Quick Answer
To conduct a cold bore shot test, start by placing the rifle at a consistent distance from the target, usually around 100 yards. Shoot a single shot and then immediately inspect the impact, taking note of any deviations from point of aim. Repeat this process several times to ensure accuracy.
Setting Up the Test
To begin a cold bore shot test, ensure your rifle is sighted in accurately and that the environment is calm with minimal wind. Place the rifle at a consistent distance from the target, traditionally 100 yards, and use a high-quality scope or rangefinder to measure the impact. Use a consistent shooting position and stance to maintain accuracy.
Conducting the Test
Shoot a single shot from a cold bore, meaning the barrel has had no shots fired from it in at least 30 minutes. Immediately inspect the impact, noting any deviations from the point of aim. If the shot group is outside of 1 MOA (minute of angle), consider it a cold bore shot test failure. Repeat the process several times to ensure accuracy and identify any pattern or trends in the shot impacts. Keep track of the time between shots to ensure the barrel is truly cold.
Analyzing the Results
Compare the shot impacts to your sight-in data to identify any deviations or trends. If the impacts are consistently off-target, consider adjusting your scope or rifle to compensate. If the impacts are random and inconsistent, it may indicate a problem with your shooting technique or rifle setup. Take note of any changes in weather or environmental conditions that could be affecting the shot impacts, and adjust your test accordingly.
