$44.79
Underwood Ammo 916 InterLock 45-70 Government +P ammunition delivers serious stopping power for hunters and shooters working with lever-action rifles and single-shot platforms chambered in this classic cartridge. The 300-grain jacketed hollow point bullet is built for controlled expansion and deep penetration on game, making it a trusted choice for hunting applications where reliability and terminal performance matter. Whether you're hunting elk, moose, or taking long-range shots in rough country, this hot-loaded +P round pushes the 45-70 platform to its upper performance envelope.
The InterLock bullet design is a proven performer in the field. The jacket-to-core construction resists separation and promotes consistent mushrooming, which means better energy transfer and more predictable wound channels. The hollow point initiates rapid expansion while the heavy 300-grain mass maintains momentum downrange—a combination that appeals to hunters who demand results from their ammo, not excuses.
Underwood Ammo is known for loading ammunition to higher pressures than some factory loads, so if your rifle is rated for +P ammunition, you'll get extra velocity and energy. Each box contains 20 rounds, and this product ships in a 10-box case, making it practical for hunters and range shooters who like to stock up. Whether you reload or prefer factory ammunition, Underwood's quality control and consistent performance have built a solid reputation among serious hunters and sport shooters.

Frequently Asked Questions
Is this ammunition safe for my 45-70 rifle?
The +P designation indicates this ammunition is loaded to higher pressures than standard 45-70 ammunition. Verify your rifle is rated for +P loads before shooting. Most modern 45-70 rifles (especially lever-actions designed for modern loads) are compatible, but always check your firearm's manual or manufacturer specifications to be certain.
What's the difference between InterLock and standard hollow point bullets?
InterLock bullets feature a mechanical connection between the jacket and lead core that resists separation during impact. This design promotes more consistent expansion and deeper penetration compared to some traditional hollow point designs, which is why many hunters prefer them for big game.
How much ammunition is in a case?
Each case contains 10 boxes of 20 rounds, for a total of 200 rounds per case order.
Is this suitable for hunting?
Yes. The 300-grain hollow point bullet and +P loading make this ammunition appropriate for hunting applications where the 45-70 is used, particularly for larger game and where heavier bullet weight and controlled expansion are priorities.
