New Open Tip bullets and factory-loaded cartridges by Lapua

New Open Tip bullets and factory-loaded cartridges by Lapua

For 2021, Lapua offers new Open Tip (OT) bullets and factory-loaded cartridges for target and hunting practice: Introducing the 8 mm OT bullet and 8×57 IS OT cartridge, and the 9.3mm OT bullet and 9.3×62 OT cartridge.

The 8×57 IS has earned a strong hunting reputation in recent years, but is now taking a step in the target shooting direction. Lapua Sales Manager, Erkki Seikkula, explains the thought process behind our new 8mm 7,8 g/ 120 grain OT bullet:

“We designed an easy and softly firing bullet that meets Lapua’s strict accuracy requirements. The precision of this bullet offers shooters the opportunity to practice with the same rifle that they hunt with. For avid hunters that enjoy target competitions, the performance of this projectile can really make a difference.”

A notable advantage of the bullet and the factory-loaded cartridge is that the bullet’s point of impact coincides with the Lapua Naturalis, making both products ideal for hunting practice.

The 9.3×62 has traditionally been used only with big game hunting in mind. Requirements have changed with time and today this rifle cartridge needs a bullet that offers a more diverse use of the caliber amongst hunters. Lapua has answered this demand and developed the world’s most accurate Open Tip bullet for this caliber, which extends its use to a diverse set of options from practice shooting to small predator hunting.

“The 9.3mm 12.0 g / 185 grain Open Tip bullet is available as a reloading bullet for home loaders, yet we also offer it as a factory-loaded cartridge for anyone for whom accuracy and performance matter when choosing a cartridge. Also here, the impact point of resembles that of the Naturalis bullet, making this the ultimate round for hunters training for big game hunts”, Seikkula says.

As with all Lapua products, ballistic data and trajectory information will be published on our website, with load data available by Vihtavuori Powders.

The new bullets and cartridges will be available in the beginning of 2021.

New Lapua Brass Cartridge Cases for 2021


Lapua, world-renowned for producing the finest cartridge cases and ammunition products, is happy to announce the addition of 6.5 PRC, .284 Winchester, .300 Winchester Magnum, and .300 PRC cartridge cases to our 2021 product offering. Our new Lapua brass offerings for 2021 display our continued commitment to the precision shooting disciplines which are popular on a global scale.

New Lapua brass cartridge cases

The new Lapua 6.5 and .300 PRC cartridge cases provide competitive shooters, hunters and accuracy enthusiasts a premium selection for precision hand loads, an option that’s been missing from the market since the PRC’s inception.

The 6.5 PRC case

Although the 6.5 Precision Rifle Cartridge (or PRC for short) was originally designed for long range hunting, the 6.5 PRC is still an excellent cartridge for both long range sport shooting and hunting. Its increased case capacity enables velocities up to 80 m/s (262 fps) faster than the 6.5 Creedmoor or 6,5×55 SE. By design, the cartridge features a longer throat enabling the use of today’s popular, high ballistic coefficient (BC) projectiles for long-range competitions. The 6.5 PRC case is a good match with relatively slow burning powder types. It is a great choice for heavy bullets, exceeding even 9,7 g / 150 grains with excellent retained energy and terminal performance for mid-sized and large game.

The .300 PRC case

The .300 PRC was designed for extreme long range shooting with heavy bullets featuring high ballistic coefficients. Its superior ballistics and beltless case configuration represent modern
case design that supports the use of modern long and high BC bullets. With its ability to load heavier bullets, the performance of the .300 PRC exceeds the .300 Winchester Magnum and
many other .30 Magnums on the market. The .300 PRC is also an superb choice in open and large hunting fields for long distance hunting of mid-to-large sized game with bullet
weights exceeding 15,8 g / 245 grains.

The .284 Winchester case

The .284 Winchester cartridge has experienced a recent resurgence in F-Class competition, where shooters compete to distances out to 1,000 m/yd. Members of the US Rifle Team, which Lapua sponsors, will enjoy having cases readily available in this classic cartridge. The .284 Winchester’s rebated rim design enables a larger powder column, yet easily functions through medium length actions making it desirable for custom rifles. Its accuracy potential and high muzzle velocity is also recognized in hunting fields where this cartridge performs nicely on a very wide scale.

