Quick Answer
To zero a .22 WMR rifle, start by setting the rear sight to the lowest mark and the front sight to the highest mark. Shoot a 5-shot group at 25 yards, then adjust the sights accordingly. Repeat the process until the groups converge at 50 yards.
Choosing the Right Ammunition
When zeroing a .22 WMR rifle for predator hunting, it’s essential to use high-quality ammunition with a flat trajectory. Look for rounds with a muzzle velocity of 1,800-2,000 feet per second (fps) and a grain weight of 30-40 grains. Some popular options include the CCI Velocitor 30-grain and the Remington Golden Bullet 32-grain.
Zeroing Technique
To zero the rifle, set the rear sight to the lowest mark and the front sight to the highest mark. This will give you a starting point for adjusting the sights. Shoot a 5-shot group at 25 yards, then adjust the rear sight up or down the next mark, depending on where the group hits. Repeat this process, shooting 5-shot groups at 25-yard increments (50, 75, 100, etc.) until the groups converge at your desired zero distance.
Adjusting for Wind and Elevation
When hunting predators, wind and elevation can significantly affect the trajectory of the bullet. As a general rule, adjust for wind by holding 2-3 inches high for a 10 mph wind. For elevation, adjust by 1-2 inches for every 100 yards of vertical change. Use a ballistic calculator or consult a range chart to determine the exact adjustments needed for your specific rifle and ammunition.
