The HSM 45-70 Government with Sierra 300-grain JHP/FP bullets is built for hunters who want dependable performance in the field. These rounds pair a proven bullet design with HSM's precision loading for consistency round after round. The 300-grain Sierra hollow point features a flat-nose profile that ensures safe, reliable feeding through tubular magazines while delivering the expansion characteristics that matter when the moment counts.
The 300-grain hollow point flat nose bullet is engineered to expand at the velocities typical of modern 45-70 hunting loads. The flat-nose design isn't just about magazine safety in lever-actions, it's a practical choice that works across different modern rifle actions. The hollow point cavity is sized to deliver controlled expansion without over-penetrating on medium to large game at reasonable hunting ranges. This bullet design has proven itself over decades of use, balancing the terminal performance hunters expect with the reliability the cartridge is known for.
Each round is assembled with tight tolerances that ensure uniform velocity and dependable ignition. The reloadable brass cases mean your investment extends beyond the first shot, which adds value especially for a specialty cartridge like the 45-70. HSM's manufacturing standards keep variations to a minimum, so you get the consistency that translates to predictable performance at the range and in the field. Twenty rounds per box is the standard for this caliber, making these boxes convenient to stock or carry.
Whether you're running a Marlin lever-action, a Ruger single-shot, or a modern rifle in this caliber, the HSM 45-70 Government 300-grain load sits in that practical midrange for versatility. It pairs reasonable recoil with the stopping power the 45-70 is known for, making it suitable for deer, hogs, bear, and other game within the cartridge's effective range. The round works in rifles designed around this classic cartridge, delivering the combination of power and precision that keeps the 45-70 relevant for hunting today.
This ammunition is designed for modern 45-70 rifles including Marlin lever-actions, Ruger single-shots, and similar modern actions. The flat-nose bullet design ensures reliable feeding through tubular magazines. Always verify your specific rifle is in good condition and consult the rifle's manual to confirm compatibility with current production 45-70 ammunition.
The flat-nose design serves multiple purposes: it enables safe loading in lever-action rifles with tubular magazines, provides reliable feeding through most actions, and delivers the terminal performance needed for hunting game. Sierra engineered this profile to expand reliably even at moderate hunting velocities while maintaining the penetration the 45-70 is known for.
