What should you do when changing from 150-grain to 180-grain ammunition?

When switching from 150-grain to 180-grain ammunition, it is essential to sight your rifle again because different bullet weights can significantly affect the trajectory and point of impact. Bullets of varying weights will have different velocities and ballistic characteristics, which means that a rifle sighted in for one weight may not shoot accurately with another.

By resighting the rifle, you ensure that your aim accounts for these differences, resulting in better accuracy and consistency when shooting. This practice enhances your effectiveness as a hunter by ensuring that your shots are on target, which is crucial for ethical hunting and game management.

In contrast, simply changing scope settings without resighting may lead to inaccuracies since those settings are typically calibrated for specific ammunition weights. Therefore, it is more critical to carry out the entire resighting process.
