The Underwood Ammo 916 Interlock 45-70 Government +P 300gr Jacketed Hollow Point is engineered as a modern, high-performance hunting load for rifles chambered in 45-70 Government. Built around the Hornady Interlock jacketed hollow point bullet and nickel-plated brass cases, this cartridge is designed to deliver reliable expansion, deep penetration, and smooth feeding in contemporary rifles.

This load is tailored for medium to large game hunting where controlled expansion and strong energy transfer are essential. The Interlock bullet’s locking ring helps the core and jacket stay together during expansion, retaining weight and momentum for consistent terminal performance. With supersonic muzzle velocity and substantial muzzle energy, it is suitable for modern 45-70 rifles in good condition and is not intended for antique firearms. Underwood Ammo is known for precise manufacturing, rigorous field testing, and attention to detail that gives hunters confidence in every shot.