The .300 Winchester Magnum case

The .300 Winchester Magnum has been a staple within the firearms industry, widely used by hunters, target shooters, military and law enforcement agencies around the globe since its development in the early 60’s. It is still used for competitive target shooting, hunting, and Mil/LE platforms to-date. It delivers excellent long range performance with a wide range of bullet weights from 165 to 200 grains and more. The .300 Winchester Magnum has a great reputation as a .30 caliber magnum hunting cartridge in Europe and North America. Lapua’s .300 Win. Mag case will be a great addition to our line, especially with the huge bullet selection available for sport shooting and hunting for this caliber and all major rifle manufacturers chamber their rifles for it.

All new Lapua cases will be available for home loaders in spring of 2021.

Lapua Ballistics tips: The benefits of 6DOF

Lapua Ballistics tips: The benefits of 6DOF

(For the previous Lapua Ballistics tips go to the Lapua Ballistics page)

As most Lapua Ballistics users already know, Lapua Ballistics applies the 6DOF calculation to model flight paths for Lapua projectiles. 6DOF is also the calculation model used by Lapua Product Development. So what are the advantages of 6DOF, and what does it mean for a shooter requiring accuracy?

First, let’s take a look at some other means of modelling flight paths:

The 3DOF point-mass solution

The 3DOF calculation model considers only the drag coefficient, i.e. the Cd factor. Using 3DOF doesn’t require a large computing capacity. As the name implies, there are three degrees of freedom, i.e. translational components tracked in the equation: moving forward/backward; moving left/right; and moving up/down. 3DOF calculation doesn’t take any stance on the attitude (the orientation of the projectile relative to the direction of motion) or stability of the bullet, and has a very straight-forward and simple approach to crosswind. This means that the 3DOF model calculates the position of the bullet as a function of time reasonably correctly as long as the flight is stable. In windy or changing conditions, however, this model is not the most reliable.

The modified point-mass solution

The modified point-mass calculation (sometimes referred to as 4DOF) is more advanced than the 3D model, as the calculation includes three translational degrees of freedom and one rotational degree of freedom (spinning). The aerodynamic model includes also e.g. the contribution of lift force. These are some of the same forces that the 6DOF model calculates, however the point-mass model applies a simplified calculation which does not take into account the actual attitude of the bullet, but merely includes an algebraic approximation for the attitude (pitch/yaw angles) of the projectile. Due to some simplifications involved the model is not able to give information concerning the flight stability.

Why 6DOF?

The above mentioned calculation solutions are obviously usable for trajectory calculation. So the question is, what does the Lapua Ballistics 6DOF solution offer?

The easy answer is: the most accurate results. As with the modified point-mass model, the 6DOF calculation includes three translational degrees of freedom and three rotational degrees of freedom which give the position and attitude as a function of time. Simplified, 6DOF tracks both the pitch, yaw and roll as well as the up/down, left/right and forwards/backwards movement of the bullet.
The big difference to the other calculation models is that the 6DOF models the actual trajectory path of the projectile at all times during flight, instead of just calculating points on the trajectory curve. The stability properties of the bullet are obtained during the trajectory integration since all the rotational degrees of freedom are present in simulations. Also, the stability analysis of the Lapua ballistics app is more advanced than most other calculators, as it considers both dynamic (Sd) and gyroscopic (Sg) stability factors, not only the latter as many other ballistic calculators do. The Sd is especially important in long range shooting for analyzing the transonic stability of the bullet.

But how can the Lapua Ballistics app utilize 6DOF? It is after all a very complicated mass of data, something a mobile phone would not be able to calculate.

The explanation lies in the background information of the app data. Every 6DOF-calculation is based on an aerodynamic values table that is calculated for every Lapua bullet. The table includes several aerodynamic coefficients and bullet specifics: Drag coefficient derived from Doppler radar data, Normal force coefficient slope, pitching moment coefficient slope, roll damping moment coefficient, two stability derivate, Magnus force coefficient slope and Magnus force moment. All those coefficients must be functions of the Mach number.

These calculated values are taken into account for every Lapua bullet in the Lapua Ballistics app. This is also why we can’t provide the same level of accuracy for other bullets; utilizing 6DOF requires this background data.

Accuracy comes down to not only data, but to weather, equipment, mental preparedness and so on.  The Lapua Ballistics app gives you the best data to take that perfect shot. The rest is up to you.

Ballistics App Tips: The Coriolis effect

TIP: The Coriolis effect – what is Coriolis, and how does it affect shooting?

