Remington Subsonic Features The Remington Subsonic line s enclosed-base bullet construction is specifically engineered to reduce lead buildup inside a suppressor a detail that keeps a shooter s can performing at its best across many rounds rather than fouling quickly the way a standard exposed-base bullet might. Custom-tuned powders are matched to the subsonic velocity target for this cartridge ensuring the round burns consistently and cycles reliably even though it operates well below the speed of sound. Dependable primers support consistent ignition at these tuned subsonic pressures an important detail since subsonic loads run on a narrower performance margin than standard supersonic ammunition. The boat tail hollow point bullet design promotes reliable expansion while its tapered base helps maintain stability even at reduced subsonic velocities. Remington engineered this Subsonic line to outperform competing subsonic offerings giving hunters and shooters adaptable performance across hunting training and tactical applications in virtually any environment where reduced signature matters. Chambering this technology in the classic 45-70 Government gives shooters running a lever action or single shot rifle in this big bore cartridge the same quiet low-signature performance available in more modern chamberings. This combination of quiet operation and dependable terminal performance reflects Remington s broader effort to build subsonic ammunition that performs as well suppressed as standard ammunition does unsuppressed.
