Lapua offers a sophisticated FREE Ballistics App for iOS and Android smartphones and mobile devices. This state-of-the-art App has many great features — much more than you’d expect for a free App. If you do much shooting past 300 yards, or use a wide variety of bullets and/or cartridge types, we recommend you download the App and give it a try. This article, written by a Lapua technician, explains how to use the App. This article is definitely worth reading — there are many important concepts and procedures discussed here that apply to all Ballistics calculators, not just the Lapua App. For more details, read the Lapua Ballistics App User Manual.

The Lapua Ballistics App is available for Android and iOS smart phones and mobile devices free of charge. For more info, visit www.lapua.com/lapuaballisticsapp.

Lapua Ballistics App Basics — How to Get Started

Article by Matti Paananen
As smartphones and tablets are constantly developed, ballistic software and Apps are also improving, and with their help our ability to hit targets can improve significantly. This is a short introduction on why and how to use a ballistic calculator, namely the Lapua Ballistics App, and a few pointers that will help you use the App effectively.

Ballistics software and Apps are designed to help shooters and hunters make calculations to hit distant targets or take down game in the field by offering ballistic solutions. Lapua Ballistics is the first App utilizing the 6DOF calculation model.

Toying around with ballistics apps is always fun, but effective use of ballistic software requires general understanding of how they work. The App gets information from the user and by using mathematical formulas it provides the solution that will give the user a solid starting point to hit the target.

However, it is also important to remember that the App can’t think — it only calculates a solution based on your parameters. You will not know the error until you have already fired the shot.

1. SET UP YOUR SCOPE RETICLE AND RIFLE
Scope manufactures use different units per click, so it’s important that you use the correct unit in the App. For example, in your scope, one click can be 0.1 mil, 1/4 MOA, [or 1/8 MOA depending on the model]. You can find this information in your scope manual and also usually from the scope turrets. Setting your scope reticle is very important, partly because if you use the wrong unit in the App, the ballistic solution will not match your scope. To set up your scope reticle in Lapua Ballistics, go to Manage Rifle / Cartridge Data –> Add Rifle Cartridge Data (or choose to edit a Rifle/Cartridge combo you’ve already set up) –> Reticle –>.

Another thing to setup in Lapua Ballistics is your scope height, i.e. Line of Sight to Bore in the Manage Rifle / Cartridge Data window. This is the distance between the center of the scope and the center of the bore. The default height is 45mm but with tactical rifles, the height can be even 70mm. So check! The height is easy to measure with a ruler. Then there’s also the twist rate of your rifle to set up — look it up in the rifle manual, it can also be stamped on the rifle barrel. The rifle twist rate is needed to calculate spin drift and bullet stability. Spin drift should be taken into account with longer distances, and it can be enabled or disabled in Lapua Ballistics.

2. SET UP YOUR BULLET CHOICE
You can add your bullet of choice from the bullet library, where you find all Lapua bullets. It is also possible to add information manually. In this case, you will need bullet weight, the ballistic coefficient BC and muzzle velocity. The Ballistic coefficient can be given in G1 or G7 values. G7 is designed for low-drag bullets with a boat tail and G1 is used for more traditional flat base bullets. Lapua on the other hand uses Doppler radar-based data to calculate a more accurate ballistic trajectory for Lapua bullets by 6DOF model. Anyway, it is good to remember that the ballistic coefficient changes with velocity, so all changes in a flight path cannot be predicted.

The following thing you will need to set up is the bullet’s actual muzzle velocity. You can reverse engineer the number based on your drop or by using a chronograph. It is good to remember that more rounds you shoot, the better average velocity you will get.

Because temperature affects muzzle velocity, it would be good to shoot velocities in different temperatures and write them down. Those notes can be used with Lapua Ballistics as it is possible to set up the powder temperature variation in the App.

3. SET UP WEATHER CONDITIONS
Lapua Ballistics has settings for temperature, air pressure, and humidity. All these affect the ballistic solution and the chance to hit the target. In a nutshell, temperature affects the powder’s burn speed and in that way the bullet velocity. Air pressure and humidity also affect bullet drag.

If you are shooting approximately on sea level, you do not need to change air pressure values, but if you are shooting or hunting in mountain areas or where there is lot of elevation difference, you might want to check the air pressure. On sea level, the atmospheric pressure is 1013 hPa. The higher you go, the less air pressure you will have and thus less bullet drag. Some like to use handheld weather and wind meters that have a function to get actual air pressure and humidity, however the Get Current Weather function in Lapua Ballistics will give you the air pressure reading from your local and most close weather station, provided that your app is allowed to use your location data.

Temperature is an important variable. To understand how velocity change in different temperatures, only way is to shoot and keep notes. Some ballistic software and apps have values for muzzle velocity in different temperatures. The user needs to input muzzle velocity in different temperatures in order to software to calculate the effect. More velocities in different temperatures the user adds, the more accurate the calculation will be.

4. SET UP A BALLISTIC SOLUTION
After we have set up our own rifle / cartridge data, there are few things that need to be taken into account when shooting: the distance to the target, the wind and our shooting skills. Distance can be measured for example with a laser rangefinder and then put in. Wind can also be measured with a wind gauge but it is important to remember that the wind in the target area can be very different from that in the shooting position. Lapua Ballistics gives a ballistic solution based on stationary wind, so in the end, the shooter’s task is to estimate how much the wind factor will be.

