How to determine if your rifle is accurate enough for long-range?

Question

Accepted Answer

Establishing a Baseline Before testing your rifle’s long-range accuracy, make sure it’s properly maintained and sighted in. This includes ensuring the barrel is clean, the action is well-lubricated, and the scope is properly adjusted for your specific rifle and optics. It’s also essential to have a consistent shooting form and stance. To establish a baseline, fire a series of shots at 100 yards and measure the group size. A group size of 1-2 inches at this distance is a good starting point for long-range hunting. If your rifle is not meeting this standard, consider adjusting your sight picture or consulting a firearms professional for guidance.
Long-Range Testing and Evaluation For long-range testing, start at 200 yards and gradually increase the distance to 300 and 400 yards. Use a spotting scope or a high-powered binocular to observe the impact zone and measure the group size. A well-accurate rifle should consistently shoot within 2-4 inches at 300 yards, and 4-6 inches at 400 yards. To further evaluate your rifle’s accuracy, consider using a chronograph to measure the muzzle velocity and a ballistic calculator to determine the effects of atmospheric conditions, such as wind and humidity, on your shot. This will help you adjust your aim and compensate for external factors that may affect your shot’s trajectory.
Ballistic Compensation and Adjustment To accurately compensate for atmospheric conditions, use ballistic software or a ballistic calculator to determine the effects of wind, humidity, and air density on your shot. This will allow you to make precise adjustments to your aim, taking into account the distance, rifle caliber, and bullet type. A general rule of thumb is to adjust your aim 1 MOA (1.047 inches at 100 yards) for every 10 mph of wind at 100 yards. For long-range hunting, it’s essential to understand how these external factors will affect your shot and make adjustments accordingly.
