.338 Lapua Magnum maximum C.I.P. cartridge dimensions. All sizes in millimeters (mm).
Americans would define the shoulder angle at alpha/2 ≈ 20 degrees. The common rifling twist rate for this cartridge is 254 mm (1 in 10 in), 6 grooves, Ø lands = 8.38 mm, Ø grooves = 8.58 mm, land width = 2.79 mm and the primer type is large rifle magnum.
The Lapua Magnum cartridge offers several advantages over other calibers when it comes to long-range shooting. Its high ballistic coefficient means that it retains its velocity and energy over long distances. This results in a flatter trajectory and less bullet drop, making it easier to target at long ranges. Additionally, the cartridge has excellent stopping power due to its large bullet size and high muzzle energy – making it a sniper’s choice for hunting large game or taking out targets at extreme ranges. The Lapua does hold up well compared to the 338 Winchester mag and magnum.
Parent case, case type, bullet diameter, land diameter, neck diameter, shoulder diameter, base diameter, rim diameter, rim thickness, case length, overall length, case capacity, rifling twist, primer type, and maximum pressure all play critical roles in the performance of 3-38 Lapua’s calibers and their various iterations, such as the .338, lapua, magnum 3-38 lapua, 338 lm, magnum gun, 338 lapua magnum, winchester 338 mag, .338 lapua, lapua canada, 3-38 lapua vs 308, 338 magnum, lapua magnum 3-38, and 3-38 Winchester mag.
In the service history, some of the frequently asked questions or FAQs often revolve around the topic of firearms. One such question pertains to the comparison between Lapua and 50 cal. “Is 338 Lapua stronger than 50 cal?” is an inquiry that often finds its way to the discussion box.

In the realm of sniper rifles, the Lapua often takes the lead. The loaded .338 cartridge is quite advanced and offers more than just firepower. With the diameter being 14.93 mm (0.588 in) in the rim and the length being 93.5 mm (3.68 in), its dimensions allow for better penetration. Surprisingly, this cartridge can penetrate better-than-standard military body armor at ranges stretching up to 1,000 metres (1,090 yd), and has established itself as a noteworthy adversary with a maximum effective range of about 1,750 metres (1,910 yd). This performance is maintained with C.I.P. conforming ammunition in sea level conditions. When it comes to muzzle velocities, they can vary from 880 to 915 m/s (2,890 to 3,000 ft/s) because of the influence of factors such as barrel length, seating depth, and powder charge.
When dissecting the advantages of the Lapua Magnum cartridge, several factors come into play. This is especially evident when making comparisons with other cartridges on grounds of long-range shooting. Firstly, it boasts of a high ballistic coefficient, which enables it to retain its velocity and energy over extended distances. This results in a flatter trajectory and reduced bullet drop, making it easier to line up shots at long-distance targets. Secondly, the cartridge displays excellent stopping power because of its large bullet size and high muzzle energy. These characteristics establish it as an ideal choice for hunting large game or taking out long-distance targets.
Why Choose 338 Lapua Ammo?
In an attempt to extract the most out of your Lapua ammo, you’ll require a rifle specifically designed to handle its substantial power and accuracy. There are several guns available in the market designed for this very purpose, and choosing the correct one is the first step towards mastering long-range action.
Best Rifles for 338 Lapua Ammo
If you are to fully grasp the performance of Lapua ammo, understanding its ballistics is crucial. The muzzle velocity can range anywhere between 2,800 to 3,000 feet per second (fps). This high velocity gives the bullet a flat trajectory and minimal drop at extended distances. On the other hand, the muzzle energy can span from 4,000 to 5,000 foot-pounds (ft-lbs), depending upon the specific load. This high energy imparts the cartridge noticeable stopping power, making it formidable against large game and targets at extended ranges.

In terms of trajectory, Lapua ammo’s path is relatively flat, courtesy of its high muzzle velocity and ballistic coefficient. At 1,000 yards, for instance, the bullet drop can be as meager as 20 inches. This characteristic makes this ammo particularly efficient for hitting targets at extreme ranges.
Ultimately, it all boils down to the shooter’s skill and practice when engaging in long-range shooting with Lapua ammo. Wind drift is a significant factor to be considered here. To compensate for wind drift, the shooter must comprehend the wind direction and speed and adjust the aim accordingly. Additionally, bullet drop must also be factored in. One must understand the trajectory of their specific load and adjust their aim to compensate for bullet drop. Achieving accurate shots at longer ranges also involves having a stable shooting position. This could include using a bipod, shooting from a benchrest, or using a shooting bag to support the rifle.
The major building blocks of a bullet, including the parent case, case type, bullet diameter, neck diameter, shoulder diameter, base diameter and upwards, together, they make for the grandeur-commanding Lapua.
The trajectory of Lapua ammo is relatively flat, thanks to its high muzzle velocity and ballistic coefficient. At 1,000 yards, the bullet drop of Lapua ammo can be as little as 20 inches, making it easier to hit targets at extreme ranges.
The recoil of Lapua ammo can be quite significant, especially when firing from a lightweight rifle. To manage recoil, many shooters use a muzzle brake or a suppressor to reduce the felt recoil.
Long-Range Shooting with .338 Lapua Ammo
Long-range shooting with Lapua ammo requires skill and practice, but it can be extremely rewarding. Here are some tips for long-range shooting with Lapua ammo:
Wind drift can be a significant factor when shooting at long ranges. To compensate for wind drift, you need to understand the wind direction and speed and adjust your aim accordingly.
Bullet drop is another factor to consider when shooting at long ranges. You need to understand the trajectory of your specific load and adjust your aim to compensate for bullet drop.
