Description
Remington engineered this .45-70 subsonic ammunition for one job: delivering consistent quiet performance from a suppressed rifle without the supersonic crack that standard loads create. The 300-grain bonded hollow point is loaded to approximately 1080 fps using custom-tuned powders and dependable primers that ensure shot-to-shot consistency even in varying atmospheric conditions.
Subsonic Performance Built for Suppressors
When a bullet travels faster than roughly 1,125 fps, it generates a sonic crack that no suppressor can fully eliminate. This subsonic load stays well below that threshold, giving you the truly quiet shooting experience suppressors promise. The enclosed-base bullet design reduces lead buildup in suppressor ports, keeping your can cleaner over extended shooting sessions and extending its service life. The combination of custom powders and primers ensures this load performs reliably, whether you're shooting in cold weather or at elevation.
Reduced Recoil, Easier Follow-up Shots
The lighter velocity and heavier bullet means significantly less shoulder punishment compared to standard .45-70 loads. This makes follow-up shots easier and more accurate, especially important in hunting situations or when shooting unsupported from field positions. The lower recoil also reduces shooter signature—when combined with suppression, you're operating with minimal noise and minimal disturbance. The bonded construction keeps the bullet intact through barriers or tough conditions without fragmenting unpredictably.
Proven Versatility Across Rifle Types
This ammunition works reliably in lever-action rifles like the Marlin 1895 and Henry, as well as modern .45-70 platforms. Subsonic loads maintain momentum through mass rather than speed, making them effective for short-range hunting and tactical applications where a suppressed, quiet rifle is essential. The 300-grain weight is a practical sweet spot for feeding reliably across most .45-70 rifles while delivering downrange authority when you need it.

Frequently Asked Questions
What makes this subsonic .45-70 different from standard loads?
This round is loaded to approximately 1080 fps—below the speed of sound—which eliminates the sonic crack that suppressors cannot silence. Standard .45-70 loads run 1,300 to 2,000 fps and produce that supersonic report even with a suppressor. The enclosed-base bullet also reduces lead fouling in suppressor ports, keeping your can running cleaner longer.
Will the 300-grain subsonic load work in my lever-action rifle?
Yes, this ammunition feeds reliably in lever guns like the Marlin 1895 and Henry, as well as modern .45-70 rifles. Most .45-70 rifles are designed to handle subsonic loads without any issues. If you have an older rifle with a slower barrel twist rate (1:28), check your specific rifle's specifications, though most modern lever-actions use the standard 1:20 twist and have no problems.
Is this round suitable for hunting with a suppressor?
Absolutely. The 300-grain bonded hollow point maintains solid downrange performance at subsonic velocity for close- to medium-range hunting applications. Combined with suppression, you get a quiet, hard-hitting round ideal for hog hunting, predator control, or situations where noise management is critical. The bonded construction ensures reliable expansion and penetration even at these lower velocities.
How much recoil can I expect compared to standard .45-70 ammunition?
Significantly less. Subsonic loads trade velocity for quiet operation, which means considerably softer recoil that's gentler on your shoulder and easier to control for follow-up shots. This makes the round more pleasant to shoot and improves accuracy, especially when firing from unsupported field positions.