The Coriolis Effect describes the pattern of deflection taken by objects not firmly connected to the ground as they travel long distances around the Earth. The Coriolis Effect is caused by the fact that different parts of the Earth rotate at different speeds, i.e. the rotational speed is higher at the Equator compared to the poles.

In shooting, the Coriolis Effect means in practice that the deviation of the trajectory of the bullet, i.e. the curvature, arises from the difference in rotational speed between the shooter and the target. Put simply, due to the rotational motion of the Earth, the target location moves at a different speed than the firing point during the flight of the bullet. This speed difference is affected by the location and direction of the firing point on the Earth, the firing distance, and the flight time of the bullet. The Earth rotates counterclockwise (as seen from the north), that is, from west to east.

When shooting in the northern direction near the North Pole, the circumferential speed of the target is lower than the circumferential speed of the shooter standing south of the target, whereby the distance from the shooter to the axis of rotation of the Earth is greater than the distance of the target to the axis of rotation. Thus during the bullet’s flight, the target has turned less to the right compared to the shooter, and the bullet misses the target flying past it to the right. When shooting in the southern direction near the North Pole, the circumferential speed of the target is higher than the circumferential speed of the shooter. In this situation during the projectile’s flight, the target has turned more to the left than the shooter and the bullet again misses the target to the right.

At what shooting distances does Coriolis have an effect?

The effect of the Coriolis phenomenon can already be seen on medium firing distances, but it becomes an essential variable for the hit with shooting distances of 1,000 m/yds and beyond.
The Coriolis phenomenon affects the flight of a bullet in the Northern Hemisphere so that when firing north or south, the bullet sways to the right and in the Southern Hemisphere to the left. The more your firing line is in the east-west direction, the less the effect of the Coriolis.

The magnitude of the deviation depends on the location latitude and the flight time of the bullet. The maximum deviation is at the poles and the smallest at the Equator, because the difference in rotational speed between the shooter and the target is at maximum at the poles and zero when firing symmetrically over the Equator.

The Eötvös Effect

When shooting a bullet to the east or west, the Eötvös Effect also affects the flight. When a bullet is fired in the direction of rotation of the earth, i.e. to the east, the shots hit high. If the bullet is shot west, the shots hit low. The reason behind it is that when you’re firing east, in the direction of the Earth’s rotation, the target has time to move during the flight time below what the aiming point was, so the hit is at the top. When shooting west against the direction of the Earth’s rotation, the target has time to move higher than the aiming point during the flight, so the bullet hits low. The more your firing line is in the north-south direction, the less the effect of the Eötvos phenomenon.

Often the Eötvös Effect is considered to be part of the Coriolis phenomenon, but it is in fact its own separate phenomenon. The Eötvös Effect is at its strongest at the Equator and at zero at the poles. The deviation caused by Coriolis and Eötvös effects are around +/- 10 cm / 3.9’’ at a distance of 1,000 m/yds.

Using Coriolis calculation in Lapua Ballistics

  • From the menu in the upper left corner of the screen, select “Manage Rifle / Cartridge Data” and from the drop-down menu, select the rifle / cartridge for which you want to enable Coriolis calculation. Scroll down to the Sight-In settings and set “Sight-In Coriolis” to On.
  • In the Sight-In Latitude window, set the latitude at which you have done the sighting-in, and in the window next to it, set the direction in which you’ve fired when sighting-in.You can easily check the latitude with Lapua Ballistics when you are at your shooting location, or from Google Maps by clicking on the location where you have done the sighting-in. Enter the value in the style of xx.xx.  From the same Google Maps view, you can also estimate the cardinal direction in degrees of your sight-in. North is 0˚, East is 90˚, South is 180˚ and West is 270˚. Naturally, you will get the exact value for the sight-in direction with a compass when you are at your firing point.Next, tap Save.

Coriolis in Calculator view

Now that the basic settings are in order, you can use the app’s Coriolis calculation by swiping to the third upper window of the Calculator view.

  • By tapping the red icon in the middle of the screen, the system automatically sets the latitude you are currently at. You can also set the latitude manually by typing or selecting it from the scroller.
  • Next, set the shooting direction degrees in the top right corner of the upper window, or select the value by rotating the red arrow on the circle.
  • Once you have set all the other values ​​related to the calculation, swipe back to the first upper window and enter the shooting distance and wind values.
  • The app now automatically takes into account both the Coriolis Effect and the Eötvös Effect in the calculation.

