitive navigation and many new features. Products are now organized into four main categories: Hunting and Shooting, Tactical, Observation, and Golf. Drop-down menus under each heading shorten the time for users to locate detailed info on specific products. An enhanced Leupold Scope Finder feature allows users to filter the entire catalog down through six categories:
Type of firearm
Price range
Maximum magnification range
Objective size range
Choice of Bullet Drop Compensation reticles
Illuminated or non-illuminated
With the new Scope Finder, a Comparison Tool lets users review scopes side-by-side. Key scope specs appear in adjacent columns for easy comparison shopping. Mike Slack, Leupold’s Sr. manager of advertising and communications notes: “The site’s new Scope Finder tool should help consumers quickly find the right product for their needs.”
New Leupold Site Works Well with Tablets and Smartphones
Leupold designed its new website to be fast to load and quick to navigate for users with smartphones and tablets. iPhone and Android phone users will note that the navigation is much simpler and most function screens can be utilized without excessive scrolling.

The popular BulletFlight Ballistics Program, is now available for Android OS smart phones and mobile devices. BulletFlight (from Knights Armament) has emerged over the past couple of years as one of the very best balllistics programs for iPhones and iPods. And now Android device users can enjoy the same functionality and features.
BulletFlight Android OS software comes in three different versions, all available through the Android Market. BulletFlight L1 (Level 1, $3.99) is a fast-running ballistics App with a host of features, including: user-selectable BC models (G1, G7, G8 etc.); output in inches, cm, MOA, Mils, and scope clicks; 360° wind drift calculation. BulletFlight includes a large database of bullet types (with weights, BCs etc.)
BulletFlight L2 (Level-2, $11.99) adds a full calculation screen where you may enter exact range and atmospheric details. The Level-2 version can also generate range-cards, perform cosine-angle calculations, handle mil-dot range estimations, and calculate impact energy, velocity, and flight time. What’s more, Level-2 offers GPS functionality so you can geo-locate your position, and/or download local weather information. The $11.99 L2 software package is what we recommend for most users.

Level M is Ideal for Ultra-Long-Range Shooting
Priced at $29.99, BulletFlight Level-M (Military) version further adds the ability to calculate an actual BC based on bullet drop, two velocities, or flight time. This can be useful if you make your own bullets, do extensive experimental work, or shoot at extreme long range. If you do regularly shoot beyond 1000 yards, BulletFlight Level-M is probably the best choice. The Level-M software factors bullet spin drift and Coriolis effect into the ballistics solution — making this a super-sophisticated tool. In addition, the Level-M software can calculate bullet stability based on MV, barrel twist rate, and bullet specs.
With all versions of BulletFlight, you can also create your own custom ammo profiles (with velocity, BC, bullet type), allowing you to easily output ballistic plots for multiple firearms, without having to enter the rifle/bullet profile each session.

Bryan Litz, Ballistician for Berger Bullets and author of Applied Ballistics for Long Range Shooting, has tested the latest version of the Shooter Ballistics Calculator for Android™ OS Smartphones and portable devices. This is a very sophisticated, full featured App that incorporates the latest bullet databases with Litz G7 BCs as well as a wealth of other information. It provides extremely reliable ballistics solutions at all ranges, and in all atmospheric conditions.
Bryan tells us: “The Shooter App has been improving steadily since it was first released and there are many new capabilities now. One of the cool new features is a wireless Bluetooth link to Kestrel Weather Trackers. This can automatically provide the exact atmospherics at your location.”
Bryan used the Shooter App on a trip to Wyoming: “I shot a Sako TRG42 in .338 Lapua Mag to 2400 yards with Berger’s new 300gr hybrids. The dope from the Shooter App was spot on up to 103 MOA of drop using the G7 BC of .419 for that bullet! At 2400 yards, even at 6,000 ft+ elevation, the bullet is subsonic but remained stable and tracked perfectly with the predicted trajectory from Shooter. I don’t know if the same bullet would be stable at sea level when fired at that range or not but it worked well at 6,500 feet.”
Litz Says Shooter App Offers Very Sophisticated Ballistics Solutions
Bryan thinks the Shooter App is extremely accurate: “I consulted on the solver development for Shooter so I can personally vouch for the accuracy of this program. You can set up profiles for rifles and ammo types including calibration factors for scope adjustments, temperature affects on powder burn rate / muzzle velocity, and of course G1 and G7 referenced BCs (you can define a ‘stepped’ BC for both as well). You can set preferences for units, atmospherics, station pressure or altitude, and more. It can calculate spin drift and Coriolis effect, or those features can be disabled. If your smartphone has GPS, the program can automatically populate the latitude for Coriolis calculations.”
Shooter App is just $9.99 — A Bargain Given Its Capabilities
The full-featured Shooter App sells for $9.99 in the Android Apps Marketplace. Visit the Shooter App Website to preview the program’s functions and see how the entry screens work. The App is easy to install and run. There is a also a ‘Lite’ version of SHOOTER that you can download for free.
