What does a heavy bullet "slipping and grabbing" refer to?

The term "slipping and grabbing" in relation to a heavy bullet refers to its behavior concerning the barrel's rifling when fired. A heavy bullet typically has a higher mass and thus generates more momentum, which can lead to a more consistent and stable flight path once it engages the rifling.

This concept is better known in the context of "high finish." This indicates that the bullet is designed with optimal dimensions and surface finishes that allow it to grip the rifling effectively without excessive resistance. A high-quality finish on the bullet helps reduce friction and wear on the barrel while ensuring that the bullet engages with the rifling correctly, allowing for improved accuracy and consistency.

This performance is crucial for precision shooting, as better engagement with the rifling leads to more predictable trajectories and can enhance overall shooting accuracy. The other options do not adequately capture the significance of how the finish of the bullet affects its interaction with the barrel and, consequently, its performance in terms of accuracy.
