Which caliber is used by the Navy SEALs for their primary sniper rifle?

The primary caliber used by Navy SEALs for their sniper rifles is often the .338 Lapua Magnum. This caliber is recognized for its long-range accuracy and superior stopping power, making it an excellent choice for sniper operations where both precision and lethality are critical. The .338 Lapua Magnum allows shooters to engage targets effectively at extended distances, which is essential for the types of missions that Navy SEALs typically undertake.

In the context of sniper engagements, the .338 Lapua Magnum offers a flatter trajectory and reduced wind drift compared to some other calibers, enhancing the SEALs' capabilities in various operational environments. This precision contributes to successful missions where targeting enemy personnel or material from long distances is required. The development of this caliber was specifically aimed at fulfilling the needs of military and law enforcement snipers in terms of accuracy, range, and terminal ballistics.

While other calibers like .308 Winchester and 7.62x51mm NATO are used in military applications, they typically do not match the range and effectiveness of the .338 Lapua Magnum for sniper operations at extended ranges. The .50 BMG is primarily utilized for heavier anti-material roles rather than precision sniping, which makes it less suitable for standard sniper use.
