Quick Answer
To determine if your .22-250 is accurate enough for coyotes, shoot at least three groups at 100 yards with a consistent load and rifle setup, then measure the group size. A group size of 1 inch or less is a good starting point. If you're not getting consistent sub-moa groups, consider optimizing your load and rifle setup.
Establishing a Baseline
To accurately assess your .22-250’s performance, start by establishing a consistent load and rifle setup. This means using the same ammunition, barrel, and scope settings for each shot. Begin by shooting three groups at 100 yards, with at least 10-15 rounds in each group. This will give you a baseline for your rifle’s accuracy.
Measuring Group Size
To measure group size, use a scope with a reticle that allows for precise ranging and measurement. You can also use a shot timer and a rangefinder to ensure accurate calculations. For each group, measure the center-to-center distance of the shots to determine the group size. In the case of coyote hunting, a group size of 1 inch or less is a good starting point. This translates to a 10-shot group with a 2-moa spread or smaller.
Optimizing Your Load
If you’re not getting consistent sub-moa groups, consider optimizing your load. Start by adjusting your powder charge to find the optimal load for your rifle. Aim for a charge that produces a consistent velocity of around 3,000-3,200 fps. You can also experiment with different bullet weights and types to find the best combination for your rifle. Keep in mind that even small changes in load can significantly impact accuracy, so be sure to test and verify any changes before heading out to hunt.
