The Difference between the 338 Win Mag and 338 Lapua

The .338 Win Mag and .338 Lapua are two of the most popular magnum cartridges used for long range shooting. Although these two rounds have some similarities, there are a number of differences between them that can be important to consider when selecting one for a particular purpose.

The .338 Win Mag is a magnum cartridge based on the .308 Winchester round and was designed to provide increased performance and long-range accuracy over the .308. It has been used for hunting, long-range target shooting, and even in some military applications. The bullet diameter of this round is .338 inch, the same as the .338 Lapua, but the case size and powder charge are much smaller. This results in a lower muzzle velocity and a shorter effective range than the .338 Lapua.

The .338 Lapua is a much more powerful and accurate round based on a larger case size and a significantly larger powder charge. This round was designed to provide extreme long range accuracy, and it has a muzzle velocity of around 3,000 feet per second. It has been used extensively in military applications and in long-range target shooting and hunting.

The biggest difference between the .338 Win Mag and .338 Lapua is the amount of energy delivered by the rounds when they reach their target. The .338 Win Mag has a maximum energy of around 4,500 foot-pounds, whereas the .338 Lapua can deliver up to 8,800 foot-pounds of energy. This makes the .338 Lapua significantly more effective at longer ranges, as the increased energy helps to compensate for the bullet drop.

The other notable difference between the two cartridges is their recoil. The .338 Win Mag has a much lower recoil than the .338 Lapua, and it is much easier to shoot accurately. This makes the .338 Win Mag an excellent choice for hunting, target shooting, and even some military applications.

In conclusion, the .338 Win Mag and .338 Lapua are both powerful magnum cartridges with a number of differences. The .338 Win Mag is a good choice for hunting, target shooting, and some military applications due to its lower recoil and shorter effective range. The .338 Lapua is a much more powerful round that is better suited for longer range shooting, as the increased energy helps to compensate for bullet drop.

Difference between 338 Win Mag and 338 Lapua

Case Capacity and Design

The 338 Win Mag is an inherently shorter cartridge than the 338 Lapua, measuring 2.60 inches as opposed to the latter’s 3.60 inches. This difference in length is primarily due to the fact that the 338 Lapua has a much larger case capacity than the 338 Win Mag. The 338 Lapua can hold up to 140 grains of powder, whereas the 338 Win Mag has a maximum capacity of around 100 grains. Additionally, the 338 Lapua has a much longer neck than the 338 Win Mag, allowing for a longer bullet seating depth and a higher muzzle velocity.

Ballistic Performance

Due to the difference in case capacity, the 338 Lapua offers significantly better ballistic performance than the 338 Win Mag. The Lapua is capable of pushing projectiles at a velocity of around 2,900 fps, whereas the Win Mag has a maximum velocity of around 2,600 fps. The 338 Lapua also has a higher BC than the 338 Win Mag, meaning that it is better suited for long-range shooting.

Recoil

The 338 Lapua is also more powerful than the 338 Win Mag, resulting in a significantly higher recoil. The Lapua’s recoil is around 25-30 ft/lbs, whereas the Win Mag has a recoil of around 15-20 ft/lbs. Additionally, the Lapua’s higher muzzle velocity and higher BC result in a flatter trajectory than the Win Mag, making it more suitable for long-range shooting.
