Description
This is a full-pressure load designed for modern lever-action rifles and other platforms that can handle the 45-70's substantial recoil and power. With a 300-grain semi-jacketed hollow point bullet, the round delivers the kind of terminal performance hunters expect from a cartridge that's been proven in the field for over 150 years.
Remington's High Performance .45-70 Construction
Remington assembles each cartridge with premium components and builds them to tight tolerances. The brass cases are new production and Boxer-primed, which means they're reloadable if that's something you plan to do down the road. The combination of quality materials and precise assembly is what puts Remington's High Performance line on the shelf next to more expensive specialty loads while delivering comparable reliability.
Velocity and Terminal Performance
The semi-jacketed hollow point bullet reaches 1900 feet per second from the muzzle with 2405 foot-pounds of energy. That velocity level gives you the power to take deer and elk at reasonable hunting distances while staying within the bounds of what a modern strong-action lever gun can handle. The hollow point design encourages expansion on impact while the partial copper jacket ensures deep penetration through heavy bone and muscle.
What to Expect from Full-Pressure Loads
Because this is a full-pressure loading, your rifle needs to be a modern, strong-action gun designed for the 45-70. Classic firearms like original Trapdoor Springfields cannot safely handle ammunition at this power level. If you're unsure whether your rifle can handle full-pressure 45-70 ammunition, check your firearm's manual or contact the manufacturer before shooting.
