Yes, a heavier BB has a more stable flight path. They are more accurate, allow you to shoot greater distances and have a greater ability to punch through soft cover such as leaves and branches. They do fly slower than lighter BB's however and if you use a BB that is too heavy people are able to "matrix" out of the way at greater distances.
The goal is to find the fight weight for your set up.