However, also keep in mind that Spin drift also affects lateral movement at long distances and should also definitely be considered when shooting long distances. Spin drift is its own phenomenon independent of the Coriolis, which Lapua Ballistics takes into account in the calculation when you have it set to ‘On’ in the basic settings menu.

Ballistics app tips: Sight-In POI

We are kicking off a brand new series on our website: Lapua Ballistics app tips! Get the most out of our free of charge ballistics calculator by following our tips which we will be sharing all through year 2020.

Tips in the series:

Utilizing Point Blank Range and V0 or Muzzle velocity calculation

NEW: The Sight-In POI feature

Coming up next: Coriolis effect, Benefits of 6 DOF calculation and Trajectory calculation for bullets and cartridges

EASY APP SETUP: If you haven’t tried our app yet, download it and check out our guide for easy setup!

TIP: The Sight-In POI feature – how to use several cartridges in the same firearm

Sight-In POI is a tool that can be utilized when you need to use several different types of cartridges in the same firearm without changing the basic sight-in setup of the scope. Knowledge of how different types of cartridges behave in your own rifle extends, for instance, the practice season well into the hunting season, and it means you can use the appropriate ammunition in any situation without having to sight-in the firearm again. When using the Sight-In POI feature, several different cartridge variations can be built around the sight-in settings of the rifle’s primary cartridge, depending on what cartridge needs you have.

How to use the Sight-In POI feature in Lapua Ballistics:

  • Make sure you have set the reticle click units for your scope correctly in the app.
  • Select the rifle profile you want to use as your primary profile and primary cartridge and sight-in the rifle to suit it.
  • Copy the primary profile under another name (eg. Cartridge 2), select your preferred 2nd cartridge and set the correct muzzle velocity for it
  • Test shoot the 2nd cartridge at your preferred distance without changing the scope settings.
  • After test shooting, measure the distance (height and width) between the hits of the shot group and the point of aim, and calculate how many scope clicks this difference corresponds to.
  • Alternatively, you can determine the corrections by re-sighting the rifle with the 2nd cartridge. When choosing this option we recommend zeroing the turrets for the primary profile. Next, carefully calculate the needed number of clicks for Cartridge 2. Once you have the number of clicks add them to the Sight-In POI Elevation and Windage windows of your Cartridge 2 profile.
  • Enter a positive number if the 2nd cartridge hits above or to the right of the point of aim, and a negative number if it hits below or to the left.
  • Similarly, you can also set the click corrections for your 3rd cartridge etc.

EXAMPLE: Sighting in a FMJ cartridge

You want to use the Lapua Naturalis cartridge with the N558 bullet as the primary profile and create a parallel profile in the same rifle using the 8g FMJ (S374) bullet. àCopy the Naturalis profile and start updating the copied profile with the FMJ cartridge data. When sighting-in, the FMJ cartridge shot group hits the target 4cm above the point of aim.

  • Select Manage Rifle / Cartridge Data from the menu, activate the Sight-In POI feature, enter the value 4 in the Elevation POI Up column (in the example case, the sight-in distance is 100m and the scope click setting 1cm / 100m). Save the profile after changing the settings.
  • In the Calculator view for a shooting distance of 100m, the needed correction indicated by the calculator should now be ↓ 4 clicks, and in the crosshair view, the point of impact for the shot group should be slightly above the center grid.

Good to know about the Sight–in poi feature

  • When using the Sight-In POI feature, the sight-in distances don’t have to be the same for all cartridges (for the sake of clarity, the same distance was used in the previous example).
  • The PBR sight-in presented in the previous Lapua Ballistics Tip can also be entered into the rifle profile with the Sight-In POI feature, example: The optimal sight-in distance for a cartridge is 170m but you only have a 100m shooting range. Sight-in the rifle at 100m so that the hits are approx. 5 cm above the point of aim. Enter a sight-in distance of 100m in the rifle profile and 5 clicks in the Sight-In POI Elevation window.
  • If the scope doesn’t have resettable turrets, mark the zero points of the primary cartridge with something, eg. a sticker.
  • When the Sight-In POI feature is activated in the profile, it is easiest to make sight corrections using the clicks no matter what the shooting distance. Example using the previously created 8g FMJ bullet profile: When shooting at 250m, an increase of 6 clicks is required.
  • The Sight-In POI feature is available for Lapua products and Custom profiles.
