This guide, presented by Karl Erickson of Tactical Rifleman, emphasizes the importance of using 5-round groups for zeroing firearms, arguing that 3-round groups are often insufficient. He explains how to analyze shot placement on a target to distinguish between mechanical rifle accuracy and shooter-induced errors, preventing unnecessary sight adjustments. The instruction is delivered with high authority, drawing on military marksmanship standards.

Quick Summary

Using 5-round groups for rifle zeroing is recommended over 3-round groups because it provides more data to differentiate between the rifle's mechanical accuracy and shooter errors. This prevents unnecessary sight adjustments based on potentially misleading small groups, ensuring a more accurate and stable zero.

Frequently Asked Questions

Why are 5-round groups better for zeroing a rifle than 3-round groups?

Five-round groups provide a larger data set, making it easier to distinguish between the rifle's inherent mechanical accuracy and errors introduced by the shooter. This prevents making unnecessary sight adjustments based on limited or misleading information from smaller groups.

How can I tell if my shot group is due to shooter error?

If your rifle is capable of dime-sized groups at 25 meters (like the M16A2/M4), a larger or triangular 3-round group often indicates you are pulling shots. Analyzing the pattern of the group can reveal consistent directional errors.

What happens if I adjust my sights based on a bad 3-round group?

Adjusting sights based on insufficient data from a 3-round group can lead to chasing an inaccurate zero. You might end up making multiple corrections that move the point of impact randomly across the target, rather than achieving a stable and true zero.