It’s good to remember that Lapua Ballistics is a starting point and designed to assist the shooter. Software and apps have ways of helping us adjust the sight and predict the ballistic solution but they will not replace the shooter. We still have to pull the trigger and record our range data. By keeping good range notes and with the support of good ballistic software like Lapua Ballistics, we should be able hit in all environments.

Six Great Gear Items for Shooters — All Under Twenty Bucks

cheap tricks under $20 gear

Some top-flight components for a great-shooting rifle surely aren’t cheap — like a custom action ($1200 and up). And a premium, match-grade scope could set you back two grand or more. But there are still some great items that cost under $20.00 that can benefit any gun-owner. Here are our selection of six great shooting accessories under twenty bucks. Many of these are top-selling items on Amazon. The first item, a motion-sensitive light for your gun safe, has been a big hit with our readers.

1. Amazon — Motion-Sensitive Interior Light for Gun Safes, $9.95

gun safe light vault cabinet motion sensor light motion sensing LED magnet lamp

Let there be light. Here’s a great accessory for your Gun Safe. This “smart” LED lamp turns itself on when you open the door, and off when you close the door. There’s a built-in magnet so you can easily attach the light to the inner walls or “ceiling” of your gun safe. It works, it’s handy, and it’s inexpensive — just $9.99 with free shipping for Prime members (or otherwise free shipping for $25+ orders). We bought two for our own firearms vault. This can provide 14 hours of light with three AA batteries (not included). Very versatile, these motion-sensor lamps can also be used in closets. NOTE: This item has been very popular with our readers, who have purchase six dozen already.

2. Amazon — Discovery Scope Level, $8.99 (30mm)

Optical Rifle Scope bubble level Discovery 30mm 1 inch 34mm Amazon

If you shoot long range, you need a scope level. This Discovery scope level is fully CNC-machined to close tolerances for a good fit. It is available with inner diameters to fit scopes with either 1″ or 30mm main tubes. The popular 30mm version is now on sale for just $8.99 while the 1″ model is $9.99. (That’s right, the bigger version is cheaper right now). You could easily pay $35.00 or more for a 30mm scope level. Purchasers have praised this product: 84% of verified buyers rated this four or five stars.

3. Amazon — 34 dB Noise Rating Ear Muffs, $17.45

34dB NRR 32 hearing protection earmuffs

These 34 dB NRR earmuffs provide excellent sound protection without being too heavy and bulky. At at $17.45, they are a great bargain. The lower section of the muff is trimmed for a narrower profile — that helps with rifle and shotgun stocks. The headband is adjustable and has comfortable padding. Select from ten color options: black (above), grey, pink, purple, teal, white, green, blue, red, and Coyote Brown (our favorite). These Pro For Sho Muffs have earned a 4 1/2 star consumer rating, with over 1,600 Amazon customer reviews. NOTE: These fit pretty tight. If you have a very large hat size you might want a different brand.

4. Midsouth — Lee Universal Decapping Die, $10.95

Lee Universal Decapping die

Midsouth sells the Lee Universal Decapping Die for just $10.95 (item 006-90292), a very good deal. There are many situations when you may want to remove primers from fired brass as a separate operation (prior to case sizing). For example, if your rifle brass is dirty, you may want to de-cap before sizing. Or, if you load on a progressive press, things will run much more smoothly if you decap you brass first, in a separate operation. The Lee Universal Decapping Die will work with cartridges from 17 Fireball all the way up to 45-70. However, NOTE that the decapping pin supplied with this Lee die is TOO LARGE for LAPUA 6.5×47, 6BR, 220 Russian, and Norma 6 PPC flash holes. Because the pin diameter is too large for these brass types, you must either turn down the pin, or decap with a different tool for cases with .059″ flash-holes. Otherwise, the Lee Decapping Die works well and it’s a bargain.

5. Amazon — Bore Stores Rifle Cases Starting at $14.99

Bore-Store Gun Sacks

Our take on Bore-Store Gun sleeves is simple: They work great, so buy them and use them — for ALL your valuable firearms.

These thick, synthetic-fleece sacks cushion your guns, preventing nicks and scratches. The breathable fabric wicks away moisture, and the fibers are coating with corrosion inhibitors. I personally use Bore-Stores for in-safe storage with all my guns, and I have never had one of my guns rust inside a Bore-Store, even when I lived a stone’s throw from the ocean.

Bore-Stores are offered in a wide range of sizes, so you can find something to fit everything from a Snub-nosed revolver to a 32″-barrelled 50 BMG. Rifle-size Bore Stores can be purchased for $14.99 – $23.00 from Amazon.com. For long F-Class or tactical rifles, we recommend the 10″x52″ SSG Scoped Shotgun Bag. You can also order direct from the Bore-Store manufacturer, Big Spring Enterprises, www.BoreStores.com. Big Spring will also craft custom sizes on request.

6. Midsouth — Lyman Bleacher Loading Blocks, $6.14

Max NRR 33 db ear plugs

Lyman’s new Bleacher Block stepped cartridge holders are great. Use the different levels for sorting brass. Or, migrate the brass from top to bottom as you proceed through case prep stages. Made of durable polymer, Bleacher Blocks are molded in three sizes. The smallest size (with 0.388″-diam holes) fits .223 Rem-size case heads. The middle size (with 0.485″-diam holes) fits .308 Win-size case heads. The biggest Bleacher Block has 0.565″-diameter recesses for magnum-size cases. All three cartridge block sizes hold fifty (50) rounds. Purchase any size for just $6.14 per Block at Midsouth.
