Weatherby 30-378 WBY 195 Grain Hammer Custom Rifle Ammo 20 Rounds

In the realm of high-velocity cartridges, few can claim a lineage as distinguished as the Weatherby .30-378. Born from innovation in 1959 by Roy Weatherby himself, this cartridge emerged at the behest of the United States Army. It stands as a testament to ballistic excellence and precision engineering.

The .30-378 Weatherby Magnum is not merely an iteration; it is a revolution based on its parent case—the formidable .378—necked down to accept a 30 caliber bullet. This transformation results in an extraordinary combination: raw power married with remarkable speed. Originally acclaimed as the world's fastest 30 caliber offering, it propels its projectile at an astonishing velocity of 3,500 feet per second.

After years in relative obscurity following its initial creation, this powerhouse was reintroduced into production by Weatherby in 1996. Its resurgence has fortified its place among elite long-range cartridges for those who demand unparalleled performance from their rifles.

For hunters and marksmen alike, choosing the .30-378 means embracing both heritage and cutting-edge capability—a choice for those who understand that every shot fired must be decisive.
