Federal American Eagle Subsonic .45-70 Government 300 Grain Target Soft Point Ammunition (MPN: 4570SUB1)
Product Description
Shooting a classic lever-action or modern threaded rifle chambered in .45-70 Government with a sound suppressor often presents a distinct acoustic issue: traditional full-power big-bore loads break the sound barrier with an intense supersonic crack, resulting in heavy blast report and sharp shoulder recoil. Federal eliminates this friction with their American Eagle Subsonic .45-70 Government 300-grain Target Soft Point load. Engineered specifically to stay below the speed of sound, this specialized cartridge provides suppressed rifle shooters with an exceptionally quiet, low-recoil range round that makes heavy-caliber shooting significantly more enjoyable.
Proudly loaded in Anoka, Minnesota, this centerfire rifle cartridge features a heavy 300-grain Target Soft Point (TSP) projectile. Federal carefully meters clean-burning propellants to maintain velocities below the speed of sound while ensuring complete powder combustion to prevent unburnt powder buildup inside suppressor baffles. Every round is seated into first-run, heavy-walled virgin brass cases fitted with ultra-responsive Boxer primers. The clean brass casings provide a tight chamber seal to prevent blowback gas around the action, ensuring smooth mechanical cycling in lever-action and single-shot platforms while supplying prime raw components for the reloading bench.
Out on the range, this subsonic .45-70 load delivers a dramatically reduced recoil profile compared to standard high-velocity options, allowing shooters to stay on target for rapid follow-up alignments. Leaving the muzzle at a uniform subsonic velocity of 1,010 FPS with 679 ft-lbs of muzzle energy, it produces a whisper-quiet report when paired with a quality suppressor. The heavy soft point bullet design provides predictable downrange tracking and clean target punch-holes on steel and paper targets. Packaged in a compact 20-round box, it stands out as an essential, high-reliability option for quiet target diagnostics, suppressed range training, and recreational shooting.
*Armorer Bench Notes & Technical Maintenance Guidance: Centerfire rifle ammunition procurement regulations strictly apply. All purchasers must be 21 years of age or older and assume full legal responsibility for adhering to local, state, and federal laws. Due to commercial carrier transit restrictions, ammunition cannot be delivered to Alaska, Hawaii, or US territories. Deliveries destined for California and New York must ship directly to an authorized FFL dealer or registered ammunition vendor. Residents of Illinois must supply a valid FOID card alongside a matching state ID prior to order processing, and localized regional bans prohibit delivery to specific jurisdictions inside Illinois (including Chicago), Massachusetts, Connecticut, and Washington D.C. Armorer Tip: Subsonic .45-70 loads feature a steeper trajectory drop than high-velocity rounds; establish a dedicated zero for your optics or iron sights when switching between subsonic and supersonic loads to ensure accurate downrange placement.
