Weatherby Select 30-378 Wby Mag 180gr Hornady Interlock Ammo

The Weatherby Select 30-378 Weatherby Magnum ammunition delivers exceptional long-range performance with 180-grain Hornady Interlock bullets engineered for controlled expansion and deep penetration. This premium hunting cartridge transforms the potent 30-378 Weatherby Magnum into a precision tool for taking large game at extended distances.

What Makes This Different

Weatherby Select ammunition combines factory-loaded precision with Hornady's proven Interlock bullet technology, featuring a mechanical lock ring that prevents core-jacket separation during expansion. The 180-grain bullet weight provides optimal sectional density for the 30-378 Weatherby Magnum case capacity, delivering flatter trajectory and higher retained energy than standard 30-caliber hunting loads. Quality control standards ensure consistent velocities and accuracy that matches custom handloads.

Key Features

• 180-grain Hornady Interlock bullets with mechanical core-jacket lock ring
• 30-378 Weatherby Magnum case delivers approximately 3,420 fps muzzle velocity
• Premium brass cases with consistent wall thickness and flash hole uniformity
• Factory-loaded to SAAMI specifications for reliable chambering and extraction
• 20 rounds per box packaging for convenient range sessions
• Boxer-primed cases suitable for reloading after firing

The 30-378 Weatherby Magnum cartridge excels in long-range hunting scenarios where shot placement at 400+ yards determines success. The high ballistic coefficient of the 180-grain Interlock bullet maintains supersonic velocity beyond 1,200 yards, while controlled expansion ensures reliable terminal performance on elk, moose, and other large game. Temperature-stable powder formulation maintains consistent performance from arctic conditions to desert heat.
