When it comes to long-range precision shooting and hunting, the .338 Lapua and .338 Win Mag calibers have established themselves as two popular choices in the firearms community. Both cartridges boast impressive ballistics and are adept at taking down large game with precision and power. However, for those considering which caliber to choose, it may seem overwhelming to decipher the differences and determine which option best suits their needs. In this blog post, we dive into the specifics of these two cartridges, highlighting areas such as origins, ballistics, ammunition and rifles, as well as their individual advantages and disadvantages.
The Origins of .338 Lapua and .338 Win Mag
.338 Lapua
The .338 Lapua Magnum, also known as the .338 LM or 8.6x70mm, was initially developed for military snipers during the 1980s by the Finnish company Lapua. Their goal was to create a high-powered cartridge that offered consistent accuracy at extreme long-range distances. The .338 Lapua was a result of this pursuit, and since then, this cartridge has earned its place as a go-to option for military and law enforcement snipers, as well as civilian long-range shooters and hunters.
.338 Winchester Magnum
Introduced in 1958 by the American company Winchester, the .338 Winchester Magnum, commonly referred to as the .338 Win Mag, was the first of the .338 caliber family to gain commercial success. This cartridge effectively bridged the gap between the .30 caliber and the larger .375 H&H Magnum, offering hunters a reliable and effective round for large and dangerous game. Since its introduction, the .338 Win Mag has become a popular choice with hunters and long-range enthusiasts alike.
Comparing Ballistics: Velocity and Energy
Velocity
The .338 Lapua Magnum has undoubtedly been designed with long-range, high-energy shooting in mind. With a muzzle velocity of up to 3,000 feet per second (fps), the Lapua can maintain supersonic speeds at distances greatly surpassing 1,000 yards. In comparison, the .338 Win Mag is no slouch either, offering a muzzle velocity of around 2,800 fps. However, its velocity will drop below supersonic levels at closer to 1,000 yards.
Energy
Both calibers perform impressively when considering energy output. The .338 Lapua, using a typical 250-grain bullet, will deliver upwards of 4,800 ft-lb of energy at the muzzle, making it a superior option for larger game or long-range shooting. In contrast, the .338 Win Mag, firing a 225-grain bullet, will generate about 4,000 ft-lb of energy at the muzzle. While not as powerful as the Lapua, the Winchester Magnum still boasts adequate energy performance for most hunting applications, even for larger game.
Ammunition and Rifles
Ammunition
Both .338 Lapua and .338 Win Mag cartridges are available in various bullet weights and designs. For long-range precision shooting, there are match-grade bullets available for both calibers, with the Lapua catering to more high-end, specialized options. When it comes to hunting, there is a wide range of bullet options designed for controlled expansion and maximum energy transference.
It should be noted that the .338 Lapua ammunition is generally more expensive than .338 Win Mag due to its specialty nature and higher material quality. However, this price difference becomes less of a factor for reloaders who can tailor their custom rounds to a specific requirement.
Rifles
There is an extensive variety of rifles available chambered for both .338 Lapua and .338 Win Mag. Many popular manufacturers such as Remington, Savage, and Ruger produce rifles in both calibers. However, due to its military origins, there are more precision and tactical rifles chambered in .338 Lapua than .338 Win Mag. Meanwhile, you will find more hunting rifles available for the Winchester Magnum.
Recoil Management
The .338 Lapua carries significantly more recoil than the .338 Win Mag, primarily due to its heavier bullet weight and higher velocities. The Lapua’s recoil energy is typically around 45 ft-lb or higher, depending on the rifle, while the Win Mag generates around 30 to 35 ft-lb of recoil energy. Shooters who are sensitive to recoil may find the Lapua too aggressive, which could impact their ability to maintain consistent accuracy during practice or a hunt.

In conclusion, the choice between .338 Lapua and .338 Win Mag largely comes down to an individual’s specific requirements, such as intended use, range, and even budget. The .338 Lapua is more suited for extreme long-range shooting and the precision rifle market, whereas the .338 Win Mag offers a solid option for large-game hunting at moderate to long-range distances. By carefully considering each caliber’s strengths and weaknesses, shooters can confidently make an informed decision on the cartridge best suited for their needs.
Frequently Asked Questions
What is the difference between 338 Lapua and 338 Win Mag?
The primary difference between these two cartridges is their overall design and purpose. The .338 Lapua Magnum is designed specifically for military long-range sniper rifles and precision shooting, whereas the .338 Winchester Magnum is a larger, more versatile round used for big game hunting. The .338 Lapua generally has a higher muzzle velocity and is capable of shooting accurately up to longer distances.
What is the effective range of a 338 Win Mag?
The effective range of the .338 Winchester Magnum depends on the specific rifle and ammunition being used, as well as factors such as the shooter’s skill level and environmental conditions. However, the typical effective range for this cartridge falls between 400 to 800 yards for hunting purposes, with skilled shooters being able to achieve accurate shots past 1,000 yards in some cases.
What is the difference between 300 Win Mag and 338 Lapua?
The main difference between the .300 Winchester Magnum and the .338 Lapua Magnum is the caliber size and intended use. The .300 Win Mag is a popular big-game hunting cartridge designed for long-range shooting, while the .338 Lapua Magnum is designed for military and law enforcement sniper applications. The .338 Lapua is capable of shooting heavier bullets at higher velocities, offering better aerodynamic performance and more kinetic energy at long range compared to the .300 Win Mag.
What is more powerful than a 338 Lapua?
Several cartridges are more powerful than the .338 Lapua Magnum, including the .50 Browning Machine Gun (.50 BMG), the .416 Barrett, and the .375 CheyTac, among others. These cartridges typically have larger calibers, heavier projectiles, and higher muzzle velocities, giving them more power and extended range than the .338 Lapua.
