This specific type of ammunition represents a classic choice for the .45-70 Government cartridge, a powerful round developed in 1873 for the U.S. Army’s Springfield Trapdoor rifle. A projectile weighing 405 grains, typically made of lead or a lead alloy, signifies a traditional loading replicating the original military specification. Intended for handloading, these projectiles offer enthusiasts the opportunity to tailor ammunition to their specific firearms and applications, from hunting large game to target shooting.
The historical significance of this projectile weight, combined with the .45-70 cartridge’s enduring popularity, contributes to its continued use. This combination provides a substantial amount of kinetic energy, making it suitable for taking down large, tough game. Handloading allows for customization of powder charges, resulting in optimized performance and tailored recoil characteristics. This degree of control can be particularly valuable for hunters seeking ethical harvests and long-range accuracy.
