What is likelihood of needing a follow-up shot on bison?

April 5, 2026

Quick Answer

The likelihood of needing a follow-up shot on bison is low to moderate, especially with proper shot placement and penetration, but can increase if the bullet doesn't reach the vitals or if the animal is shot at close range. Studies suggest that well-placed shots on bison have a success rate of around 90-95%. However, the effectiveness of a follow-up shot can be greatly reduced if the first shot is not well-placed.

Shot Placement and Penetration

When hunting bison, shot placement is critical, and a well-placed shot to the heart or lungs can be fatal with a single shot. Aim for the center of the chest, about 1-2 inches above the midpoint between the front legs. A bullet that penetrates at least 12-18 inches and expands to around 1-2 times its original diameter is recommended for a quick and humane kill. Use a rifle with a minimum caliber of .300 Magnum and a bullet weight of 150-200 grains.

Factors Affecting the Need for a Follow-up Shot

Several factors can influence the need for a follow-up shot on bison, including the distance from the shooter, the angle of the shot, and the animal’s movement at the time of the shot. Shots taken at close range (less than 50 yards) are more likely to require a follow-up shot, as the bullet may not have enough time to expand and reach the vitals. Shots taken at an angle or when the bison is moving can also increase the likelihood of a follow-up shot, as the bullet may not enter the animal’s body at a perpendicular angle and penetrate to the desired depth.

Best Practices for Hunting Bison

To minimize the need for a follow-up shot on bison, follow best practices for hunting these animals. Make sure to choose a rifle with a flat trajectory and a reliable bullet that can penetrate deep into the animal’s body. Use a high-quality scope with a clear view of the target, and aim for the center of the chest. Consider hunting with a spotter or a guide who is experienced in hunting bison, as they can provide valuable advice on shot placement and penetration.
