Quick Answer
A red dot sight is not the most suitable choice for long-distance deer shooting due to its limited magnification and potential difficulty in acquiring and tracking moving targets at range.
Limited Magnification
A red dot sight is best suited for close-quarters shooting where targets are within 100-200 yards. At longer ranges, the lack of magnification becomes a significant limitation. Most red dot sights offer 1x or 2x magnification, which is not sufficient to effectively engage targets beyond 300-400 yards. In contrast, variable power scopes with 3-12x magnification are more effective for long-range shooting. For example, a 4-12x scope can provide the necessary magnification to spot and engage a deer at 400 yards.
Target Acquisition and Tracking
Red dot sights excel in quickly acquiring and tracking targets at close range due to their parallax-free design and unlimited eye relief. However, at longer ranges, the red dot can be difficult to acquire and track, especially when the target is moving or the shooter is experiencing recoil. This can lead to missed shots or a longer time to recover on target. For example, a deer moving at 20-30 mph can make it challenging to track with a red dot sight at 300 yards.
Compensating for Range and Motion
While a red dot sight may not be the best choice for long-distance deer shooting, it can still be effective if the shooter is skilled and experienced. One way to compensate for the limited range and motion of a red dot sight is to use a high-powered rifle with a flat trajectory, such as a .30-06 or .308 Winchester. Additionally, using a rifle with a recoil-reducing stock and a bipod or tripod can help the shooter recover on target more quickly.
