Known as the fastest production.30 Caliber available on the market
The 30-378 was designed & tested in late 1959 – early 1960 by Weatherby at the request of the United States Army for the Redstone Arsenal in Huntsville, Alabama. Loads were to be developed to exceed 4000 FPS & as close to 5000FPS*.
When it was commercially introduced in 1996, it was billed as the world’s fastest 30 caliber cartridge and will push a 30 caliber bullet 3,500 feet per second.
Hornady® InterLock®
The InterLock® features an exposed lead tip for controlled expansion and hard-hitting terminal performance. A secant ogive design — one of the most ballistically efficient profiles ever developed. The raised ring inside the jacket is embedded in the bullet, combined with the one-piece core, keeps the core and jacket locked together during expansion to retain mass and energy.
