What impact does a suppressor have on .45-70 accuracy and recoil?

Accuracy Impact

A suppressor’s effect on .45-70 accuracy is generally minimal, with most shooters reporting no significant difference in groups at 100 yards or longer. However, the added weight of the suppressor can cause a slight shift in the rifle’s point of impact, typically in the range of 1-3 inches at 100 yards, depending on the rifle’s design and the suppressor’s mounting system. To mitigate this effect, it’s recommended to re-zero the rifle after installing a suppressor.

Recoil Impact

The suppressor’s impact on recoil is more noticeable. The added weight of the suppressor can increase the rifle’s overall recoil energy by around 10-20%, depending on the suppressor’s design and the rifle’s weight. This increased recoil can make the rifle more difficult to handle, particularly for shooters with smaller frames or those who are not accustomed to shooting heavy rifles. To manage this increased recoil, shooters can use heavier loads, such as 300-grain bullets, which tend to produce less recoil than lighter loads.

Practical Considerations

When choosing a suppressor for a .45-70 rifle, look for models specifically designed for hunting applications, which typically feature a longer barrel and a more robust design to handle the increased recoil and stress of hunting use. Also, consider the can’s diameter and length, as well as the mounting system, to ensure a secure and repeatable zero. In terms of shooting technique, shooters can use a slower, more controlled follow-through to help manage the increased recoil and maintain accuracy.
