What differences are there between .338 Federal and .338 Lapua?

Case Length and Performance

The .338 Federal has a case length of 2.059 inches, while the .338 Lapua has a case length of 2.015 inches. This difference in case length affects the performance of the cartridges. The .338 Lapua has a longer case to seat the heavier bullet, which contributes to its flatter trajectory and more accurate performance at longer ranges. In contrast, the .338 Federal has a shorter case, which limits its maximum effective range but makes it more suitable for hunting larger game at closer ranges.

Hunting Large Game with the .338 Federal

When hunting elk with the .338 Federal, it’s essential to use the right ammunition. Look for bullets with a controlled expansion design, such as the Hornady SP or the Winchester Power Point. These bullets are designed to expand consistently and provide deep penetration, making them well-suited for taking down larger game like elk. When choosing a load, aim for the 200-220 grain range, which provides enough kinetic energy to take down large game while minimizing the risk of over-penetration.

Long-Range Performance of the .338 Lapua

When using the .338 Lapua for long-range target shooting or hunting at longer distances, it’s crucial to consider the wind and bullet drop. The .338 Lapua has a flatter trajectory than the .338 Federal, but it still requires careful wind deflection and bullet drop compensation. To achieve accurate results, use a high-quality scope with a long-range reticle, and aim to use a 250-300 grain bullet, which provides enough kinetic energy to take down larger game while minimizing the risk of over-penetration.
