338 Lapua vs 308 Ballistics

When comparing the 338 Lapua and the 308, it’s important to consider the ballistics of each cartridge. This section will examine the trajectory, muzzle velocity, energy, and accuracy of both cartridges.


Trajectory is the bullet’s flight path to its target measured in bullet drop. Looking at the .338 Lapua vs .308 Ballistic Table, we see that the .338 Lapua has a flatter trajectory than the .308 Win. This means that the .338 Lapua will drop less over long distances, making it more accurate at longer ranges.

Muzzle Velocity

Muzzle velocity is the speed at which a bullet leaves the barrel of a firearm. The .338 Lapua has a higher muzzle velocity than the .308 Win. This means that the .338 Lapua will travel faster and maintain its velocity over longer distances, making it more effective at longer ranges.


Energy is the amount of force a bullet carries. The .338 Lapua has a higher energy than the .308 Win. This means that the .338 Lapua will hit with more force, making it more effective at taking down larger game or penetrating barriers.


Accuracy is the ability of a firearm to hit a target consistently. The .338 Lapua is more accurate than the .308 Win at longer ranges due to its flatter trajectory and higher muzzle velocity. However, the .308 Win is still accurate at shorter ranges and is a popular choice for hunting and target shooting.

338 Lapua vs 308 Recoil

When it comes to choosing between the 338 Lapua Magnum and the 308 Winchester, one of the most important factors to consider is recoil. Recoil can affect both accuracy and shooter comfort, so it’s essential to understand the differences between these two cartridges.

338 Lapua Magnum

The 338 Lapua Magnum is a powerful cartridge that can produce significant recoil. Depending on the rifle and load, recoil energy can range from 35 to 40 foot-pounds.

This can make it challenging to shoot accurately, particularly for smaller or inexperienced shooters. However, with proper technique and practice, many shooters can learn to manage the recoil of the 338 Lapua Magnum effectively.

308 Winchester

The 308 Winchester, on the other hand, has a much more modest recoil of about 20 foot-pounds of force. Most shooters will state that this recoil is manageable, and it will not bruise your shoulder after a long shooting session. The lower recoil of the 308 Winchester makes it an excellent choice for beginner shooters or those who are sensitive to recoil.

It’s worth noting that recoil can be affected by several factors, including rifle weight, stock design, and muzzle brake or suppressor use. Shooters should consider these factors when selecting a rifle for either cartridge.

Ultimately, the choice between the 338 Lapua Magnum and the 308 Winchester will come down to personal preference and intended use.

Shooters who prioritize long-range accuracy and power may prefer the 338 Lapua Magnum, despite its heavier recoil. Meanwhile, those who prioritize comfort and ease of use may opt for the 308 Winchester.

338 Lapua vs 308 Applications

Military and Law Enforcement

The .338 Lapua is widely used by military and law enforcement agencies around the world. Its long-range capabilities and accuracy make it suitable for snipers and marksmen. The .308 Win is also used by military and law enforcement agencies, but it is typically used in shorter-range engagements.

The .338 Lapua has been used in combat situations, and it has proven to be effective in neutralizing targets at long ranges. Its high muzzle velocity and energy make it capable of penetrating body armor and other barriers. The .308 Win, on the other hand, is not as effective at penetrating barriers.


The .338 Lapua is suitable for hunting big game at long ranges. Its high muzzle velocity and energy make it capable of taking down large animals such as elk and moose. The .308 Win is also suitable for hunting, but it is typically used for smaller game such as deer and antelope.

When hunting, it is important to use the appropriate ammunition for the game being hunted. Using a bullet that is too light or too heavy can result in poor performance and can be dangerous.

Long-Range Shooting

The .338 Lapua is a popular cartridge for long-range shooting competitions. Its long-range capabilities and accuracy make it a favorite among competitors. The .308 Win is also used in long-range shooting competitions, but it is typically used in shorter-range competitions.

When shooting at long ranges, it is important to use a cartridge that is capable of maintaining accuracy at long distances. Wind and other environmental factors can affect the trajectory of a bullet, so it is important to use a cartridge that is capable of compensating for these factors.


Q: Which cartridge is better for long-range shooting?

A: When it comes to long-range shooting, the .338 Lapua Magnum is generally considered superior to the .308 Winchester.

The .338 Lapua Magnum’s larger case capacity, coupled with heavier bullets, provides better retained energy and less wind drift at extended distances, making it a preferred choice for extreme long-range precision shooting.

A: While the .338 Lapua Magnum is primarily known for its long-range precision shooting and hunting capabilities, it has also found applications in military and law enforcement operations.

Its high energy, long-range effectiveness, and penetration make it suitable for certain tactical scenarios and anti-materiel use.

Additionally, some long-range shooting enthusiasts enjoy the challenge of engaging targets at extreme distances with the .338 Lapua Magnum due to its impressive ballistics.


After analyzing the technical data and use cases of both the .338 Lapua and .308 Winchester cartridges, it is clear that each has its own strengths and weaknesses.

The .338 Lapua is a high-powered, long-range cartridge that is well-suited for long-range competitions and hunting large game at extreme distances. It has a higher muzzle energy, flatter trajectory, and better resistance to wind drift and air resistance than the .308 Winchester.

On the other hand, the .308 Winchester is a versatile cartridge that is widely used for hunting and target shooting at medium distances. It has a lower recoil, lower cost, and wider availability of ammunition than the .338 Lapua.

Ultimately, the choice between the two cartridges depends on the intended use and personal preferences of the shooter. If long-range precision shooting or hunting large game at extreme distances is the goal, the .338 Lapua is the clear choice.
